Product introduction

Multi-function shovel digging machine, also known as the front dig shovel two busy one machine, two busy, many areas have different names for this machine according to different habits.
The shovel digging machine produced by our company is suitable for small space, can drive in both directions, fast and convenient for back control, with side shifting, can move left and right, greatly improve work efficiency, hydraulic lock with legs, improve work safety , silencer, air filter built-in design, reducing working noise.
The multi-function shovel digging machine is compact, flexible and convenient, energy-saving and efficient, coherent compound action, spacious cab independent console, simple and easy to operate. The excavator is designed as a slideway with the advantages of folding side digging, free sliding, preparation There are auxiliary oil passages, and the upgradeable utility aids can achieve the function of real multi-purpose.
In addition to the shovel digging function of different specifications and different operations, the multi-function shovel digging machine can also complete the work of bulldozing, lifting, loading and unloading other materials if the different working devices are replaced, greatly improving the efficiency of the machine. . It can also carry out excavation, shovel loading, road surface crushing, leveling the site, excavating ditches, laying pipes and many other industries.
After each work of the multi-purpose shovel digging machine, it is necessary to carry out the necessary repair inspection of the machine. Because of the influence of the construction environment, the functions that are not used are closed and folded as much as possible, so that the operation in a narrow space can be realized to the utmost extent.
