Telescopic cylinder for Link-Belt HTC-8675

The telescopic cylinder acts as a hydraulic actuator that facilitates the extension and retraction of the boom sections. By managing the length of the boom, this component directly influences the reach and lifting height of the crane during operation. It is engineered to provide a significant extension range while maintaining a compact profile when fully retracted.

This specific unit is compatible with the Link-Belt HTC-8675 hydraulic truck crane. It serves as the primary component for the boom extension system, allowing operators to adjust the crane geometry to meet the requirements of various lifting tasks. The design utilizes multiple concentric stages that extend sequentially under hydraulic pressure to achieve the necessary boom length.

Telescopic cylinders function by using hydraulic fluid pressure to move internal stages, which allows for a long stroke within a limited installation space. These actuators are subjected to axial loads and bending forces during lifting operations. Proper maintenance of the hydraulic connections and internal seals is necessary to ensure the consistent movement of the boom sections and to prevent fluid leaks that could affect the operational control of the crane.
