Figure 2 Device layout, cylindrical version
1 Drive unit with bevel gear, permanent magnetic coupling, and motor
2 Reel body with reeling cable
3 Cable enclosure with slip ring assembly (optional with accessories)
4 Covering hood
3.3 Function
The reeling cable winds onto the reel body using a motor. The reeling cable is kept under constant tensile
stress during operation. When the reeling cable unwinds from the reel body, it unwinds from the device
against the tensile stress. The motor brake prevents the reeling cable from unintentional unwinding when
the higher-level system is at a standstill or when the drive is in a voltage-free state.
3.4 Device usage types
The device supplies a mobile unit with electricity, and is either fixed or installed on a mobile unit.
INFORMATION
The arrows in the following illustrations show the directions for winding and unwinding
the reeling cable.
