any guarantee claim as well as any liability for damage, consequential damage and future damage, by any
reason and for no matter what.
1.3. Operating the Spierings truck is only permitted by people, who have the relevant expertise and a valid
driving license for driving a heavy truck, and who are physically and mentally capable of properly carrying
out the work involved.
1.4. In case of the additions to the manual, the user/operator/driver of the Spierings truck must be notified
thereof immediately, and the additions must be added to the manual.
ARTICLE 2. Safety
2.1. For safety reasons, the user/operator/driver must strictly comply with the instructions in the manual and
possible additions thereto.
2.2. If at any work site of the Spierings truck/crane the safety rules and regulations are more strict than those
laid down in the manual, or possible additions thereto, these stricter rules are to be complied with under
penalty of expiry of the guarantee and with exclusion of every liability.
2.3. The Spierings truck manufacturer explicitly warns the user/operator/driver and/or bystanders, to stay out of
the Spierings truck/crane's danger zone.
If any unexpected situation, by whatever cause, occurs during use and/or operation of the Spierings truck,
please contact your technical department or Spierings Service immediately.

1. General Data AT7
The AT7 carriage is especially designed for the Spierings SK2400 folding crane. Extra attention is paid to a safe
and comfortable transport to the work site. The crane is suited for driving on public roads, fully equipped with
counterweight and tools. The chassis is a specially rigid structure to create a good crane support.
Picture 1-1 shows the measurements of the SK2400 with the AT7-carriage. The measurements given are the
overall dimensions, axle bases and turning circle.
Picture 1-1
Drive Line:
•12.9 litre DAF-diesel engine with turbo compressor and intercooler (model: XM375S1).
•ZF-TC Tronic automatic gearbox with retarder and torque converter; twelve forward gears and 2 reverse
gears (model: ZF12TC2740).
•STEYR transfer case, with high speed (road) and low speed (off the road) transmission (model:
VG2701/400).
•Electronic accelerator "E-gas” with speed control.
•7 Kessler & Co axles, of which axles 1, 3, 4 and 7 are driven.

AT7-EN-070103 aangepast 26-7-2018.docx

Steering:
With regard to the steering, we distinguish between road and off the road steering.
•Road steering: Axles 1 to 3 are mechanically steered by means of the steering wheel, axle 4 remains rigid
and, depending on the driving speed, axle 5 steers along in opposite direction up to 30 km/h, axles 6 and 7
up to 50 km/h respectively.
Off-the-road steering: these special steering programs are only available in off-the-road mode.
•“Small turning circle”: This steering program enables an extra small turning circle.
•“Manual”: this program enables you to control the steering movement of axle 7. Axles 4 to 6 steer along
proportionally.
•“Crab steering: all 7 axles steer in the same direction.
•“Wall steering”: Program to drive away from an object with minimal swing of the truck's rear end.
The 2-circuit steering system is hydraulically powered by means of a 2-circuit steering gear housing and auxiliary
cylinders.
The steering system is fitted with an emergency steering pump, so in case of main control pump malfunction or
diesel engine break-down, the truck remains steerable until it stands still.
•Provisions for driving off the road:
- Adjustable axle height
- Transfer case with off-the-road gear
- Longitudinal and transverse differentials can be locked.
- All axles participate in the steering process.
Suspension:
•Hydropneumatic suspension
•Possibility to block the suspension.
Braking System:
•Pneumatically operated brakes
4-point Outrigger System
•Wide (full support base): 7.95 m x 7.63 m
•Narrow (reduced support base): 7.95 m x 5.72 m
Further Data:
•Maximum speed limited to 83 km/h
•Minimum speed at 1.000 rpm: 1.85 km/h (is 30.8 m/min)
•Truck weight including superstructure approx. 84,000 kg.
•The axle load is 12,000 kg per axle.

Identification:
•Engine number: on the valve cover or on the water pump.
•Carriage frame number: on the identification shield in the co-driver's leg-room (see Picture 1-2) and stamped
in the right frame girder in front of the first axle. (see Picture 1-3).

2. Operation
2.1. Introduction to the Truck
Picture 2-1
1. Bumper
The bumper, equipped with lighting fixture, can be folded up to hitch on a trailer.
2. Truck Cab
In addition to driving the crane, the control panel in the truck cab can be used to operate the outrigger system and
to adjust the axles' height.
3. Work Lamps
Work lamps are found at the rear of the engine cowling
and at the rear of the truck, both at the left and right-
hand side, which can be operated in the cab.
By loosening the screw (A) at the bracket, the lamp can
be moved sideways. (Picture 2-2).
Picture 2-2

MANUAL SPIERINGS TRUCK AT7

4. Left-hand Engine Cowling
At this side under the engine cowling, the following
parts are found:
1. Control box
2. Grease container for automatic lubrication
system
3. Auxiliary steps
4. Oil filling pipe
Picture 2-3
5. 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 keep the machine stable during hoisting operations. The outrigger beams have
an antiskid coating (5) to prevent slipping. 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. The level position of the crane can be
checked by means of the levels.
Furthermore, the crane is equipped with a standard automatic outrigger control program.

6. Right-hand Engine Cowling
At the right-hand side of the truck under the engine
cowling, the following parts are found:
1. Air cleaner
2. Combined cooler (intercooler/radiator/oil cooler)
with hydraulically driven fan.
3. Soundproof side
Picture 2-5
7. Fuel Tank
The fuel tank is integrated in the frame at the rear of the truck. The tank capacity is 725 litres and can be filled
through a filler neck at the rear, right-hand side of the truck. (Picture 2-6).
Picture 2-6
8. AdBlue Tank
The filler neck on the AdBlue tank is at the right-hand side in the middle of the truck. The total capacity of this tank
is 75 litres.

9. Outrigger Plates
Directly behind the truck cab 4 steel outrigger plates in all can be carried. They can be put in place by means of a
hoisting arm mounted at the crane's outer tower.
2.2. Truck Cab
2.2.1. Getting in
Use the step under the door.
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 by means of 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 optimal 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 2-8).
A) Back adjustment
B) Lumbar support adjustment (push = inflate and pull = deflate)
C) Height adjustment (pulling the handle = up and pushing it = down)
D) Tilting the seat
E) Handle rapid lowering
F) Chair seat adjustment
Picture 2-8
2.2.5. Seat Belts
The seats are fitted with seat 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 lock repaired or replaced, if 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.
