SKM230 Hybrid Power Crawler Full Hydraulic Drilling Rig
1, new propulsion system
use hydro-cyclinder chain pully propulsion system, compact structure, big lifting force and stablity.
2, centralized controls system
It features advanced hydraulic system and air way system, All moves are centralized controlled, easy and convenience.
conducting hydraulic valve to realize different moves of drill arm, guarantee drilling rig stable and high efficiency for drilling.
The special designed unidirection throttle valve in the hydraulic system can realize stepless speed regulating for rotating, to increase applicability for various rock layers and work efficiency.
3, reliable hybrid power
providing YC4108 4-cylinder turbo diesel engine and electric motor for this drilling rig. operator can use diesel to run this machine in area where there is no electric power, otherwise can use electric motor.
water tank and hydraulic oil radiator guarantees diesel, electric motor and drilling rig hydraulic system operating safely and reliably.
single connected gear pump provides driving force for propulsion system and rotating system respectively via diverter valve, The hydraulic system is more stalbe and reliable.
4, air lubricator
The specialized air lubricator atomize lubricant using ari source from air compressor and send to hammer. It will lubricate and protect the hammer reliably and prolong hammer's working life.
5, strong power head
Slewing drive adopts planetary gear reductor and oscillating motor with foreign advanced technique. It moves stably with low speed and high torque.
6, diesel protection device
natural inhaling system combines of desert air filter, second air filter and oil filter to improve the applicability for severe environment and working life of diesel
The drilling rig uses clean air source from air compressor and disconnect the natural inhaling way of diesel.
Unidirection throttle valve can adjust and stablize air inflow of diesel.
air dryer can remove the water of air source of air compressor efficiently.
7,reliable four wheel and one belt
integrated crawler belt installs conveniently with reliable performance.
care chain wheel, tensioner spring and turgor cylinder can guarantee suitable crawler belt tensioner degree.
8, very flexible drill arm
