Product Description

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

Standard Specifications

Excavator(ton)	Max Depth(mm)	Effective Length(mm)	Bucket Capacity(cbm)
6-10	10000	7600	0.2-0.3
11-15	14000	10500	0.4-0.6
20-30	16000	12500	0.8-1.5
30-35	20000	15500	1.3-1.66
40-45	25000	20500	1.8-2.5

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.

30mm Main Rope

Thicker wire ropes withstand greater tension and pressure, with high wear resistance for long service life.

26mm Auxiliary Wire Rope

Enables telescopic arm retraction when extended horizontally.

Ningbo Connector

Metal construction with high compression resistance and expansion capacity for easy loading/unloading.

Nylon Sliders

Reduces grinding with POM material sliding wheels for high mechanical strength and rigidity.

Centralized Lubrication System

Multiple access points for convenient lubrication oil refilling, all concentrated at the front of arm.

Engineering Case Studies

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.
