2, rated hook lift force: 78 kn 
3, hoisting lift: >=270 mm 

Applicable scope
SCQ - 200 type 20T track machine, applicable YuXiuJian railway when lifting section of track, Bridges or other heavy; Can also be applied to industrial and mining enterprises, transportation, ports, and other enterprises shipping, installation and adjustment of equipment and lifting, handling all kinds of heavy became a tool.
This machine structure is simple, lifting and reliability, simple operation, maintenance, maintenance is convenient. Hoisting lift, ascension (lifting) speed, track the working efficiency is high.

Three, the basic structure and working principle
This machine commonly known as the "single button" type track machine, namely rocker 4 press, rack and rise to a tooth. Rocker service for light, gently pull can not rise, rack.
1 frame, 2 bearing cover, 3 bolt, 4 rocker, 5 brake tooth plate, 6 roof, 7 rack, and famous brand, and spring, 10 spring shaft, 11 starting tooth board,

Four, method of use
Track (increased) operation - machine made put make rack hook tongue part in rail or weight, the crow insert rocker 4 hole, and force bobs Jimmy can put the section of track or weight by gear up to the required height.
Fast drop (discharge) operation - will raise up wrecking bar, rocker to a certain Angle is placed, starting tooth plate and top surface is from the rack and tooth surface, the starting tooth plate and pull back the tooth insert brake tooth plate and tail triangle groove, again press the crowbar, namely to realize fast drop (discharge).
Slow down - when lifting operation need to reduce after one or two tooth height, its operation is: Jimmy belt moved down and down, make brake tooth plate 5 from the rack and no load, pull back brake tooth plate 6, slowly release the crowbar make rack and the frame a tooth, then relax brake tooth plate and make its teeth into the rack and a tooth, relax Jimmy make brake tooth plate stress, the starting tooth plate don't force, and then gently lift crowbar, pull open starting tooth plate so that the tooth into the rack and a tooth. In this way, it is finished up weight drop a tooth height operation. By analogy, namely the realization by tooth slow down.

Five, use the matters needing attention
1, track the way before operation, should check for failure or damage, no-load operation is agile.
2, Jimmy suggest using steel pipe production, the size of outside diameter φ and ~ and mm, wall thickness 4 ~ 5 mm, length of 1.5 m, end a little taper.
3, slow down, the operator should stand in the side of the crowbar, open tooth plate hand don't stretch line is too close, to prevent scratches.
4, track operation in case of emergency, should namely fast drop operation, and out of track machine.

Six, platoon drop fault and maintenance
1, track machine lifting dumb, should check the rotating or sliding parts ever is rust or stolen goods, if any, should be clean, and add lubricating oil.
2, lifting operation, such as tooth plate "eat tooth" is not normal, should check spring and ever jump out (not pin tooth plate), found that jump out, should make its reset; Such as spring fatigue stretch enough or damage, should be replaced spring 9.
3, such as tooth plate lateral shake handshandle touch off, can welding.
4, frame 1 top square opening front such as wear serious influence and lifting operation, should be replaced frame.
5, use for a long time, the rack and brake tooth plate 5 and starting tooth plate and tooth part wear serious influence use, should be replaced.

Seven, maintenance
1, track machine long not buy, check the rotation before use, sliding parts have rust, no-load operation is normal or not, otherwise, should be cleaning, lubricating.
2, should avoid to throw rejection, lest meet the bad parts.
3, after use, such as viscosity have sediment, dirt should be clean; Should be properly placed custody, and in the rotational parts moderate oil lubrication, don't placed outdoor be caught in the rain.
