��What One Lifting Truck Will Do in Factory Hauling

A TRUCK which will lift all but the largest castings upon its back, and then carry its load away with but a single man to operate it, has been intro- duced into the factories. Its usefulness is almost unlimited.

Medium-sized machines in the foundry and shop can now be carried about, not with a ten thousand dollar traveling crane, but with a little eighty-five dollar hand truck. Small castings, such as the little heater shown in the photo- eranh noorl n-^ \ '

moved with rollers and crowbars, which require sev- eral workmen and precious time.

Each truck is provided with a hundred separate platforms. These are distributed about the shop.

��When a product has gone through one operation, it is loaded directly upon the platform, on which it is carried from one place to another.

The truck sides are parallelograms. When they are in their collapsed position, the truck is readily slid under the loaded platforms. Then using the truck handle as a lever, the workman attaches a hook upon the stub end of the handle and raises up the sides until they form an oblong. The sides are automatically locked in this position, and the raised load may be wheeled wherever desired. By pressing a pedal on the head of the ma- chine, the sides are tripped. The load is gently lowered by a hydraulic check.
