Introduction Xtension 110 P4 Introduction The Xtension 110 P4 Terminal and the Xtension 110 Double Sided P4 terminal have been designed and tested to meet the evaluation criteria of ENV 1317 Part 4. When correctly installed and maintained, the systems are capable of stopping, containing, or re-directing an errant vehicle in a safe manner to the test criteria. The Xtension technology is used for the tension based P4, D1.1 single and double sided end treatment solutions, rather than compression based terminals. It offers exceptional vehicle control and energy absorbing capabilities in head on impacts, where the energy is absorbed with resistance as the impact head travels along the rope, rather than being transferred down the beams as occurs with other compression based systems. Before Installation Placement and use of the Xtension 110 P4 Terminals should be done in accordance with the guidelines and recommendations set forth in this Manual and other Highways Agency requirements (TD19). Depending upon the application and circumstances at the site, assembly of the system should take a two person crew approximately two hours. The Xtension 110 P4 Terminals are engineered safety devices made up of a relatively small number of parts. Before starting installation ensure that the installer is trained to the required standards and familiar with the components and layout of the systems. Highway Care Limited Page 3 Revision 1E
Site Safety General All Traffic Management requirements should be complied with. All workers should wear required PPE (high visibility vests, steel capped footwear, gloves, hard hats, safety glasses etc. as appropriate). Gloves should be worn at all times and particular care should be taken to avoid galvanizing spikes. All underground services must be located before installation of any posts (reference should be made to HSG 47). Only Authorized trained personnel should operate any plant or equipment. The Impact Head and beams should be securely fastened before turning the friction plate. The Friction Plate should be turned manually with a crow bar and extension handle. Do not attempt to turn by mechanical means. Ensure crow bar is securely held while the 4 locking bolts are tightened. Highway Care Limited Page 4 Revision 1E
Xtension 110 Preparation for Installation General Before installing an Xtension 110 P4 Terminal, ensure that you have all the materials and equipment required for the system and its installation. Ensure that the area where the Xtension 110 P4 is to be installed is prepared so that the ground anchor will not protrude more than 100mm above ground level. A Single Sided Xtension 110 P4 Terminal can be connected to any N2 W-beam system with a working width of W2, W3 or W4 (at the point of connection). To connect to a N2 W5 system please contact Highway Care for details. With the use of an A -06 connection the terminal may also be connected to OBB systems The Xtension 110 Double Sided P4 Terminal should be connected to an N2 W2 system (at point of connection). On both single sided and double sided terminals it is usually easier to begin the installation from the downstream end of the terminal at the point where it joins the existing barrier (post 7), and work towards the impact head. Soil Conditions The Xtension 110 has been designed to be installed in verge and centre reserve locations. The Xtension 110 offers a selection of post and foundation options to allow the system to be installed in a variety of ground conditions. I.e. Driven system, concrete in system, Socket system and surface mounted systems. Tools Required The following tools will be needed: 10mm, 13mm, 17mm, 19mm, 24mm, 30mm, 32mm, 36mm, & 1 1/2 Combination Spanner 8mm Allen key. Sockets up to and including 36mm, Torque wrench, Podger bars, Long crow bar - for turning the friction plate, String line, Tape measure, Marker paint / chalk. Spirit level, Rammers and post drivers (if required). Drill and drilling equipment (if required). Cordless/110v drill with 7mm & 8.5mm drill bit Hammer Most of these tools are commonly in a barrier installers standard tool kit Highway Care Limited Page 5 Revision 1E
