A braking device (8) regulates the electric motor (7) used for rotating the drum to wind-up the hose or cable, by generating a stop force (P2) opposing a force (P1) acting upon the motor in the unwind direction (AR) due to the weight of the unwound hose or cable, ensuring that the hose or cable remain fixed in the at least partially unwound position. TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Features: The braking device comprises a sensor (9) for detecting the position of a magnet (10) on the motor axle (11), linked to a motor control unit. |
