    摘要： A jacking mechanism for leveling a marine platform and a jacket supporting the platform by elevating a tubular leg or member of the platform relative to a pile extending through that member, with the jacking mechanism including a first gripping unit adapted to extend about and releasably grip the tubular member, a second gripping unit adapted to extend about and releasably grip the pile at a location beyond the tubular member and at a diameter smaller than the diameter at which the first gripping unit engages the tubular member, and power actuated means for moving the two gripping units axially relative to one another to cause the desired relative displacement of the leg and pile.

    摘要： A lifting device for raising, lowering and suspending heavy loads comprises a climbing jack with alternating gripping means and a lifting element. For allowing repeated cooperation with the gripping means the lifting element consists of a plurality of outer wire elements and at least one inner wire element, where the elasticity of at least one inner wire element is greater than the elasticity of the outer wire elements. Usually, the outer wire elements are arranged in groups, with spaces between the groups.A gripping device for a lifting element passed therethrough comprises a double-acting piston within a cylinder, with a plurality of jaw elements therein. The jaw elements are wedge shaped at their side remote from the lifting element, and are held between pairs of guides formed in the cylinder for radial movement only. The piston carries correspondingly wedge-shaped elements, so that longitudinal movement of the piston results in radial movement of the jaws.

    摘要： Apparatus for raising and lowering a heavy weight such as working platform along a column which also may raise and lower the column in the floating condition of the working platform in the same efficiency as the operation in the working platform. To this end, the apparatus is so constructed that main cylinder for raising and lowering the working platform and column is always actuated to push out the associated piston rod for moving the working platform or the column.

    摘要： Apparatus for raising and lowering a platform on an upright column comprising a pair of vertically spaced ring assemblies, each comprising an outer support ring and an inner ring which can be wedged between the support ring and the column to anchor the support ring against displacement on the column. The surfaces of engagement between the support ring and the clamping ring are tapered upwardly and hydraulic actuators are provided for displacing the rings independently of one another along the column. These actuators are connected at one end to an element in one ring assembly and are effectively connected at the other end to an element in the other ring assembly so that each element in the ring assembly is free to be displaced longitudinally of the column independently of the other element.
