Efficient crane technology for machinery construction and plant engineering

DIEM Werke GMBH is one of the leading manufacturers in Europe in the areas of construction machines, tank construction and plant engineering. The company based in Hörbranz (Vorarlberg) and certified in accordance with EN ISO 9001 has been developing construction machines and devices, including mixers, crane forks and crane skips, for the past few decades. They have also been developing the right concept for every single requirement in tank construction and plant engineering. 8 overhead cranes with single girder as well as 10 workstation jib cranes, all from Dahs Krananlagen GmbH in Buchholz, are put to use in the newly built production hall spanning 7,000 m2. All of them are fitted with electric hoists from SWF Krantechnik GmbH in Mannheim.

Overhead cranes with loads from 3.2 t to 10 t were installed in the production halls and in the loading area. The cranes have a span width of 22 m. The NOVA electric wire rope hoists have been designed in the short version to optimally utilise the room height with the short hook dimension. The trolley power supply on the crane bridge was provided through cable carriers. All cranes are remote-controlled, which gives the crane operator greater freedom of movement and allows him to work safely when moving the attached loads.

As the materials are moved overhead, the entire hall space is put to best use. The optimum approach dimensions of the NOVA electric wire rope hoists also play an important role. Wall-mounted jib cranes are used in addition to the overhead cranes. These workstation cranes are fitted with the CHAINster electric chain hoists, which can each carry a load of 1,000 kg. The electric chain hoists are moved by a motor trolley on the beam. A wall-mounted jib crane is motorised due to the long beam for the slewing motion. The other compact jib cranes can be moved manually to the desired position.

A monorail track with two NOVA electric wire rope hoists, each carrying 10 t loads, was installed in the varnishing cabin. The hoists are fitted with an electronic anti-collision device. This enables workpieces weighing up to 20 t to be positioned safely and gently in frequency-controlled tandem operation.
