摘要： An apparatus for stabilizing a material handling vehicle which enables or disables a vehicle's suspension system. Pilot-to-open check valves are mounted on hydraulic cylinders secured between the axle and frame of the vehicle. In a first embodiment, a pneumatically actuated check valve is opened or closed to permit or prevent fluid communication between the hydraulic cylinders. The absence of pneumatic pressure in the pneumatic circuit causes the check valves to close, thereby locking the axle to the frame for stability. The presence of pneumatic pressure in the circuit opens the check valves to permit fluid communication between the cylinders. In an alternative embodiment, a second electro-hydraulic circuit is provided in place of the pneumatic circuit for opening and closing pilot-to-close check valves mounted on the hydraulic cylinders.

摘要： A pressure-actuated electrical switch assembly is disclosed which includes a member for dampening the vibration experienced by the contact arm of the switch to prevent undesirable fatigue and breakage. The electrical switch is housed within a dome-like container having an entry port that is connected to a hydraulic circuit. The container is divided interiorly by a diaphragm assembly into upper and lower sealed chambers, the upper chamber having the electrical contacts for the switch and the lower chamber receiving fluid pressure through the entry port. A button actuator is fixed to the diaphragm, and it is movable vertically upward in response to fluid pressure in the lower chamber against the underside of the diaphragm which deflects the diaphragm thereby causing the button actuator to engage the cantilevered electrical contact arm which is mounted in the upper chamber. The cantilevered contact arm is bifurcated into two leg portions, a first of the leg portions being engaged by the button actuator which is attached to the diaphragm. The second leg portion extends in a cantilevered fashion above the first leg portion, and a first contact is mounted at the free end of the movable second leg portion directly above a second fixed contact. A finger-like dampening member is attached at its base and along one of its sides to a cap which encloses the upper chamber. The dampening member engages the second leg portion of the cantilevered contact arm to dampen any vibration experienced by the contact arm. In an alternate form, the dampening member is a physical stop that engages the second leg portion adjacent its free end to dampen vibration.
摘要翻译：公开了一种压力致动的电气开关组件，其包括用于衰减由开关的接触臂经受的振动的构件，以防止不期望的疲劳和断裂。电气开关容纳在具有连接到液压回路的入口的圆顶状容器内。容器在内部由膜片组件分隔成上密封室和下密封室，上室具有用于开关的电触点和下室通过入口接收流体压力。按钮致动器固定到隔膜上，并且可响应于下室中的流体压力而相对于膜片的下侧竖直向上移动，其使膜片偏转，从而使按钮致动器与安装在隔膜中的悬臂式电接触臂接合上室。悬臂接触臂分叉成两个腿部，第一个腿部由附接到隔膜的按钮致动器接合。第二腿部以悬臂方式在第一腿部上方延伸，并且第一接触件安装在可动第二腿部的自由端处，直接在第二固定接触件上方。手指状的阻尼构件在其底部并沿着其一侧附接到封闭上腔室的盖子。阻尼构件与悬臂式接触臂的第二腿部接合以阻尼接触臂经受的任何振动。在替代形式中，阻尼构件是物理停止件，其接合邻近其自由端的第二腿部部分以阻尼振动。

摘要： A coupler assembly for a material handling device is provided which accommodates convenient interchanging of work implements. The coupler assembly includes first and second latching arrangements which are provided on a frame member which is adapted to be mounted on the lift arm assembly of material handling device. Notably, the second latching arrangement includes an elongated bar having end portions which are deflectable with respect to the central portion of the bar. A pair of overcenter locking cams are provided for urging the respective end portions of the bar into recesses defined by hooks which are mounted on the implement to be mounted, thus facilitating convenient attachment of the implement to the lift arm assembly.
