Grease unit

A grease unit especially for tail lifts, consisting of a cylindrical grease container (1) provided with a grease press, such as a spring-loaded (2) press piston (3) pressing grease into a dosage cylinder (4) which forms part of the grease unit and by means of which the grease can be pressed out onto the objects (6) to be greased. The dosage cylinder (4) is coupled to the drive power of the tail lift, i.e. the hydraulic system (5), with the result that the device works always when the tail lift is used and greases any necessary areas (6) of the tail lift.
