Coal Wagon Hoist, Adjoining Railway Approach And Control Boxes

MATERIALS: Steel with wooden platforms. The viaduct is of brick with sandstone dressings, while cabins are of timber.

PLAN: The hoist sits on the western edge of Railway Dock and is rectangular plan, with the viaduct approaching from the west.

EXTERIOR: The hoist comprises a five-storey tower with a central well of riveted lattice construction with a flat roof. There are staircases with wooden landings to each stage. The tower is supported to the west by angled girder buttresses. The hydraulic wagon lifting mechanisms are housed in casings on the north and south sides.

The bottom stage, with C20 concrete underpinning, has timber decking and a riveted sheet iron covered walkway. The approach ramp and wagon platform with hinged coal chute is sited to the second stage. There is a wooden control cabin to the top stage, and a series of cable pulleys on the roof. The ramp has a modern masonry buttress to the west.

The surviving section of the viaduct incorporates one segmental arch, with double wooden doors to the south. Adjacent to the hoist, on the south side of the viaduct, there is a single-storey timber cabin with tongue and groove boarded walls and a hipped slate roof. The door is of wood plank; windows are multi-paned with one casement and a pair of sliding sash windows.

INTERIOR: Cabins not inspected.
