The MPP 100K and 50K RC/RAB Top Drives are high torque rotation units that can be configured for both reverse circulation and rotary air blast drilling. The top drives feature planetary gear box and bent axis piston motor drives, and a robust main gearbox, spindle and swivel assembly. The 100K and 50K top drives are ideal for large diameter drilling and pilings. Conversion kits may be ordered from Pinnacle Drilling Products (PDP) to change from RC to RAB or RAB to RC. The drives are also available with multiple accessories including a heavy duty stand, hydraulic hoses and quick couplings, guide blocks, hex drive sockets, spreader bars and discharge adapters. When coupled with PDP’s line of portable hydraulic power units, 40” cyclones and air manifolds, the MPP 100K and 50K top drives are the perfect tools for large diameter/piling drilling projects.
