A promotional brochure from 1960 shows one of the assembly bays at Dorr-Oliver-Long.

Postcard Memories is a weekly series of historic postcard views and photos submitted by Marcel Rousseau.

Some were previously published by the Orillia Museum of Art and History and in the book Postcard Memories Orillia.

This picture from a 1960 promotional brochure published by Dorr-Oliver-Long is testimony to Orillia’s diverse industrial past.  

Shown is one of the assembly bays where hundreds of varied mechanical and structural jobs passed through during the course of a year. These ranged from 20-ton mine cars, 65-ton car tipples, 20-foot diameter filters, 15-ton, 60-foot mine skips to a variety of smaller equipment of every shape and description.  

Each bay was serviced by two 10- and 20-ton, single- and double-hook, travelling cranes with a floor clearance of 28’6”.

Shown are several “Granby” mining cars being tested and readied for delivery. These heavy-duty cars weighed close to two tons and would tip into a dumping position to remove the ore as seen in the second car from the left.

Dorr-Oliver-Long was one of the leading suppliers of a variety of mining equipment to the North American mining industry for many years.
