Strong and reliable power
It using 4-cylinder diesel enging for power,traction power larger and Climbing Ability,libration smaller and Working Stability.
It using air suction system and three-level air filter, has enhanced adaptive ability and and prolongated use life.
New boom
It using the better trolley travelling mechanism and the circular boom, novel structure, convenient adjustment, expands the range of drilling,It can drill the hole low level.
Safety and stability in travelling mechanism:
Low gravity center,high ground clearance, It can travel on the rough terrains. Special wheel motor drive, strong climbing ability, low failure rate.
Advanced automatic balancing and braking system make the dill can travel stability,driving safety.
Prevent to take off the chain set is improve the properties of dirll.
It can travel without compessor.
Powerful feeding and rotating system
New slewing mechanism is composed of cycloid hydraulic motor and the planetary gear reducer, provides a powerful torque, reduce the rate of drill
High power hydraulic motor drive feed mechanism can produce 20 kn lifting force, to adjustregulating valve for the best propulsion.
