Abstract

The invention relates to a quick coupling for connecting implements to an excavator boom, in which one coupling body part each is arranged on the excavator boom and the implement, it being possible for both coupling parts to be secured to one another by a hook connection and a rigid locking means, at least one hydraulic, preferably single-acting, pressure cylinder (14) provided with spring retraction being provided in the area of the hook connection (3) at the coupling body part (2) arranged on the excavator boom, the piston (15) of which pressure cylinder (14), when pressure is applied, can be extended from the cylinder (14) in the direction of the implement (1) and can be pressed against a bearing surface (16) on the implement (1) and can be secured in the bearing position. <IMAGE>
