What is an excavator telescopic arm

A telescopic arm for excavators consists of a stationary frame, a sliding mechanism, a wire rope, and a telescopic hydraulic cylinder. The excavation depth and operational radius can be adjusted by modifying the number of sliding sections. It is often equipped with a bucket for digging deep pits and handling materials like soil, sand, and coal.

The two-stage telescopic boom utilizes LG700 steel, while Q355B is used for other structural components to ensure durability and reduced weight. Features include:

  • 22-ton heavy-duty bucket cylinder

  • Enlarged reel with reinforced spring plates

  • Multi-layered reinforcement at the bearing points

  • LG700 high-strength steel box structure

  • A strengthened pivot end for improved resistance to excavation forces

FAQ(Some frequently asked questions):

Q: Are you a manufacturer?

A: Zhonghe machinery offered a wide range of attachment parts for excavators and dozers. Such as long reach arm, demolition arm, telescopic arm, standard bucket, rock bucket, cleaning bucket, tilting bucket, etc. We know that the perfect combination of high-quality cast steel products and a moderate price is the key to the success.

 

Q: Is the length of the telescopic arm the total length or the digging depth?

A: The length of a two-stage telescopic arm refers to the digging depth. For example, a 14-meter telescopic arm means that the maximum digging depth is 14 meters, so it is called a 14-meter telescopic arm. The actual arm length is not only 14 meters.

 
Q: What material is the telescopic arm made of?
A: The arm tube of the telescopic arm is made of a690 or HG785 material, and the material of other parts is a355B material.
 
Q: What are your terms of payment?
A: We prefer T/T (50/50) through Ali Credit Insurance as a trial order.
 
Q: Are you always delivered on time?
A: We can't promise about the sea freight but what we can do is shorten our lead time while keeping the same quality level. So there will not be any problem even if the sea freight is delayed for a couple of days.