Step 1 - Setting Out The Xtension 110 Terminal is essentially a continuation of a corrugated beam barrier or it is possible to attach to a box beam barrier via a connection piece. Pull a string line out to give the desired setback over the length of the system, in a straight line parallel to the traffic face (Figure 1). It is important that the Xtension 110 is set out in a straight line, the system will not perform correctly if set out around a radius or with an angle in the system (see Figure 2). The string line should be set to follow and extend the line of the roadside edge of the system posts. If because of limited space the terminal needs to be angled away from the traffic face to allow the correct set back at the head, this taper should be done in the barrier system the terminal is connected to not in the terminal. Note: The Impact head only protrudes 60mm from the traffic face of the beam. Please note, that all posts except post 1 are offset from the string line. (See figure 3). The double sided terminal uses the same post details as the single sided therefore setting out for the double Xtension is the same as above. The components of the double sided system attach to the back of the single sided system. Figure 1. Highway Care Limited Page 6 Revision 1E
Correct Incorrect Incorrect Incorrect Xtension completely straight Xtension not following straight line Xtension flared away from traffic face Xtension flared towards traffic face Figure 2 Note, this applies to both the single sided and double sided systems. Highway Care Limited Page 7 Revision 1E
Xtension posts are set out as shown in figure 3 below. Please note. Use the holes in the post closest to the Xtension head to hang the beam. Figure 3 Highway Care Limited Page 8 Revision 1E
Step 2 Installing Posts 7-2 Install posts 7 to 2 at their correct spacing, height and off set from the string line. (see figure 3. figure 4 and GA drawings). PLEASE NOTE: Post 2 is different to the standard posts, notches go to the back side of the system and also post 3 is offset further from the string line and the other posts. Posts may be driven, concreted in, socketed or surface mounted. The same posts and layout are used for both the single sided and double sided options. Where sockets are used, the posts must be bolted to the sockets with the supplied M8 fasteners. Figure 4. Pull a string line. Set posts 7-2 with The desired offset. (190mm for posts 2, 4, 5, 6, 7, and 230mm for post 3). If using surface mounted posts, they can be anchored using Highway Care supplied M24 Galv Studding with a minimum embedment depth of 200mm and a suitable chemical resin. An acceptance must be obtained from Highway Care prior to using alternative anchors. Figure 5. Ensure Post 2 has post bolt holes on the side nearest the string line (Notches on the opposite side) Figure 6, Install Standard Posts 3, 4, 5, 6, & 7 Highway Care Limited Page 9 Revision 1E
Step 3 Post 1, Ground Strut and Ground Anchor Install post 1 lower at the correct location so that the required length of post protrudes above the ground, this will be determined by the beam height (Figure 7), and also note the holes for mounting post 1 upper are facing the ground anchor. In some ground conditions it may be possible to drive post 1 lower and upper together, when doing this do not use the M16 x 200 bolt supplied, use a podger bar or some sacrificial fasteners. Use the Ground Strut as a guide to position the ground anchor in the correct position (Figure 8). The ground anchor can then be installed (Figure 9). The ground strut should be level, perpendicular to post 1, parallel to the string line and the holes for the Xtension ropes must line up in the ground anchor and ground strut. (Figure 10). Figure 7. Install Post 1 Bottom. Figure 8. Lay out the Ground Strut to correctly space the Ground Anchor. Figure 9. Install the ground anchor. Figure 10, Post 1 installed. Ensure ground strut is level and perpendicular to Post 1. Highway Care Limited Page 10 Revision 1E
Step 4 Attaching spacer blocks and hanging Connection Beam Before hanging the Connection Beam, the spacer blocks need to be hung on posts 2, 3, 4, 5, 6 and 7. On the double sided system, all spacer blocks are the same as the single except there is a smaller spacer block that is fitted to the rear of post 3 (Figure 12). The Spacer Blocks at post 3 MUST be bolted to the post before hanging the beams, but do not bolt any of the other Spacer Blocks to the posts at this stage. Use the M10 x 240 bolt assemblies for the standard blocks and the M10 x 130 for the shorter block on post 3, it should also be noted that the bolt that holds the beam and spacer block to the rear of post 2 on the double sided system MUST have the large square washer under the nut. These bolts should be passed through the spacer block and then through the post with a washer under the bolt head as well as the nut, always use the hole in the post nearest to the Xtension head for the bolts, the hole towards the safety fence should be left for the tether. The clips on the top of are the spacer blocks are there to assist in holding the blocks in place during installation, if they break off they will not affect the performance of the system. The spacer block tethers should be passed through the hole nearest the barrier system (not the impact head) in the spacer blocks and posts, looped together and secured with the M8 bolt and locking nuts as shown in Figure 11a, 11b & 11c. The tethers for the double sided system are longer and go through both spacer blocks on each post. Fig 11a Fig 11b Fig 11c Fig 12. Double sided tether and smaller spacer block for post 3 Highway Care Limited Page 11 Revision 1E
