 Overhead Crane Parts Description

1.      Overhead Crane Parts Description electrical equipment installation, maintenance, adjustment and use process, should according to the original design drawings, to ensure that the electrical equipment and various safety devices and reliable.

2.      Overhead Crane Parts Description electrical equipment generally consists of motor, brake electromagnet, control and protection electrical appliances equipment composition and so on. The safety technical requirements are as follows:

(1)   Overhead Crane Parts Description motor

Crane parts should have high mechanical strength and operation of motor overload capacity, in order to drive the cart, trolley, main clasps and deputy to work properly, and can adapt to frequent start, inversion, and braking requirements. Motor before installation must verify insulation performance, the stator insulation resistance should be up to 2 m, rotor insulation resistance should be up to 0.8 m.  During the period of using, the stator insulation resistance should be 0.5 m, the rotor insulation resistance should be up to 0.15 m.

(2)   Overhead Crane Parts Description braking electromagnet

Brake electromagnet work together with the crane motor, the magnets and released, to work and the parking brake. Electromagnet installation before use must testing insulation resistance, the resistance and the motor stator coil resistance is the same. Such as below required, must be dry boarding and inspection rear can use.

(3)   Overhead Crane Parts Description Control of electrical appliances

Crane electrical appliances mainly include the controller, the control of resistor and other electrical equipment, the main operation and control of motor function. Controller is the contact for open and close frequently produce strong spark burning, hangs, or poor contact, shall regularly check, found that the above situation in a timely manner to repair. Resistor in use should not exceed 300 ℃ temperature, resistor surface should be clean, easy to heat dissipation, these resistors should be keep straight and has a certain interval, such as found that touch each other adjustments must be timely correction.

(4)   Signal and lighting device is auxiliary the Overhead Crane Parts Description electrical equipment safety.
