A hooklift arrangement (2) for loading and/or unloading a load carrying object (300) onto and off a vehicle (200), the hooklift arrangement (2) being structured to be mounted to the vehicle (200), the hooklift arrangement (2) comprising a lift arm (100) comprising a main section (109) arranged to pivot around an axis parallel to the plane of the chassis (103) of the vehicle, and a movable section (112) arranged to be attached to, and move relative to the main section (109) of the lift arm (100), the movable section (112) further comprising an attachment tool arranged to engage the load carrying object (300) during loading and unloading. The hooklift arrangement further comprises an actuator system (4) comprising at least a first actuator (104) controlling the pivot angle of the lift arm (100) and a second actuator controlling the movement of the movable section (112) relative to the main section (109) of the lift arm (100), and a sensor system (6) comprising sensor units configured to determine a pivot angle of the main section (109) relative to the chassis (103) of the vehicle, and a position of the moveable section (112) relative to the main section (109), and to generate sensor signals in dependence thereto, and a processing unit configured control the operation of the at least first and second actuators for loading and/or unloading the load carrying object (300) onto and off the vehicle (200). The processing unit is further configured to receive an automatic mode signal for entering an automatic mode, and in response of receipt of the automatic mode signal, the processing unit is configured to determine control signals to perform a synchronous movement of the lift arm (100) and movable section (112), such that the attachment tool is moved in a horizontal direction away from, or towards, the vehicle (300) in a predetermined height of the attachment tool relative to the vehicle.
