- Mar 26, 2018 -

1. Every class should check whether the safety limiters such as torque limiter, lift limiter, height limiter and amplitude limiter are in good condition and the bolts are tight. The torque and weight limit can be checked by hand switch to check the height limit. The position of the lifting hook to the upper limit position should be able to stop automatically.
2. Each half of the month should deal with a torque limiter and lifting capacity limiter to carry out a lifting test to check whether the accuracy of the two safety devices meets the requirements. If it is found that overloading should be adjusted immediately, check the adjustment method.
