Overall hoist can be divided into:

 series with mine hoist brake
 lifting clamp speed
,  series of mechanical speed hoist series with mine hoist brake drum wrapped with rope or chain to enhance or hauling heavy loads of small light lifting equipment. Hoist can be used alone, can also be used as components of lifting machinery, road construction and mine hoist, etc., because of simple operation, roping large, convenient and widely displaced.  series with mine hoist brake Use: suitable for all kinds of small and medium sized mine shaft tilt Jining Coal roadway transportation of materials, for the low yield of small mines, but also for the major upgrade of equipment is mainly used in coal, metal mining, non-metallic mineral inclined roadway and shafts for lifting Inoue, issued by the material, the lifting device can also be used as an aid used in other places.  series with electric wire rope hoist  brake characteristics: highly versatile, compact structure, small size, light weight, major and easy to use transfer is widely used in construction, water conservancy, forestry, mining, port and other material movements or flat mop, but also for modern electronically controlled automatic equipment operating line.  series with brake mine hoist the main models: Model explanation: J: winch category; T hoist; B: Explosion;
0.8 * 0.6W: 0.8 米 * drum roll width 0.6 m diameter -0.8 * 0.6W: motor power 22KW-0.6 * 0.5W: motor power 15KW-1.0 * 0.8W: motor power 45KW

lift hoist Introduction

Lift hoist into the following mobile, fixed, wall-mounted, towed, self-propelled, vehicle-mounted,portable electric hoist
  retractable total of seven categories.During rotation operation of the lift platform must be played before the next boom lifting height rotating, slowly rotating, and cut arm and a platform from a variety of equipment meets safety requirements.
Lift hoist should be defined as: Lift hoist up and down in the vertical channel to carry people or cargo lifting platform or lifting machinery or apparatus semi-closed platforms.electric wire rope hoist By the platform as a whole as well as equipment, motors, cables, and other auxiliary equipment operated by the composition.

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.
CD type wire rope electric hoist
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;
