(54)	Apparatus for detachably securing a loader attachment on a vehicle

(57) A device is described for detachably securing a front-loader attachment to a carrier vehicle, using a respective crank pin on each side of the vehicle, which is pivoted across an angular range terminating at the top dead centre of the crank, so that the crank pin is forcibly engaged, in order to lock a coupling member at the front-loader end received in a bracket at the vehicle-end in a locking position by means of initial tension and which in turn can be locked in the locking position, respective adjusting members being provided to set the requisite initial tension when the crank pin is in the locking position.
The device is distinctive as a means of keeping the number of re-settings to a minimum, since the adjusting member (10) is adjusted so that the requisite initial tension is built up approximately across an angle (Ω) after the start of the forced engagement-angular range (α) and across the entire forced engagement-angular range (α) by means of a locking device to secure the crank pin.
