SRMA Gang Rip with Shifting Saw

The new Hasko SRMA ShiftMaster Gang Rip is a Heavy Duty, High-Speed Roll Feed Shifting Saw Gang Rip having approximately 18.75″ of usable saw area. A wide range of saw solutions can be obtained via the use of a Hydraulic Saw Positioning System. Saw solutions are determined based on customer specifications and inputs from Board Scanning Systems.

The standard machine’s 3″ diameter double key arbor is powered by a 125 H.P. 3450 R.P.M. direct-coupled motor. A “Quick set” Hydro-sleeve outboard bearing assembly provides support at end of arbor. Arbor braking is achieved through the use of an air actuated disc and dual caliper braking system.


Designed for high-volume ripping of strip and plank flooring, truck flooring, lineal moulding, frame stock, dimension stock, stacking sticks and more, the SRMA Shifting Saw Gang Rip is good for kiln-dried hardwoods and woods of all species.
