Lifting and moving of goods is part of almost every production, assembly, or logistic process. Depending on the size and weight of goods and materials, machines for lifting can be designed very differently. However, they all have vertical and horizontal movements in common. Next to floor mounted transportation and lifting equipment, cranes are the most used material handling equipment for this task. From simple hoists on fixed or swiveling beams, to overhead cranes, to fully automated and dedicated process cranes, the range of crane types is as wide as the kinds of goods that are handled by them – all over the world, every day. Energy and data transmission systems play a crucial role in the safe, reliable, and efficient operation of all types of cranes. Due to the different designs and functionalities of cranes, power supply and data transmission systems need to be very dedicated to fit the exact requirements. Also, the wide range of different environments where cranes operate, such as factories, steel mills, aluminum smelters, scrape cranes, timber mills, and waste-to-energy (WCR) puts very high and specialized demands on energy and data transmission systems.
Conductix-Wampfler is the worldwide leader in electrifying cranes. We offer standardized solutions for all types of cranes and can handle customized needs as well. Conductix-Wampfler offers a large network of Sales and Engineering facilities close to our customers. Local stocks and short lead times on standardized items guarantee the highest possible level of support for our customers.
– for the runway travel of factory cranes, single pole insulated, multi pole or enclosed conductor rail systems have proven to be the most reliable and cost-effective solution. Cross travel on cranes can be handled with conductor bars as well, using dedicated data transfer systems
Energy Guiding Chain – can also manage cables for the cross travel on cranes as well as for cranes with extendable booms.
Spring-Driven or Motor-Driven Cable Reels – can manage cables used in vertical lift applications.
Slip Rings – pass power and control to the moving part of cranes that rotate 360 degrees.
Rubber or Cellular Bumpers – cushion the direct part-to-part impacts of crane elements.
Jay Radio Remote Controls – offer a safe way of operating or monitoring machines from a distance. The comprehensive range of industrial and safety radio remote controls offers countless solutions to adapt to an extensive number of crane applications.

Cellular bumpers / buffers are characterized by high energy absorption with long compression lengths. This results in low final pressures and favorable retardation values. Cellular buffers are made from a cellular Polyurethane Elastomer with high structural resistance. Their principal quality is the volume compressibility, which is responsible for their relatively low transverse expansion during load application. Cellular buffers are resistant to aliphatic hydrocarbons, such as oil and grease, and against ageing. A general resistance can therefore be assumedfor technical applications.
The cellular buffers are not resistant to strong acids and leaches. The operating temperature is between –20°C and +80°C.
Generally special types are only offered and supplied on request. If cellular buffers are mounted over 3 m high they have to be secured by installation of safety ropes.
Material of the cellular body
Due to their excellent properties of energy absorption the cellular buffer Programme is a suitable complement to the rubber buffer Programme. Their volume compressibility allows long compression lengths, which allows very good retardation values.
