Excavating machine for coal mine
Usage and features of equipment:
1. Compactly cutting reducer can ensure the high reliability, international brand bearings and cutting teeth can guarantee long working life.
2. The body has a split structure, front and back body adopt "dumbbell pin" connection mode, which can withstand greater load.
3. The travelling motor and reducer are of high integration with high driving force and reliable performance.
4. The transported is flat structure and chain length varies a little when shovel board elevation and undercover for linear motion.
5. The secondary conveyor rotary table has automatic self-aligning compensation device, that can compensate boring machine certain deviation blanking problem.
6. Hydraulic system has the function of constant power, pressure cut off and load sensitive control and has the advantage of energy conservation and efficient.
