Engraved-plate labels denoting function, above each control and gauge; stick-on labels denoting direction of control 7. External weatherproof light shall illuminate operator control panel E. 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

6 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 inch spring steel wire for maximum wear resistance. Guide shall also include adjustable roller to reduce stress on rod. 3. Rod Reel Construction and Installation: Rod reel shall be constructed from 7 / 8 -inch diameter HR round stock. Reel shall have a minimum of 12 spokes diagonally braced to hub. Diameter of completed reel shall be 74-inches to prevent a set from occurring in rod. Rod reel shall incorporate 3 / 16 -inch x 4-1 / 2 -inch HR flat band around circumference to reinforce spokes, provide area to support rod and facilitate rod installation. Rod reel hub shall be manufactured from 2-inch Cold Rolled (CR) stress-proof steel supported on each end by 2-inch four-bolt flange bearings. Flange bearings shall be mounted with wedge spaces to align bearing with angle of reel and have fittings to allow lubrication.

Drive Head Design: Rod drive head shall contain three (3) pairs of drive rollers directly driven through pinion gears by two hydraulic motors. 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. Drive rolls to ride on a minimum of two radial and two thrust bearings. Bearings to accept a minimum of 1-1 / 4 -inch diameter stress-proof drive roll shafts. b. Hydraulic Drive: Hydraulic fluid shall be plumbed directly from lateral valve through hydraulic swivel barrel to drive head. All plumbing to motors shall be steel tubing with JIC flare-type fittings. No black pipe or flexible hoses to drive motor. Lateral drive to feed motors shall be in a parallel fashion for low-speed/high-torque drive and in a series fashion for high-speed/low-torque drive. Gearing shall be internal for structural integrity, to shorten span between torque load points, and to eliminate additional wear points associated with chains, keyways, bearings and shafts.
