The 6 techniques to prevent electric Wire rope winch a short rope

1 Wire rope winch  and drum drum: nominal diameter and the wire rope diameter ratio shall not be less than 14; multilayer winding reel should be higher than the outer layer steel wire rope is 2 times the diameter of the wire rope should be flexible flange; strong electric winch rotating drum, drum wall should not crack or excessive wear; wire rope electric gourd drum rope end fixed device should be anti loose and self-locking function.
2 the end of the rope is fixed: wire rope electric hoist rope end fixed should be stable, reliable. The wire rope end fixed generally has 4 ways: the plate end of the rope must be firmly on the two ropes, and nut should be anti loosening device with joint; electric wire rope hoist metal pressing, joint should not crack; wedge when, should not loose, wedge sleeve should not crack; rope card, card mounted to the right direction of rope, rope clamp plate to press in force rope (not long rope, rope), and the number and distance shall conform to the requirements.

3: to ensure safe turns electric wire rope hoist operation safety, work, crane reel should be retained for at least two ring wire rope as its security laps. The method is examined: super-low electric chain hoist  the hook into the lowest (usually ground), then check the security circle number, not including the tail rope a fixed number of laps.
4 rope retaining device shall be fitted with a device to prevent: pulley wire rope, rope retaining device and pulley clearance no greater than 1/3 the diameter of the steel wire rope. Can use visual inspection method, when necessary, can be measured by a ruler or vernier caliper.
5 wire rope and pulley pulley group: mainly used to change the direction of movement of the wire rope. First check the wire rope around the order correctly, wear and lubrication between the pulley, also check each pulley and rotation. In addition, also check each pulley flange has no cracks or damage, if any, must be replaced immediately.
6.Scrap and update  wire: wire rope should be good lubrication, no friction and metal parts; there shall be no kinks, crushed, bent, broken strands, cage shape distortion, core fracture phenomenon;

Hoist tool features

1 convenient maintenance

power chain hoist Steel structure design of gourd simplifies maintenance and replacement parts, this is the advantage of gourd great.

2 operation modes

Hoist working mode is divided into single speed and double speed hoist, hanging hook or a running car manual or electric, bidirectional or multidirectional operation.

The 3 overload protection

Some high-end manual hoist for added safety additional overload protection device. This load is a kind of special protection horizontal lifting for the operator, hoist and. When the load is greater than the set value, the overload protection automatically enabled, hoist lifting will automatically stop

4 nickel surface hardening

Ni hardened chain after special treatment, do not affect the original chain properties rope blocks. Ni hardened chain has superior performance, can resist water, sea water, water and chemical substances can cause corrosion.

Electric hoist chain maintenance:

First of all, chain electric hoist gear box oil from the working up to 500 hours please check the oil quantity is enough, after third months of regular inspection lubricant, deficiencies need to refuel.
Second, the use of 15 ton electric chain hoist in outdoor, should get the rainproof equipment.
Third, often keep electric chain hoist parts dry, after operation, please leave China gourd high-temperature zone humid area, or chemical District, in order to maintain its performance.
Fourth,2.2m/min electric chain hoist maintenance, chain please oil lubrication, high dust factory please on oil, and periodically remove the chain and guide foreign body in the limit groove group, to ensure the smooth operation of the chain.
Fifth, 380v electric chain hoists long-term when not in use, should be treated against rust and cleaning and maintenance, and run up and down the 1-3 minutes to maintain its performance.
