For heavy-duty cranes, the diameter of the clutch plate is 430mm, the specific model is Ø430x250x50, and it consists of 4 plates. Among them, Ø430 means that the diameter of the clutch plate is 430mm, 250 means that the thickness of the friction plate of each clutch is 250mm, and 50 means the position and depth of the nail hole used to locate the clutch plate.


The function of crane clutch pressure plate assembly

The crane clutch is an important part of the crane transmission system. Its main function is to realize power transmission and transmission operation. At the same time, it can also play the role of disconnecting the transmission and protecting the transmission mechanism in emergency situations. During the working process of the crane, the main motor drives the drive shaft to rotate, and the power is transmitted to the traveling mechanism and crane mechanism through the centrifugal clutch to realize walking and lifting operations.


Work principle of crane clutch pressure plate assembly

The crane clutch is a friction clutch, which is mainly composed of clutch disc, friction plate, spring, pressure plate, transmission shaft, etc. When the clutch pedal is depressed, the clutch disc is separated from the main drive shaft, and the clutch disc is connected to the auxiliary drive shaft to separate the transmission. When the pedal is released, the clutch disc reconnects with the main drive shaft and transmission will resume.

At the same time, the crane clutch also has the function of speed change. During the working process of the crane, the speed needs to be adjusted to adapt to different working situations. The clutch can achieve different output speeds by changing the transmission ratio.


Technical parameters of crane clutch

The technical parameters of the crane clutch include rated torque, rated speed, friction plate thickness, transmission ratio, etc. The rated torque is the maximum torque the clutch can withstand, and the rated speed is the maximum speed at which the clutch operates. The thickness of the friction plate is an important indicator of clutch life and performance, while the transmission ratio will affect the speed and torque output of the crane.
