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

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.

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).
