Description
YYT28 hydraulic leg drill:its powerful percussion and rotation, low-power, low noise, long life, obvious advantages and so on, is widely used in rock excavation project. YY26 hydraulic rock drill absorb advanced technologies at home and abroad, it also has the unique advantages in the following:
(1) The three main functions automatic Control (patent): percussion,rotation,push synchronization. Improve double footage speed, lower more than half power consumption.
(2) Through-hole oil motor (patent): no need for mechanical transmission, small size, long life, and great torque.
(3) Cooling-water system (patent): all-round cooling machine, blow slag cleanly.
(4) Flexible hydraulic legs (patent): single drill leg's energy ; reduce the probability of stick the rod, benefit a smooth operation.
(5) Brake-chuck (patent): ensure the drillman safety when the rod tail breaken, the structure lightweight, action flexibility.
(6) The pressure lubricating oil chuck bushing (patent): chuck bushing and seclude bushing lubricate directly, reliable and convenient.
(7) Complete specifications: a power station with multis-rig, flexible portfolio.
