  • Winding device, particularly for winding up fire hoses
    Patent number: 6332586
    Abstract: A winding device for fire hoses (40, 42), loading straps, etc., comprises a freely rotatably mounted, sleeve-shaped coil (12) having a longitudinal cavity (36) which, circumferentially, is defined between two clamp faces (14a, 14b). Within the cavity (36) is disposed a clamp means (34) firmly connected to a crank device (26′, 26, 24, 32) and pivotal from a first position, resting against a first clamp face (14a), to a second position, resting against a second clamp face (14b). The clamp means (34) is a straight, rod-shaped element connected to the crank shaft (24) through a lateral crank arm (32) outside the inner cavity (12′) of the coil (12). A starting portion of a fire hose, e.g. a loop-shaped portion (42) at the center of a double-laid fire hose (40), can be placed around such a clamp means (34), whereupon the hose is wound up.
