Function: Adjusting Boom Length: The telescopic cylinder allows the boom to operate at different lengths, expanding the working range of the truck-mounted crane.
Product Advantages and Additional Features:
Sequential Cylinder Design: In complex lifting operations, telescopic cylinders can be designed as sequential cylinders to achieve finer boom control. Sequential cylinders extend or retract in a pre-determined order, ensuring smooth, stable deployment or retraction across multiple stages. This design enhances lifting safety and efficiency, reducing risks due to improper operation.
Buffering Feature: To minimize impact and vibration during extension and retraction, the telescopic cylinder can also include a buffering feature that slows the piston rod near the end of its stroke, achieving a smooth stop. This helps protect the cylinder and boom from damage, improving stability and precision during lifting.
