Product Overview

The excavator telescopic boom consists of a fixed body, sliding body, steel wire rope and telescopic cylinder. By adjusting the number of sliding bodies, it achieves optimal working radius and vertical excavation range. Designed for deep pit excavation tasks, it works effectively with buckets for handling soil, sand, or coal.

Key Advantages

Three-section telescopic boom constructed with BS900E and Q355B materials for lightweight durability
6mm thickness construction for enhanced strength
Nylon sliders with steel pulleys and centralized lubrication system
External hose pulley design simplifies maintenance and hose replacement
Dual rope safety system prevents uncontrolled extension if main rope fails

40-45	25000	20500	1.8-2.5

Bucket Compatibility

Our telescopic boom supports three bucket types:

Clamshell Bucket: Ideal for subway deep digging projects
Grab Bucket: Provides power for stone handling applications
Standard Bucket: Specially designed for telescopic boom operation

Engineering Features

Four Pulley Design

Features two sliding wheels on top and bottom to separate high-pressure hoses from wire ropes, reducing wear and extending service life.

30mm Main Rope

High-tensile wire rope withstands greater pressure with superior wear resistance for extended durability.

26mm Auxiliary Wire Rope

Enables horizontal extension and retraction of the telescopic arm.

Ningbo Connector

Metal construction offers high compression resistance and easy loading/unloading capability.

High-Quality Nylon Sliders

Nylon material reduces friction while POM material wheels provide high mechanical strength.

Centralized Lubrication System

Multiple access points simplify oil refilling for operators, all conveniently located at the front of the arm.

Engineering Applications

30M Telescopic Boom for XCMG Excavator

30M Telescopic Boom for CAT Excavator

32M Telescopic Boom for SANY Excavator

25M Telescopic Boom for HITACHI Excavator

Frequently Asked Questions

Are you a manufacturer?

We are a manufacturer/supplier with extensive production facilities in Guangdong Province, exporting to over 60 countries worldwide.

What's the difference between clamshell and grab buckets?

Clamshell buckets excel with silt/sand while grab buckets handle stone work better. Grab buckets are generally smaller but more effective for rocky conditions.

Single vs double cylinder design?

We exclusively use double cylinder designs for lower failure rates and easier maintenance, despite slightly higher weight.

What materials are used?

Arm tubes use BS900E with other components in Q355B, all with 6mm thickness for optimal durability-to-weight ratio.
