摘要： A method of pumping liquid from a container to a destination comprises the steps of connecting a foot operable air pump in sealed air-delivery relation to the container; connecting a liquid delivery hose in sealed liquid receiving-relation to the container at the aperture such that the inlet end of the liquid delivery hose is submerged in liquid in the container, the liquid delivery hose having a hand operable valve for controlling the flow of the liquid through the liquid delivery hose; and operating the foot operable air pump by a foot, so as to pump air into the container, and operating the hand operable valve by a hand, so as to cause the liquid to flow from the container, through the liquid delivery hose, and to the destination. A related system, fitting, and adapter are also disclosed.

摘要： The invention provides a retractable cover apparatus, which when extended to cover the wheel or track area of a variety of vehicles minimizes the amount of spray and debris flying from the tires or tracks of the vehicle. The cover system is mounted to the frame of a vehicle without requiring extensive modifications to the frame, and includes, for each side of the vehicle, an elongated flexible cover having first and second ends and a width sufficient to extend laterally outwardly beyond an outer extent of the wheels or tracks of the vehicle. The cover system also include at least first and second cover housings, one of the housings adapted to contain the cover in a rolled retracted condition and the other housing being adapted to anchor a free end of the cover in an extended condition thereof. At least one support bar is removably mounted to the frame of the vehicle over which the cover is supported. When the cover is required, it is pulled from the one cover housing, over the support bars and is anchored in place at the other cover housing.

摘要： A mobile load support for cradling and moving heavy loads comprises a pair of axles in spaced apart parallel relationship to each other, having corner units pivotally mounted on respective ends of the axles. Each of the corner units comprises a truck body having swivelable castor wheels disposed at each end thereof, and a platform projecting therefrom at a level below the longitudinal axis of the truck body for cradling a corner of the load. A pair of ratchet straps engages the ends of the axles, and can be tightened to secure the mobile load support around the load. The mobile load support is capable of manoeuvring over uneven surfaces due to the pivoting action of the corner units, which reduces the tendency of the load becoming dislodged from the support, and is flexible in that it can be easily adapted to loads of different sizes.
摘要翻译：用于起重和移动重载荷的可移动负载支撑包括彼此间隔开的平行关系的一对轴，其具有枢转地安装在轴的相应端部上的角部单元。每个拐角单元包括一个卡车主体，其具有设置在其每个端部的可旋转的脚轮，以及从卡车主体的纵向轴线下方突出的平台，用于托起负载的角部。一对棘轮带接合轴的端部，并且可以被紧固以将移动负载支撑件固定在负载周围。由于角部单元的枢转作用，移动式负载支撑能够在不平坦的表面上操纵，这降低了负载从支撑件移出的趋势，并且是柔性的，因为它可以容易地适应于不同尺寸的负载。
