Throughout recorded history, cargo ports have played a vital role in the development of economies and countries. The importing and exporting of many types of goods are handled by countless port facilities around the globe, from small river ports to specialized sea ports that handle bulk materials, break bulk, special cargo, Ro-Ro (roll-on/roll-off) or containers. Depending on the type of goods handled by a given port, dedicated material handling machines such as cranes, loaders, and unloaders efficiently manage logistics within the port’s operations. Often operating 24 / 7 / 365, this equipment needs to be extremely reliable and able to operate in very harsh environments. Increasing global trade has driven ever increasing demands for faster, more reliable, and better performing port equipment components. Energy and data transmission systems play a crucial role in providing safe, reliable, and efficient port operations. Due to increasing requirements for “green” ports and environmental friendly handling facilities, operators will continue to convert combustion engines to electric drives. In addition, more and more ports are providing shore power for docked vessels to further reduce emissions.
With decades of experience in this industry, Conductix-Wampfler offers customized solutions for port cranes and material handling equipment and machinery. Conductix-Wampfler offers a large network of sales and engineering facilities close to our customers. Turnkey solutions and a strong after sales and servicing team support our customers in their global activities.
Motor-Driven Reels – the reliable and practical solution to manage cables for the long travel of cranes and ship loaders/un-loaders. We supply customized cable reels with magnetic clutches or frequency controlled drive units. Motorized reels are used to convert traditionally diesel-driven mobile harbor cranes (MHC) to electric power or as one more specialized solution to provide “ E-Shore” power to connect ships to an onshore power source, which allow them to shut down their engines.
Cable Festoon Systems – motorized and non-motorized festoon systems manage cables for crane cross travel, traditional but extremely reliable and durable.
Conductor Rails – efficiently provide power for crane cross travel - with the addition of dedicated rails for multiplexed data transfer. Conductor bars also can be mounted beneath the wharf to carry medium distribution voltages from 5 kV to 13.8 kV for long crane travel.
Energy Guiding Chains – manage multiple power and control cables for crane cross travel on cranes.
Slip Rings and Fiber Optic Transmitters – provide uninterrupted energy and data transmission for all rotating machines, including harbor cranes and cable reels.
Cable Protection Systems – the trench cover systems Trenchguard or the new CoverZIP system guaranty a safe cable handling and cable protection.
Spring-Driven Cable Reels – are used for portable power in maintenance areas.
