Abstract: A connection system arranged for connecting a first monorail beam to a second monorail beam includes upper connection means and lower connection means. The lower connection means is configured to support the second beam from below and the upper connection means is configured to be connected by movement of the second monorail beam downwards relative to the first monorail beam, wherein the upper connector limits longitudinal relative movement between the first monorail beam and the second monorail beam when connected.

Abstract: A connection device for suspending a monorail beam includes a top anchor integrated with or attachable to a roof bolt and a clamping device for connection to the monorail beam. The clamping device has a housing attachable to the monorail beam. The housing includes a central recess with an opening configured such that the top anchor is movable into and out of the central recess along a first axis through the opening. The clamping device has a plurality of locking members radially movable into and out of the central recess with respect to the first axis between an inner locking position in which the locking members prevent the top anchor from moving out of the central recess, and an outer open position in which the top anchor is free to move past the locking members, each respective locking member being provided in a respective radial guide recess of the housing.

Abstract: A transport unit, a material transfer structure and a material transfer unit for a mobile haulage arrangement are arranged for continuously conveying fragmented material in a conveying direction. A mobile haulage arrangement and a method for continuously conveying fragmented material in a conveying direction is also disclosed. The transport unit includes two ground transportation structures and a support frame suitable for fitting a belt of an enclosed belt conveyor thereunder. The ground transportation structures has at least one height adjustment device, wherein the support frame comprises at least one connector, which is arranged for connecting a support structure thereto. The height adjustment devices are arranged to vary the position of at least a portion of the support frame in relation to the ground transportation structures.

Abstract: The disclosure relates to a support structure for supporting a belt of an enclosed belt conveyor between two transport units and a corresponding method. The support structure between two transport units includes a first end element having a main extension in a longitudinal direction, a width extension in a width direction orthogonal to the longitudinal direction, and a height extension in a height direction orthogonal to the longitudinal and the width direction. At least one guide assembly is arranged to engage opposite longitudinal edges of the belt. A first telescopic element is connected to the first end element, wherein an outer end of the first end element has a first end connector arranged to form a connection with a first transport unit.

Abstract: The disclosure relates to a drive arrangement for driving a belt of an enclosed belt conveyor. The disclosure further relates to a mobile haulage arrangement for continuously conveying fragmented material in a conveying direction and to a method for driving a mobile haulage arrangement. The drive arrangement for driving a belt of an enclosed belt conveyor include a conveyor drive assembly arranged to drive the belt of the conveyor run in the conveying direction, and a return drive assembly arranged to drive the belt of the return run in an opposite direction.