The connection beam is attached to post 6 using the central slot in the beam, and laps the safety fence beam at post 7. I.e. The connection beam always sits on the traffic face of the system beam. The rope anchor brackets fit inside the valleys of the beam on the rear face at post 7 with the wire rope mounting holes towards the head, as shown in figure 13. The beam is fixed to posts 6 and 7 with 1off M10 x 240mm bolt, 1 off M10 Galv nut and 2 off M10 Galv washers supplied, passing the bolt through the beam then the spacer block and posts, with a washer under the bolt head as well as the nut. Figure 13. Rope Anchor Bracket at post 7. When the lap at post 7 is assembled, it is imperative to use 8 off M16 x 30 dome head double tear drop bolts supplied in the fastener kit with the dome heads on the outside of the beam, use 1 off M16 Galv washer and 1 off M16 Galv nut per bolt on the inside of the beam. Figure 14. Lap connection at post 7 Highway Care Limited Page 12 Revision 1E
Step 5 Hang Xtension 110 Beams 1 & 2 and fit Shear Bolts. Note: To assist with onsite installation, beams 1 & 2 may be delivered pre-assembled. I.e. The slider weldment and angle bar will be pre-fitted to beam 2, the slider panel pre-fitted to beam 1 and the 2 beams assembled together. Figure 15. If the beams are pre-assembled as above, lay the assembly on the floor as shown in figure 15, slide beam 2 through the slider panel until the angle bar is touching the slider panel. Figure 16. Figure 15. Assembly as delivered Figure 16. Beams slid open ready to fit. Bolt beam 2 to posts 4 and 5 with 1off M10 x 240mm bolt, 1 off M10 Galv nut and 2 off M10 Galv washers supplied, passing the bolt through the beam then the spacer block and posts, with a washer under the bolt head as well as the nut. If beams 1 & 2 are pre-assembled, also attach beam 1 to post 2 at this time in the same manner. The beams are not connected to post 3 on either the single sided or double sided terminals Figure 17. Bolted at post 4. Highway Care Limited Page 13 Revision 1E
Lap beam 2 over the connection beam at post 5 with the 8 off special shear bolts (yellow head) supplied. With the yellow head on the outside face of beam and the washer and nut on the inside. (Figure 18). The SHEAR BOLTS are to be tightened no more than 20Nm. IMPORTANT NOTE: DO NOT USE ANY ALTERNATIVE FASTENERS FOR THIS LAP AT POST 5. Figure 18. Yellow headed shear bolts at lap joint on post 5 If Beams 1 and 2 were pre-assembled go to step 8. Highway Care Limited Page 14 Revision 1E
Step 6 Attach Slider Weldment to Xtension 110 Beam 2 The Xtension beams have slotted holes at one end and tear drop holes at the other, the tear drop holes should go at the end furthest away from the impact head. Bolt the slider weldment to the rear face of beam 2 at post 3 (Figures 19 & 20). Use 4 off M16 x 30 dome head double tear drop bolts supplied in the fastener kit with the dome heads on the outside of the beam, use 1 off M16 Galv washer and 1 off M16 Galv nut per bolt on the inside of the beam. The holes for attaching the angle bar should be closest to the impact head. The angle bar needs to be removed after fitting to allow the slider panel to fit. See figure 20 for orientation of angle bar and slider weldment. NOTE: These fasteners need to be tightened at this point. Figure 19. Slider weldment at post 3 Figure 20. Slider weldment at post 3 Highway Care Limited Page 15 Revision 1E
Step 7 Assemble Slider Panel onto Xtension 110 Beam 1 Start by sitting Xtension 110 beam 1 on a spacer block or post so that it is raised off the ground. Fit the slider panel onto the outside of the beam at the end of the beam with tear drop holes at post 3 location, with the shaped and reinforced end of Slider Panel at the end of the beam as shown. Attach using 4 M16x 30 dome head single tear drop bolts, pushing the bolt through from the inside of the slider to the outside so that the nut is on the traffic face. (Figure 21) Use 1 off M16 Galv washer and 1off Galv nut on the outside for each bolt. Use a podger bar to assist with lining up lap holes, and to make sure that the slider panel and W beam mesh together tightly. These fasteners need to be tightened at this time. Figure 21. Sit beam 1 so it is raised off the ground. Align holes with podger bar. Note: nuts are on the traffic face. Highway Care Limited Page 16 Revision 1E
