Demag has partnered with Vowisol, which produces transparent conservatories, orangeries, greenhouses and pavilions, on its new production facility.
The company based in Radeberg, Germany, is continuously growing and needed single handling systems so that employees can lift, move and transport components to be machined through the various steps in production.
It also needed to take into account reduced headroom in some parts of the workshop and to transport the components over machinery.
Demag planning engineers designed a KBK system with a 24.5-metre-long crane runway, along which a double-girder crane with a span of 5347 mm travels. The DC-Com electric chain hoist used for this solution has a load capacity of 1,250kg and provides the customer with a service life of 3,200 hours of operation under full load.
The chain hoist is controlled via a DSC pendant controller. The X and Y axes of the transport and handling system need no drives. The smooth-running suspension crane enables loads to be transported horizontally when the operator moves them in the required direction.
“We had already gained very good experience with a Demag slewing jib crane in our production area, which worked very well in practice. For our current extension, we wanted to have the relevant components transported throughout the entire workshop area by just one employee to meet flexible needs. That can now be done without any problems with the KBK suspension crane system,” said Arian Vorwerk, MD, Vowisol.
“It is in use every day and fully justifies our investment in a crane system. Particularly heavy components can be safely moved overhead through the workshop by one person quickly, easily and without taking up any space.”
The DC-Com chain hoist is perfect for daily operations in the production area of the conservatories. The gearbox and slipping clutch are maintenance-free for up to 10 years and the brake of the selected DC-Com 10-1250 is maintenance-free for up to five years.
At the same time, the solution needed to be flexible enough to allow all the manufacturing equipment to be served in this part of production and Vowisol wanted an ergonomic solution in line with health and safety requirements.
A special feature is the raised crane bridge of the KBK double-girder crane. It enables maximum utilisation of the available headroom in the workshop. Measured from the floor, the suspensions are located at a height of 3942mm.
The chain hoist is installed on a bracket between the two crane girders and is located well above the crane girders. In this way, the chain hoist can achieve a fully acceptable lifting path of three metres to allow the loads to be transported from one workplace to the next.
