Case weldment for Terex BT4792

The case weldment, identified by part number 226887, functions as the primary structural housing for the extension cylinder on the Terex BT4792 crane. This component forms the outer body of the cylinder assembly, providing the necessary enclosure for the internal piston and rod while containing the hydraulic fluid under pressure during operation. Its design facilitates the extension and retraction movements required for crane boom positioning.

This component is specifically engineered for the Terex BT4792 extension cylinder and features dimensions of 6.000 and 275.438. As a structural element of the hydraulic system, it maintains the alignment and integrity of the cylinder assembly under the operational loads experienced by the machine. Proper installation of this part ensures the cylinder remains sealed and capable of managing internal hydraulic pressure during lifting tasks.

In hydraulic systems, a cylinder case weldment acts as the pressure vessel that houses the internal sealing components and guides the piston stroke. It must maintain its shape and structural stability to prevent fluid bypass and ensure that the hydraulic force is effectively transferred to the boom extension mechanism.
