The overhead line ensures the safe transmission of electrical power and control signals. Shunt overhead lines are used where it is necessary to carry multi-core cables routed along a support profile with shunt trolleys - typically for cat power.
Closed overhead lines consist of insulated rails with rails in a covered profile, which are more resistant to dust, dirt and external influences and are suitable for more demanding industrial environments for power supply.
The specific type is selected according to the length of travel, the type of operation and the environment so that the crane power supply is reliable, safe and reasonably maintenance-free.
Motor cable drums are used where reliable power or signal transmission is required for longer runs and higher frequency of duty cycles. The cable is wound and unwound by the drum drive, so there is no dragging on the floor or excessive twisting.
We adapt the solution to the type of equipment, travel length, speed and steering method. The emphasis is on correct cable routing, protection against mechanical damage and safe operation in the environment.
Motorized drums are available in various configurations depending on the required power supply, cable type and operating conditions, including the connection to the crane or manipulator control.
Gravity cable reels are chosen where simple and reliable power transmission is needed for short runs without the need for a motor drive to wind up. The cable is wound onto the drum using a weight and pulley system that creates a constant tensile tension, so the cable does not lie on the floor and is not subject to unnecessary mechanical damage.
The solution is suitable for cranes, mobile hoists and other equipment with a limited range of movement. The design takes into account travel length, cable cross-section and weight as well as operating conditions to ensure a safe, functional and low-maintenance winding system.
