What is the role of the swing motor in the excavator?

The swing motor is a key part of the swing mechanism. It can convert the oil pressure provided by the main pump into mechanical energy and input it to the reduction box. The quality of its working performance will directly affect the rotation speed, driving torque, rotation parking and parking brake of the whole machine, which is the key to determining the productivity of the whole machine. High-speed swing motors are divided into two categories: swash plate type and inclined axis type quantitative piston motors.

What is the difference between a walking motor, a swing motor and a normal motor?

In fact, there is not much difference in appearance and type.

The main difference is the difference in performance. Basically, the walking motor and the swing motor require low speed and high torque. The required speed is not very high, but the output torque is relatively large to overcome the load. However, ordinary motors are not necessarily in this regard. The matching relationship between speed and torque will be comprehensively considered to ensure that the motor can meet the working requirements.

What is the role of the swing motor in the excavator?

The swing motor in the full hydraulic excavator is the key part of the swing mechanism. It can convert the oil pressure provided by the main pump into mechanical energy and input it to the reduction box. The quality of its working performance will directly affect the rotation speed, driving torque, rotation parking and parking brake of the whole machine, which is the key to determining the productivity of the whole machine. swing motors are divided into two categories: low-speed high-torque motors and high-speed swing motors.

Low-speed and high-torque motors are rarely used in modern excavator slewing mechanisms due to their large size and heavy weight, while high-speed slewing motors are small in size and light in weight, which is convenient for the reasonable layout of slewing mechanisms and can also meet different slewing speeds. and torque requirements, it is widely used.

What if the swing motor can't turn?

At present, excavators and turntables are equipped with parking brake devices. If the brake solenoid valve is faulty or its control circuit is faulty, the motor brake device cannot be turned on.

If the turntable swings the shift brake solenoid valve is broken. What are the emergency measures?

The main function of the solenoid valve is to move the 2-position 3-way valve left and right to cut off or connect the control oil circuit. We can directly connect the hose A to the connector of the hose B, and the motor can rotate without going through the solenoid valve temporarily.
