A winch ( 1 ), a vehicle including the same and a method of operating associated thereto. The winch ( 1 ) is used with a strap ( 15 ) for fastening a load onto a transportation vehicle, and comprises a tightening assembly ( 3 ) and a gear assembly ( 5 ). The tightening assembly ( 3 ) comprises a support structure having first and second support flanges ( 7, 9 ) and a cross member ( 11 ) extending between the flanges ( 7, 9 ). The cross member ( 11 ) is devised for mounting onto a corresponding side track of the vehicle. The tightening assembly ( 3 ) also comprises a tightening reel ( 13 ) for receiving a portion of the strap ( 15 ) to be tightened about said reel ( 13 ), the tightening reel ( 13 ) being pivotally mounted onto the first and second support flanges ( 7,9 ). The gear assembly ( 5 ) is operatively connected to the tightening assembly ( 3 ), and comprises a gear ( 17 ), a worm ( 19 ), and a casing ( 21 ). The gear ( 17 ) is securely mounted about the tightening reel ( 13 ) so as to rotate with said reel ( 13 ). The worm ( 19 ) is positioned adjacent to the gear the worm ( 17 ) is threadedly engaged with the gear ( 19 ) so that a rotation of the worm ( 17 ) drives the tightening reel ( 13 ) via the gear ( 17 ), along opposite directions of rotation, for either fastening or unfastening the strap ( 15 ) onto the tightening reel ( 13 ). Excess portion of the strap 15 may be wound about a winding assembly ( 27 ) which is removably mountable onto the tightening assembly ( 3 ). |
