Towing
If the vehicle needs to be towed, the state of the vehicle must be determined:
If the diesel engine, the service brake and the steering system function, the vehicle can be towed
by a heavy tow truck or salvage truck;
If the diesel engine, the service brake and the steering system do not function properly,
the vehicle must be towed by a special salvage truck.
The distance over which the vehicle must be towed, is relevant.
There is a difference between:
Towing the vehicle over a short distance (out of the dangerous area);
Long(er) distances (> 100 m).
In most cases, proper functioning of the service brake and the steering system is depending on the
diesel engine.
If the diesel engine is working properly:
The air circuit remains under pressure, so while driving the brake can be used and the parking
brake can be released;
The power-assisted steering remains active.
CAUTION!
Before towing of the vehicle, contact Spierings Mobile Cranes;
The indicated instructions are just meant to help the driver in his preparations
before towing. Spierings Mobile Cranes is NOT responsible for missing
instructions or unforeseen situations, which may occur while towing;
Depending on the cause of towing, a balanced choice of the measures to be
taken must be made;
Towing and the measures before towing may only be carried out by skilled,
qualified and trained personnel;
If towing is necessary, take into account the maximum length of the vehicle
combination (the towing and towed vehicle, including towing bar);
Towing is only allowed if the crane is in
transport position
;
The shunting coupler is designed for a maximum pulling capacity of
10 tonnes;
Tow the vehicle only with a an appropriate towing bar;
Tow the vehicle with the lowest possible speed, maximum 20 kph (12.5 mph).
Gradually accelerate the vehicle combination to prevent damage on the
vehicle;
Starting the diesel engine by towing is not possible due to the automatic
gearbox in the drive line.
