Heavy-duty manipulators

06 April 2021

Dango & Dienenthal has received an order from Chinese thyssenkrupp rothe erde (Xuzhou) Ring Mill Co. (XREM) to supply two manipulators for a new ring rolling facility in Xuzhou.

The heavy-duty robot ordered by XREM will be one of the most powerful of its kind in the world.

XREM is going to produce seamlessly rolled rings for large rolling-element bearings on its new mill. The production line will include several chamber-type forging furnaces, an open-die forging press that will produce the ring blanks, and a ring-rolling mill facility incorporating several intermediate reheating furnaces for the rolling stock, and, finally, a heat treatment facility. 

The two machines to be supplied by Dango & Dienenthal will perform all handling operations for the blanks and the rings – from the acceptance of the cut forging ingots up to and including the delivery of the finished rings to the heat treatment facility.

The Diesel-powered machine will be designed also for a payload of 150 kN. Its gripping tongs will be able to handle ring diameters of up to 2,600 mm. Both machines will be ready for delivery to XREM in early 2022.
