Dominator J 8-36


No Dig Technology





J 8-36


 The Dominator® J 8-36 lateral reinstatement cutter is one of the revolutionary cutter designs in our Dominator® series.  This cutter works in 8" to 24" relined pipe, with the capability of working in up to 36" pipe with an additional skid package.  The motors are isolated in their own water-tight chamber eliminating the problem and cost of water damaged motors.  The chamber's water-tight quality is due to the placement of a captured o-ring, and because the o-rings cannot drop out, this design also permits quick assembly and disassembly.  Further, the motor chamber is isolated from the feed and rotation mechanism for ease of assembly and disassembly.  This cutter's capability of being disassembled and reassembled in approximately 20 minutes is due to its revolutionary 8 moving parts design; there is no air solenoid, rather the air solenoid is on your truck.  Most of the gears and feed mechanisms are manufactured from temper hardened stainless steel and bronze.  The cutter is machined from the highest grade of stainless steel and bronze available and has no outside air tube, but rather an insulated internal air channel.  The head design incorporates a pinionless, quick-change design, and only one adjustable gib to ensure reduced adjustment time and maintain the highest degree of accuracy.  The cutter can be wired for 4, 5, or 6 wires to accommodate most of our competitors' systems.

        The J 8-36 is 37 inches long with the ram in and 47.5 inches long with the ram out, weighs 130 pounds, and has a body diameter of 6.5 inches.  It has a ram travel of 10.5 inches.  It has 3 motors at 24-30 VDC.  It requires 24 volts of electricity to operate.  The cutter has an air requirement of 38 CFM @ 100 PSI.  The Dominator® J 8-36 operates with our Generation II Infinite Control 430 series control box and any of our air motors (depending on the line size you are working in).

                            Jumbo 1236


The Jumbo 1236 lateral cutting machine was developed in 1987 to fill the need for a reinstatement machine for large diameter pipe.  Since its inception, the Jumbo 1236 has been unmatched in the industry for its rugged and durable performance characteristics.  Weighing in at over 180 pounds and a reach of 10 inches to 36 inches, the Jumbo 1236 continues to be the largest cutter on the market.  Paired with our .9 HP air motor and infinite head adjustability, the Jumbo 1236 has an overall length of 32 inches.  The ram rotation on the unit is 360 degrees continuous with a ram extension of 15 inches and head adjustability of 4 inches.  The body of the unit is machined from stainless steel and measures 8.5 inches in diameter.
