摘要： Winch arrangement primarily intended for withdrawal of hung trees or other objects, comprising a holding unit for fixing the winch to a stationary object, and a winch unit connected to a frame. The holding unit includes an elongated fastening means which at one end is secured to the frame, while its intermediate portion is drawn around the stationary object and its other end is connected to the frame via a tightening mechanism. The winch unit comprises a drum rotatably mounted on a shaft in the frame for unwinding and winding a flat band which at its free end has a fastener for connection to the tree, a control mechanism for the operation of the drum, and an engageable and disengageable ratchet mechanism for selectively preventing unwinding of the band.
