In summer 2016, STAHL CraneSystems produced 18 special SH 60 hoists with special articulated trolleys and new SFR 35 friction wheel drive on behalf of STEULER Anlagenbau. The hoists are intended for use in an automated circular rail tunnel pickling plant for wire coils near Shanghai.

The surface treatment plant consists of a pre-treatment stage with potassium permanganate/sodium hydroxide, several pickling stages, zinc phosphating plus borax, soap or lime coating with the necessary rinsing stages. Transport through the plant is carried out using the special hoists produced by STAHL CraneSystems, driven by the SFR 35 friction wheel drive. The trolleys and hoists are controlled via PLC and WiFi plus other position systems used by STEULER. The travel speed can be adjusted between 2.0 and 20.0 m/min. using a frequency converter. By using articulated trolleys, it is possible to travel through a 4,000 mm curve radius. The VA protective plates mounted underneath the wire rope hoists and friction wheel drives protect the equipment against the environmental influences of the plant and pickling tanks.
