A working machine, in particular a material handling machine, has a boom and a boom bracing actuated by an actuator operatively connected to the boom bracing by a lever rotatably articulated to a turntable, to introduce the required tensile force into the bracing.

Working machine comprising a boom and a boom bracing

The present disclosure relates to a work machine, in particular to a hydraulic excavator, having at least one ballast device, wherein the ballast device comprises at least one ballast weight and at least one ballast support. The present disclosure is furthermore directed to a ballast weight for a corresponding work machine.

Work machine having a ballast device

The present disclosure relates to an implement with a boom, wherein the boom is pivotally mounted about a horizontal axis via a bolt connection on a basic unit of the implement, with the bearing of the boom on the basic unit being effected via three bearing plates with corresponding bearing points for the bolt connection.

Implement with a boom

The present invention relates to a work machine, in particular to an excavator, having a boom, an extension element and a piece of working equipment, wherein the extension element is attached to a pivotal connection axle of the boom via a first gimbal mounting and bears the piece of working equipment, wherein the piece of working equipment is attached to a pivotal connection axle of the extension element via a second gimbal mounting.

Work machine, in particular excavator

The present invention relates to a piece of working equipment, in particular to an excavator or to a machine for the transfer of material, having an element movable via at least one working hydraulic cylinder, wherein at least one energy recovery hydraulic cylinder is provided for the recovery of energy from the movement of the movable element. In accordance with the invention, the energy recovery hydraulic cylinder is filled with gas at the bottom side and has a hollow piston rod.

Piece of working equipment

The present invention relates to a traveling working machine, in particular an excavator, with an undercarriage on which the traveling gear is arranged, and an uppercarriage rotatably arranged on the undercarriage about a vertical axis of rotation. In accordance with the invention, the load-bearing steel construction of the uppercarriage is composed of at least one first and one second element, which are connected with each other via bolts and/or screws.

Traveling working machine

The invention relates to an excavator or to a machine for material transfer comprising an element movable via at least one hydraulic cylinder. In accordance with the invention, one or more hydraulic cylinders are additionally hinged to the element, with the additional hydraulic cylinder(s) being connected to one or more hydraulic accumulators.

Excavator and a machine for material transfer

This invention relates to a digging or gripping tool with at least one cutting edge, wherein rollers are disposed along the outer edge of the cutting edge in accordance with the invention.

Digging or gripping tool

A multi-scoop grab, having at least one grab scoop () with at least one prong, wherein at least one wear element () is arranged at the at least one grab scoop () such that the main wear regions are covered by the at least one wear element () ().

Grabbing tool

The invention concerns a material transloading equipment unit with an undercarriage and a turntable connected with this undercarriage by means of a track ring, on which an arm that can be pivoted by means of at least one hoisting cylinder is pivot-mounted. According to the invention, on the one hand at least one additional pivot point for the arm is provided on the turntable and/or on the boom foot, and at least one additional pivot point is provided in the arm or in a pivot plate on the arm. This allows a number of possible combinations for the kinematics of the arm.
