They have been designed for the overhead moving of loads within a building, such as in production and assembly areas: gantry cranes. As they are fixed to the building, they allow for three directions of movement, which cables, hoses and energy supplies also have to follow. Short downtimes, low maintenance requirements and the functional reliability of the system are important from an economic point of view, but also with regard to occupational safety. Due to the individual building conditions and areas of application, gantry cranes are usually custom-made, from the crane track to the energy supply system. Our energy supply systems have been developed for different operating conditions, but also for the various standards of the international markets. They are designed in an optimal way, as a complete system or individual component, and with a predictable service life.
