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 catenary power.
Closed overhead lines consist of insulated conductors housed within a covered profile. These are more resistant to dust, dirt, and external influences, making them 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, ensuring 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.
Motorised 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 selected for straightforward and dependable power transmission over short distances where a motor drive is not required for retraction. The cable is wound onto the drum via a counterweight and pulley system, which generates continuous tension. This prevents the cable from lying on the floor and avoids 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.
