Rodder Mechanism 1. Frame Construction: Main frame of the power rodder shall be constructed from rectangular structural steel tubing. Tubing must be steam-cleaned inside and out prior to assembly. Frame must have internal baffle in hydraulic section to ensure complete heat dissipation and precipitation of solids from hydraulic fluid. Vertical uprights must be constructed so that the entire machine is at a 15-degree angle to the rear to lower the Page 5 of 7
height of the operator station. All welds by Metal Inert Gas (MIG) process. Frame leaktested to 5 pound per square inch gauge (psig). 2. Reel Cage Housing Construction: Reel cage housing shall be constructed from rectangular structural steel tubing. All corners mitered and gusseted with 1 / 2 -inch Hot Rolled (HR) steel plate. Reel cage housing shall be on main-frame by heavy-duty pillow block bearing at two points with welded stops for rigidity, the bearings shall have fittings to allow lubrication. Housing shall incorporate fixed guide from drive head to rod reel. Guide shall be spiral type to allow accumulated material to escape and must be constructed from 0.461-inch spring steel wire for maximum wear resistance.

Three drive rolls to be mounted on stationary shafts attached to side plates. Three opposing drive rolls shall be mounted on adjustable shafts to compensate for wear. Clamping force on drive rolls shall be applied hydraulically with pressure proportional to pulling or pushing force to eliminate excessive wear in light load conditions and to allow maximum torque during heavy load conditions. Hydraulic tension shall be applied directly to drive roll shaft. a. Drive Rollers: Drive roll gears shall have rolled instead of cut teeth, and shall be pressed directly onto machined drive roll with a minimum of two set screws or drive pins to eliminate movement and slipping.
