SECTION 2. SAFETY

2.1 For safety reasons the driver/operator/user should carry out all operations as stated in the user manual

or in the additions to it.

2.2 If more stringent safety demands are locally placed on the truck/crane than specified in the Spierings

truck user manual or additions to it, these more stringent requirements must be strictly complied with. If

not, all warranty will expire and the manufacturer will not be liable for any damage or costs.

2.3 The Spierings truck manufacturer points out explicitly, that the driver/operator/user and local personnel

should not enter the cranes/trucks danger zone. If, for any reason or cause, an unexpected situation

occurs during operation one should contact the technical department or Spierings Service department

1. General data AT3

The AT3 carriage is especially designed for the Spierings SK377 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 SK377 with the AT3 carriage. The dimensions given are the

overall dimensions, axle bases and turning circle.

Picture 1-1

Measurements:

•Length: 13,5m

•Width: 2,6m

•Height: 4m

Drive unit:

•9.6 litres DAF diesel engine with turbo compressor and intercooler (type PE 265C).

•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.

•Three Ginaf axles, where axles one and three are driven.

MANUAL SPIERINGS TRUCK AT3

AT3-EN-040930 verbeterde versie.docx

1-2

Steering:

•All axles are steered.

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

realizing a small turning circle.

•Hydraulically powered 2-circuit steering system.

•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

•Electronic gas pedal "ESC” with speed control.

Suspension:

•Hydro-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: 6,9m x 6,4m

•Narrow support base: 6,9m x 4,8m

Power supply:

When there is no separate diesel engine on the superstructure, the crane can be supplied with power in two

different ways:

•External construction power-supply 40 kVA during rigging up/rigging down, 40 kVA during operation.

•The truck built-in Leroy Somer 70 kVA generator for power supply to the crane 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 crane 36,000 kg

•The axle load is 12,000 kg per axle

MANUAL SPIERINGS TRUCK AT3

AT3-EN-040930 verbeterde versie.docx

Identification numbers:

•Engine number: left-hand front on the engine block below the cylinder head rim.

•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 (see Picture 1-3)
