Abstract

A take-up and pay-out device for tow cables of tow lifts having a return spring for the tow cable wound onto a tow cable drum and a centrifugal brake that has at least one centrifugal weight for the tow cable drum. In that area closest to the axis the centrifugal weight has a braking surface that extends in the manner of a cam, this engaging the inside wall of the housing when the tow cable is paid out, whereas a rotatable brake shoe is arranged in that area of the centrifugal weight furthest from the axis, this moving into the operating position, i.e., in contact with the inside wall of the housing, automatically when the tow cable is taken up and simultaneously the cam-like and projecting braking surface, simultaneously lifting the inside wall of the housing. Thus, when the tow cable is paid out there is a powerful braking effect, and when the tow cable is taken up there is a somewhat less braking effect on the part of the centrifugal brake.
