Placing the Equipment into the line
Locate the back of the truck so that the cable reel lines up in the direction of the
pipeline to be inspected. Allow room to work around the opening while carrying the
equipment.
Follow cable grip, bridle, and watertight connection instructions. Re-check the pipeline
size and extension adjustments. Do not let cable “loop” at the location where it enters
pipeline. Use guide poles with hook to keep the tractor stable as it enters pipeline.
Caution: Maintain control of equipment while lowering and lifting from
manhole.
Most equipment damage occurs when camera is lowered into hole.
Pull camera/tractor far enough into pipeline to clear the bridle or cable grip.
Set the cable guide. Use double roller and/or single rollers, for protecting the cable and
allowing it to slide down the hole without drag on the line. Use enough poles to clear
top of the manhole by 2 feet.
Caution: Watch out for people, power lines while handling the
downhole poles.
Lowering camera/tractor into line
Put cable reel into “freewheel” and reel off enough cable so camera and tractor can be
lowered into the bottom of the manhole. Place lowering rope ring under the top front
runner or front of camera. Support weight of tractor and camera with the cable in one
hand and rope in the other.
NOTE: RST skycrane can be used in place of the cable and rope method.
Slowly lower the front of camera into manhole to clear manhole ring. Lower tractor and
camera to the bottom of manhole facing camera in the direction of the pipeline to be
inspected. When tractor and camera are resting on bottom of the manhole, release the
rope ring and remove it from the manhole. Check all camera and tractor functions
again before proceeding. Move tractor forward so the rear of the tractor and the cable
connections are fully inside the pipe. The use of guide poles with a hook on the end
will help to keep the tractor stable as it enters the pipeline.
Install the down hole pole, double roller, and top manhole roller. The use of double
roller and/or single roller is for protecting the cable and allowing it to slide down the
hole without drag on the line.
Remove any slack from the cable and reset the footage counter. It is best to do this by
hand or with cable reel set to low speed.
