Quad ring for Grove 2035

The quad ring, identified by part number 1900887, is an elastomer seal featuring a four-lobed cross-section. This geometry is engineered to provide an effective seal in hydraulic and pneumatic systems, functioning in both static and dynamic environments. By utilizing four lobes, the seal distributes pressure across its contact surface, which helps manage friction and resist extrusion during operation. It is intended for integration into hydraulic assemblies such as boom cylinders, outriggers, steering systems, and braking circuits within heavy machinery.

This component is compatible with Grove 2035, GMK 2035, and GMK-2035-35TON all-terrain cranes. It serves as a critical sealing element in these machines, where hydraulic pressure and mechanical movement are constant. The design of the quad ring helps prevent the twisting or rolling often associated with standard O-rings when subjected to dynamic loads.

In hydraulic systems, seals of this type are used to contain pressurized fluid and prevent leakage between internal components. By maintaining a consistent seal, the quad ring supports the pressure requirements necessary for the controlled movement of crane booms and stabilizers. Proper installation of these seals ensures that hydraulic circuits maintain the necessary pressure for safe and efficient crane operation.
