9 Belt Squaring REGARDLESS OF THE TYPE OF SPLICE Extends life of Belt, Fastener and Conveyor Components Evenly Distributes the Tension Load Across the Width of the Splice Allows the Belt to Track Correctly Quick and Easy Job that Offers Improved Performance and Extended Life

18 Installation Tips - Belt Squaring/Cutting Extends lives of the belt, fasteners and conveyor components Evenly distributes the tension load across the width of the splice Helps the belt track correctly Do not square off of the edge of the belt Find the center line Do not use a utility knife.

19 Installation Tips Belt Skiving

20 Installation Tips Belt Skiving

21 Installation Tips Belt Skiving Use a tool designed for skiving, not a knife Whenever possible remove enough cover to get the fastener below the top of the belt Place the fasteners as close to the carcass as possible Leave approx. 1/16 of cover over the carcass

22 Fastener Selection Belt Tension Rating Actual Operating Tension PIW Pounds per Inch of Width kn/m kilo newtons per meter Rated Tension of the Belt

23 Fastener Selection Belt Thickness At the point of installation After skiving

24 Fastener Selection Minimum Pulley Diameter Diameter of smallest pulley around which the belt travels at least 90 No matter what name you have assigned to it 25% larger diameter required if it is a winged pulley

27 Bolt Fastener Installation Tips Use an Impact Tool, Not a Drill! Develops six times the torque Will not twist your wrist Tools will last longer 5552 Quick Change Chuck

28 Bolt Fastener Installation Tips Hold Impact Tool straight up and down Use Lock Tape Do not tighten nuts completely on first pass Tighten nuts from the outside in Tighten nuts until the belt puckers

31 Bolt Solid Plate Installation Tips Fully Use the Templet

32 Bolt Solid Plate Installation Tips Fully Use the Templet

33 Bolt Solid Plate Installation Tips Fully Use the Templet

34 Bolt Solid Plate Installation Tips Use a purpose manufactured Lock Tape! Lock Tape is not an option! Lock Tape is not intended to prevent seepage!

35 Bolt Solid Plate Installation Tips The Lock Tape does not prevent seepage!

36 Bolt Solid Plate Installation Tips The use of Lock Tape will result in a smooth splice!

37 Bolt Solid Plate Installation Tips Don t skip a step, final set the plates Sets the teeth into the carcass Can flatten the top plates Properly installed fasteners reduce downtime!

38 Bolt Solid Review Lock Out Tag Out Square and cut the belt properly Determine the appropriate fastener Use the template to align the bolts when installing the second belt end Use the Lock Tape

39 Bolt Solid Review Use an impact tool, not a drill Final set the plates properly Use short strokes when using bolt breakers Observe the splice and belt while it is running

48 Elevator Splice Available from many sources Accepted in the industry The weakest method of splicing a belt

49 Elevator Splice The weakest method of splicing a belt Minimum pulley diameter Largest fastener bends belt through a 75mm radius to 90 = 6 dia. Smallest belt requirement is 12 inches at 40%/60% of PIW Squaring the belt Torque required for installation 75 foot-pounds under 600 PIW 100 foot-pounds over 600 PIW
