R310

 

n Unique new design for safe controllable slewing action and 360 degree rotation on virtually every lift and platform unit currently available.

n Quick fit, easy self-assembly. Simple bolt-on procedure means no skilled installers or additional machining.

n Fewer moving parts provide notably uprated reliability and reduced maintenance.

n Eliminates the need for complex worm and gearbox mechanisms - even in the heaviest duty applications.

n Smooth boom rotation. Large tooth contact for minimum wear.

n Three different sizes to suit all standard hydraulic motor drives to provide the perfect match to your unit.
