Although most global trade travels by container, a substantial portion is handled as bulk cargo. Dry bulk cargo facilities process, store, and move a wide range of minerals, ores, agricultural goods, and forest products. Many bulk facilities run 24/7, so the material handling machinery must be heavy-duty, safe, and easy to maintain. Durable and reliable energy and data transmission systems are needed to power stacker / reclaimers, tripper conveyors, ship loaders and unloaders, radial stackers, stack racks, hoppers, and cranes, as well as processing equipment such as crushers and sizers. Electrification must be customized to the type of machine, the application, and the specific material being handled. In addition, many electrification systems must withstand dusty environments, corrosive materials, and even hazardous (explosion-proof) conditions.
Customized Conductix-Wampfler energy and data transmission products are well suited to the demands of the bulk handling industry. Our decades of experience and broad product range insure that customers will get the best possible solution. Our customers’ global activities are supported with our turnkey systems and strong after-sale service from our worldwide sales and engineering network. We offer:
Motor-Driven Cable Reels – monospiral or level wind reels to handle main power and data transmission cables or hoses for long-travel stockyard machines such as stacker/reclaimers. Motorized reels feature magnetic clutch or variable frequency drive (VDF) with special slip ring assemblies and fiber optic transmitters for uninterrupted energy and data transmission.
Festoon Systems – for dusty and harsh environments, highly reliable festoon systems provide cable management for crane bridge travel, ship loaders, and bulk conveyors. These run on I-beams or on square “diamond” track to minimize the collection of debris and to yield the best possible performance.
Energy Guiding Chains – depending on the application and the cable package, heavy duty energy guiding chains can be used in linear or circular applications to manage cables and hoses on bulk machines.
Spring-Driven Cable Reels – can be used for vertical or horizontal movements of bulk handling machines without the need of energy for the operation of the reel.

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.
