It is precise because the standard arm length of excavator can not meet some working conditions, more and more excavators use long arm to fill this gap. For example, in the fields of foundation engineering of deep foundation pit operation, construction and maintenance of buildings, demolition of high-altitude work or river cleaning, in order to efficiently and quickly complete the indicators required by the project, it is necessary to use the lengthened arm.

Dredging of river channels

    The expansion of the city, the demolition of the old city. For safety reasons, the government opted for three extended arms on the lower floors rather than blasting demolition. A middle arm was added to the original two lengthened arms. The middle arm can greatly protect the safety of the driver. Three extended arms are operated with a hammer or hydraulic shear.
