A hoist for transferred materials in an underground auxiliary transportation system and a method thereof. The hoist includes a hoist body, guiding plates mounted at two ends of the hoist body through bolts, twist locks mounted at four ends of the hoist body, a driving unit configured to drive twist locks to rotate, transmission assemblies configured to connect the twist locks with the driving unit, ejector pins configured to prevent the twist locks from rotating mistakenly, and a sensor configured to control the hoist to operate and provide protection safety.

A high-precision positioning system for a monorail hoist in a mine includes two gear carriers symmetrically arranged on both sides of an I-beam track. Each of the gear carriers includes a positioning wheel and a plurality of travelling wheels. The travelling wheels are travelling on an upper end face of a bottom plate of the I-beam track, and the positioning wheel is in engagement transmission with a rack at a lower end of the bottom plate of the I-beam track. The gear carriers include an installation bracket and a connecting seat configured to connect the monorail hoist. The installation bracket includes an inertial measuring unit and a single-chip microcomputer that are electrically connected with each other. The positioning wheel includes a rotation angle sensor and the rotation angle sensor is electrically connected to the single-chip microcomputer. A headstock at both ends of the monorail hoist includes a coordinate updating unit.

A load assembly for use with an aircraft includes a support sub-assembly and a lifting sub-assembly. The support sub-assembly is configured for removable coupling to a structural member of the aircraft. The structural member has a first interior position and a second interior position. The support sub-assembly extends between the first interior position and the second interior position. The lifting sub-assembly is movably coupled to the support sub-assembly. The lifting sub-assembly is movable along the support sub-assembly between the first interior position and the second interior position and configured to lift or lower a load, and to support the load as the lifting sub-assembly moves along the support sub-assembly between the first interior position and the second interior position.

An overhead transport vehicle includes a container accommodation portion sandwiched by a pair of cover portions in a front-and-rear direction in a traveling direction and configured to hold a cassette in a state in which a lid faces in a width direction intersecting the traveling direction and a vertical direction; and a lid-fall prevention member on the cover portion to prevent the lid that has come off from the cassette held in the container accommodation portion from falling. The lid-fall prevention member includes a lower support portion extending along the width direction below the cassette and partially protruding from the lid in a planar view seen from the vertical direction, and a front support portion standing upright in the vertical direction from the lower support portion so as to face at least a portion of the lid. The lower support portion and the front support portion are integrally defined by a unitary structure.

A rope hoist includes: a rope drum around which a wire rope can be wound; a drum motor for rotating the rope drum; a reduction gear mechanism reducing the rotation of the drum motor and transmitting the rotation to the rope drum; and a control unit controlling driving of the drum motor. The reduction gear mechanism is arranged inside a wall portion provided by being projected from a motor cover of a main body part which is an end frame member supporting the rope drum, a lead wire extended from the drum motor and a cable extended from the control unit are connected via a relay, and the relay is arranged on the outside of the wall portion surrounding the reduction gear mechanism, and housed inside a recess provided on the motor cover.
