Excavator long reach fronts introduction
The excavator two-section extended arm is a group of excavator front-end working devices specially designed and manufactured in order to expand the working range of the excavator according to the requirements of working conditions. The connecting part of the excavator must strictly comply with the connecting size of the original excavator in order to facilitate the installation and use of the equipment. It is precisely because the standard arm length of excavator can not meet some work situations, more and more excavators are using the extended arm to fill this gap, such as the foundation engineering of deep pit operation, the construction and maintenance of high-altitude operation of building demolition or river cleaning and other fields, it is necessary to use the extended arm in order to efficiently and quickly complete the project requirements of the indicators.
Application scope of two long arm of excavator: (1) foundation and earthwork foundation construction. (2) Subway, deep pit excavation. (3) Municipal engineering, river cleaning. (4) highway slope repair, river dredging. (5) Port construction, railway, tunnel digging. (6) irrigation of farmland water conservancy, underground pipeline laying. (7) forestry reclamation, mining and excavating (8) special uses
