• Working condition for excavator telescopic long boom arm:

  Mainly used for forestry operations(with grabber) and load&transport soft mud(with shell bucket/standard bucket)

Arm barrel using high strength manganese plate, pulley group all using steel, bearings using Luoyang bearing, all wire rope using multiple wire rope; optimize arm barrel design, the expansion arm need not replace the wire rope and pulley.

First flashlight,oil pipelines are hidden inside the body, which ensures them will not explose during working.

Second flashlight, inner part of the arm barrel is double-sleeve, reduce greatly steel pipe shaking and joint loosening during frequent go and back,prevent oil leakage problems.

The three-stage pull arm(with grabber) is aimed at a 12-15 ton machine for modification, the length of the modification is from 21-28 meters long, matched with hydraulic rotating wooden gripper, it is mainly used for carrying out short-distance timber transport operations down or up the hillside. Basically, the scope of operation ranges from 5 to 28 meters, and the expansion time is basically kept at about 15 seconds for expansion and contraction, mainly for eucalyptus, pine and other economic forest, grab the weight of 1-2 tons below, but no limits of tree length.

The three-stage telescopic arm(with bucket) is used to load and transport sand or soft mud.
