Wiper for Terex RT780

The wiper with part number 217240 serves as a sealing component for hydraulic cylinders on Terex machinery. Its primary function is to scrape and clean dirt, dust, moisture, and other contaminants from the surface of the cylinder rod as it retracts. By preventing these particles from entering the hydraulic system, the wiper protects internal seals and maintains the integrity of the hydraulic fluid.

This component is specifically compatible with the Terex RT780 rough-terrain crane. It is installed within the hydraulic cylinder assemblies to support the operation of the boom, outriggers, and other actuators. The part is engineered to maintain constant contact with the rod surface to ensure effective cleaning during cylinder movement.

In hydraulic systems, rod wipers are standard components used to prevent external debris from contaminating the internal environment of the cylinder. Proper maintenance of these seals is necessary to avoid premature wear of internal sealing elements, rod scoring, and fluid contamination, which can lead to pressure loss or erratic cylinder performance.
