A rotator for every job

Want to increase your excavator’s productivity by up to 30 per cent?

Which rotator is right for you? It all depends what kind of job you’re doing and what kind of machine and grapple you’re operating. A rotator works hand in hand with a grapple to achieve maximum performance.

Depending on the application, a rigid-mount rotator may be the best option, and Intermercato Grapples has two popular types – worm-drive rotators and RMR rotators. You can be sure all the rotators Intermercato Grapples recommends are high quality and fit for purpose.

Worm-drive rotators

Intermercato Grapples’ worm-drive rotators are a popular choice to complement any Intermercato grapple.

A worm-drive rotator allows spinning 360 degrees clockwise or anticlockwise endlessly. An Intermercato Grapples worm drive has a specially designed low ratio, making it great for use with excavators. The worm is powered by a hydraulic motor which turns a bevel gear around a worm gear.

It’s that simple!

The benefit of the worm-drive type of rigid-mount rotator is it will hold a load steady at any angle. For example, if a branch is held in the air with the excavator and it’s cut by a chainsaw, the branch will stay in position and not move once it is cut. It allows more control, but is slightly slower than other options. However, if overloaded, the worm will creep backwards to take pressure off the teeth.

The worm drive-style is great for putting in standing posts, feeding chippers, or mounting on a chainsaw.

RMR rotators

The RMR rotators from Intermercato Grapples are also extremely popular.

The RMR-type of rigid mount rotator uses gerotor technology to create a compact, high side-load-withstanding rotator.

The axial and radial loading is due to the tapered roller bearing of the dual mounted, forged drive shaft.

The gerotor design allows a much faster operation than the worm drive. The only downside is it doesn’t hold the load steady. With a long load lifted to the left or right of the centre of gravity, the RMR will rotate freely until it stops moving. It’s an excellent choice for sorting grabs and feeding chippers.
