Air chamber assembly for Grove RT 865

The air chamber assembly, part number 9049105499, functions within the pneumatic braking system of Grove heavy machinery. This component converts compressed air pressure into the mechanical force required to actuate the brake shoes or pads, enabling the controlled deceleration and stopping of the crane. It serves a central role in both the service and parking brake systems, ensuring the machine remains stationary when required.

This assembly is compatible with Grove RT 865, RT-855B, and RT865 models. It consists of a housing, an internal diaphragm, a return spring, and a pushrod. When the brake system is activated, air pressure enters the chamber, forcing the diaphragm to move the pushrod and apply the brakes. Regular inspection of the diaphragm and housing is necessary to prevent air leaks and maintain consistent braking performance across the machine's operational life.
