Stahl CraneSystems presents a wire rope hoist specifically for the SWL range from   20 – 32 tonnes in the form of the newly designed ASR 7. It thus bridges the gap between the SH wire rope hoist lifting loads up to 25 tonnes and the AS 7, which can only exploit its full potential with heavier loads. With the ASR 7, Stahl CraneSystems now covers the medium SWL range with a new product which is arousing keen interest from crane builders thanks to its excellent price – performance ratio.

The AS 7, successful for many years, forms the basis for the ASR 7. The differences are seen in the details: due to its lower SWL and in some cases lower classification, smaller motors are used on the ASR 7. The rope drive has been modified accordingly: a 20 mm rope is sufficient for the ASR 7’s lighter loads, instead of a 25 mm rope. This results in a greater height of lift with the same drum length, for example 10 instead of 7 m with the shortest drum length L1. The bottom hook block and return sheave have been adapted to the thinner rope. This results in a price saving of around 25 per cent compared with an AS 7 with double rail crab of the same dimensions. However customers do not have to do without high-quality accessories. For the first time on the AS 7 series,   the load is measured at the rope anchorage as standard. This permits the load to be measured precisely during lifting and lowering and to be shown on a display. 

As a standard hoist, the ASR 7 can also be ordered with the CraneGuide. Depending on application, it is available as stationary hoist or with double rail crab. The new wire rope hoist can also be supplied as an ASRF with a frequency-controlled motor for smooth hoisting and stepless speeds.
