14m Excavator Long Reach Boom

China 20-25 ton Excavator 12m 14m 18m Three Sections Telescopic Boom Arm with shell bucket for PC ZX HD SY CAT

1. Structure composition of ZHONGHE excavator telescopic arm

• Outer arm cylinder: small arm synchronous steel wire; synchronous steel wire rope fixed seat; synchronous pulley group; retractable pulley; retractable oil cylinder; retractable steel wire rope group; retractable oil cylinder iron pipe; clamp iron pipe; pulley rail; fixed ear seat, fixed ear seat connection rod.
• Middle arm barrel: clamp pipe hose; clamp pipe synchronous pulley; small arm barrel synchronous pulley; buffer vibration glue; and internal middle arm synchronous for fixed pulley.
• Small arm tube: horse head; clamp pipe; expansion steel wire fixed ear seat; small arm synchronous steel wire rope fixed ear seat.

2. ZHONGHE excavator telescopic long boom's advantages

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.

3. Working condition for excavator long boom arm

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

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.

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