    • A working equipment assembly (2) arranged to be mounted to a vehicle (4), the working equipment (6) comprises a hooklift comprising a movable arm (8) for loading and unloading a load carrying object (10). The movable arm (8) has a first end pivotably mounted to said vehicle at an arm attachment position (12) and a second end provided with an attachment member (14), e.g. a hook, arranged to connect the movable arm (8) to the load carrying object (10) during the loading or unloading wherein said working equipment (6) is operated in an attachment member mode, or to a lift-frame (16). The lift-frame comprising an attachment part (18) arranged to be attached to said attachment member (14), wherein said working equipment (6) is operated in a lift-frame mode, when said attachment member (14) is attached to said lift-frame (16). The working equipment assembly (2) further comprises a lift-frame connection arrangement (20) comprising connection lines (22), e.g. hydraulic lines, pneumatic lines, or electrical lines, adapted to connect control and operating systems of the working equipment (6) to the lift-frame (16), and an elongated rigid structure (24) configured to guide, protect and at least partly enclose said connection lines (22) over a predetermined length. The rigid structure (24) is pivotably attached to the vehicle (4) by a connection joint (26) at a connection attachment position (28), and said connection attachment position (28) is close to, and within a predetermined distance from, said arm attachment position (12), so that the elongated rigid structure (24) is arranged to follow the movement of the movable arm (8), when the working equipment (6) is operated in the lift-frame mode, and structured to stow at least a part of the connection lines (22) along the longitudinal axis A of the vehicle (4) when the working equipment (6) is operated in the attachment member mode..

    • A working equipment arranged to be mounted to a vehicle, the working equipment comprising a movable arm for loading and unloading a load carrying object, such as a container, to/from said vehicle. A lift frame assembly is provided (14) comprising a lift frame (16) with an attachment part (18) arranged to be attached to the second end of the movable arm, a pair of upper connectors (20) mounted at opposite sides of an upper part (22) of the lift frame (16), and a pair of lower connectors (24) mounted at opposite sides of a lower part (26) of the lift frame (16), adapted to attach said upper and lower parts (22, 26) of the lift frame (16) to a corresponding upper part (28) and lower part (30), respectively, of the load carrying object. The lift frame assembly (14) further comprises a set of pivotable guiding structures (54) arranged at opposite sides of the lift frame (16). A control unit is configured, during a lift frame alignment procedure, to generate an alignment control signal to move the guiding structures (54) from retracted positions into closed positions where the guiding structures (54) are in contact with side surfaces of the load carrying object (8), wherein, during movement of the guiding structures (54) from the retracted positions into the closed positions, the lift frame (16) are forced to be pivoted in order to be aligned to the side surfaces of the load carrying object (8).
