Scorpion

Increasing the lifting capacity of davit cranes to 3 tons

Scorpion is the economic as well as effective solution to having the davit cranes lifting 3 tons. It is easily transferred on the CTV with the personnel and mounted onto the special designed davit cranes increasing their lifting capacity to 3 tons, typically from a lifting capacity of 1 ton.

There is typically no need for a crane operator license for everyone at the wind farm, but only for those using Scorpion and it has a substantial economic impact, a considerable amount of cost-effectiveness shows in the crane design itself and with such, the lower WLL with a smaller motor, gear, wire, brake, wire drum, inverters and more. The general replacement costs for smaller components is at a lowered expense – such is the maintenance and exchange of expensive components during their lifetime.

And as one Scorpion per wind farm is sufficient, the procurement costs are substantially lower compared with procuring larger cranes with an individual lifting capacity of 3 tons; especially as this is rarely needed.
