HDD pullback assistance
Push from the exit side while the drill rig pulls, reducing pullback load on long crossings.
The UNI-PF250 delivers continuous, controlled axial force for demanding HDD pullbacks, microtunnelling and pipe-jacking operations.
Stroke-based systems repeatedly stop, retract and re-engage. The UNI-PF250 maintains movement through its four-track conveyor system, helping avoid static-friction spikes and shock loads.
Repeated restarts interrupt progress and must overcome static friction again.
Four driven tracks grip the pipe and deliver smooth, controllable forward force.
A modular architecture combines serious pushing performance with practical transport, installation and operator control.
Balanced at 45 degrees to distribute radial force around the pipe.
Hydraulic control adapts clamping force to pipe diameter and wall thickness.
Three modular blocks simplify delivery and crane-free site assembly.
Use the autonomous power pack or connect to a suitable HDD rig hydraulic system.
Panoramic control station with integrated diagnostics and optional video monitoring.
Steel-backed rubber pads provide durable grip and controlled friction.
An optional pad-set configuration extends supported pipe diameter to 20–56 inches. Final configuration should be confirmed for the specific project.
Push from the exit side while the drill rig pulls, reducing pullback load on long crossings.
Maintain continuous pipe feed behind the TBM and steady forward progress.
Provide primary or supplementary force at the drive shaft.
Push prefabricated steel pipe as the TBM excavates the bore face.
