Plated springs to resist corrosion. Precision machining throughout. Large base insures a firm foundation. Supports full rated capacity on the toe or the cap. Steel lever bars sold separately. MCHNICL 17 9 is used to lift a CNC machine for installation. Five ton lifting capacity, low toe height and light weight make the models,, & universal tools. Ten ton models 17 & are used extensively by structural movers, riggers & maintenance crews. Ton Ratchet Jacks These units are all mechanically identical and vary only in stroke and height. Ton Ratchet Jacks The 17 and incorporate a ductile iron housing for maximum durability. The, which is identical to the except for an aluminum housing, is the ideal choice when portability is important. These jacks are often selected for lifts of tons or less because of their low handle effort. Ratchet Jacks 1 Utility Pole Jack Light weight aluminum alloy housing is used for pole lining maintenance by telephone, light and power, and railroad companies.

9 MCHNICL SPRDR JCK The model Spreader Jack Is used when working in close quarters. The Spreader Jack has a closed height of only, with 1 stroke for adjustments, yet it can support tons. The serrated cap rotates to prevent twist out, but does not pivot. The Spreader Jack may also be used as a planer jack. 1 1/ The Spreader Jack can easily be extended by fitting a 1 diameter pipe in the base well and a 1/ diameter pipe in the cap well. PLNR Four different models are available, with capacities ranging from to tons. They are used in leveling work on plane beds, millers and other machinery. Screw's operation provides infinite height adjustments for exact leveling. The side-locking screw keeps the jack extended and prevents lowering due to vibration. The ball and socket cap swivels to center load forces. The notched base fastens easily to machine beds. 1P P P P Sustaining Cap. Minimum / / 1/ 7 1/ Operable Rise 1 1/ cross Flats / 1/ /
