Production Introduction
For excavators that only occasionally do large-scale work, the extended arm is a good choice. It can be installed on the standard arm of the original excavator to increase the working range. If it is not needed, it is also very convenient to disassemble. The company's two-section extended arm is made of high-strength alloy plate without changing the performance of the original excavator, which greatly improves the working range. The working range is 13 meters to 30 meters. The extended arm of the excavator has a wider range of use and more functions It has the functions of digging, breaking, hook cleaning, drilling, bulldozing, etc. From a certain point of view, it actually realizes the multi-purpose function of one machine. The extended arm of the excavator improves the mechanization of the excavator, and the 360° pressure-free rotation of the body provides convenience for the subsequent construction of the equipment. In addition, the equipment can work in some relatively narrow areas, which increases the convenience of construction sex.Technical Parameters：
