A mobile-type maintenance square-shaped bin including a bin body, a travelling mechanism provided under the bin body, a car head connected with one end of the bin body, an inlet and an outlet provided at the other end of the bin body, a sealed door provided on the inlet and the outlet, an allocation and transportation device mutually connected with a microcomputer signal provided at a front end of the bin body as well as provided over an internal portion of the bind body, an maintenance platform provided at a bottom of the internal portion of the bin body, a tool platform provided adjacently to the maintenance platform, an ash-removal mechanism provided at an upper portion of the maintenance platform, an air-conditioning device provided at an outer portion of the bin body, and a scanning mechanism provided at a front portion of the maintenance platform.

A mobile crane including a frame which, in its upper part, is provided with a main support structure and which, in its lower part and on opposite sides of the lower part of the frame, is provided with lower beam structures transverse to the main support structure, and upright legs between the main support structure and the lower beam structures; at least one wheel or wheel arrangement at both ends of the lower beam structures, i.e. in each lower corner of the crane; a trolley arranged to move along the main support structure and provided with a hoisting member; at least one hoisting mechanism; at least one rope drum arranged to be run by the hoisting mechanism; and at least one rope arranged from the rope drum of the hoisting mechanism to the hoisting member for running it, the rope drum being further provided with at least one hoisting rope connected to at least one counterweight.

An apparatus includes a height-adjustable gantry assembly configured to be securely connected to a gantry load resting on a working surface. The height-adjustable gantry assembly, in use, lifts and supports the gantry load vertically above the working surface. A movable frame assembly is configured to move and support the height-adjustable gantry assembly.

A system for transferring loads from a mobile robot device. The system includes a transportable conveyor platform. The mobile robot device transports the transportable conveyor platform to/from a lift mechanism. The lift mechanism lifts the transportable conveyor platform and any load thereon from the mobile robot device and to a desired height for unloading the load.

Facilities for processing steel. One facility includes a line for producing packages; a plurality of stackable cassettes for receiving packages; a splitter subfacility; automated transfer apparatus; and an automated overhead crane. The line may be a slitting line with the packages being coils of steel, or a cut-to-length line with the packages being stacks of steel sheets. A premises of the facility comprises a loading area in which packages from the line are loaded into cassettes, a storage area in which cassettes are stored, and a transition zone including at least one transfer position. The automated transfer apparatus moves packages and/or cassettes between the transfer position and the splitter subfacility. The automated overhead crane moves cassettes between the storage area, the loading area, and the transition zone.

A jacking tower installation system comprises a jacking tower having at least two forward and at least two rear legs, wherein each of the legs is supported on one of a plurality of support stands attached to and horizontally offset from the leg, the legs including dollies which enable horizontal movement of the jacking tower and lifts capable of raising and lowering the jacking tower clear of the sill beams of a cargo container crane, such that the legs of the jacking tower can be lifted and positioned over and lowered onto the sill beams.

A hoist tool for handling a shrink element of a gear system. The hoist tool includes a suspension section, support legs for leaning on a foundation structure of the gear system and for supporting the suspension section to be above the shrink element, a lift sling for surrounding the shrink element, and a force generating system between the suspension section and the lift sling and suitable for generating a lifting force on the lift sling so as to suspend the shrink element. During maintenance of the gear system, the weight of the shrink element can be compensated for with the hoist tool and therefore crane capacity is needed for compensating for only the rest of the weight of the gear system without the weight of the shrink element.

The present disclosure provides an aircraft security door as well as methods, systems and apparatus for handling an aircraft security door. In one implementation, a method for installing an aircraft security door onto an aircraft is disclosed. The method includes transferring the aircraft security door to an aircraft service stair, supporting the aircraft security door by a bridge crane coupled to the aircraft service stair, positioning the aircraft service stair in proximity to a fuselage of the aircraft adjacent to an opening in the fuselage, positioning the aircraft security door relative to the opening using the bridge crane, and securing the aircraft security door to the opening.
