    摘要： Provided is a hybrid-type construction machine including a swing device of the hydraulic-electric combined swing type and by which, in a work for which accurate swing operability is demanded like, for example, a crane work, a swing body is driven alone by the electric motor.The hybrid-type construction machine includes an engine, a hydraulic pump driven by the engine, a swing body, an electric motor for driving the swing body, and a hydraulic motor driven by the hydraulic pump for driving the swing body. The swing body is swung by simultaneous drive by the electric motor and the hydraulic motor. The hybrid-type construction machine includes a control apparatus having a work mode changeover unit by which an operator changes over a mode in response to an aspect of a work and an electric alone swing controlling unit configured to control the swing body to be swung by the electric motor alone. When a work in which position accuracy is demanded is selected by the work mode changeover unit, the swing body is swung by the electric alone swing controlling unit.

    摘要： A self-propelled work machine includes an undercarriage provided with drive wheels driven by a drive device. An upper structure is rotatably mounted on the undercarriage. A drive unit is arranged in the undercarriage and a boom for a work tool is mounted on the undercarriage. The drive unit drives a power generator that is a power source for an electric motor arranged in the upper structure, the electric motor being the drive device for the drive wheels arranged on the undercarriage.

    摘要： A load lifting vehicle particularly an endless track crane comprises a support chassis which is centrally arranged between a travelling gear frame on each side thereof. The travelling gear frames are supported by respective support beams on each side of the chassis which are telescopic within the central chassis and which are connected to the respective gear frames. Two support beams may be provided on each side of the chassis which are arranged either so that they are offset from the beams on the other side or they are in alignment with the beams on the other side and telescoped within the chassis up to an intermediate central point. To provide for maximum contraction and lateral extension of the travelling gear frames for varying the wheel base or track bases, the travelling gear frames are advantageously provided with through openings so that the supporting beam for the travelling gear frame on the opposite side may be telescoped completely through the central changes and through an opening of the gear frames to project beyond the opposite side of the gear frames if desired during contraction of the base.
