Underground Mining Excavator

Tunnel Excavator Working Principle of Mucking Loader Power supply system including high voltage cable, transformer,low voltage cable and electrical cabinet,connect power to electrical motor, which drive triple pump change electrical energy to hydraulic energy. While traveling, traveling motor drive crawler travel. While working, operate control handle in drive cab, reversing valve controlled by pilot system, and then control cylinder to work. Conveyor mechanism working

Electric Excavator Traveling mechanism • Traveling mechanism consists of left & right crawler beam, idler and hydraulic actuating device, driving wheel, thrust wheel, tension device, crawler device etc. Traveling device is on both side of equipment, to make the whole equipment to travel forward, backward, and turn around. • Inject grease to traveling stretching device, core bar of tension cylinder drive idle wheel to move forward, confirm the crawlers tension stretching

Mini Tunnel Excavator Daily servicing work For the daily servicing work, the following works shall be completed by specific operators: No. Check item 1 Check the tension of track/chain, left & right 2 Check joints and the base plate of track/chain, left & right 3 Check the mucking loader for oil leakage (The hose joint shall be firmly locked when any hose or hose joint is re-tightened, so as to avoid twisting) 4 Check the tension of triangle belt 5 (In order to avoid

Crawler Excavator It shall be ensured that the track is installed at the correct side. The protruding end of the base plate must be aligned to the chain wheel direction of head end in the lower track section. Connect the track end to the track end bolts. • Hammer the end bolts with sledge hammer, drive pin and conduit during installation without press. • Use a reverse fixing seat when hammering the end bolts in order to prevent damage to guide wheel and drive wheel bearing.

Electric Mini Digger Stop period • The piston rod must be coated with anti corrosive coating, and the air inlet and air outlet of air filter must be sealed. • All devices shall be preheated and test run for 15 min or so after stop for 6 months. • The protective measures must be taken after test run. 9.7.3 End of stop period The following steps shall be taken when the excavator is reused: • The anti corrosive coating must be removed from the piston rod. • The air inlet and air

Tunnel Repair And Maintenance Machine For Coal Mine Product Function and Application: It is a multi-function repair and maintanence equipment mainly used for coal road,half coal road and whole rock roadway in the caol tunnel. It can carry out daily maintainence of breaking and excavating and shoveling for tunnel roof and floor and ribs,and also breaking big rock into smaller to be convenient for loading. The machine have different action of excavation and side excavation and
