Company Vahle has developed a wide range of models drums with a spring drive designed for automatic winding of flexible power cables and control cables. They are actively used to organize the electrification of mobile equipment, in particular for various types of cranes: gantry, gantry, shipboard, dock, hoists, grabs, trolleys and other lifting and transport devices.
The coil is driven by the efforts of spiral springs made of high-quality spring steel, they are designed for an average of 120,000 operating cycles. Standard contact rings are powered by 500 V AC and 600 V DC, the control unit is 230 V.
The housing in the basic design is protected from dust and water jets, higher requirements for the shell can be implemented on request. To protect against corrosion, steel drums are galvanized (sizes 155 - 530 VLF series) or a primer and a finishing layer of epoxy resin varnish are applied to the surface.
In addition to general purpose cable drums, specialized versions are always available for special conditions and requirements: hot climates, marine applications, aggressive environments, explosive zones. As well as varieties for winding flat cables, hoses (supply of water, air, gases), steel ropes and other types.
