Self-lock Slewing Bearing Gearbox With Hydraulic Motor For Mobile Harbor Cranes
Product Description
Slewing drive or slewing ring can be treated as a gearbox because the core components are the slewing bearing and worm shaft. It also consists of auxiliary components such as seals, housing, and motor. The motor is usually DC planetary gear motor, AC gear motor or hydraulic motor. Hydraulic motor is mainly used in the construction machinery as a power drive system. Slewing gearbox can readily withstand the axial and radial forces.
Feature
Slewing drive gearbox has reverse self-locking characteristic which greatly enhances the stability of the system and increase safety factor. Compared to the traditional swing products, slewing drive gearbox is easy to install, easy to maintain, and saves considerable installation space.
The slewing drive gearbox adopts hourglass worm technology which provides more tooth contact, thus higher torque.
Slewing gear and raceway harden processing technology to increase the slewing drive's field life.
The slewing drive gearbox is fully enclosed which could protect the drive from various environment conditions such as dust, water, sand etc.

Applications
Spider-mounted platform application
Spider-type high-rise car is mainly in the unmarked wheel type, unmarked rubber track type two walking methods.
The typical structure design
1, leg mechanism design High-altitude work vehicle has different types of legs, to level and ensure the stability of the whole vehicle work role, requiring strong and reliable, easy to operate.
2, leg span determination High-altitude work vehicle legs are generally set back and forth, and extend to both sides, leg support point vertical direction of the position selection to be appropriate, its principle is that the operating platform in the calibration load and the most (large) operating range, the stability of the vehicle to meet the requirements.
