Precautions
 1.Before the lifting must check whether the parts is normal.
 2.When using base shall be flat, avoid skew, forbid to use overload, such as use of multiple machines for the goods of over weight.
 3.Rising: lift rocker, will at the bottom of lift chain to the horizontal position, the rocker lever is inserted into the hole to do reciprocating movement up and down, the weight that rise. Rocker arm up or down to hear the pawl and rack contact Lota sound as normal.(decline when the same)
 4.Decline: lifting rocker, lifting spanner back to the home position, up and down reciprocating a rocker, which gradually declined.
 5.Fall: lifting spanner in the down position, use the mother refers to the lifting handle part forced by force, lift rocker, rack that fall. Fall are not  free to use ,only for the no-load rapid decline.

Maintenance:
 1.keep the essence clean, Note the friction between the friction parts, and often filling lubricating oil.
 2.One should not be arbitrarily tossing impact so as not to damage the parts.
 3.During use, Users need to check regularly according to the situation.
 4.If found mechanical damage, it should be replaced promptly to avoid accidents.
 Deliberately excluded methods:
 During use, such as the case of the rack to rise or fall is difficult. Through the spring assembly intermediate the nut to trace condition, rise was blocked down regulation, drops blocked up regulation, generally regulates the amplitude of 1mm, 2mm maximum adjustable.

Use
 1. Improve - track jack should be smoothly completed, with a length of 1.5 m steel steel rod inserted into the rocker arm hole, up and down reciprocating throw to the need of hoisting heposition.
 2. Slow down - turn slowly drop control handle up to brake position will lever up and down throw, every reciprocating or drop a tooth.
 3. Drops - pull lever, with leverage vertical impact downhill baseboard end surface, can be a down to the starting

Railway equipment mechanical jack track lifting jack with lever sockets method of use :
 1,Lifting 
 Railway track jack should be placed properly and  smoothly, insert the control hole with a 1.5 meter length steel rod, reciprocating wrench up and down until reach the requirement lifting height.
 
 2, Slowly Descending
 The track jack can be lowered tooth by tooth by wrencing the steel rod up and down while the slowly descending control handle pulled to the brake position .
 
 3, Rapid Descending 
 The track jack can be descended to the start position by perpendicular impacting the rapid descending foot pedal.
 
 4, Sliping 
 The sliding parts need to be regular lubrication, timely replacement of damaged parts.

One, Applicable scope
 Applicable 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.

TWO. the main technical parameters
 1, rated jacking force: 150 kn
 2, rated hook lift force: 78 kn
 3, hoisting lift: >=270 mm
 4, track efficiency: 127 mm/time
 5, initial height:50 mm
 6, lever (Jimmy) length (user own) : 1.5  m
 7, full load lifting maximum operating force: 1920 n
 8, outlook size: (LWH) 420 x 165 x 522  mm
 9, machine weight: <=25 kg 

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.
