An engine exhaust system is accommodated in a counterweight portion without reducing either the efficiency of cooling by a radiator or the efficiency of purifying exhaust gas by an exhaust gas purification device. A body has a work device provided at the front and the counterweight portion at the rear. A ventilation path provided in the counterweight portion includes an elevated part formed between a bottom of a front portion and a bottom of a rear portion. The purification device and a muffler are disposed in the rear portion of the ventilation path so as to be positioned one above the other with the purification device lying above the muffler and having an upper portion protruding above the bottom of the front portion of the ventilation path. A windbreak plate made from a heat insulating material is disposed forward from the purification device so as to face the latter.

The invention relates to a cargo handling vehicle for handling cargo within narrow aisles. The cargo handling vehicle comprises means for autonomous navigation, a chassis having at least two pairs of ground engaging means, a lifting boom. The lifting boom having a first end and a second end wherein the first end is arranged to the chassis and the second end is provided with a lifting unit. The first end of the lifting boom is attached to the chassis enabling movement of the second end in a vertical and horizontal direction, and the lifting unit is arranged rotatably in a horizontal plane. Each of the ground engaging means are independently steerable and individually driven by a respective driving means. Further, the invention also relates to a method in a cargo handling vehicle.

The disclosure relates to an anti-collision structure for an engineering machine, the engineering machine has a tail frame arranged at a rear end. The anti-collision structure comprises an anti-collision body that at least partially covers side walls and a rear end wall of the tail frame, wherein the anti-collision body is made of plates and configured to have a streamline shape and a hollow structure. The anti-collision structure of the disclosure can effectively avoid collision to the rear end or tail of the engineering machine when the machine climbs or reverses, which improves the overall strength and impact-resistance of the tail frame and the main frame of the engineering machine. In addition, the three-dimensional streamlined shape of the anti-collision structure matches the whole vehicle in style, adding highlights for the electric driver. The disclosure also relates to an engineering machine comprising the anti-collision structure.

A working machine including a machine body having an operator cab, a ground engaging propulsion structure to permit movement of the machine over the ground, a load handling apparatus coupled to the machine body and moveable by a movement actuator with respect to the machine body, and an electric energy storage unit for providing power to the working machine. The working machine includes a longitudinal axis, wherein the operator cab is positioned towards a first side of the working machine with respect to the longitudinal axis, and the electric energy storage unit is positioned towards a second side of the working machine with respect to the longitudinal axis, wherein the first and second sides are located opposite each other.

A device for use in lifting, transporting and installing sheet material has a base, wheels on which the base is supported, a mast that extends upwardly from the base, a carriage that is in engagement with the mast, a supporting head that is mounted to the carriage, and a lifting mechanism to provide support to the carriage in the longitudinal direction of the mast. The wheels include rear wheels that are connected to the rear of the base in a manner that permits steering of the device during movement across a surface, and a front wheel set that is connected to the front of the base. The front wheel set includes a wheel to each side of the device, and the wheels of the front wheel set are rotatable about a common axis. The connection of the mast to the base is such that the mast is rotatable relative to the base about a rotational axis. The device further has an actuator that is operable to change the angular position of the mast relative to the base. The supporting head is configured to support sheet material above the surface.
