Pow-r Mole setup under gas line
The PD-4 In ActionPow-r Mole set up under gas linePow-r Mole demonstrated its' abilities, by undertaking renovations in a rural midwestern community's down-town area, where the installation of street lamps were needed. The director of the utility department, had three choices.
Price was a heavy consideration. There would be no point in purchasing the equipment if contracting out the work were less expensive.
The director investigated the Pow-r Mole "PD-4" Pipe Pusher. The compact size of the "PD-4" had the ability to maintain line and grade.
Four pits, four feet long and two feet wide were prepared. Each had a small area cut out, for the operator to stand in.
A gas service line was encountered in the first pit, but was of no consequence as the Pow-r Mole set up neatly under the line. Hydraulic power to supply the Pow-r Mole was obtained by utilizing the town tractor.
|Pushing began at 8:30 and by 10:25 one eighty-five foot run, down the sidewalk had been completed.
The push rods were maintained at a depth of twenty-two to twenty-four inches throughout the push and emerged at the target trench precisely on line and grade. A 2-1/2" soil expander was attached to the rod and the conduit was attached to the expander. As the push rods were extracted, the conduit was pulled under the sidewalk.
"PD-4" rotated 90 degrees for street crossing
At 11:25 the machine was rotated 90 degrees and the rod was pushed 50' under the main street to a target hole, where it emerged on target at 11:55. The conduit was pulled under the street and the Pow-r Mole was moved to the second section of the sidewalk. By 3:10, the conduit was installed and the equipment had been picked up and loaded into the truck.
In all, two-hundred and ten feet of conduit had been installed with three seperate pushes under the sidewalk and street, in one easy day of operations.
