Tandem pump for Terex LRT450

The tandem pump 707 4633 functions as a hydraulic component that integrates two or more independent pumping sections on a single shaft or within a shared housing. This configuration allows the machine to supply hydraulic fluid to different circuits simultaneously, enabling the crane to perform multiple operations such as boom lifting, outrigger extension, and superstructure rotation without interference between functions. By separating these hydraulic paths, the system maintains consistent pressure and flow across various crane movements.

This component is compatible with Terex LRT450 and LTR 450 NS1 models. It serves as the primary source of hydraulic power for the various cylinders and motors responsible for steering, braking, and structural positioning of the crane. Tandem pumps are generally utilized in heavy machinery to consolidate multiple hydraulic requirements into a single, space-efficient assembly, which simplifies the overall hydraulic architecture of the equipment.

Tandem pumps operate by converting mechanical energy into hydraulic energy, with each section typically dedicated to a specific hydraulic circuit. This setup ensures that the flow requirements for different crane functions are met independently, which is necessary for complex operational tasks. Proper maintenance of this pump is necessary to ensure the hydraulic system remains responsive and capable of handling the operational loads required by rough-terrain cranes.
