LITTLEFOOT
RIG WALKING SYSTEM
SPECIFICATIONS
CAPACITY
Standard beam lengths from 20’ to 70’. Beams can be pinned together for increased lengths and
capacities. Scalable capacity to 12,000,000 lbs. or more.
WALKING SPEED
The standard configuration will move 50 feet per hour (15 meters per hour).
SAFETY FEATURES
The Littlefoot Rig Walking System uses a safe, low-pressure hydraulic system. The main lift
cylinder hydraulic circuit is equipped with counterbalance valves.
In the event of a hose rupture or breakage on the machine, these valves will hold the cylinders
in position. Emergency stops are mounted on the power unit as well as the control pendants. The
E-stops shut down the hydraulic power unit motors and valves.
WALKING CYCLE
Lift cylinders raise the rig. Then, travel cylinders push the module along the foot plate on Hilman
rollers. The lift cylinders then lower the load and the travel cylinders retract for another push
cycle. Steering adjustments are made manually while the load is off the rollers. Automated
steering is available.
HYDRAULIC POWER UNIT
The 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 power unit can be located on top of the unit itself, near the rig modules, or within the rig
structure. Optional diesel-powered units are available.
PAINT
We prepare surfaces for the paint process with a thorough blast cleaning and apply a three-part
epoxy paint system in the customer’s choice of color.
Columbia Industries LLC reserves the right to make changes to specified features and components without notice.
