HEADS FOR ROTARY DRILLSHR Series |
|
DESCRIPTION AND APPLICATION
The ROTARY HEADS SHR series are designed purposely for drilling machines.
They are equipped by two hydraulic motors with variable displacement which transform the oil pressure into motion.
The hightorque value is givenby two planetary gearboxes that transfer the motion to acrown gear connected to the main shaft of the rotary head.
The head can be shaped through the drive of Kelly bars or continuous flight augers for C.F.A..
