现代化改造

Reliable and safe

In the course of their long service lives, the demands placed on crane systems and crane technology change. New operating procedures, stricter safety requirements as well as high-cost and high-maintenance components present operators with the question of how the value of a system can be maintained and its efficiency increased. Instead of a mere repair or a comprehensive general overhaul, it is often worth considering modernising the system. It is cost-effective because specific replacement of individual components or systems means that many existing elements can continue to be used and the entire installation does not have to be replaced. At the same time, modernisation makes it possible to maintain the productivity of a plant and enhance its safety over the long term with selected adaptations.

From consultation and planning to implementation of modernisation projects, our customers can rely on the know-how and pioneering technology of STAHL CraneSystems.

Modernisations with STAHL CraneSystems

Experts worldwide rely on modernisations with STAHL CraneSystems. Innovative and well-conceived down to the smallest detail, we use our know-how to implement various modernisation projects with the utmost care. Whether replacing old trolleys, retrofitting sensors, installing safety technology, converting to overhead material transport or increasing the S.W.L. – in all countries, our engineering and crane technology repeatedly prove great flexibility, reliability and cost efficiency.

Due to the cantilevered and raised special design of the new crane runway, it protrudes 3 metres into the existing wide hall area. This area can now be served by both cranes, which are equipped with SH wire rope hoists.
During charging, the portal crane drives through the hall of the raw material mixing plant to the storage bunkers at speeds of up to 63 m/min. Thanks to the compact dimensions of the trolley and wire rope hoist, the new crane system could be integrated into the existing hall and still provide the required lifting height.
A series of ST chain hoists are used in England for maintenance and replacement of railway tracks. All hoists are equipped with special load handling equipment. To ensure that the chain hoists work synchronously, they are controlled centrally.
The existing crane runway and low ceiling of the hall left little space for the new crane. The compact SH wire rope hoists, each with an S.W.L. of 8 tons in tandem operation, run on a special trolley between the box girders.
The basis for the special stacking crane is a custom solution with an SH 60 wire rope hoist that was equipped for this application with a double-grooved rope drum. The concrete elements weighing up to 5.7 t are lifted from the production line on to transport vehicles using a telescopic lifting mast. The modernisation has increased the handling of pre-cast elements by up to 20 %.
The two double-girder suspension cranes are used in a carpentry shop to transport wooden beams and prefabricated walls. Only a few centimetres remain between the suspension crane and the roof trusses. For this reason, the ST 20 chain hoist was raised to gain lifting height.
The two-part crane is equipped with 5 photo-electric barriers for non-contact signal transmission between the crane bridges. When the crane operator gives the command to lock, the control system brakes automatically on approach and locks the crane bridges.
