Product Portfolio
  • Energy Transfer

  • Generally speaking, energy supply systems are used when a mobile consumer is supplied with the energy and/or intelligence required by the consumer for its movement of any kind from a fixed feed point.
    Mobile consumers are technical systems that take over transport and connection work at many locations throughout the world of technology. For example, from port handling to material flow technology.

    Energy supply systems are used for a wide variety of media, such as electricity, water, air, gas, oils of all kinds and in particular - but with increasing frequency - for data traffic between the feed point and the mobile machine.

    Machines or devices as energy supply systems for the above mentioned applications can be designed differently. They differ in terms of the length of the path, the medium to be transmitted, the frequency of the movements, the speed of the consumer or the specific location of use.

    Cables or hoses are used to transport the media within the transmission distance from the feed point to the moving consumer.
    Machines and devices as energy supply systems that meet the requirements for the above applications are, for example:

    • Conduits (cables) - Reels or hose reels
    • Cable (cable) - trolley systems or hose reel systems
    • Cable - chain systems or hose chain systems

    Before deciding which energy supply system is ultimately to be used, it is essential to consider all boundary conditions such as

    • Place of use ( with all environmental influences )
    • Distance travelled by consumers
    • Speed of the consumers
    • Frequency of operation
    • Type of media
    • Number of media required.
      • Cable rewinders

      • Various cable lengths and cross sections
        Protection classes IP42 up to IP65
      • Cable drums

    • E-Mobility

    • transprotec GmbH offers movable energy supply systems as well as load supply systems for individual supply as well as depot and fleet supply or loading areas. In both private and commercial areas, our charging drum systems adapt flexibly to all environmental and operating conditions. For example, we provide systems that supply car parks, carports as well as vehicle fleets in the commercial vehicle sector or in local public transport with charge current.
        • Flexible loading drum systems for wall, ceiling, floor and underfloor mounting

        • Our solutions can be adapted to a wide range of conditions with almost no problems. In addition to manual operations, we also offer automated plug-and-socket cable feeds.
        • Energy supply for mobile consumers without battery use

        • Stationary consumers are e.g. truck trailers which must continue to be supplied with energy during their standing time due to the load to be cooled. To minimize the risk of tripping and injury, we offer flexible charging current systems. By means of movable or rotating spring cable reels on portals or swivel arms, refrigerated trailers can be supplied with energy during loading and unloading or during logistically induced downtimes, thus maintaining their interior temperature.
          Another example concerns electric forklifts that are transported on their way to the customer without batteries for weight reasons. During loading, the forklifts are supplied with energy via our energy supply system (180° swivelling spring cable drum on the 180° swivel arm).

          Our spring cable reels for energy supply can be used flexibly in all conceivable areas - via wall, ceiling or floor/underfloor mounting they supply your vehicles with energy without hindering your work or producing supposed sources of danger.

        • Load feeding systems

        • Optimization of battery charging processes
          transprotec Gmbh develops various mobile load feeding systems for all parking, depot and fleet loading areas. We offer you safe, space-saving, efficient solutions for optimising battery charging processes for car parks, bus depots or even forwarding companies. The central component of our respective solutions are cable drums, which are flexibly mounted to the structural conditions and can be moved if required.

          This allows different vehicle types and models to be connected to the respective charging systems. Depending on the application, the cable reels can be designed with a spring motor or electric drive in 230 V or 400 V versions.

          In addition to energy transmission, we also offer the possibility of transmitting signals for system safety and system monitoring. On request, we can offer you solutions for the transmission of signals such as Ethernet 100 Mbit/s, Profinet, CAN bus, Profibus.

          This enables us to realize charging voltages of up to 1000 VDC and charging capacities of up to 200 kW with our system solutions.

        • Chain hoists in various designs

          Chain hoists belong to the hoist family alongside wire rope hoists and cable winches. They are basically used for lifting and lowering loads. Chain hoists are used as hoists in rail systems or for crane systems and in stationary operation as an aid for assembly work or for loading machines and systems.
          In addition to the normal operating conditions in indoor and outdoor operation, the chain hoist can also be manufactured in an Ex version (operated with compressed air) for use in explosion-protected environments.

          Chain hoist with or without motor?
          If the chain hoist is operated manually, it is a manual hoist. The range of manual hoists is divided into spur gear pulleys and ratchet hoists or lever hoists
          Motor driven chain hoists are used as Electric chain hoist or Air chain hoist manufactured.

            • Electric chain hoists

            • Load capacities up to 25 t
              230 V / 400 V
              Low maintenance

              For electrically operated chain hoists, the hoist motors can be supplied in 230 V or 400 V versions. The control of the electric chain hoists can be in the form of direct control or contactor control. The contactor-controlled chain hoists also have adjustable limit switches which are designed as operating limit switches. Load capacities of up to 25 t can be achieved with electric chain hoists.

            • Pneumatic chain hoists

            • Load capacities up to 100 t
              For continuous operation
              duty cycle: 100%

              For the use of air chain hoists, it must be taken into account that the devices generally cover the performance data specified in each case at a flow pressure of 6 bar. Furthermore, when selecting a unit, it should be checked whether the air consumption at full load operation can be ensured by the compressed air supply. A compressed air chain hoist can be designed with a chain control or button control. A decisive advantage of a compressed air chain hoist is that the lifting and lowering speed can be infinitely varied. Compressed air chain hoists can be supplied with load capacities of up to 100 t.
