Wolff high-speed positioning assistance system available

At the bauma trade fair last year, Wolffkran was the first manufacturer in the crane industry to introduce the electronic assistance system: High-Speed-Positioning-System (HiSPS). It enables loads on the crane hook to be moved virtually sway-free and positioned with millimeter precision. The the patent-pending technology is available for order with Wolffkran’s latest addition, Wolff 6523 Clear.

The connectible HiSPS assistance system operates using two battery-powered sensors on the trolley and hook block of the crane hook. Connected to a control unit in the switch cabinet, it detects the rope’s movements and automatically adjusts the motion and speed of the slewing gear and trolley to it.

“Ultimately, the crane operator controls more than the crane – they control the load with assistance from the system,” said Viktor Mosolf, head of the digitalization department at Wolffkran.

By activating the HiSPS, the load that was already swinging as a result of the crane movement is stopped within seconds, the company said. This can also be used to eliminate heavy wind effects. Since the trolley always assumes its position automatically via the hook block when HiSPS is activated, it prevents the load from being pulled diagonally.

“HiSPS is more than just a digital assistance system and the building block for the autonomous driving crane,” said Dr. Mohamed Abouelezz, head of product management and business development, Wolffkran. “The crane movement and position data that the HiSPS generates can be integrated into the modern digital construction site organization using building information modeling (BIM). With HiSPS, our cranes are ready for the progressive digitalization of the building industry.”
