    摘要： Typical loading machines utilize a pair of lift arms to mount a work implement to a machine frame. The spacing of the lift arms and the tilt linkage mounted to the lift arms to manipulate the work implement reduce the visibility to the work implement as well as increase the overall weight of the structure. The present invention provides a boom-type lift arm that has a non-clevised configuration on both end portions thereof that mount a work implement to the frame of a machine. The tilt linkage is mounted between the lift arm and the work implement to rotate the work implement with respect to the lift arm. The work implement defines a pair of mounting plates that mount both the tilt linkage as well as the lift arm.

    摘要： In the operation of a wheel loader the linkage arrangement that mounts the bucket to the machine often utilizes multiple lift arms and tilting components to accommodate the loading encountered in the various excavation operations. In many instances this hampers visibility to the bucket and also greatly increases the overall weight of the linkage arrangement. The present invention provides a linkage arrangement that utilizes a single boom-type lift arm and a tilting arrangement that is substantially centered along a vertical plane in which the linkage arrangement is moved. In addition, the individual components of the linkage are specifically contoured to provide a sufficient amount of mass in critical areas of loading and reduced areas of mass in non-critical areas. The result is a linkage arrangement that provides excellent visibility to the bucket with greatly reduced overall weight.

    摘要翻译： 在轮式装载机的操作中，将铲斗安装到机器上的联动装置通常利用多个提升臂和倾斜部件来适应各种挖掘操作中遇到的负载。 在许多情况下，这阻碍了铲斗的可见性，并且还大大增加了联动装置的总重量。 本发明提供了一种联动装置，其利用单个起重臂型提升臂和倾斜装置，所述悬臂式提升臂和倾斜装置沿连接装置移动的垂直平面基本上居中。 此外，联动装置的各个部件具有特殊的轮廓，以在非关键区域的关键加载区域和质量区域提供足够的质量。 结果是一种联动装置，其大大降低了整体重量，提供了对桶的极好的可视性。

    摘要： A vehicular power shovel having its movable shovel member located forwardly of the front axle thereof is equipped with a toggle lever device and a hydraulic power cylinder mechanism for actuating the shovel member. The shovel member is mounted upon a lift arm structure which is pivotally mounted upon the frame of the apparatus at a point behind the front axle. Both the toggle lever device and the hydraulic power cylinder mechanism are pivotally attached to the frame of the apparatus and are located behind the front axle. The power cylinder operates to actuate the toggle lever device and it is connected thereto at a point other than the buckling joint of the toggle lever. Furthermore, the power cylinder is located rearwardly of the point at which the rear end of the lift arm mechanism is pivotally connected to the frame.

    摘要： A material handling device having a bucket pivoted on the free ends of lift arms that extend on opposite sides of a vehicle body and are pivoted on uprights extending from the body adjacent the rear end thereof. The material handling device incorporates pivot means for tilting the bucket and automatically maintaining the bucket in a level condition as the lift arms are raised. The pivot means includes a pair of links that are supported within the hollow lift arms with a fluid motor located between one of the links and the material handling implement that is pivoted on the free end of the lift arms. The links and hollow lift arms are constructed and arranged to allow unrestricted movement of the links within the lift arms while the lift arms are pivoted between raised and lowered positions.
