Abstract: A lifting arrangement for a construction machine comprises a main arm (3) which is provided with a pivot connector (4) at a proximate end thereof and an equipment connector (5) at a distal end thereof, a main arm support means (6) for pivotably supporting said pivot connector (4) of said main arm (3), wherein said main arm support means (6) is movable in a direction which includes at least a component in the front-rear direction with respect to said frame arrangement. Further a guiding means (7) is provided which is engaged to said main arm (3) at a guided portion (10) of said main arm (3) positioned between said pivot connector (4) and said equipment connector (5).

Abstract: The present invention relates to a power transmission arrangement for a construction vehicle, comprising an engine, a hydraulic power system for powering work hydraulics of the construction vehicle, which is feedable with power from the engine, the hydraulic power system including a power limiter for limiting the power supply of the engine to the hydraulic power system to different power limit values, a drivetrain power system for powering locomotion of the construction vehicle, the drivetrain power system being feedable with power from the engine, a determining device for determining an operational state of the construction vehicle, and a controller configured to control the power limiter to limit the power supply of the engine to the hydraulic power system to different power limit values, these power limit values being set depending on the operational state of the construction vehicle determined by the determining device.

Abstract: Described is an excavator comprising an articulated boom and a balancing mechanism at least partially assisting a movement of the boom from a lower position to an upper position by applying a pulling force on said boom.

Abstract: A track wheel suspension for a construction machine is introduced. The track wheel suspension comprises a track wheel engageable to a track and a swing device comprising a first coupling portion. The first coupling portion is arranged for rotatably supporting the track wheel. Furthermore, the track wheel suspension comprises a swing bar with a first bar end which is arranged for being mounted to a second coupling portion of the swing device. The swing bar provides a swing axis which is offset from a rotation axis of the track wheel such that a swing movement of the swing device enables a movement of the track wheel in a direction which is substantially perpendicular to the rotation axis.

Abstract: A track wheel suspension for a construction machine is provided comprising a track wheel engageable to a track, a swing device, a swing bar and a restraining mechanism for at least restraining a movement of the swing device about a swing axis in at least a first direction.

Abstract: A lifting arrangement for a construction machine is provided which includes a main arm (3) which is provided with a pivot connector (4). The pivot connector (4) is pivotably supported on a main arm support means (6). The main arm support means (6) is moveable in a direction which includes at least a component in the front-rear direction with respect to a frame arrangement of a construction machine to which the lifting arrangement can be applied. Based on a control of a main arm actuating element (11) and an auxiliary actuating element (21), a path of an equipment connector (5) upon moving said main arm (3) between a lowered position and a lifted position can be achieved which follows a predetermined path.
