SPIERINGS AT5 User manual

MANUAL SPIERINGS TRUCK AT5
AT5-UK-030626 01-12-09 I
Introduction
This manual is put together to provide the user of the Spierings truck, model AT5, with information about this
truck's construction, operation and maintenance.
The driver must have a driving license for driving a heavy truck and have sufficient technical knowledge.
The AT5 truck is built to serve as carriage for the Spierings folding crane, model SK598. For operation, technical
data and maintenance of this folding crane we refer to the subjoined manual.
Because the AT5 is provided with five axles, of which 3 axles are steered, excellent mobility is guaranteed on the
work site as well as on the road. The axles are hydro-pneumatically suspended, whereas the height can be
adjusted and/or blocked. Three axles are driven by a 12.6 litres DAF diesel engine and a gearbox with sixteen
gears forward and two gears reverse. After the gearbox is a high/low gear shift (transfer case), which has two
different gears and a neutral. A gear for driving on the road and a gear for driving off the road. Neutral serves for
the generator drive by the high/low gear shift PTO.
Furthermore, there is a hydraulic system for operating the crane's outrigger system and, when the crane is not
equipped with a separate engine on the upper frame, the truck has a 400 Volt generator to provide the crane with
the necessary power.
The following items are dealt with in this manual.
General data. In this chapter you will find a description of the measurements and technical specifications.
Location and explanation of controls.
Operating the AT5. This chapter gives you instructions for optimal use of the truck.
Maintenance of the AT5, maintenance schedules as well as explanation of the maintenance work to be
carried out. You will also find a maintenance plan containing the specification of the used parts and
lubricants.
Specification of drive line and steering system parts
Explanation of the hydraulic, pneumatic and electrical system.
You will find the outline drawings and diagrams referred to at the back of this manual in the enclosures.
Due to the continuous product development at Spierings Kranen the descriptions and pictures may not be all together similar to the condition on your vehicle.

1a. Truck cab
Besides driving the crane, with the controls in the truck cab you can support the crane on outriggers, adjust the
carriage axle height and switch the generator on and off.
2a. Hydraulic oil tank / battery box
On this side of the truck, under the engine cowling, you will find the
hydraulic oil tank (See Picture 2-2, nr.3) and air cleaner (nr.2).
Behind the oil tank, you’ll find the battery-box (nr.1).
2. Battery switch
On the left side behind the cab, you’ll find the battery switch.
Picture 2-2
3. Toolbox at the rear / power box
You will find the power-box in this storage box by opening the right sliding door.
With the selector switch on the power-box, the power supply for the crane is selected. Either an external power
supply can be connected to this power box, or the built-in generator supplies the power. Power can also be
branched off for accessory equipment.
4. Steel support plates
To obtain a solid support base on a week ground, support plates have to be used. In this place, 4 steel support
plates are stored.
5. Storage room support plates
Under the truck cab, there are 2 storages with 2 synthetic support plates each (or 3 each in combination with steel
support frames).
These synthetic support plates have to be used to rig up the crane on narrow support base, after which the steel
support plates can be placed, using the crane. After placing the steel support plates you can outrigger to wide
support base.
6. Outriggers
At both sides of the truck there are 2 extending outrigger beams, and to each beam a hydraulically operated
outrigger (See Picture 2-3). These outriggers provide stability during hoisting operation. The outrigger beams
have an antiskid coating to prevent skidding. The outrigger pad holders can be used to facilitate stepping on the
outrigger beam.
With a separate (remote) control box the outriggers can be radio controlled. On the rear outrigger beams are
levels to check if the crane set-up is level.

AT5-UK-030626 01-12-09 2-3
Picture 2-3
7. Fuel tank
The fuel tank capacity is 600 litres.
8. Bumper
The crane has a standard bumper at the rear. When the bumper is folded up, the towing hook can be used (refer
“Driving with a trailer”).
9. Jib turning pipe
Through a hole in the deck you can reach the jib turning pipe. This pipe is used to swing the jib in front of the
tower during assembly and back when dismantling the crane.
10. Work lamps
To the rear of the cab and truck are mounted work lamps, which can be
switched on/off from the cab.
By unscrewing the knob, the lamp support can be moved to the left and right
(See Picture 2-4).
Picture 2-4
11. Truck ladders
To facilitate getting on the truck three ladders are mounted. Two ladders
are mounted between axle 2 and 3. To pull you up, brackets are mounted
on the deck.
The third ladder is mounted on the deck on the side of the electrical
cabinet of the crane. Pick up the free end of the ladder so the pin comes
out of the deck (See Picture 2-5) and swing the ladder outside the frame.
When swinging back the ladder, make sure the pin returns in the hole.

