Abstract: A rigid frame riding on tracks carries forwardly directly lift arms pivoted to towers at the central portion of the vehicle. The engine is disposed over the rear track sprocket axis and is spaced rearwardly from the lift arms providing for an operator''s compartment which is between the engine and the arms and which overlaps the front of the engine. Fuel and hydraulic tanks are shaped to conform with the region below the lift arms when the arms are in the lowered position. The construction provides a weight distribution facilitating load handling and provides an operator station combining good visibility, easy access and safety.
Abstract translation: 骑在轨道上的刚性框架向前直接提升臂，枢转到车辆中心部分的塔楼。 发动机设置在后履带链轮轴线上并且与提升臂向后间隔开，从而提供在发动机和臂之间并且与发动机前部重叠的操作者舱室。 当臂处于降低位置时，燃油箱和液压油箱的形状适合提升臂下方的区域。 该结构提供了便于负载处理的重量分配，并且提供了具有良好的可视性，易于接近和安全的操作台。

Abstract: In axial-piston, hydraulic pumps and motors, the thrust loadings of the pistons on their bearing supports vary proportionally to pressures in the unit and also circumferentially around the bearing supports. By employing hydrostatic button bearings pressurized in ''''sets'''' around the bearing support with at least one set pressurized with the unit''s inlet pressure and another ''''set'''' pressurized by the unit''s outlet pressure, improved bearing performance is achieved. Also, certain surface configuration forming the sills and recesses of the individual buttons can enhance bearing performance.
Abstract translation: 在轴向活塞，液压泵和电动机中，活塞在其轴承座上的推力载荷与单元中的压力成正比，并且在轴承支撑件周围也是周向变化的。 通过采用以“套”方式加载的静压按钮轴承，其中至少一个设备以单元的入口压力加压，另一个由设备的出口压力加压的“套件”，可实现改进的轴承性能。 此外，形成各个按钮的窗台和凹部的某些表面构造可以增强轴承性能。

Abstract: A relatively low pressure hydraulic control system for a high pressure work output system in which a control valve is selectively actuated to position a variable displacement axial piston pump to control the flow in the work output system and to position a directional valve which controls the direction of work output. In such a system wherein two work outputs are provided, thereby requiring two control valves, a priority valve may be utilized in the low pressure system so that a signal from one of the control valves will always override a signal from the other control valve in controlling the axial piston pump.

Abstract: A check valve that has an orifice formed by a groove in its face which communicates with the upstream and downstream sides of the valve so as to allow restricted flow through the valve when it is closed, and wherein upon opening of the check valve, foreign material which may have lodged in the orifice is flushed out by the fluid flowing through the valve.
