Dando TERRIER Mk 1, Operating And Maintenance Manual, Page: 8 / 276

b. Before travelling, checks should be made to all vehicles for road worthiness,
giving special attention to lights, indicators, screen wipers, registration plates,
brakes, brake lights, steering, security of loads, particularly overhanging
loads, tyre pressure and wear and lack of mud before proceeding onto a
public highway.
c. It is important that checks are made of the coupling and/or hitching of the
drilling rig to any towing vehicle.
d. Where required, long vehicle signs, caution or towing boards should be
securely attached.
e. When towing equipment, correct towing speeds, reversing and manoeuvring
procedures should be observed and assistance obtained where necessary.
Due regard should be paid to road conditions and visibility at all times. Care
should be taken when towing in icy conditions as “jack-knifing” can occur.
The safe towing speed should not be exceeded as there is a risk that
“snaking” may suddenly develop, which may cause the trailer to lose a wheel.
f. Consideration should be given to other road users who may become
impatient and take risks - it is advisable to pull into the side occasionally to let
them pass.
g Where wide, long or heavy loads are to be moved it is advisable to have all
lights on for road travel, even in broad daylight.
h. On arrival at the site, ground conditions should be checked before driving in,
and a watch kept for temporary overhead obstructions.
i. If necessary, an assistant should be used to control traffic if safety dictates.
j. Passengers should not be carried on or around the machine.
k. The driver of the vehicle should check for all round visibility before
commencing any manoeuvre, especially reversing. If necessary, an
assistant should be used to signal. The presence of an assistant does not
relieve the driver of his responsibility, so he should constantly check the rear
view in his mirror, and by direct sight.
l. When manoeuvring vehicles, due regard should be paid to soft ground,
potholes, gradients, slippery grass and mud, and overhead cables. Special
care should be taken when crossing dykes with improvised bridges. At all
times, personnel should keep well clear of moving vehicles in case they
overturn. Where winches must be used, a watch should be kept for flying
ground anchors and rope failures.
m. Loading and un-loading the plant should only be carried out on firm level
ground.
n. The vehicle’s driver should act as assistant during loading and un-loading
operations. Signals should be agreed beforehand and standard procedures
followed.
