Boom Arm

Telescopic arm, a kind of boomarm, is a mechanism fixed onto an excavator. Under the action of thetelescoping cylinder, the movable part extends or retracts for larger diggingradius and reasonable loading height.

The telescopic arm is divided into sliding boom arm and sleeve type boom arm.
Sliding Boom Arm (TelescopicArm)
The movable part of the telescopic arm slides along the fixed part underthe action of the telescopic cylinder and slide block. The sliding boom arm ismainly composed of the fixed part, mobile part, slide block, and telescopiccylinder, etc. This type of telescopic arm provides the advantages of largeload capacity, simple structure, and low manufacture cost. Generally, it has astroke within 4m and is generally designed as a two-stage telescopic arm foruse on excavators for deep pit applications.

Sleeve Type Boom Arm (Telescopic Arm)

The first segment of the sleeve type boom arm is fixed, while the restsegments are movable. All the movable parts are put inside the fixed part like sleeving, which extend or retractby means of the cylinder. There is only one segment and two or more movablesegments for the sleeve type boom arm. The number of cylinder is one more thanthat of the movable segments. This type of telescopic arm provides largerworking radius. Due to complicated structure and high manufacture cost, it iscommonly designed into over three segments, and used for excavators applicableto deep pit or work at high altitude.
