COAL and ASHES CONVEYORS

of the correct type are the most efficient and economical means of handling and storing at the Power Plant.

THE PECK Overlapping Pivoted Bucket

CARRIER is the most popular of the Pivoted Bucket Conveyors. Successful installations are numbered in the hundreds the total length in use would exceed 20 miles in length. Handles coal and ashes at lower cost per ton than any other type of conveyor. Pock Carrier Book No. 120 not only shows the construction and actual photographic installations, but gives the reasons for its superiority over all other types.

Sent upon request.
