Production Workshop Bridge Crane Notice 2

Continuing from the previous article "Production Workshop Bridge Crane Notice 1", in addition to paying attention to the safe use of hooks, wire ropes, drums and wire rope pressure plates, workshop bridge cranes also need to pay attention to reducer gears, brakes, wheels and tracks and Safety accessories and other four aspects that cause mechanical failure:

4. Reducer gear

(1) Failure analysis

The reducer is an important transmission part of the bridge crane. The torque is transmitted through the meshing of the gears, and the high-speed operation of the motor is adjusted to the required speed. Mechanical failures such as wear and tooth surface wear, the causes of gear failures are as follows:

① Fatigue fracture caused by short-term overload or impact load, repeated bending;

(2) Preventive measures

① The crane cannot be used for loading, and the start and brake should be slow and stable. It is forbidden to reverse the car suddenly under non-specific circumstances;

5. Brake

(1) Failure analysis

② The brake pads are severe or a large piece falls off, or the long-stroke electromagnet is stuck, the main spring fails, or the main parts of the brake are damaged;

(2) Preventive measures

6. Wheels and tracks

7. Safety accessories
