Electric bridge crane trolley with small braking force

Jul 08, 2019
The electric bridge crane is mainly used for loading and unloading operations in indoor assembly workshops, prefabricated workshops, etc., with high site utilization rate, wide operating range, wide adaptability and versatility.
Electric bridge cranes usually use the wire rope electric hoist as lifting hoists. In special cases, two hoists are used on one bridge crane, so the braking performance of the hoisting trolley is very important. In the use of the electric bridge crane, when the braking force of the lifting trolley is less than the specified requirements, there are two possible reasons: one is that the nut is incorrectly adjusted, and the other is that the brake ring is seriously worn and the braking pressure of the brake spring is small.
For these two cases, only need to re-adjust the brake nut according to the requirements of the lifting trolley manual, or replace the new brake ring.
In addition to the above two reasons, other reasons are: brake surface has oil, loose brake ring, poor contact of the brake ring, motor coupling stuck, failure of brake pressure spring, etc. Need to find, adjust or replace in time.
