ELWELL-PARKER GIVES YOU EXTRA When you look beneath the steel plates— inside the housings of an Elwell-Parker Electric Truck, you see many reasons why it delivers extra power to the pay-load. In the two motors, one to drive and one to lift, you notice extra heavy copper coils. Unusually large armatures. Forged field rings. The drive motor carries eight brushes. Power failure at crucial moments is impossible because there are no fuses anywhere on an Elwell-Parker. The motors are sufficiently heavy in copper to absorb all the power FOR YOUR DOLLAR that can be delivered to them. On occasion, this may be five times normal demands. Accurate machining contributes to the high efficiency of the truck. Some parts of the motors are held to within .0003 of an inch. So are the wheel bearings and differential cage bearings. Without exception, all shafts turn on ball or roller bear- ings. And every one is either grease packed or pressure lubricated. Some idea of the tremendous pow- er generated and transmitted to the Write for this New Booklet. Tremendous savings are being made by handling ma- terials on skids with Elwell-Parker Electric Trucks. The advantages, types of materials handled, and methods used are pictured and explained in a new booklet, “Handling and Shipping on Skids.” It will be sent without charge or obligation to interested ex- ecutives. Write The Elwell-Parker Electric Company, 4200 St. Clair Avenue, Cleveland. ELWELL- PARKER DESIGNERS AND BUILDERS OF ELECTRIC INDUSTRIAL TRUCKS, TRACTORS AND CRANES FOR OVER A QUARTER CENTURY MARINE REvVIEw—March, 1931 wheels may be gained from the fact that drive axles must be built to with- stand atorque of 150,000 pound inches. From these facts, it is easy to see why the Elwell-Parker carries bigger loads, climbs steeper ramps and gives you more power for the dollar you invest in electric trucks. Motors are designed and built by Elwell- Parker solely for use in Elwell-Parker Elec- tric Trucks. Operating characteristics can thus be completely controlled to meet the enormous power demands of electrictrucking. 53
