Telescopic dipper Arm for Excavator

Description

Wear resistant, high temperature resistant square steel (Q690 or higher performance materials) is adopted by POIN, through high precision machining, so that the first, second and third arm are closely intertwined. This type of telescopic boom has greater depth of work and vertical excavation capability. Telescopic boom is generally configured with shell bucket, and the excavated soil is relatively soft.

Working Condition

Application

Mainly used in small radius of rotation, but deep digging environment.  It is the first choice for urban subway construction and deep excavation of civil air defense engineering.

In order to meet the demand of large quantities of foundation trench construction, POIN collaborates with SANY and CSCEC, to launch the telescopic arm clamshell product. It not only lays the POIN’s foundation for becoming the pacesetter of small and medium-sized pile machinery industry, but also extends CSCEC’s series of excavator construction methods. So its multi-functional assistant is the trend in the future with the growing number of excavator.

POIN series of telescopic boom products perfect the telescopic boom’s function to achieve great depth of excavation which expands excavator application. It will be widely employed in the subway construction and deep foundation pit soil construction of high-rise building.

Excavator uniting with matched telescopic boom clamshells can fulfill the wildly deep digging soil work, which is the most effective tools for underground engineering construction. Moreover, its design is simple to control, easy to install and convenient to maintain, which realizes reduce cost and increase efficiency.

Telescopic boom’s matched POIN series of clamshells also uses hydraulic power, which has characteristics of large holding force, flexible operation, large capacity, high reliability and stability. Besides, being added to various excavators, telescopic arm, rotating drill platform can be used to dig directly and ditch simply to apply to city’s supporting seepage control engineering.

This product is widely used in developed countries, and there are only a small amount of Carterpillar and Hitachi second-hand products to be used in the domestic .POIN series of telescopic boom products are not only fill the domestic gaps in the field of engineering machinery market, but also becomes another prerequisite products in the field of deep foundation pit construction.

Our Long Reach Booms fit most brands and models, include but not limit below Models.