Safety belts
The seats are fitted with safety belts. Driver and co-driver must wear them when driving. Do not modify the belt or
its attachment by yourself. Regularly check its operation by jerking the belt from its winding mechanism. The belt
must lock when doing this. Have the locking device repaired or replaced when it does not function properly. When
the belt was heavily loaded during a collision, it must be completely replaced, even if it looks like there is nothing
wrong with it.
Storage room
In the middle of the cab ceiling is a storage compartment. It has a lockable lid at the driver's side and at the side
of the co-driver. There is another storage compartment at the co-driver's side in the dashboard (See Picture 2-7,
A).
Sun blind
To prevent sunlight from blinding you, a sun blind is mounted above the windscreen for the driver and the co-
driver. Pull down the blind with the joggle in the middle of the blind. The blind will remain in the desired position.
Push the button on the side of the blind to roll it up.
Fuse box
The fuse box is at the co-driver's side in the centre console (See Picture 2-7, B). You will find the fuses listed in
the enclosures.

20. Indicator lamp max. pressure outrigger-/suspension system
This lamp goes on and a buzzer sounds at the rear outriggers as soon as the pressure in the
outrigger/suspension system becomes too high. This may happen when the outriggers, the axles or
the outrigger beams are fully in or out, or because there is an obstacle in the way when extending
the outrigger beams.
During leveling operation and when moving the axles up or down, this light could also go on. This
does not present a problem.
If there’s no action of the outrigger-/suspension system, the lighting of this lamp means, that an
error is occurred.

With the speed control you can keep your current speed constant without using the accelerator
pedal. The speed control doesn’t work at a speed under 30 km/h.
Set: Switch on and adjusting the speed control.
If you are at the desired speed, move the lever to “set”. The speed control will
hold on to this speed.
If the speed control is already switched on, the speed will increase by keeping
the lever to “set”. If the speed control is switched on, you still can accelerate
by using the accelerator pedal.
When the switch “increased rpm” is switched on, you can adjust the rpm of the
engine with this lever.

By moving the lever to setyou can decrease the speed. Keep the lever down
until you reach the desired speed.
Memo: When you brake or press the clutch, the speed control will switch off. By
moving the lever to “memo”, the speed control will switch on again. It will adjust
the speed back to the last saved speed (if speed >30 km/h). The shifted gear
has to be the same as the last time you set the speed control.
The memory will reset when you shut down the engine.

speed control will also switch off by braking, pressing the clutch and in case of
an accident.
Tip-up,Tip-down:
When you move the lever briefly to “set” or “set”, you will increase or decrease the speed with
one km/h. The difference between the current speed and the new adjusted speed can not be more
than 5 km/h.
34. Voltmeter batteries
On this meter you can read the battery condition. The meter must be in the middle (approx. 24 Volt)
35. Oil-pressure gauge lubrication circuit
When starting this gauge will read approx. 5 bar. As soon as the oil is warm approx. 3 bar.
36. Retarder (Optional)
Refer to “Slowing down using the retarder”
37. Lever parking brake
By pulling this lever. backwards the parking brake is engaged. Pulling out the knob and pushing the lever
forwards will release the parking brake. To release the parking brake, the pressure must be at least 5.5 bar.
38. Speedometer/tachograph
The truck is equipped with a VDO tachograph. On this device you can read the driving speed and the
number of kilometres driven. The tachograph also contains a clock (1). This clock drives a diagram disc. On
this disc the activities of the driver are written by means of scribers. The disc can be replaced by opening
slot 2 (See Picture 2-9). Never leave a disc in the tachograph for longer than 24 hrs (else it would overwrite
itself). In case there is no disc in the tachograph, indicator lamp 3 will light up.
By means of switches 4 and 5 the drivers' activities can be shown. Indicator lamp 3 goes on as soon as the
driving speed exceeds 80 km/h. When at a certain speed button 6 is pressed, exceeding this speed will light
up the indicator lamp. However, when the ignition is switched off, the indicator lamp will be set to 80 km/h.
The clock may be set to the correct time by operating wheel A.
For more details on how to use the tachograph we refer to the tachograph manual (in the glove
compartment).
