WGR Rotation Drives
The WGR Rotation Drives consist of a worm shaft and gearing system with an integral pinion shaft, which will engage with any matching spur gear slewing ring to effect rotation. Both Metric and US spur gears can be supplied.
Two basic sizes have been developed and found successful application in the mobile crane industry, and simple materials handling devices.
|Size||Nominal output torque||Ratio||Weight|
|900 Nm||30:1||23 kg|
|2823 Nm||44:1||52 kg|
- As the output is an integral pinion-shaft, matched to a specific slew ring gear, these units are only imported to order
- All subject to factory verification of suitability
- Maximum output speed 16 rpm
- Available in left or right hand motor drive side configuration
The dimension plans below indicate the basic dimensions of the WGR Rotation drives. Final part references will be discussed with clients as required.

Part numbering system
The final part number is dependent on input shaft size and required output gear. e.g.
|Rotation drive||Size||Reduction ratio||Input shaft||Hex head non drive side||Right hand motor||Pinion size|
Input shaft options
The standard units are generally imported with 25mm input shaft for standard hydraulic motors. ø12mm, ø14mm, ø16mm, ø20mm and a 6B Spline are optional
