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.

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.
