The motor is an important driving device in the vehicle-mounted crane. The operation of the motor can drive the lifting and lowering of the wire rope.
Therefore, the motor is the “heart” of the whole small davit crane. The quality of the motor is closely related to the material of the motor, so everyone must pay attention to the motor of the on-board crane when purchasing the on-board crane.
At present, there are many types of vehicle-mounted cranes on the market, and the motors of pickup truck cranes are also various.
At present, the most recognized motor is copper motor. Some unscrupulous manufacturers ostensibly say that their winch cranes use copper motors, but they are actually “selling dog meat with their heads raised”, so everyone must pay attention to this point and beware of being deceived.
Copper motors have good heat dissipation. At present, the relatively good motors on the market are divided into copper motors and copper wire motors.
Both of them refer to the stator coil of the motor as copper wire. But now there are some motors on the market whose coils are aluminum wires and then coated with a layer of copper.
The service life of such a motor will be reduced, and the motor will overheat. So be careful when purchasing.
In this regard, there is one more suggestion for those who are purchasing a thern davit crane. Be sure to choose a portable davit crane from a regular manufacturer. Don’t be greedy for cheap, and remember that “cheap is not good, and good is not cheap.”
