Abstract (en)
[origin: WO2006083172A1] A quick coupling device (1) for connection to a work tool (2) which has quick coupling fastenings in the form of two parallel shafts (3, 4) that extend between supporting frames (5, 6) on the work tool, wherein the device has at a first end (I1) a first set of hooks or cups (7, 8) with their opening facing downwards and adapted to abut with a part of the circumference of a first (3) of the shafts, and has at its second, opposite end (1") a second set of hooks or cups (9, 10) with their opening facing towards the second end and adapted for abutment with a part of the circumference of a second (4) of the o shafts, and a first wedge (11) that is insertable under the first shaft (3) for locking the work tool (2) to the quick coupling device (1). The quick coupling device also has a second wedge (12) that is intended for insertion under the second shaft (4). The first (11) and the second (12) of the wedges are adapted to press the hooks or the cups (7, 8; 9, 10) against the respective one (3; 4) of the shafts with a clamping force essentially 5 along the same axis as the load forces on the hooks or the cups (7, 8; 9, 10) that are caused by the work tool when in use. The two wedges (11, 12) are slidable along respective sliding guides (H', 12') and are movable back and forth by means of one common actuator (13). The device is well suited for work tools which are reversible with regard to use.
