Peter Mortensen Collection BCFP Renfrew Div. #73 a Model 6 Northwest Log Loader , #204 HDX Hayes Logging Truck . The #73 was originally a grade shovel that was used to build railroad grade and logging roads . About the same time "Cats" were being perfected and used to build roads , Log loaders were being developed to load logs . Grade Shovels were recycled to use as log loaders . In the picture a "Goose Neck Boom" has replaced the shovel boom and dipper stick and a single line is use for a "Tong Line". A couple of years later the operators cab would be raised , the boom would be set up to use three lines to control a "Grapple" . This machine may have been built in the late 1930's or 1940's and was still loading logs in the late 1970's . It's sad to think that after paying its own way for so many years , it was probably cut up for scrap !
