Abstract
The utility model relates to the technical field of engineering machinery and discloses a winch and the engineering machinery. The winch comprises a machine frame, a roller, a roller revolving shaft and an inhaul cable wound on the roller and further comprises a spiral member fixed on the machine frame, wherein the roller and the roller revolving shaft are axially and slidably connected. The winch provided by an embodiment enables the roller and the roller revolving shaft to be connected axially and slidably, and the roller performs spiral drive through a screw and a nut. When the roller rotates, displacement of a rolling-out point of the inhaul cable and displacement of the roller relative to the roller revolving shaft are identical in size and opposite in direction, therefore the rolling-out point position of the inhaul cable remains unchanged, drawing force of the inhaul cable to a material trolley remains consistent with the direction of guide rails, and uneven abrasion of the two-side guide rails and the material trolley is avoided. Due to the fact that the drawing force remains consistent with the direction of the guide rails, energy consumption of the winch is reduced helpfully.
