  • Patent number: 6161788
    Abstract: A reeling device for hoses and/or cables, wherein the reeling device (1) includes a rotatable member (3) which is rotated during unwinding or reeling of the hose and/or cable (4) and wherein a spring device (5) is provided to cooperate with the rotatable member (3) such that the spring device (5) a) is stretched when the rotatable member (3) is rotated in an unwinding direction (AR) when the hose and/or cable (4) is pulled out from the reeling device (1), and b) after pulling out the hose and/or cable (4) from the reeling device (1) rotates the rotatable member (3) in a reeling direction (UR) for reeling the hose and/or cable (4) on the reeling device (1). An electric machine (8) is provided to be driven or operated by the rotatable member (3) when the spring device (5) rotates said rotatable member (3) in the reeling direction (UR) such that the electric machine (8) generates electric energy.

  • Patent number: 6158684
    Abstract: A reeling device for hoses or cables, whereby the reeling device (1) comprises a non-rotatable member (5), a member (3) which is rotatably mounted thereon and which rotates during unrolling or reeling of the hose or cable (2), a spring device (22) for rotating the rotatable member (3) in a reeling direction for reeling or winding up the hose or cable (2) and a viscosity brake (25) for slowing down the rotary speed of the rotatable member (3) when said rotatable member is rotated in the reeling direction by the spring device. The viscosity brake (25) includes a stationary brake housing (26) which is mounted on members (38) of or connected to the non-rotatable member (5) and the viscosity brake (25) has a movable member (27) which is located inside the brake housing (26) and which includes a movement-transfer device (32) which is provided outside the brake housing (26) for obtaining movement-transfer cooperation between the rotatable member (3) and the movable member (27) of the viscosity brake (25).
