Vehicle Handling
Because the vehicle is heavy, some handling equipment is recommended with the system installation:
The first of these is a swinging overhead boom for vehicle deployment which must hold the payout
sheave axle at least 2.75 m (9 ft) above ground level. The capacity of the arm needs to be at least 450
kg (½-tonne) at full extension - enough for full vehicle weight plus full winch power. The payout sheave
diameter should be at least 250 mm (10 in) to help prevent tether fatigue.
An electric cable hoisting winch with at least 450 kg (½-tonne) load capacity is necessary to raise and
lower the vehicle. The cable on this hoist needs to be long enough for the deepest expected deployment.
Eddyfi Technologies recommends a dedicated work bench for vehicle configuration and maintenance.
Ideally this is at least 0.75 x 1.5 m (30 x 60 in) and is accessible from both sides. The lower portions of
the bench may be equipped with racks or drawers where tools, spare parts, and fasteners are kept.
Communication
Establish a good channel of communication between the operator and deployment personnel: whether
this is a system of signals, PA system or audio headsets. Good communication can avoid accidents,
damage to the equipment, and promotes efficiency and productivity. The person deploying the vehicle
and watching the tether must be able to quickly tell the operator to stop the vehicle when something goes
wrong. Because he is situated in the office-like van, the operator is often provided with a CCTV system
or view port so he can see directly what is happening with tether payout. It is best practice for the
operator never to turn on power or initiate movement without first communicating with the vehicle handler.
Personnel Requirement
A typical pipe inspection van operation usually requires two people for operations:
•
Console Operator:
This person is responsible for driving the vehicle, watching the pipe and
making comments about the location and pipe condition. It is also the o
perator’s responsibility to
assess whether a pipe is in the appropriate condition for safe passage of the vehicle or if there is
a risk of getting stuck. The operator may also assist in general site setup (cones, warning signs,
etc.), vehicle maintenance and configuration.
•
Deployment / Tether Handler / Field Maintenance:
This person has several tasks including:
o
Configuring the vehicle for the current pipe
o
Lowering the vehicle in and out of the manhole
o
Watching the tether as the vehicle enters and exits the pipe
o
Operating the winch and winding the tether during recovery