Step 8 Hang Xtension 110 Beam 1 Lift the assembled beam 1 and slider panel and push the slider panel over Beam 2 and the slider weldment (Figure 22). Overlap the beams so the centre of beam 1 fits to post 2. If there are any difficulties putting beams together, there are 2 wedges that can be removed to facilitate fitment, but must be replaced afterwards. Beam 1 is fixed to post 2 with 1 off M10 x 240mm bolt, 1 off M10 Galv nut and 2 off M10 Galv washers supplied, passing the bolt through the beam then the spacer block and post, with a washer under the head as well as the nut. Re attach the angle bar to the slider weldment on the backside of the beam at post 3 with the angled face towards the rear of the system (Figure 23). Figure 22. Push slider panel over beam 2. Figure 23. Attach the angle bar to slider weldment with the flat outside face towards post 3. Highway Care Limited Page 17 Revision 1E
Step 9 Attach the Impact Head Place impact head on outside of beam 1 and use 8 off M16 x 30 dome head double tear drop bolts supplied in the fastener kit with the dome heads on the inside of the beam, use 1 off M16 Galv washer and 1 off M16 Galv nut per bolt on the outside of the beam. These fasteners must be installed with the dome head to the inside of the W-Beam and the nuts and washers on the outside (traffic face). (Figure 24) Bolt the head and beam to post 1 using the supplied M16 x 50mm hex head bolt. Use the M16 square washer under the nut covering the notch in post 1 and the round washer under the head on the outside of the beam (Figure 25). Figure 24. Attach impact head to beam 1. Figure 25. Bolt the head and beam to post 1 with a square washer. Highway Care Limited Page 18 Revision 1E
Step 10 Place the Ropes Before installing the Xtension ropes, make sure the steel tube is in the correct location. Feed the ropes under the steel strap on the ground strut (Figure 26) and fit the crimped ferrule/threaded ends through the holes at the top of the anchor strut and ground anchor. Place a nut and washer on the end of each rope, only tighten the nut until a minimal amount of thread is showing passed the nut. Figure 27. Note: layout the ropes so that they will not recoil out of the safe working area. Figure 26. Push ropes under steel strap on ground strut. Figure 27. Ropes fitted through the ground anchor. Highway Care Limited Page 19 Revision 1E
Step 11 Installing the Ropes Take the rope nearest the traffic face, pick up the free crimped ferrule/ threaded end and pass through the bottom hole of the head, through the friction plate and out through the rear of the impact head. Now thread the rope down the rear of the beam past the spacer blocks and through the slider panel. Fit the rope ferrule/threaded end through the bottom anchor bracket at post 7. Fit a nut to the end of the ferrule. Repeat this process with the other rope but push it through the top hole of the impact head and thread it along the beam to the top rope anchor bracket at post 7. There may be excess slack in the lower rope at this stage, remove some of the slack by tightening the rope at the ground anchor. Figure 27. Do not tighten ropes at this stage (or the Friction Plate will not turn) Figure 28. Pass the ropes through the holes in the impact head. Figure 29. Ropes in rope anchor bracket at post 7. Highway Care Limited Page 20 Revision 1E
Step 12 Turning the Friction Plate Put a crow bar through the hole at the top of the friction plate (Figure 30) and turn it a quarter turn towards the final position, do not try to yank or tug the crow bar keep applying constant pressure while some one else gradually tightens up the four bolts in turn as the plate turns. Do not attempt to turn the friction plate with the bolts, or tighten the bolts with an impact gun, as this may strip the threads. Finally, tighten the 4No. M20 x 75mm bolts on the side of the impact head to lock the friction plate in the final position, which is at least in excess of 90 and up to the stops in the impact head. (Figure 31). Figure 32 shows the friction plate before turning and Figure 30. Use crow bar to turn friction plate. Figure 31. Use socket to lock bar in the turned position. Figure 32. Before turning friction plate Figure 33. After turning friction plate and tightening locking bolts Highway Care Limited Page 21 Revision 1E
