The SK597-AT4 is the fourth and newest generation of the Spierings hydraulic mobile tower crane with four axles. The Spierings crane has been supplied more than 300 times already. The four-part jib of the SK597-AT4 provides a 48 meter radius, together with a compact vehicle length. The maximum lifting height is 27,8 meters with a jib in horizontal position, and a whopping 58.1 meters with the jib at a 45 degree upward angle. The SK597-AT4 has the very latest technology when it comes to cranes. It can lift its maximum load of 7000 kg without using the additional ballast blocks and the assembly time is also unbeatably fast — just four minutes for the outrigger support base and eight minutes to fold out the crane.
The truck cabin of the SK597-AT4 is completely renewed and offers an optimal comfort. Users benefit from features including an automatic ZF AS-tronic transmission, Bluetooth communication, truck navigation system, air conditioning, a high-quality sound system, and reverse drive and side view camera(s) with a monitor in the cab. Moreover, it’s the first Spierings cranes equipped with standard disc brakes.

Thanks to the hydropneumatic suspension system, high and low gears and several control programmes, the crane is extremely manoeuvrable on both construction sites and public roads. This enables the Spierings crane to travel longer distances without any problems, so it can be used in a greater area. Numerous refinements mean that the SK597-AT4 design is of an extremely high level of quality, and the dosability and enhancement of the hydraulic operation is unrivalled, allowing precise and fast movements of the crane. The superstructure diesel engine drives three hydraulic pumps for crane functions, with no interference from inefficient components.
If desired, the crane can be equipped with 4 steel pads 2000x900mm including an auxiliary crane arm for placing the steel pads.
