2023-05-25 17:37 click:735

Clean room double girder overhead crane is a kind of lifting equipment specially used for dust-free or high-cleanliness occasions. It can avoid dust, particles, oil and other pollutants generated during the operation of the crane to ensure the cleanliness of the production environment, mainly composed of bridge frame, cart running mechanism, trolley, clean room hoist and so on. It is a special lifting equipment suitable for various clean workshop environments such as biotechnology, medical equipment, pharmaceutical production, food production, and semiconductor manufacturing.

Clean room double girder crane

The operating principle of the clean room double girder overhead crane:

  ● Transmission of the hoisting system: The power source of the hoisting mechanism is generated by the motor, and the power is transmitted to the high-speed shaft end of the reducer through the gear coupling, compensation shaft, and brake wheel coupling. After the high speed of the motor is reduced to the required number of revolutions, it is output by the low-speed shaft of the reducer, and the power is transmitted to the drum group through the inner ring gear on the drum, and then the hook is lifted and lowered through the wire rope and the pulley group, thereby Complete the purpose of lifting heavy objects.

  ● Transmission of the cart running system: the power is sent by the motor, and the power is transmitted to the high-speed shaft end of the reducer through the brake wheel coupling, compensation shaft and half-tooth coupling, and the high speed of the motor is reduced through the reducer After reaching the required number of revolutions, it is output by the low-speed shaft of the reducer, and then connected with the driving wheel shaft of the cart through the full-tooth coupling, thereby driving the rotation of the driving wheel of the cart and completing the purpose of vertically lifting heavy objects on the bridge. The driving mechanisms at both ends of the cart are the same.

  ● Transmission of the trolley running system: The trolley running system is similar to the big trolley running system, except that the trolley running system does not have a compensation shaft and a half-tooth coupling. The running system of the trolley is composed of electric motor, brake, reducer, full-tooth coupling and active wheels of the trolley. The driving wheel of the trolley is connected with the low-speed shaft of the reducer through a full-tooth coupling, which drives the rotation of the driving wheel of the trolley, and completes the purpose of lifting heavy objects laterally on the bridge.

Advantages of clean room double girder overhead crane:

  ● It can avoid dust, particles, hair and other pollutants produced by the crane during operation, and ensure the cleanliness of the production environment.

  ● Stainless steel, anti-corrosion coating, anti-static device and other materials and technologies are used to improve the wear resistance, corrosion resistance, dust resistance and safety of the crane.

  ● With honeycomb beam design, it has the characteristics of light weight, large load and strong wind resistance. In addition, the unique steel pin connection is not only firm and reliable, but also has a short assembly time.

  ● Electrical systems such as full frequency conversion control, encoder, and PLC program control can be used to realize the stability and accuracy of lifting and operation. At the same time, power supply methods such as drag chains or trolley lines can be used to avoid cable wear and loosening.
