In operation a train of empties is pushed out to the loader andbacked through it until the last car comes in proper position,under the boom, for loading. As other empty cars are requireda cable connected to a drum is run through the machine and isattached to the draw bar of the first empty car. This caris then hauled through the loader, pushing the loaded car forward. Fig. 95. — A McGififert Log Loader. until the succeeding empty one is in position for loading. The-work proceeds in this manner until the skidway has been emptied. The Decker can travel under its own power from one point toanother, and can switch cars if necessary, although the latter isnot economical if a locomotive is available. It is recommendedfor narrow-gauge steel and wooden railroads. The Deckerloader costs from $4500 to $6000. (/) McGiffert. — This loader is similar in operation to theDecker. It has one elevated deck which carries the workingparts and when the machine is loading the frame is supported onfour corner posts or spuds which are curved in toward the 328 LOGGING lower extremities. Each post ends in a broad shoe which rests onthe crossties outside of the rail. The empty cars pass under thedeck, traveling on the main track. The loader is equipped witha pair of trucks at both the forward
