1. General data AT4

The AT4 carriage is especially designed for the Spierings SK477 folding crane. Extra attention is paid to a smooth

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 an especially rigid structure to create a good crane support.

In Picture 1-1 you will find the measurements of the SK477 with the AT4 carriage. The dimensions given are the

overall dimensions, axle bases and turning circle.

Picture 1-1

Drive unit:

•11.63 litres DAF diesel engine with turbo compressor and intercooler (type WS 268L).

•ZF gearbox with 16 gears forward and two gears reverse.

•STEYR high/low gear shift, transfer case, with high speed (road) and low speed (off the road) transmission.

•Four Ginaf axles, where axles two, three and four are driven.

USER MANUAL SPIERINGS TRUCK AT4

AT4-EN-041115.doc

1-2

Steering:

•Axles one, two and four are steered.

•Mechanically coupled steering, where axle four is steered in the opposite direction of axle one and two,

realizing a small turning circle.

•Hydraulically powered 1-circuit steering system.

•Hydraulically powered 2-circuit steering system (serialno. 47752 and higher)

•Fitted with an emergency steering pump, so when the main steering pump malfunctions, the truck remains

steerable until it is at a standstill.

•Provisions for driving off the road:

•Axle height adjustable

- high/low gear shift transfer case can be put in low gear for driving off the road

- longitudinal and transverse differentials can be locked.

Suspension:

•Hydro-pneumatic suspension

•The suspension can be blocked (e.g. when driving with erected tower).

Braking system:

•Pneumatic brakes.

4-point outrigger system:

•Wide support base : 6.55 m x 6.15 m

•Narrow support base : 6.55 m x 5.1 m

Power supply:

The superstructure can be supplied with power in two different ways:

•External power-supply 40 kVA during erecting and folding, 40 kVA during operation.

•The truck built-in Leroy Somer 70 kVA generator for power supply to the superstructure when (sufficient)

external power is lacking.

Further data:

•Maximum speed limited to 85 km/h.

•Minimum speed at 1000 rpm: 1.8 km/h (is 30 m/min) .

•Truck weight including superstructure and counterweight 48,000 kg.

•The axle load is 12,000 kg per axle.

Identification:

-Engine number: On top of the engine block.

-Carriage frame number: On the identification plate 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).
