tunnel excavator

ZWY-80 type crawler loader, is a continuous production of high-efficiency equipment out of mine. Mainly used in railway tunnel construction, mining tunnel boring, construction of diversion tunnel and the defense caves in the loading operation. Applicable section for the 2.2 × 2.2 meters above the small roadway. The best working conditions of the machine is: Platts rock hardness (f) less than or equal 12, the block is less than equal to 450mm. Grilled by the unit to take forward rock track into its own conveyor, conveyor unloading from the rear of the rocks into the dump truck or shuttle tub. Also can be used backhoe digging arm to take away the rocks Pa, you can also use the bucket to clean up the face. This machine adopts full hydraulic drive power, compact structure, promote the force, taking a wide range of Pa. You can install the whole section of rock, leaving no clear face without artificial aid. The machine is mainly used pilot valve control movement, easy operation, simple and smooth without impact, reliable performance, easy maintenance. This machine has good user friendly design, hydraulic system is cooled by air, there are seats, a canopy, a trip gauge, high oil temperature, oil line plug, motor overload alarm system, greatly reducing the labor of workers strength. Drivers to operate the machine safely, easy, comfortable. Product implementation standard: JB / T 5503-2004 "Legislative claw Backhoe Loader"; Q / XT 26-2008 "Pa coal mine bucket loader."
