Abstract: A transport vehicle for movement along the surface of the earth has a forward portion with apparatus mounted for mixing dry coal with fluid to form a slurry. The terminus of a cart-supported slurry hose apparatus is connected to the rear portion. A portion of the cart-supported slurry hose apparatus includes linkages which are attached to the rear portion of the transport vehicle. An improvement in the attaching apparatus includes means for pivotally attaching the terminus of the linkage to the vehicle. An arcuate support is attached to the vehicle over the rear end of the vehicle. A coupling is attached between the arcuate support and the linkage to permit the linkage to pivot freely while supporting the linkage from contact with the surface of the earth.
