The SK597-AT4 eLift is the newest generation of the Spierings hydraulic mobile tower crane with four axles. This crane can operate 100% emission free.
The four-part jib of the SK597-AT4 provides a 48-metre working radius with a compact vehicle length. The maximum lifting height is 27.8 metres with the jib in the horizontal position, and no less than 58.1 metres with the jib at a 45-degree upward angle.
The SK597-AT4 eLift has the very latest technology when it comes to cranes. The crane can lift its maximum load of 7000 kg without using additional ballast blocks.
Full electric & hybrid mode
The Zero-Emission eLift system has two operating modes; electrical mode and hybrid mode. Both modes have an efficient first line energy source, which can be chosen for the grid connection or diesel engine. The PowerPack® battery technology absorps the peaks in energy usage and will be charged when energy is unused. By using the electric mode you operate the crane 100% emission free on a silent sound level without any limitations in usage.
To operate the crane in electric mode it needs to be connected to a 32A grid connection that’s quite often available at most job sites. The system is using between 11A and 25A which can be pre-set at the display, so there is still energy left for other purposes.
A small 55kW 3-cylinder diesel engine with the newest Stage V emission certification is the main energy source during hybrid mode. The unused energy of the diesel engine is used to recharge the battery of the PowerPack®, so it can be used for peak absorption.
16a or 32a grid connection
Operate the SK597-AT4 eLift or SK1265-AT6 eLift full electric by a grid connection between 11A and 32A which can be pre-set at the display, so there still can be energy left for other equipment on site.
PowerPack® battery technology
The PowerPack® battery technology absorbs the peaks in energy usage and will be charged when energy requirement for the crane is low.
Free of noise & emission
Operate the eLift crane completely free of noise while operating in ‘electric mode’. Especially during city jobs and night jobs it’s a great advantage to work noise- and emission free.
