Transport unit, material transfer structure, material transfer unit, and mobile haulage arrangement method

A material transfer structure for a mobile haulage arrangement arranged to continuously convey fragmented material in a conveying direction, the material transfer structure comprising:

• a base frame with a first and second end;
• a plurality of guide assemblies arranged to engage opposite longitudinal edges of a belt of an enclosed belt conveyor;
• and
• a rolling device arranged to turn the belt between a conveyor run and a return run arranged at the second end of the base frame, wherein the plurality of guide assemblies is arranged on the base frame for opening and/or closing the conveyor run and/or the return run of the belt between the first end and the second end of the base frame, the conveyor run and the return run being positioned substantially at a same level at the first end of the base frame, wherein the base frame includes two parts arranged to allow for relative translational movement in the conveying direction between them, the rolling device being arranged at one of the two parts of the base frame.

A material transfer unit for a mobile haulage arrangement arranged to continuously convey fragmented material in a conveying direction, the material transfer unit comprising:

• a transport unit including two ground transportation structures arranged for movement along the conveying direction, a support frame connecting the two ground transportation structures and suitable for fitting a belt of an enclosed belt conveyor thereunder, and each of the two ground transportation structures having at least one height adjustment device, wherein the support frame includes at least one connector connecting a support structure thereto, wherein each of the height adjustment devices is arranged to vary a position of at least a portion of the support frame in relation to one or both of the ground transportation structures;
• and
• a material transfer structure arranged at the transport unit, the material transfer structure including a base frame having a first and second end, a plurality of guide assemblies arranged to engage opposite longitudinal edges of a belt of an enclosed belt conveyor, and a rolling device arranged to turn the belt between a conveyor run and a return run arranged at the second end of the base frame, wherein the plurality of guide assemblies is arranged on the base frame for opening and/or closing the conveyor run and/or the return run of the belt between the first end and the second end of the base frame, the conveyor run and the return run being positioned substantially at a same level at the first end of the base frame.
