A loader vehicle includes a front unit and a rear unit pivotally connected to each other by an articulated joint arrangement allowing mutual rotation of the front unit and the rear unit. The loader vehicle includes a loading unit assembly and a control valve arrangement arranged to hydraulically control the loading unit assembly, wherein the control valve arrangement is arranged at a rear portion of the front unit in the vicinity of the articulated joint arrangement.

Loader vehicle

A wheel loader front unit includes a frame for a wheel loader, the frame including an upper joint element and a lower joint element for connecting the frame to a rear unit of the wheel loader, and for transferring loads between the frame and the rear unit, the frame including a lift arm mounting point for a pivot connection of the frame and a lift arm for lifting an implement of the wheel loader. The upper and lower joint elements are arranged so that a first of the upper and lower joint elements, during use of the wheel loader, transfers a larger vertical load than a second of the upper and lower joint elements, and the lift arm mounting point is located closer to the first of the upper and lower joint elements than to the second of the upper and lower joint elements.

Wheel loader front unit and a wheel loader

The invention provides a wheel loader front unit including a frame, the wheel loader front unit further including two hub supporting elements, each hub supporting element being arranged on opposite sides outside of the frame for supporting a respective hub unit, a lift arm for supporting an implement of the wheel loader, the lift arm being arranged to be pivoted around a pivot connection to the frame by a main hydraulic cylinder, and a tilting hydraulic cylinder arranged to actuate a tilting movement of the implement in relation to the lift arm, wherein the wheel loader front unit further includes a slave hydraulic cylinder hydraulically connected to the tilting hydraulic cylinder for controlling the tilting movement of the implement when the lift arm is pivoted by the main hydraulic cylinder, wherein the slave hydraulic cylinder extends between the lift arm and one of the hub supporting elements.
