Abstract: A rack and a hoist system. The rack is L-shaped with a first planar floor/leg and a second planar floor/foot, which is a solid plate. The first floor has three pairs of wheels with the middle pair larger than the other pairs and a mount to couple to the hoist via a hooked line that couples to a double-hooked line that hooks into apertures through paired mounting plates near the top end of the leg. The foot includes a tag-line mount from which a tag-line may be mounted to help guide movement thereof using the hoist. The foot includes wheels such that when the first floor is tipped up while being lifted, the wheels of the foot engage with the surface while the wheels on the leg are disengaging. There are flanking posts, strap structures, and flanking plates that help to secure the load (e.g. rebars, pipes, and sheet rock).
Abstract: A method and manufacturing system for producing prefabricated parts of mineral-bound building materials, in particular for construction of buildings is disclosed. The manufacturing system includes at least one formwork table provided for casting the prefabricated parts of mineral-bound building materials as the essential component. The manufacturing system is mobile and it can be brought to the site of use of the prefabricated parts and in particular to the erection site of a building for manufacturing the prefabricated parts. Thus, this mobility allows transporting a complete small factory for manufacturing prefabricated parts of mineral-bound building materials to very different locations.
Abstract: A crane comprising a horizontally extending frame having a longitudinal axis, the frame being supported above the ground for horizontal movement generally perpendicular to the longitudinal axis; a trolley supported on the frame for movement generally along the longitudinal axis; a mechanism for engaging and disengaging a load; a hoist mounted on the trolley for causing vertical movement of the mechanism; and a carrier connected to the frame for movement with the frame, the carrier being positioned such that the trolley, hoist and mechanism are operable to deposit a load in the carrier.
Abstract: A crane vessel (20) has a temporary load support structure (23) on which to support a load (22) in transit. For installation, the load is hooked up to the vessel crane (21) and the temporary support structure is removed to enable the vessel to set down the load on its tower structure (24).
Abstract: The invention relates to a device for a recovery vehicle of the type comprising rear, lowerable supporting stifflegs (5) and a crane boom (1) which turns about a horizontal axis (11) and has a boom foot (2) and a folding boom (3) with an extension (4) thereon. According to the invention the crane boom is placed on a turntable or the like on the vehicle. The turntable and consequentially the crane boom can be turned about a vertical axis of rotation. In order that the boom foot, which during transport preferably is arranged between a pair of lowerable rear stifflegs, should be unobstructed by these stifflegs or other obstacles, the crane boom is longitudinally displaceable relative to the turntable, according to a preferred embodiment.
Abstract: Cargo containers are moved between a dock and a ship by a crane which has a vertically movable landing platform, a waterside trolley for moving cargo between the ship and the landing platform, and a landside trolley for moving cargo between the dock and the landing platform. The landing platform is moved to different elevations to change the extent of vertical movement performed on the cargo by each of the tolleys. In the course of operations, the landing platform is movable to an elevation which corresponds approximately to the higher of: (a) the elevation of the designated location on the ship where the article of cargo is to loaded or unloaded, or (b) the elevation of the highest obstacle between the dock and the designated location; and, both trolleys are operated while the landing platform is at this elevation.
Abstract: A mobile maintenance stand for servicing and transporting ejection seats utilized in aircraft includes a mobile platform having disposed thereon upright arms adapted to encompass an ejection seat and rotatable to expose the various portions thereof for servicing and maintenance of the wiring, electronics, etc. disposed therein. The platform is rotatable 360 degrees in a horizontal plane with the upright arms rotatable 270 degrees in a vertical plane and is mounted on a lower portion provided with wheels disposed at the distal ends of outwardly extending arms. The arms may be extended to provide additional stability and removable screw jacks are attachable on the arms to provide a rigid stable platform. Additionally included on the rotating base platform is a removable telescoping crane assembly that may be attached to an ejection seat disposed in an aircraft for removing the seat therefrom and placing it in position to be retained by the pair of servicing arms.
Abstract: A floating crane whose floating base mounts a load boom with a load-handling device and a suspended-load reslinging device, the latter comprising a catch so mounted on the floating base as to project over the board thereof while in the load reslinging position, and a tie member carrying at one of its ends its own load-handling device and being adapted to successively link to the load-handling device of the load boom and to the catch in the course of load reslinging procedure.
