Long arm excavator compared with ordinary excavator?
Because of the limitation of excavator's working range due to its own defects, there are often many construction sites that need excavators to expand the construction range, but the existing large and small arms can not meet the requirements of the site, so the long arm excavators (long arm excavators) are also needed.
The so-called long arm (i.e. extended arm) is to lengthen a part of the original big and small arms or completely abandon the original big and small arms to replace the extended big and small arms so as to achieve a wider, deeper and higher working range and improve the economic benefits of construction.
Uniqueness: at present, subway construction has been launched all over the country, and river dredging and pollution control projects for environmental protection are also in full bloom, so the market demand for long arm excavators is very large. The long arm excavator will occupy its unique place in this dynamic market segment.
Folding editing function of long arm excavator: the long arm of excavator is divided into two-stage type, three-stage type and four-stage type. The two-stage type is mainly applicable to the transportation of soil and sand, concrete and other buildings, the trimming of highway slope, dredging and dredging of river channel, the excavation of building foundation, river channel, deep ditch and other earthwork; the three-stage type and four-stage type are mainly applicable to the disassembly of high-rise buildings. The most important thing is: according to the needs of the weight of the extended arm, the weight of the rear butt counterweight should be increased appropriately to maintain the front and back balance. Avoid accidents in excavator operation.
