Pre / Post Operations Check
A Pre / Post Operations check list is included in Annex B. The check list may be photocopied for regular
use. Operators are encouraged to use the check list to help prevent error and maximize equipment
reliability to ensure a successful mission.
Note:
Ensuring the Versatrax 300
™ is always stored in good working condition will minimize deployment
time for future inspections.
Vehicle Deployment
The VT300 vehicle must be deployed into a manhole using a cable hoist. While the tether can carry the
weight of the vehicle, unnecessary loading of the termination is discouraged.
1. Check that the vehicle is fully configured and ready for the mission (see Pre / Post Operations
Check above).
2. Hook the cable hoist onto the shackle between the Kellems grip and the tow cable.
3. Attach a tag line to the yellow eye-hook at the front of the vehicle
– in such a way that the line can
be disengaged from the surface once the vehicle is deployed. The easiest way to do this is to
thread the line down and back up so you have both ends of the line in your hand
– no knot
involved.
4. Hoist the vehicle overtop the manhole, using the tag line to keep swing and rotation under control.
5. Lower the vehicle until the front end is near the floor. Pull up on the tag line to tilt the front section
up so that the tracks are the first to touch the bottom. The center hinge of the vehicle can bend
90° upward to negotiate into the pipe.
6. After touchdown of the front section, remove the tag line.
7. Begin driving the vehicle slowly forward and lower the rest of the vehicle behind.
8. When the vehicle is fully seated in the pipe put a down-hole sheave in place to protect the tether
around the bottom corner.
9. The vehicle is now ready for its mission through the pipe.
Vehicle Recovery
The VT300 vehicle is designed for quick, efficient recovery by using the winch to tow it out of the pipe.
Just how quickly recovery can proceed will depend on the condition of the pipe and how far the vehicle
has traveled. Some factors may slow down recovery, such as distant travel into the pipe, bends and
corners.
1. Begin retrieval by activating the
“Start Retrieval” function in the user interface. This will disengage
the track drive clutches and lock out the forward controls; you will be able to control the tracks in
reverse but not forward.
2. If the vehicle has gone a long distance down the pipe it may require an excessive force on the
tether from the winch to tow the vehicle. To prevent this, begin by driving the vehicle in reverse,
hence taking the load of the vehicle off the tether.
3. Carefully watch the rear facing camera whenever the vehicle is in reverse. Ensure the tether is
towed from behind the vehicle. Accidentally driving over the tether runs a high risk of breaking the
fibers and even jamming the vehicle.
