Abstract: A portable ramp assembly and method of construction provides a ramp assembly with a pair of side rails and a plurality of panels adapted for releasable attachment to the side rails. The panels have an upper support surface and a like lower support surface facing opposite the upper support surface. The panels are individually removable from the side rails to interchange the upper and lower support surfaces.

Abstract: A portable floor surface and method of use thereof facilitates unloading side-by-side cargo carts disposed in laterally spaced relation with an aisle defined between them. The floor surface has a body with opposite front and rear ends and lower and upper surfaces extending between the front and rear ends. The upper surface is brought into a generally flush relation with the floor of the cargo cart when the lower surface is resting on a common floor surface with the cargo cart. A ramp surface extends at an upward inclination from the front end toward the rear end and a latch member operably associated with the body is adapted for operable engagement with a first cargo cart to releasably lock the portable floor surface to the first cargo cart.

Abstract: A brake system operable to inhibit movement of a non-powered transportable cart. The cart has a platform with opposite front and rear ends, at least one pivotal caster wheel adjacent and supporting one of the front or rear ends, and a pair of fixed wheels. The brake system has a brake arm with a brake bar extending laterally therefrom. The brake arm is pivotal between a disengaged position and an engaged position. When in the disengaged position, a gap is defined between the brake bar and the fixed wheels to allow the fixed wheels to rotate freely. When in the engaged position, the brake bar engages the fixed wheels to prevent them from rotating. A brake latch is carried by the platform and has a catch sized to receive the brake arm to releasably maintain the brake arm in its engaged position.

Abstract translation: 一种制动系统，其可操作以禁止非动力输送车的运动。 推车具有相对的前端和后端的平台，至少一个枢轴脚轮相邻并支撑前端或后端中的一个以及一对固定轮。 制动系统具有制动臂，制动杆横向延伸。 制动臂在分离位置和接合位置之间枢转。 当处于分离位置时，在制动杆和固定轮之间限定间隙，以允许固定轮自由旋转。 当处于接合位置时，制动杆接合固定的车轮以防止它们旋转。 制动器闩锁由平台承载并且具有尺寸被设计成接收制动臂的卡扣，以将制动臂可释放地保持在其接合位置。
