The Columbia Kodiak Cub Rig Walking System is designed to move rig substructures. This system uses Hilman rollers paired with over-sized lift cylinders and a low pressure hydraulic system. The Kodiak Cub is designed to lift and move the entire rig substructure and is customized to fit and attach to your rig.
The Kodiak Cub Rig Walking System is designed to connect externally to either slingshot or box-on-box subs. Columbia provides structural engineering surveys and analysis to determine strength and feasibility of attachment. The efficient material usage allows for light loads for trucking from pad to pad.
CAPACITY: From 1,200,000 lbs up to and beyond 2,400,000 lbs
SAFETY FEATURES: The hydraulic system is a safe, low pressure system, that ensures smooth operation. The main lift cylinder hydraulic circuit is equipped with counterbalance valves. These valves will hold the cylinders in position in the event of a hose rupture or breakage. Emergency stops are mounted on the power unit, as well as the hand held controls. The E-stops will shut down the hydraulic power unit motor and valves.
WALKING CYCLE: Four jack cylinders lift the rig, then four travel cylinders push the substructure along the walking feet on Hilman rollers. The jack cylinders then lower the load and the travel cylinders retract for another pushing cycle. Steering adjustments are made with ease by manually steering while the load is off the rollers.
HYDRAULIC POWER UNIT: This system can be powered by a Columbia hydraulic power unit, requiring only a 3-phase power connection for operation. Or, your system can be configured to utilize existing rig hydraulics. The HPU can be located within the unit itself, near the rig modules, or mounted within the rig structure.
ADDITIONAL SYSTEM FEATURES INCLUDE:
- Expandable to meet any lifting requirement
- Easily adjustable, accurate steering
- Can be retrofitted to existing rig substructures
- Movable in trailer-sized loads
