Guide sheaves are mounted on each pair of girders, and over them pass chains connected to the platform and to the rams. The hoisting cylinders are placed inside the hollow uprights A, and the tipping cylinders are placed in the space between them. Each hoisting chain P is attached to the rear of the platform, and passes over a sheave M at the top of the staith, then under a guide sheave Q, then over one of the sheaves of the hoisting ram, then under a sheave on the tilting ram 0, then over a guide sheaves, then under a sheave on the other tilting ram, then over a sheave on the other hoisting ram the end being secured to the fixed point. The other chain has a similar course in the opposite direction. The other connected chains are attached to the front of the wagon, and each passes second over a guide sheave U over a sheave on the adjacent hoisting ram, increased under guide sheaves V to a sheave on the ram of the other hoisting cylinder, the end being secured to a fixed point, the course of a the two chains being similar, but in opposite directions.

A chain is connected to the bracket carrying the sheaves of the hoisting rams, and passes over a pulley at the top of the staith, and has a weight attached to it to counter balance the platform wagon and rams. The loaded wagon enters upon the platform at the upper part of the staith, and being heavier than the counterweights, the platform and wagon descend under the control of a suitable brake, the tipping being effected by arresting the required counter-weights.
