General Information Spring driven cable reels are subject to the standards and norms as specified in the latest edition of VDE 0100 and the UVV. The springs are made of special high-grade steel which guarantees a long lifetime. Every spring is mounted inside a spring housing in order to avoid friction and wear. The slipring assembly is mounted in a solid glassfiber reinforced plastic housing that can withstand corrosion and mechanical wear. The housing is designed to minimise condensation and to guarantee complete water tightness through glands and seals. Corrosion protection is also an...

Operating voltages Please find the operating voltages in the respective slipring data tables. Maximum current values All drums and slipring bodies are designed for the maximum allowed current values of the cable at 100% ED. (duty cycle). Please find the maximum allowed values in the respective slipring data tables. Earth conductor and number of poles All drums and slipring bodies for voltages > 24V are manufactured with an uninsulated protective earth conductor (PE). Number of poles = number of insulated poles including PE. In your order form, please state the number of poles, protective...

CLT MODULAR SYSTEM The concept of the Cavotec Alfo CLT reels is to provide a modular system that retains all the quality and reliability of a standard spring driven cable reel. To guarantee the above, all assembly will take place at Cavotec Alfo by our specially trained and experienced staff. Only when requested will we ship the separete components of the CLT reels unassembled. In this case the modular design allows for easy storage and thanks to the innovative design of the reels, replacing just one part is extremely easy. The photographs on right show the different packages that can be...
