Abstract: A dock leveler having a deck-assembly, a first hydraulic cylinder to power said deck assembly to a raised position, lip mounted to said deck assembly, and a second hydraulic cylinder for powering said lip into an extended position. An hydraulic power circuit is coupled to the first and second hydraulic cylinders to control movement of said deck and lip. The hydraulic power circuit includes a pump to deliver fluid under pressure, a first valve operatively coupled to the pump to control fluid flow to the first hydraulic cylinder. A second valve is operatively coupled to the second hydraulic cylinder. An adjustable relief valve is coupled to the second valve to prevent a reduction of fluid pressure to the second hydraulic cylinder after the pump has supplied fluid under pressure through the second valve to extend the lip.

Abstract: A barrier for a loading dock having an opening in a wall having a dock leveler positioned in a floor of the loading dock adjacent said opening. The dock leveler has a horizontal position where traffic may cross to adjacent areas of the loading dock. A support is located along a side of the dock leveler. A deformable barrier arm is pivotedly connected to the support by a mounting for movement between a horizontal blocking position and a raised vertical position exposing the opening. The mounting has a pivotal connection to the support to permit the deformable barrier arm to move in a vertical arc for raising and lowering the arm and a loose connection to the barrier arm to permit relative motion between the barrier arm and the mounting upon the application of a horizontal load to the barrier arm.

Abstract: A hold-down device for a mechanical dock leveler which is spring loaded so that when the hold-down device is released the deck will rise and the lip will extend. When the deck is walked down, the hold-down device maintains the deck in contact with the truck bed. This is accomplished by means of the interaction and geometry between a brake actuating arm and a brake release arm and the associated pins. As the dock leveler is lowered, the perpendicular distance from an anchor pin to the center line of a slot in the brake actuating arm increases. This causes the brake actuating arm to move upward increasing tension on the brake band. The brake release arm moves and increases the braking force. As the dock leveler is raised the braking force is reduced. The leveler includes a two-stage safety leg with a guide bar attached to the safety leg stop. The guide bar limits free travel of the safety leg. The guide bar engages projecting tabs from each stage of the safety leg to require upward or free movement above a respective engagement position before the safety leg can move forward and re-engage the stop.

Abstract translation: 用于机械平台矫直机的压紧装置，其是弹簧加载的，使得当压紧装置被释放时，甲板将上升并且唇缘将延伸。 当甲板走下来时，压紧装置保持甲板与卡车底座接触。 这通过制动器致动臂和制动器释放臂与相关销之间的相互作用和几何形状来实现。 当船坞平整机降低时，从锚定销到制动执行臂中的槽的中心线的垂直距离增加。 这使得制动器致动臂向上移动增加制动带上的张力。 制动释放臂移动并增加制动力。 随着平台矫直机升高，制动力降低。 矫直机包括一个两级安全腿，带有连接到安全腿部的导杆。 导杆限制了安全腿的自由行程。 引导杆从安全腿的每个阶段接合突出片，以在安全腿向前移动并重新接合止动件之前要求在相应的接合位置上方向上或自由运动。

Abstract: A brake mechanism for a vertically storing dock leveler mounted on a carriage for lateral movement on rails relative to a dock surface. The brake is automatically actuated by means of an arm that bears against the leveler. When the leveler is lowered the arm rotates to urge a brake member into engagement with a rail thus preventing lateral movement of the carriage and leveler.

Abstract: A dock leveler having a rigid flat deck and a rigid hinge pin coupling the leveler to a loading dock or leveler frame element. The deck is supported by a series of spaced box beams, each one split longitudinally to provide the necessary torsional flexibility to allow a rigid hinge pin. The use of a box beam geometry still serves to provide the required load support for the deck.

Abstract: An improved dump mechanism for a toy truck includes a dump lever having an upper surface curving downward toward the lifting end of the dump lever to engage an undersurface of the dump body. The curved surface of the dump lever is shaped for pivoting the dump body in increments that increase successively relative to corresponding successively equal pivotal increments of the dump lever throughout at least the initial half of the motion of the dump body from a load position to a full-dump position. This makes the pivoting of the dump body with the dump lever relatively easy with approximately even torque on the dump lever throughout the dumping motion.
