The boom seal kit 215578 serves as a comprehensive set of hydraulic seals for the extension cylinders of the boom assembly. By replacing the internal sealing elements, this kit restores the hermetic integrity of the cylinder, which is required to maintain hydraulic pressure during the extension and retraction of the boom sections. It prevents external fluid leaks and blocks the ingress of contaminants into the hydraulic system.
This component is compatible with the Terex RT 230 rough-terrain crane model. The kit includes a selection of piston seals, rod seals, wiper seals, wear rings, and O-rings tailored to the specific dimensions of the cylinder assembly. These components are used to rebuild the cylinder when internal bypass or external leakage is detected during routine maintenance, ensuring the machine maintains its rated lifting capacity and operational control.
In hydraulic systems, seal kits are used to manage the interface between moving parts within a cylinder. The seals maintain the pressure differential across the piston and rod, which allows the hydraulic fluid to actuate the boom. Regular replacement of these seals during cylinder service helps prevent pressure loss and ensures smooth, predictable movement of the crane boom during lifting operations.
