HHXG Chain electric hoist drive should comply with the safety rules for certain
HHXG Chain electric hoist powered lifting mechanism and operation of institutions shall be set up brake.
Lifting mechanism after the accident may cause serious danger or loss of HHXG Chain electric hoist, its each driving system must be set up two sets of independent working brake (also known as brake).
Using the HHXG Chain electric hoist as the hoisting mechanism hoisting molten metal, the brake shall be set up in accordance with the following requirements:
A. when the rated lifting weight is greater than 5T, HHXG Chain electric hoist in addition to set up a working brake, you must also set up a safety brake, safety brake set in the HHXG Chain electric hoist low level, when the working brake failure or transmission parts break, can reliably hold the rated load;
B. when the rated lifting weight less than or equal to 5T, HHXG Chain electric hoist in addition to set working brakes, also should set up safety brake at low level, or HHXG Chain electric hoist should be designed according to 1.5 times the rated lifting weight, or the use of units selected crane rated lifting weight is 1.5 times the maximum weight, maximum weight and with weight sign explicitly allowed.
