1. General Data AT4
The AT4 carriage is especially designed for the Spierings SK488 folding crane. Extra attention is paid to a smooth
and c omfortable transp ort to the work site. The crane is s uited for driving on public r oads, full y 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 SK488 with the AT4 carriage. The dimensions given are the
overall dimensions, axle bases and turning circle.
Picture 1-1
Measurements:
• Len gth: 15,8m
• W idth: 2,8m
• Heig ht: 4m
Drive unit:
• 12,6 litre DAF-diesel engine with turbo compressor and intercooler (type XE 315).
• ZF gearbox with sixteen gears forward and two gears reverse.
• STEYR high/low shift, transfer case, with high speed (road) and low speed (off the road) transmission.
• Electronic accelerator "E-gas” with speed control.
• Four Ginaf axles, where axle two, three and four are driven.

MANUAL SPIERINGS TRUCK AT4
AT4-EN-050819.doc 1-2
Steering:
• Axle 1, 2 en 4 are steered.
• Mechanically coupled steering, where axle four is steered in the opposite direction of axle one and two,
realizing a small turning circle.
• As option, axle 4 can be mechanically uncoupled and manually steered in the same steering direction as axle
1 and 2 using a joystick. When axle 3 is lifted, sideway driving is possible.
• Hydraulically powered steering system.
• Fitted with an emergency steering pump, so when the main steering pump malfunctions, the truck remains
steer able 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:
• H ydro-pneumatic suspension.
• The suspension can be blocked (e.g. when driving with erected tower.)
Braking system:
• Pneumatic brakes with anti-blocking system (ABS).
4-point outrigger system:
• wide support base = 6,9 m x 6,85 m
• Narrow support base = 6,9 m x 5,15 m
Further data:
• Maximum speed limit to 85 km/h
• Minimum speed at 1250 rpm: 1,9 km/h (is 32 m/min)
• Truck weight including superstructure: 48.000 kg
• De axle load is 12.000 kg per axle

MANUAL SPIERINGS TRUCK AT4
AT4-EN-050819.doc 1-3
Identification:
• Engine number: Left-hand on the engine block above the fuel pump.
Vehicle identification 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. (Picture 1-3)
