WK3 is an improvement on WK1 from Carl Stahl; the counterweight offers ability to handle weights up to 1000 kg. It is versatile and can be fitted with standard hoists and other handling devices of any make. The standard crane is compact and can be transported around using a forklift or overhead crane. Optional attachments such as mechanical/hydraulic wheels can be provided to further improve the mobility. The extension cord supplied for electrical connection renders this a turnkey solution.
