A carriage (11) has a carriage body (12) to extend across the top face of a track. A fixed bearing arrangement (14) includes a bearing (15a, 15b) to engage a first side of the track and having a rotational axis located in a fixed position on the carriage body. A self-adjusting bearing arrangement (19) includes a movable bearing (20) to engage a second side of the track and mounted on a pivot arm (21) having a pivotal connection (24, 25) with the carriage body. A bias spring is arranged to act on the pivot arm such as to maintain contact between the movable bearing and the second side of the track. The movable bearing (20) is not driven. The movable bearing (20) and the pivotal connection (24, 25) of the pivot arm (21) are both located at a first end of the pivot arm. The bias spring is spaced from the pivotal connection (24, 25) in a first direction. The movable bearing (20) rotates about an axis which is offset from the pivot axis of the pivot arm in a second direction which is transverse to the first direction. Such spacing in the first direction is between five and twenty times the spacing in the second direction.

A connection adapter for a connection of profile segments of a rail profile in a conveying device for conveying hanging objects. The connection adapter has, on its inside, a running surface for the mounting of holding adapters mounted such as on rollers, where the running surface is disposed in an inclined manner with respect to a profile extension direction of the connection adapter in such a way that a cross-section of an inner space of the connection adapter, which is defined by the running surface, is larger at a first end face of the connection adapter than at a second end face of the connection adapter.

A monorail transportation-based spatial transport system, comprising a load-bearing frame system or a load-bearing pier system. The load-bearing frame or pier system divides, by means of bent caps, the spatial transport system into at least two layers (K1, K2), the two layers (K1, K2) comprising an odd-numbered layer below the bent cap (B-1) and an even-numbered layer above said bent cap, the odd-numbered layer comprising or not comprising suspended monorail transportation, and the even-numbered layer comprising any of straddle-type transportation, magnetic levitation-type transportation, road transportation and railway transportation. The spatial transport system comprises two or more types of monorail transportation or a combination of one or more types of monorail transportation and other types of transportation, and solves the problems of intensive passenger flow, ground transportation congestion and low logistics efficiency.

A track-wheel based device is disclosed. The track-wheel based device may include a longitudinal member substantially perpendicular to an axis of motion of the track-wheel based device. The track-wheel based device may further include a first lateral member and a second lateral member, each being substantially parallel to the axis of motion of the track-wheel based device. The longitudinal member may be coupled to the first lateral member at a first location of the first lateral member and to the second lateral member at a first location of the second lateral member. The first lateral member and the second lateral member may be configured to undergo a relative angular rotation, in response to a planar misalignment of four or more points of contact between two or more guide tracks for the track-wheel based device and the track-wheel based device.

An overhead rail system includes a hollow tube having a channel running longitudinally along a bottom surface of the overhead rail. A stopper for use in the overhead rail, includes a base having a thickness less than a width of the channel of the overhead rail, a base length, a base width, and first and second countersunk threaded holes. The base further includes a pair of wings having a length greater than a width. The wings are rotatably attached to ends of the base and are rotatable approximately 90 degrees between a first position and a second position. Bolts may attach a stopper portion including a stopper base, and bumper base, and a bumper. The bolts further prevent rotation of the wings, thus securing the stopper in the overhead rail.

The present invention relates to the field of coal mine underground auxiliary transportation equipment, and particularly relates to an overhead monorail driving unit group realizing mechanical fast power distribution. The overhead monorail driving unit group realizing mechanical fast power distribution includes a rail, wherein the rail is connected with driving portions, carrying trolleys and a hoisting beam, the hoisting beam is disposed in a middle position of the driving portions and the carrying trolleys, and the driving portions, the carrying trolleys and the hoisting beam are connected through driving portion short pull rods, frame-shaped pull rods and driving portion long pull rods. Overhead monorail driving portions have four paths for transmitting a driving force to the hoisting beam, the frame-shaped pull rods directly transmit the driving force of the driving portions in positions far away from the hoisting beam to the hoisting beam, the objective is to reduce an accumulated peak value of the driving force of the driving portion in a mode of serial-parallel arrangement of the overhead monorail dtiving portions, the problem of horizontal direction bending failure of the rail caused by the driving portions in an operation process of an overhead monorail is solved, and the reliability and adaptability of overhead monorail transportation equipment are improved.
