Why overhead crane brakes can not be reversed

  bridge gantry crane  are widely used in industrial and mining enterprises as a crane, a locomotive depot is now more than one attachment overhead crane, daily use of frequent, heavy workload. Bridge crane can work directly affects the locomotive maintenance tasks and personal and equipment safety.
      Bridge crane body heavy, a lot of inertia at run time, and the normal operation of  steel crane  brakes immediately when inverted, will make the entire run organization with great torque, to the detriment transmission. Severe broken drive shaft, also make the body skew distortion; reverse brakes also make the gear linkage system occurred violent impact, damage gear, resulting in equipment accidents; reverse brakes also make electric power machines produce a very large torque and strong currents, severe motor will burn out.
Reverse brakes also make the air caused by hanging objects swing hanging objects fall occurred. So, at work, in addition to the event in order to avoid the special danger of an accident outside, does not allow reverse brakes.
      With the fast development of electronic technology, inverter performance and reliability have been greatly improved, as the  overhead bridge crane  drive control system provides favorable conditions.
