Abstract
A transport mechanism ( ) for transporting a load-assembly ( ), the transport mechanism comprising a closed flexible track ( ) supported at an internal side thereof by at least two support rollers ( ), which at a first position one of the support rollers ( ) exerts a force having a downward component onto the flexible track ( ) at a point of contact thereof with a ground surface and biasing arrangement for biasing said flexible track ( ) so as to assume a substantially circular shape. A displacing mechanism ( ) is coupled to at least one of the support rollers for mutually displacing the support rollers into a second position, against the biasing arrangement in which the support rollers force the track to assume a state in which an extended portion ( ) thereof is in contact with the ground surface and at least two of the support rollers are positioned at two ends of the portion.
