Introduction
This manual is put together to provide the user of the Spierings truck, model AT5, with information about this
truck's construction, operation and maintenance.
The driver must have a driving license for driving a heavy truck and have sufficient technical knowledge.
The AT5 truck is built to serve as carriage for the Spierings folding crane, model SK598. For operation, technical
data and maintenance of this folding crane we refer to the subjoined manual.
Because the AT5 is provided with five axles, of which 3 axles are steered, excellent mobility is guaranteed on the
work site as well as on the road. The axles are hydro-pneumatically suspended, whereas the height can be
adjusted and/or blocked. Three axles are driven by a 12.6 litres DAF diesel engine and a gearbox with sixteen
gears forward and two gears reverse. After the gearbox is a high/low gear shift (transfer case), which has two
different gears and a neutral. A gear for driving on the road and a gear for driving off the road. Neutral serves for
the generator drive by the high/low gear shift PTO.
Furthermore, there is a hydraulic system for operating the crane's outrigger system and, when the crane is not
equipped with a separate engine on the upper frame, the truck has a 400 Volt generator to provide the crane with
the necessary power.
The following items are dealt with in this manual.
