Overhead crane safety tips card Operating the Crane and Moving the Load

  Fatalities or serious injuries can occur if   overhead cranes   are not inspected and properly used. Fatalities may occur when workers are struck by a load, or pinched between the load and another object. The following are some safety tips for overhead crane operators to follow while operating the crane machine and moving the load. •Do not engage in any activity that will divert your attention. •Do not lift, lower, or transport a load with the crane or hoist until all personnel are clear of the load and the load’s path. • Verify that the load, crane and hoist will clear all obstacles before moving or rotating the load. •Do not move loads over personnel. •Do not lift, lower, or transport personnel by means of the crane, hoist, trolley, hoist hook, or load. • Slowly inch the hook into engagement with the load to eliminate wire rope slack and reduce impact loading of the crane and hoist. • Avoid unnecessary inching and quick reversals of direction. • Lift the load only a few inches to

Single Speed Electric Wire Rope Hoist

  Electric wire rope hoist is a type of electric hoists for material handling, installed on a   single beam crane,   linear curve strander beams or it can be used at the hoisting mechanism of   double beam crane , gantry crane, linear crane for material handling by industrial and mining enterprises, railways, and warehouses, etc. The lifting capacity of single speed electric wire rope hoist is 0,5 to 32 ton and the working class is M3 and M4. The main parameters of electric wire rope hoist is as follow: Product Type CD1 Lifting Capacity of High Speed Hoist 0.5~32t Lifting Height High Speed Hoist 6~50m Lifting Speed High Speed Hoist 8 m/ min Travelling speed 20,30m/min Working Class High Speed Hoist M3,M4 Ambient Temperature -25~40℃

Wire Rope Electric Hoists Inspections

  1.Wire rope electric hoist motor temperature rise is too high. First of all, check whether the  wire rope electric hoist  is overloaded. The overload causes the motor to heat up. Then check whether the motor bearing is damaged or not, and whether the motor works according to the regulations. When the motor is running, if the brake clearance is too small, will generate a large frictional force. The frictional heat also increases the additional load. 2.Wire rope electric hoist can not start after heavy objects rise to mid-air, or after parking can not re-start. First check if the system voltage is too low or the fluctuation is too large. If it is, restart it only after the voltage returns to normal. On the other hand, if it cannot be started after stopping, pay attention to whether there is a phase loss in the operation of the three-phase motor. 3.Can not stop working. The power should be cut off immediately, the wire rope electric hoist should be forcibly stopped, and the repair the c
