SE14 High Torque Hydraulic Slew Bearing With Worm Gear Design For
Cranes
Hydraulic Slew Bearing
The slewing drive device of hydraulic excavator mainly includes two
types of components: motor and reducer. Among them, the motor is
mainly a hydraulic motor. The main characteristics of this motor
are high speed and low torque. Under the action of the motor,
deceleration should also be used. Only by decelerating the slewing
drive can the slewing drive activity be initiated.

Applications
The garden pruning car
It is mainly used for large-scale pruning projects such as
highways, municipal gardens, urban greening, tea garden picking,
etc. It can be adjusted into flat, trapezoidal, tower-shaped and
other switches for pruning, and the pruning speed is 5-10
kilometers per hour. Improve work efficiency, reduce labor or
insecurity, and enhance pruning.
Forklift spinner
A forklift spinner is a device that can be attached to forklift
tines to rotate the machine. When standard forklifts move objects
up and down, units equipped with a spinner attachment can also tilt
those objects from side to side. Like other types of forklift
attachments, spinners provide the machine with a greater range of
motion, allowing it to be used in a wide variety of applications.
360° quick turnaround for containers that need to be turned or
emptied. Widely used in food, chemical, sanitation, article
recycling, smelting and casting industries. and any occasions where
hoppers or bins need to be turned over.
