Roof wiper assembly for Terex RT780

The roof wiper assembly, part number 216893, manages the cleaning of the overhead glass panel in the crane cab. It functions by moving a wiper blade across the surface to clear away environmental obstructions such as moisture and dust, which is necessary for the operator to monitor load positioning and crane movements from the cab. The assembly includes the motor, linkage, arm, and blade required to maintain visibility through the roof window.

This component is specifically configured for the Terex RT780 rough-terrain crane. It integrates into the cab electrical and mechanical systems to provide consistent clearing action across the glass surface. The assembly is designed to fit the mounting points and electrical connections standard to this model of crane.

In heavy machinery, wiper systems are critical for maintaining operator situational awareness during adverse weather or dusty conditions. These assemblies typically consist of an electric motor that drives a linkage mechanism to oscillate the wiper arm. The system is engineered to function across the specific curvature and dimensions of the cab glass, ensuring that the operator retains a clear line of sight to the work area and lifted loads at all times.
