A short chain to attach tubs to an overrope in endless rope haulage by wrapping it around the rope. The chain may be about 12 ft (3.7 m) long, of low manganese steel, with 3/8- in-diameter (9.5-mm-diameter) standard links. At one end of the chain, a ring 4 in (10.2 mm) in diameter is attached to the drawbar hook of the tub, and to a hook about 3/8 in in diameter to secure it to the rope at the lashing end. On an undulating road, two lashing chains may be necessary--one forward and one rear of the tub.
