Product Description
ZH Telescopic Excavator Boom Q355B Material for 20-50Ton Excavators 0

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 lubrication 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

Bucket Compatibility

Our telescopic booms support interchangeable use of digging buckets and grab buckets:

  • Clamshell bucket: Ideal for subway deep digging projects
  • Grab bucket: Provides power to grab stones, more efficient for rocky terrain
  • Standard bucket: Specially designed for telescopic boom applications
Engineering Features
Four Pulley Design

Two sliding wheels on top and bottom separate high-pressure hoses from wire ropes to reduce wear and extend service life.

Frequently Asked Questions
Q: Are you a manufacturer?
A: We are a manufacturer/supplier with a large factory in Guangdong Province, exporting to over 60 countries worldwide.
Q: Why does the telescopic arm have the difference between a shell bucket and a grab bucket?
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.
