Abstract: A an energy storage system includes a crane and a plurality of blocks, where the crane is operable to move blocks from a lower elevation to a higher elevation (via stacking of the blocks) to store electrical energy as potential energy of the blocks, and then operable to move blocks from a higher elevation to a lower elevation (via unstacking of the blocks) to generate electricity based on the kinetic energy of the block when lowered (e.g., by gravity). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the power grid.

Abstract: A supporting framework for a craneway for at least one crane which travels on at least one track, especially for a bridge crane which travels on two tracks, includes a track carrier elongated in a track direction and having at least one carrier section of reinforced concrete, preferably of prestressed concrete. A system of pillars includes reinforced concrete pillars, whose upper ends in each case support the carrier sections via a top component and whose lower ends are in each case anchored in the soil via a base component. An adjustable bearing in the area of the top component and/or of the base component in at least some of the pillars allows adjusting the track carrier according to the desired course of the track.

Abstract: A extendible boom incorporates a locking mechanism that mechanically engages an extended boom section in response to the loss of hydraulic fluid pressure to the lift cylinder for that boom section so as to prevent unintended boom lowering. The locking mechanism includes locking devices, such as toothed cams, that are located on opposite sides of the boom and that are configured to move, 1) from a disengaged position permitting unobstructed movement of the extended section relative to the adjacent section, 2) to an engaged position in which the locking devices engage opposite sides of the extended section to prevent unintended boom lowering.

Abstract: A portable, collapsible engine support apparatus. The device is attachable to the fender or firewall of the vehicle and is mountable either transversely or longitudinally above the engine compartment. A pair of primary load bearing metal angles are secured on opposite sides of the open engine compartment on either the fender or firewall. A pair of upstanding posts approximately centrally positioned on the upward facing surface of the angle, each of the upstanding posts including connection means adapted to lockingly receive horizontal support bars. A central connector allows for adjustment of the spacing between the metal angles. A flexible, adjustable attachment means depends from the central connector, the attachment means adaptable for engagement with the main engine hold. Adjustment of the attachment means to a desired tension ensures a high degree of positional stability of the engine when performing major repairs.

Abstract: A tubular post is erected from a retracted position in the deck of a load receiving ship to accommodate load transfer operation. A highline connection established by an automated rigging technique substantially reduces manpower requirements, with all receiving station equipment stowed below deck for watertight integrity and to minimize radar cross-section.

Abstract: An improved method of lifting a load includes supporting a load on a first section of an extendible lift assembly, the first section being surrounded by a second section, a hydraulic cylinder being operatively coupled to the first section so as to be capable of lifting the first section, and the first and second sections being supported on and vertically extendible with respect to a base. Then, while the load is supported on the first section, the hydraulic cylinder is extended to extend the first section relative to the second section and the base, thereby lifting the load to a first height. Then, the first section is secured to the second section so as to at least substantially prevent downward movement of the first section relative to the second section. The cylinder is then retracted and operatively coupled to the second section.

Abstract: A hydraulic boom gantry and a method of lifting a load associated therewith. The gantry includes telescoping sections with a hydraulic cylinder mounted therein. A swiveling plate structure allows minor deviation between sets of telescoping sections. A collar structure and a pinning structure lock the telescoping sections together. A cam mechanism prevents accidental section retraction and a powered rigging device traverses a beam connecting the telescoping sections.
