The assembly comprises at least one turret and an operating boom, which is articulated to the turret with a first end thereof.

The boom lift comprises elements for supplying electrical power, at least for the movement of the machine, the rotation of the assembly and the actuation of the boom. Such elements comprise at least one first battery which is integrally supported by the machine and is arranged substantially below the element, and at least one second battery which is supported by the assembly and can rotate with respect to the machine integrally with this assembly. Such second battery is arranged substantially above the element.

A material handling vehicle is provided, which includes a frame having an aperture directed through the frame and configured to receive a battery pack, and a counterweight assembly. The counterweight assembly includes a counterweight having a first opening, and an opposite second opening, a first positioning rod having a first end, and an opposite second end. The first end is directed through the first opening. A first nut is threadingly engaged with the second end of the first positioning rod. The first nut is rotated in a first direction to advance the first end of the first positioning rod farther through the first opening to contact the frame, thereby adjusting the position of the counterweight relative to the frame.

An industrial truck includes a drive part with a drive frame and a load part. The load part includes a lift frame having a load frame, which includes a plate, a load-carrying means connected to the plate, and at least one bearing head configured to receive a lift cylinder. The at least one bearing head is connected to the plate.

An industrial truck comprises a drive part comprising a battery compartment and a battery having a cladded exterior surface and is positioned within a housing. The housing is configured to be positioned within the battery compartment. An electrical plug connector is configured to be electrically connected to the battery such that the electrical plug connector is configured to supply power to the battery during a charging process. The electrical plug connector has a plug-in direction for an external electrical plug connector and the plug-in direction has an angle of 20° to 70° relative to a horizontal axis.

A vehicle for carrying a camera crane has wheels or treads on a chassis. A battery pack assembly on the chassis, includes an AC to DC converter and plurality of batteries wired to a battery charger within a housing. The batteries collectively may have an output voltage of 30 to 36 VDC when fully charged. At least one input connector on the housing is wired to the AC to DC converter for charging the batteries. The battery pack assembly replaces and is used instead of a camera-equipment-generator.

Some aspects of the present disclosure provide a modular vehicle frame for a material handling vehicle. In some configurations, the modular vehicle frame includes a battery compartment, a handle configured to control a speed and direction of a traction wheel, and a mounting assembly configured to selectively quick-connect to a material handling attachment. In some configurations, the mounting assembly includes a mounting plate having a first side and a second side, at least one pivot block extending from the first side of the mounting plate and configured to provide a pivotal interface with the material handling attachment, and at least one locking latch attached to the second side of the mounting plate and configured to provide a selective locking interface with the material handling attachment.

A battery power supply (1) for an industrial truck (8) used in a potentially explosive area is provided, having a housing (2) having a housing body (47) and a lid (4), wherein the housing body (47) has a receiving chamber (48) for receiving a battery tray (3) that has an inner chamber (20) having a traction battery (25) arranged therein, and the lid (4) is releasably placed on the housing body (47) using securing means (53), and the battery tray (3) has a battery tray lid (49) and a base (26) having walls (17, 18) extending away from the base (26), wherein, in a region adjacent to the base (26), at least one wall (17, 18) has a recess (19) penetrating the wall (17, 18) into the inner chamber (20).

A vehicle for carrying a camera crane has wheels or treads on a chassis. A battery pack assembly on the chassis, includes an AC to DC converter and plurality of batteries wired to a battery charger within a housing. The batteries collectively may have an output voltage of 30 to 36 VDC when fully charged. At least one input connector on the housing is wired to the AC to DC converter for charging the batteries. The battery pack assembly replaces and is used instead of a camera-equipment-generator.

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.
