摘要： A frame for a work machine includes a first side wall portion having a first and second bore hole defined therein. The frame further includes a second side wall portion having a third and fourth bore hole defined therein. The first bore hole is linearly aligned with the third bore hole, and the second bore hole is linearly aligned with the fourth bore hole. The frame also includes a central wall portion having a fifth and a sixth bore hole defined therein. The central wall portion is positioned such that the fifth bore hole is linearly aligned with the first and third bore holes and the sixth bore hole is linearly aligned with the second and fourth bore holes. The frame has relatively few parts, lower manufacturing costs, and provides greater visibility to an operator of a work machine on which it is mounted.

摘要： A method of verifying proper coupling of an implement assembly to a lift arm assembly by an operator who is located in a cab of a work machine is disclosed. The work machine includes the implement assembly and the lift arm assembly. The implement assembly includes a hinge plate. The hinge plate has a first coupling aperture extending therethrough. The lift arm assembly has a lift arm and a cylinder. The cylinder is secured to the lift arm. The method includes the step of actuating the cylinder so as to move a pin from a first pin position to a second pin position. The pin is spaced apart from the first coupling aperture when the pin is located in the first pin position. The pin extends through the first coupling aperture when the pin is located in the second pin position. The method further includes the step of viewing the pin when the pin is located in the second pin position by the operator from a position within the cab whereby proper coupling of the implement assembly to the lift arm assembly is verified by the operator without having to exit the cab.
摘要翻译：公开了一种通过位于作业机的驾驶室中的操作者来验证工具组件到提升臂组件的适当联接的方法。工作机器包括工具组件和提升臂组件。工具组件包括铰链板。铰链板具有延伸穿过其中的第一联接孔。提升臂组件具有提升臂和气缸。气缸固定在升降臂上。该方法包括致动气缸以将销从第一销位置移动到第二销位置的步骤。当销位于第一销位置时，销与第一联接孔间隔开。当销位于第二销位置时，销延伸穿过第一联接孔。该方法还包括当销从操作者位于驾驶室内的位置处于销的第二销位置时观察销的步骤，由操作者验证工具组件到提升臂组件的正确联接，而不必退出出租车
