A planetary gear module for a swing reducer of a construction machine is provided. The planetary gear module can fit between first and second adjacent planetary gear modules. The planetary gear module comprises a planetary gear stage and a stage support for supporting the planetary gear stage, the stage support comprises an input support interface for stacking the first adjacent planetary gear module onto the planetary gear module and an output support interface for stacking the planetary gear module onto the second adjacent planetary gear module, the planetary gear stage comprises an input gear interface for operatively connecting the planetary gear module to the first adjacent planetary gear module and an output gear interface for operatively connecting the planetary gear module to the second adjacent planetary gear module. The input and output support interfaces as well as the input and output gear interfaces are configured to match to each other.

Planetary gear module for swing drive

An excavator with a boom comprises a main electrical drive system with an electrical power storage unit. The excavator comprises an electrical drive configured to actuate movement of the boom to raise and/or lower part of the boom. The excavator comprises a separate fluid-operated, auxiliary actuation system for storing potential energy of the part of the boom during lowering thereof and for using the stored potential energy to support raising of the part of the boom. The auxiliary actuation system is configured to store the potential energy and to support raising the part of the boom autonomously without interaction with the main electrical drive system.

A tool changer for a construction machine includes at least one tool retaining portion for holding a tool being mountable to the tool mount, the tool changer being configured to be movably attached to the construction machine. The tool changer also includes and a moving mechanism for moving the tool retaining portion in alignment with the articulated boom of the construction machine to allow for picking of the tool by the tool mount. The construction machine includes an articulated boom with a tool mount.

Tool changer for a construction machine

A tool for a construction machine includes a first interface that is located at a first location on the tool, and a second interface that is located at a second location on the tool being different from the first location, wherein each of the first interface and the second interface is individually configured to mount the tool on the construction machine, and wherein the construction machine includes a loader bucket.

Multiple interface tool for a construction machine

A track wheel suspension for a construction machine is provided including 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.

Track wheel suspension for a construction machine

A track wheel suspension for a construction machine is introduced. The track wheel suspension includes a track wheel engageable to a track and a swing device including a first coupling portion. The first coupling portion is arranged for rotatably supporting the track wheel. Furthermore, the trackwheel suspension including 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.

A construction machine that includes a machine frame and an articulated boom. The articulated boom is pivotably mounted to the machine frame. The construction machine is configured to be operated in a loader mode in which a first tool is mounted to the articulated boom, and in an excavator mode in which a second tool is mounted to the articulated boom. The construction machine further includes a tool storage for storing the first tool and/or the second tool. The construction machine is configured to replace one of the first tool and second tool when mounted to the articulated boom with the other one of the first tool and second tool when stored in the tool storage.

Motor grader

An excavator includes an articulated boom and a balancing mechanism that assists a movement of the articulated boom from a lower position to an upper position by applying a pulling force on the articulated boom. The balancing mechanism comprises a balancing member that generates an assisting force and a force transfer mechanism that couples the balancing member with the articulated boom. The force transfer mechanism comprises a link mechanism that transfers the assisting force from the balancing member to the articulated boom at a transmission ratio independent from a position of the articulated boom.
