摘要： A heavy duty hydraulic shock absorber having an inner tube in which is slidably mounted an impact receiving piston assembly. Upon application of an impact force on the piston assembly, the piston assembly is moved inwardly of the inner tube and fluid from the inner tube is metered through a plurality of exponentially disposed metering orifices into an accumulator chamber formed between the inner tube and an outer tube which encloses the inner tube. An adjustable, slidable metering spool is operatively mounted in the accumulator chamber, over the metering orifices, for regulating the flow of fluid through the metering orifices into the accumulator chamber.

摘要： Crane bumper containment sleeves are disclosed. An example apparatus includes a flexible sleeve to contain a bumper of a crane. The flexible sleeve includes a first end to be closed adjacent the bumper to contain the bumper in a cavity defined by the flexible sleeve. The first end of the flexible sleeve and the bumper are to couple to a first position of the crane via a fastener. The flexible sleeve includes a second end opposite the first end. The second end is to couple to a second position of the crane to prevent the bumper contained in the cavity from falling from the crane if the first end of the flexible sleeve decouples from the first position of the crane.

摘要： Apparatus for limiting a travel path of running gears, in particular hoists, traveling along a running rail of a type having at least one flange and a web, includes a pair of side elements which are securable to opposite sides of the flange and provided with at least one buffer, and a clamping unit in the form of a tie element, for bracing the side elements together and pressing the side elements against the sides of the flange. In order to permit the travel path limitation apparatus to be useable above as well as below the running rail, the side elements have a first pair of aligned throughholes and a second pair of aligned second throughholes oriented parallel to the first pair of throughholes, whereby the tie element extends through the first pair of throughholes of the side elements in a first attachment position of the side elements and extends through the second pair of throughholes of the side elements in a second attachment position in which the side elements are rotated in a vertical direction by 180°. The side elements are urged against one of the flange surfaces by tensioning members which bear upon the flange, whereby support members, positioned in the side elements, support the tensioning member.

摘要： The disclosed invention relates to a force-absorbing member which is formed of a resilient plastic material having a relatively high tensile strength mounted in a suitable restraining member. The force-absorbing member includes an annular mounting flange which is of sufficient size and the material of the force-absorbing member of sufficient strength to permit the force-absorbing member to readily deflect to one side of its axis during use, and the mounting of the flange is such that the flange will not rupture or pull through the member restraining it against movement. The force-absorbing member may be utilized, inter alia, as a bumper per se, as a support for a bumper, as a combined boat rub-rail and line-attaching member, or as part of a shock-absorbing unit of a tow unit, such as a tow chain.

摘要： This invention relates to an apparatus for absorption of mechanical energy, particularly energy of very strong shocks. It comprises an immobile cylinder and, inserted in it in telescopic fashion, a mobile part consisting of at least one mobile cylinder with a bottom and a mobile plunger inserted into the last cylinder, the empty space between the cylinders and between the last cylinder and the plunger being filled with a medium absorbing energy of shocks and vibrations and being characterized by viscous flow in static state and by high elasticity in dynamic state. Any of the mobile cylinders is provided with a plunger and a baffle dividing the cylinder into two chambers, one chamber being filled with a visco-elastic medium absorbing mechanical energy, and the other chamber being filled with a visco-elastic medium compressed to a pressure higher than 1000 h Pa.

摘要： The shoe derailment device for use in derailing a conductor shoe assembly of a bridge crane from a conductor rail assembly generally has a wedge head provided at a longitudinal end of a body made of an electrically insulating material, the shoe derailment device being securable to the conductor rail assembly in a derailment position in which the shoe derailment device is positioned outside an operating zone of the bridge crane, with the wedge head facing the operating zone in a manner that if the conductor shoe assembly is moved outside the operating zone, into the area occupied by the shoe derailment device, the conductor shoe assembly is derailed from the conductor rail assembly as the conductor shoe assembly engages the wedge head and is maintained in a derailed state by the electrically insulating material when the conductor shoe assembly is engaged with the body.