Step 13 Tightening the Ropes Any slack in the ropes in front of the impact head can be removed by tightening the nuts at the ground anchor. Any slack behind the impact head should be removed using the nuts fitted to the ropes at post 7. Tighten the ropes until there is no excessive sagging. There is no torque requirement for the ropes. (Figure 34) Figure 34. Tighten ropes until there is no excessive sagging. Step 14 Installing the Xtension Double Sided 110 P4 Terminal components. Note: If installing a Xtension Single sided 110 P4 Terminal go to straight to step 17. Follow steps 4 to 8 above to the rear of the system to create the second side of the terminal. When bolting Beam 1 to Post 2 a Square Washer MUST be used at the notch in the post (Fig 35), this is then followed by the round washer and nut as Normal. (Fig 36) Figure 35 Figure 36 Highway Care Limited Page 22 Revision 1E
Step 15 Installing the Xtension 110 Double Sided Head. The Xtension Double Sided Head laps on the outside of Beam 1 and simply slides into the box section on the rear of the Xtension Head. It is locked into place using the Xtension Double Sided Head Pin (Figure 37), which is passed down through the two heads and secured at the bottom with an M6 x 35 bolt assembly (Figure 38). The heads are also secured together by 2 No. M6 x 35 bolt assemblies that clamp the return edges of the heads together (Figure 39). Occasionally the holes that these bolts go through become blocked during the galvanisation process if necessary this can be drilled out using a 7mm drill bit. Using 8 off M16 x 30 dome head double tear drop bolts supplied connect the head to beam 1 with the dome heads on the inside of the beam and the head lapped outside of beam 1. Figure 37 Figure 38 Figure 39 Step 16 Tighten the system bolts. Once the system has been fully build, tighten all the loose fasteners to the required torque settings (See appendix). Do not over tighten the yellow shear bolts. Highway Care Limited Page 23 Revision 1E
Step 17 Installing Plastic Nut Protectors. For aesthetics all the M16 Fasteners on the system that have the nuts and washers on the traffic face should be covered by the plastic nut protectors, (these are fitted for aesthetic reasons only and have no affect on system performance). These plastic caps need to be screwed on to the protruding fastener thread rather than pushed over the thread, by gently turning them clockwise onto the thread (Figure 40 & 41),. Figure 40 Figure 41 Highway Care Limited Page 24 Revision 1E
Step 18 Installing the Slider Washer. Place the M20 x 50 bolt with rounded end in the back of the Slider Panel, and nip up to the beam. Introduce the slider washer into the gap created note the orientation, Plastic face without the cut out touching the beam (Figure 42), slacken off the M20 bolt and tap the slider washer into the gap until it is flush with the slider assembly (Figure 43). Tighten the M20 bolt so that it secures the slider washer against the back of the beam. Figure 42. Fit the slider washer Figure 43. Tap slider washer into position Step 19 Installing the Xtension 110 Single & double Sided Warp style Nose covers. If required the yellow and black chevron stickers should be applied to the plastic nose before installation, the position and orientation of these depends on the site requirements, examples can be seen on Dwg no. XT-DE-004. The plastic nose for the Xtension 110 Double Sided System is simply wrapped around and tucked under the outer return edges of the two heads and bolted to them using the 4 No. M8 bolt assemblies (Figure 44a, 44b, 44c & 43d). Figure 43a Figure 43b Figure 43c Figure 43d Highway Care Limited Page 25 Revision 1E
Step 20 Attach Single Sided Plastic Nosing If fitting the Pre-moulded yellow or grey nose covers, first remove the 2 off nuts and washers on the ends of the ropes at the end of the ground strut. Fit the two off rope ferrules through the 2 outer holes in the Nosing unit, and place the nose over the top of the extension head. Re-fit the 2 off washers and nuts to the end of the rope ferrules. Thread the tether through the extension head and through the 2 off holes in the Nose. Join the 2 ends of the tether together using the 2 off tether clips supplied. (Figure 44). Figure 44. Attach the Single sided plastic Nose cover Highway Care Limited Page 26 Revision 1E

Xtension Inspection & Maintenance Periodic drive-by when inspecting barriers. Check for damage or detached / missing primary components. Walk-up It is recommended that every 2 years you check torque on all fasteners, clear debris from around system and any accumulated solid hazards within the lateral displacement zone, check for and repair any areas of abnormal corrosion ascertain cause (e.g. localised flooding or unreported chemical spills) and take the necessary steps to prevent re-occurrence Galvanized coatings can be repaired by the removal of any rust from the steel and the application of a 150 micron coat of high (>89%) zinc solids paint. This procedure complies with EN ISO 1461, 1999 clause 6.3. Components that are severely corroded must be replaced. Highway Care Limited Page 28 Revision 1E
