Gromar 16 T forestry hydraulic rotator

What it is

The Gromar 16 T Hydraulic Rotator was developed for demanding applications, delivering robustness, reliability and high-level performance. It supports a static axial load of up to 16 tonnes and offers continuous, unlimited rotation with precise control — ideal for forestry equipment, recycling machines, cranes and other operations requiring high durability.

Built with chrome-molybdenum steels and high-durability components, it is produced in Brazil, with spare parts available for immediate delivery. Each unit is sized to the customer's application and inspected under ABNT NBR ISO 9001:2015 certification.

Typical applications

Timber extraction

Forestry cranes, harvesters and grapples — continuous rotation for positioning logs and heads.

Recycling and scrap

Handling with hydraulic grapples in intense operation, with high resistance to load and impact.

Cranes and load handling

Precise positioning of suspended loads, with smooth rotation under working pressure.

Agricultural implements

Cranes and manipulators in the field, where durability and fast parts replacement are essential.

Frequently Asked Questions

What is the load capacity of the Gromar 16 T Rotator?

The rotator supports a static axial load of up to 16 tonnes and a dynamic axial load of up to 8 tonnes. The static load is what the equipment holds while stationary; the dynamic one considers the effort in motion, with the impacts typical of operation. When sizing, what should be compared to the weight of the grapple and the handled load is the dynamic value.

What are the working torque, pressure and flow?

Rotation torque is 2,800 Nm at 250 bar, with maximum working pressure up to 300 bar and a recommended oil flow of 35 l/min. Connections are G 3/4" on the rotator and G 1/4" for the attached grapple or tool. Operating above the recommended flow increases oil heating without a proportional performance gain.

Is rotation continuous or is there a rotation limit?

Rotation is continuous and unlimited — endless 360°, in both directions, with no stop forcing the operator to unwind the rotation. This allows positioning logs, scrap or suspended loads directly, without losing cycle time on repositioning.

On which equipment can the rotator be used?

It is used on forestry cranes, harvesters and grapples in timber extraction; on hydraulic grapples for recycling and scrap, with intense operation and high impact exposure; on cranes requiring precise positioning of suspended loads; and on cranes and manipulators for agricultural implements. Each unit is sized according to the customer's application.

Are the spare parts imported?

No. The rotator is manufactured in Brazil, in chrome-molybdenum steel, with spare parts available for immediate delivery — no waiting on imports. Production is inspected under ABNT NBR ISO 9001:2015 certification. We also offer custom manufacturing and reconditioning: just tell us the working load, the grapple or tool type and the equipment.
