undergroud rock loader for underground continuous mucking and discharging work
I. INTRODUCTION:
MLT100S Mucking Loader is crawler based hydraulic driven loader. It is widely used for rock/ore excavating in hydro power tunnels, underground mining of gold, copper and metal ore etc.
Power (Dual Power System, optional);
Working, traveling and unloading of the mucking loader are all driven by hydraulic pump, which is driven by electrical motors built in the loader. This kind of powering system allows the loader to give ZERO exhaust air emission in working operation.
In addition to this, one diesel engine is given to drive the loader when long distance traveling is needed, or electricity is not available.
Conveyor System
The conveyor system is designed with steel scrapper and chain, more durable and robust in working.
Boom and Arm
Boom and arm of the loader is box structure, it is strong in strength, light in weight, bigger in working range. Boom and arm are joined with floating pin axles; this gives longer service life to the Jib and arm.
To meet the different working height in the tunnel, the arm can be made into extendable arm structure, or hydraulic excavator structure arm. The extendable arm allows the loader to work in low height tunnel, while the hydraulic excavator structure arm allows higher productivity than the extendable arm structure.
Cable Reel.
Hydraulic cable reel is optional. With electrical cables, it will be more convenient for MLT muck loader travelling and working in tunnel
