In order to prevent overload gantry crane rope, should take the following measures

In order to prevent overload gantry crane rope, should take the following measures:


1) selection of the safety factor indeed, seek to reduce static load other than the impact load on the rope.hoist gantry crane Such as bending load can be increased to reduce the diameter of the pulley and the drum, dynamic load can improve the operation of the crane driver level, crane performance improvements to reduce frictional resistance can adjust the shape of the pulley groove and supplemental lubricant to reduce so .

2) grid compliance with safety procedures, to eliminate artificial overload phenomenon.

3) installed on the gantry crane load indicator or overload limiter, or alarm, eliminate overload.

The main gantry  steel crane  safety device which?

The main gantry crane safety devices are: tower crane: Starting weight limiter, load moment limiter, lifting height limiter, amplitude limiter, walking limiter hook safety device. Anti-rope hopping devices; construction elevator: Security, limit switches,bridge gantry crane anti-Slack-wire switch and door interlock safety device, etc..
