Abstract: The invention is a lifting device for use in lifting a load. The device is used for example between a crane hook and the lifting chains attached to the load. The device hooks onto the crane hook and the chain passes over a guide wheel which in one position, when the chain does not take the weight of the load, the wheel can turn freely enabling the device to be moved horizontally relative to the load to any desired location, and when the chain does take the load, the wheel is placed in a locked position so that it cannot turn and by this means the device can be positioned so as to ensure that when the load is lifted it will be in a predetermined position e.g. level. The wheel is carried by a spindle, the ends of which pass through slots in a pair of side plates of the device and when the device is loaded, the spindles rest on the bottoms of the slots ensuring that the plates take the load.

Abstract: A method of transporting bagged cargo is disclosed. The method comprises the steps of placing elongated bags on a strap with the transverse midline of each bag aligned on or over the strap. The strap is then fastened around the sides and over the top of the bags, therefore forming a matrix.

Abstract: Continuous filament rope and method of making same whereby high strength continuous synthetic filaments may be used to provide a rope which in use will have a strength approaching the theoretical strength of the fibers therein. The rope is made by combining a plurality of filaments and twisting the filament group into a light twine in comparison to the rope ultimately desired.

Thereafter the loop is allowed to twist back on itself in response to the twist initially set in the twine so as to form a rope-like center section with loops at each end thereof. Curing of the flexible resin system results in a suitable flexibility of the rope while providing for abrasion and fraying resistance. The loops at the end of the rope may be looped over hooks or pins when in use, with the resulting strength of the rope approaching that of the combined fiber strength.
