<p>The present invention provides a hoist fastening device (3) by means of which a hoist (4) is fastened to an all-terrain vehicle, such as a ski-slope preparation vehicle. The hoist fastening device consists of a hoisting framework (3h) which includes means for vehicle fastening. The hoisting framework is fastened e.g. to the hoisting devices of ski-slope preparation vehicles with a three-point fastening which includes a usually upper crosswise fastening pin and lower fastening cones the parties of which are locked together with a tensioning means. The hoisting framework is fastened with a substantially shelf-like body which again includes means for fastening a hoisting boom. In connection with the hoisting framework, there are adjustable support feet (5, 3b) by means of which the hoist is supported on the base in connection with hoisting. The support feet are provided with safety devices which ensure the position of the support feet and tight support during hoisting.</p> |
