powered with hourglass worm Slew drives with capacities of 5,000 to 200,000 ft-lbs applied to truck cranes

Slew drives are powered with hourglass worm technology for maximum gear torque and the smoothest rotation.

Typical slew drive applications include truck cranes, man lifts, utility equipment, hydraulic attachments, oil tool equipment, marine cranes, tire handlers, digger derricks and automotive lifts, but the slew drives are used in many other applications requiring load holding and rotational capability.

We offer different slew drive models with moment load capacities of 5,000 to 200,000 ft-lbs.

The standard slew drives are fitted with an open housing and single self locking hourglass worm shaft.

Once the power source input is returned to neutral, the worm shaft will lock the load into position without requiring any external braking device.

If this is not desirable for the application we offer overrunning worm shafts that will allow the load to back drive the input shaft and motor.

We also have dual input slew drives to double the torque and fully enclosed housings for industrial environments where personnel are working closely to the moving gears.

Features:

* Superior design
* Reliable performance.

* Inherently self-aligning and robust.

* Widespread use and versatility.

* The bearings are insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.

SE14A SLEWING DRIVE

Parameter

Introduction

Slewing drive is consist of slewing bearing,worm shaft,housing,bearing,motor and so on. Motor drive the worm shaft, the outer ring of slewing bearing will rotate, the outer ring output the torque through flange while the inner ring of slewing bearing is fixed in housing.

Function

Slewing drive is able to sustain more axial load, radial load and tilting moment.Turntable or frame rotate at azimuth and elevation driven by slewing drive.

Application

●For Solar:It is designed in solar tracking system and improve power generation efficiency.

●For industrial usage: Mainly used to drive two relative rotating objects in 360°.

Advantages

● Slewing drive designed with hourglass worm shaft which provides more tooth contact and higher torque.

●Service life is increased by gear and raceway harden.

●Product performance is tested and ensured product quality.

●S&G is capable of customized solution

●Types: SE,PE,ZE,S,HSE and SE-2

●ISO9001 & CE

Friendship Recommendation

Horizontal installation

It is advised to mount the slewing drives upside down on the azimuth axis in solar applications for better protection and add protection for the elevation axis.

For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.

Vertical installation

It is advised to mount the slewing drives referring to attached drawing upside in solar applications for better protection.

For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.
