50 PROPER SPEEDS FOR MOTOR TRUCK Ivan de Jongh Gives Valu able Figures for Power . Wagon Owners G. M. C. Official Tells How to Keep Down Operat ing Expenses Ivan L. de Jongh, general manager of the Pioneer Motor Truck? corpora tion, distributers for G. M. C. trucks on the coast, has the following to say with regard to speeds: ■ "The subject of speeds of the proper type for the different size motor trucks , is a question that is very interesting to the truck world, and has been the subject of much discussion pro and con. Of course, the proper speeds are ' governed by several features, which may vary—the construction and? bal • ance of the .truck, the flexibility of its design, the roads over which it runs and the type of load that it carries. ? • "But going upon the assumption that the - trucks and roads and conditions •re normal, the following speeds seem to be the popular ones: Approximately • 20 to 25 miles for. the 1,000 pound | truck; 16 miles for; the one ton; 14 to 15 for the two ton .truck; 12 to 13 for the three ton. and 10 to 11 miles for the Aye ton. •-'-?, - "The manufacturers are fairly uni -8 versal on this point. This does not mean, of course, that a man should run his truck anywhere 7 near ?'the limits of these speeds at all times; but means that he should be enabled,?wben a good piece of road presents itself, to drive his. truck over same at the ; top , speed without racking : it, and cutting down the time, thereby increasing his earning capacity. « "There is absolutely no economy In ■ the motor truck save the -two features • of speed and endurance over? horses. . Any wagon can be loaded as quickly or unloaded as quickly as any truck, j Any team of horses can operate iup I to the capacity of 15 to 16 miles at j the same speed if it were possible | cheaper, than a truck. In other words, | to drive a team 16 miles in a day with I a three ton load and to drive a truck j over the same distance at the ';._ same j speed, the cost of the horses -would be | almost half of that of the "truck. Therefore, a saving of time must be f made between the point of loading and j unloading and the speed must be suf- j ficient to give the truck a daily mile age, if possible, equal to three teams, sor 45 miles. Whenever this Is accom plished there Is no. doubt ofj the econ omy. Of course, on long runs, where no stops are required and where? the same load is carried for the entire dis tance, a greater mileage could be ob tained with less Injury to the truck than the same mileage J would cost If stopping, starting, loading and/ un loading were necessary. '-! - - "-•.:'■"■■' "The objects in the speeds "of a truck Is to show an economy of sufficient substantiality to warrant the use of # the motor truck in place of the horse, and a happy medium Is the point aimed •at by the builders. If the builder or user is hoggish and, desires to. run his truck* at . an" excessive speed, then he soon destroys the life of it, due to road ':, shocks, vibration and chrystallisation, ! I thus robbing him, of the net earnings, ,and, on the other hand, often bringing about a condition where the builder and user are too conservative, j and. by low speed, rob. themselves of gross earnings sufficient to give them y the proper net earnings. Thus the speeds maintained by the standard builders of -£oday are for the purpose of regu lating this important? feature, 7 abso luetely essential to the welfare of the truck world." - -"?!??'?
