Main technical features and functions:
This equipment is mainly used for rock loading and bottom cleaning excavation operations in flat and inclined roadway excavation.
The excavator working arm is a three section arm structure, consisting of a boom, a secondary boom, and a boom. The slewing mechanism of the auxiliary arm can drive the boom and bucket to achieve 360 ° unrestricted continuous rotation, in order to adapt to the narrow and complex working environment underground.
Excavators are equipped with backhoe and backhoe functions, which have a wide range of uses,
The excavator frame can rotate 360 degrees;
The whole machine is equipped with a front bulldozer shovel, which is used to level the tunnel working face and stabilize the body.
The hydraulic system adopts hydraulic pilot for main functional control, and the equipment has good maneuverability.
The main components of the hydraulic system, such as the main pump, main valve, rotary motor, oil pipe assembly, hydraulic hose, etc., are all selected from well-known domestic or international brands.
Adopting advanced hydraulic system design, the main pump and main valve of the hydraulic system are respectively equipped with load sensitive variable displacement piston pump and load sensitive directional valve, which improves the working efficiency of the hydraulic system and reduces heat generation.
The main structural components are made of Q345 high-strength steel plate, which has high performance strength, wear resistance, long service life, and can adapt to harsh underground conditions
