THE MECHANICAL HANDLING OF MATERIAL
The First Grain Warehouse, Manchester Docks.—The general arrange-
ment of this important warehouse is shown in Figs. 996 and 997, one being a geneial
plan and the other a perspective view. This granary, which is 448 ft. long by 80 ft.
wide, was erected in 1898, the whole of the superstructures being built of wood on the
American system with an external casing of brickwork and tiles.
The building has a storage capacity of 40,000 tons of grain. Theie are 226 bins,
varying in capacity from 37 to 300 tons each.
The granary stands at a distance of about 340 ft. from the side of the dock, where
the tower and ship elevator are situated, being connected with the main building by a
gantry with band conveyor. T he elevator is capable of raising some 350 tons of grain
per hour from the hold of a vessel containing a full cargo of grain. Arrangements are

made in the tower by means of which the grain is weighed whilst being conveyed from
vessel to elevator, the weight being there checked by both the representatives of the
vessel and the owner of the grain. After the grain has been conveyed into the main
building, it is again lifted to the top of the central tower of that building, and thence
distributed to the various bins.
Appliances for the delivery of grain upon an extensive scale into railway trucks,
road vans and lorries, barges and coasting vessels (either in bags or in bulk), have been
provided, and can be worked concurrently.
In addition to the ordinary method of discharging grain by means of ship elevators,
one of Duckham’s pneumatic elevators has been provided, which is employed inter aha
for dealing with small parcels of grain, and with grain stored in positions which cannot
be reached by the ordinary ship elevator.
Power is supplied for the working of the elevator and the various band conveyors
in the main building, as well as leading thereto and therefrom, by two sets of horizontal
