A conveying or transportation system having a haul rope (22) mounted for movement along a path, a terminal (31) positioned along the path and having a docking surface (52), and a carrier unit (27) coupled to the haul rope (22) by a rope coupling assembly (51), preferably in the form of a hydraulic piston-cylinder assembly (53), formed to create and maintain tension in the haul rope (22) during transport. The fluid piston-cylinder assembly (53) preferably includes two pistons (57, 58) which are movably mounted in a common cylinder (56) and connected to a fluid circuit (54) which allows fluid to flow from opposed sides (68, 71) of the respective pistons (57, 58) for floating of the pistons (57, 58) inside the cylinder (56) upon docking and over-driving of the haul rope (22).
