1. General data AT6
The AT6-truck is especially designed for the Spierings SK1265 folding crane. Extra attention was paid to a
smooth and comfortable transport to the work site. The crane is suitable for driving on public roads fully fitted with
counterweight and tools. The chassis is an especially rigid structure to create a good crane support.
Picture 1-1 shows the measurements of the SK1265 with AT6-carriage. It states the overall dimensions, axles
distances and turning circle.
Picture 1-1
Measurements
•length: 15,5m
•Width: 3m
•Height: 4m
Drive system
•12.6 ltrs DAF diesel engine with turbo compressor and intercooler (type XE-390C1).
•ZF automatic transmission retarder; sixteen forward gears and one reverse gear.
•STEYR transfer case with a high (road) and a low (all-terrain) drive.
•Electronic accelerator pedal "E-gas” with speed control.
•Six Kessler & Co axles, where axle one, two, three and six are driven.
Steering:
•Axle 1, 2, 3, 5 and 6 are steered.
•Axle 5 and 6 are steered in opposite direction of axle 1, 2 and 3 to reduce the turning circle.

MANUAL SPIERINGS TRUCK AT6
AT6-EN-061031.doc 1-2
•Axle 5 and 6 can be disengaged. The axles may be steered in the same direction as the 3 front axles either
by means of a steering knob or fully automatic. This way you can drive in crab steering mode.
•The 2-circuit steering system is hydraulically powered by means of a 2-circuit steering gear housing and 3
auxiliary cylinders.
•The steering system is fitted with a emergency steering pump, so in case of a defect in the main steering
pump or stalling of the diesel engine, the truck remains steerable until it stands still.
•Provisions for driving off the road:
- adjustable axle height
- transfer case can be shifted in all-terrain gear
- longitudinal and transverse differentials can be locked
Suspension:
•Hydro-pneumatic suspension.
•Suspension can be blocked.
Brakes:
•Pneumatic operated brakes.
4-point outrigger support:
•Wide: 7.95m x 7.66m
•Narrow: 7.95m x 5.72m
Other data:
•Maximum speed limited to 85 km/h.
•Minimum speed at 1250 rpm: 1.9 km/h (is 32 m/min)
•Truck weight incl. superstructure approx. 72,000 kg
•The axle load is 12,000 kg each axle.
Numbers:
•Engine number: at the left on the engine block above the fuel pump.
•Vehicle identification number: on the ID-plate in the co-driver's legroom (see Picture 1-2) and engraved in the
right-hand frame girder in front of the 1st axle (see Picture 1-3).
Picture 1-2 Picture 1-3

MANUAL SPIERINGS TRUCK AT6
AT6-EN-061031.doc 2-1
2. Operation
2.1. Getting to know the truck
Picture 2-1
1. Bumper
If desired a bumper can be mounted, which enables you to take along an extra sling box or spare wheel. When
the bumper is folded up, the tow hook can be used.
2. Rear and side view cameras
To broaden your view at the rear and right-hand side of the truck cameras are installed. A monitor in the cab
shows the views.
3. Truck cab
Besides driving the crane, with the control panel in the truck cab the crane can be supported on outriggers and
the axle height can be adjusted.
4. Work lamps
At the rear of the engine compartment work lamps are
mounted at the right-hand side as well as at the left-
hand side. They can be operated from the cab.
By loosening knob (A) on the bracket the lamp can be
adjusted further (Picture 2-2).
Picture 2-2

MANUAL SPIERINGS TRUCK AT6
AT6-EN-061031.doc 2-2
5. Left engine cowling
At this side under the engine cowling you will find
the following parts:
1. Electrical cabinet
2. Button box
3. Grease reservoir central lubrication system
4. Ladder
5. Oil top up pipe
Picture 2-3
6. Ladder
Via the ladder at the back of the truck you can mount the truck frame. The ladder inside the left engine cowling
can also be used for this purpose.
Mind your safety.
7. Outriggers
At both sides of the truck there are 2 extending outrigger beams (4), and to each beam a hydraulically operated
outrigger (1). These outriggers provide stability during hoisting operations. The outrigger beams have an antiskid
coating (5) to prevent skidding. The outrigger pad holders (3) can be used to facilitate stepping on the outrigger
beam.
With a separate (remote) control box the outriggers can be radio controlled. Check to make sure the crane is level
by using the levels.
Picture 2-4

MANUAL SPIERINGS TRUCK AT6
AT6-EN-061031.doc 2-3
8. Right engine cowling
Underneath the engine cowling at the right-hand side
of the truck you will find the following parts:
1. Air filter
2. Combined cooler unit (Intercooler/radiator/oil
cooler) with hydraulically driven fans.
3. Noise isolating wall
Picture 2-5
9. Fuel tank
The fuel tank is integrated in the frame at the rear end of the truck. The tank capacity is 600 ltrs and can be filled
through the filler neck at the rear of the truck (Picture 2-6).
Picture 2-6
10. Rear box
The rear box contains both on the left as well as on the right and rear a lockable storage compartment. In the
centre under the outrigger support plates you will find a sling box.
11. Outrigger support plates
On top of the rear box you can store four outrigger support plates. They can be put in operating position by means
of a hoisting arm, which is mounted to the outer tower.

MANUAL SPIERINGS TRUCK AT6
AT6-EN-061031.doc 2-4
2.2. Truck cab
2.2.1. Getting in
Use the step under the door. Make use of the steering wheel to hold on to.
2.2.2. Doors
Turn the handle up to open the door from the inside. The door can only be locked up from the outside. There is an
ashtray on the inside of the door. After opening the ashtray, you push the locking device down to remove the
ashtray from the holder to empty it.
The windows can be operated with the switches on the dashboard.
2.2.3. Wing mirrors
The wing mirrors may be adjusted by hand. Make sure the mirrors are adjusted before driving off, so that you
have satisfactory view. The mirror heating can be switched on with a switch on the control panel.
2.2.4. Seats
The cab has room for the driver and a co-driver. The driver's seat has pneumatic
suspension, the co-driver's seat does not. The seats' position can be adjusted.
This should only be done when the vehicle stands still.
(See Picture 2-7).
A) Back adjustment
B) Lumbar support adjustment (pressing = inflate and pull = deflate)
C) Height adjustment (pulling the handle = up and pushing it = down)
D) Tipping the seat
E) Handle fast lowering
F) Seat adjustment
Picture 2-7
2.2.5. Safety belts
The seats are fitted with safety belts. Driver and co-driver must wear them while 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 lock 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.
2.2.6. 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. Also in the dashboard at co-driver's side you will find a storage compartment.
2.2.7. 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.
