The Duct Rod Pushing machine has been designed to provide an effective and safe method
of rod installation and removal. The system installs rod of 1/2” overall diameter at up to 130 ft/
min into pre-installed sub-ducts.
The machine is protected by preset pressure relief valve and preset pressure sensor.
The hydraulically powered rod feed system controls the rod. The electronic control system
displays speed, distance, direction and the preset pressure sensor provides automatic protec-
tion against duct obstruction.
The system comes mounted on a sturdy anti-corrosion, height adjustable, wheeled, tubular
steel trolley unit for ease of site maneuverability, and is powered by a hydraulic supply system
operating at 2030 psi x 5.3 gallons/min.
The rod pushing unit can be easily detached from the trolley and located in a trench or man-
hole (depending on the size of the manhole).
The unit is supplied with two (2) x hydraulic hoses x 23 feet and a 26 foot long emergency
stop lead.
