Product Description
Excavator Telescopic Boom in operation

The excavator telescopic boom consists of a fixed body, sliding body, steel wire rope and telescopic cylinder. By changing the number of sliding bodies, it achieves ideal working radius and vertical excavation range. Designed for deep pit excavation tasks when combined with a bucket, it's ideal for grabbing soil, sand or coal.

Key Advantages
  • Three-section telescopic boom made of BS900E and Q355B materials for lightweight durability
  • 6mm thickness construction for enhanced strength
  • Nylon sliders and steel pulleys with centralized lubriPCion system
  • External hose pulley design for easy maintenance and replacement
  • Separated hose and main rope system to reduce friction and failures
  • Double rope safety design prevents arm extension if main rope breaks

A: Shell buckets excel with silt/sand for high volume digging, while grab buckets perform better with stones despite smaller capacity.
Q: What is the material of the telescopic arm?
A: The arm tube uses BS900E with other parts in Q355B for lightweight durability at 6mm thickness.
