Product features and advantages
RIMA Hydraulic Rotator is purpose-built for stone grapples and timber grapples, engineered to deliver stable rotation, reliable load handling, and long service life in demanding environments such as forestry operations, timber yards, quarries, and construction sites. Its ability to perform continuous 360-degree rotation in both directions enables precise positioning, smooth manipulation, and efficient handling of logs, stones, and irregularly shaped materials. This enhances operator control, reduces cycle time, and supports safer, more accurate material movement.
The rotator high-volume, three-stator internal design is a key contributor to its performance. Combined with a large number of wings, it delivers improved hydraulic efficiency by ensuring smooth pressure distribution and reducing internal loss during rotation. This allows the equipment to maintain consistent performance even when subjected to heavy, continuous-duty workloads.
To handle complex stress conditions, the RIMA rotator integrates multiple bearing systems. Heavy axial loads generated when lifting or gripping materials are supported by a durable roller bearing. Needle bearings in the upper cover absorb negative axial forces that often occur during reversing or impact situations. Slide bearings positioned in both the upper and lower covers manage radial forces, ensuring stable rotation even when the grapple encounters uneven or shifting loads.
Longevity and reliability are further enhanced with a triple-seal solution in the lower cover. This sealing system protects internal components from contamination, maintains lubrication, and minimizes leakage—crucial for environments where dust, wood debris, and stone particles are common. As a result, the rotator requires less maintenance and offers a prolonged service lifespan.
Flexible oil connection options, located either at the bottom or side of the flange, simplify installation across various grapple and crane configurations. Finally, a two-component industrial coating offers superior resistance to corrosion and wear, ensuring the rotator maintains performance and appearance even under harsh outdoor conditions.
