| The final drives were selected for heavy-duty work cycles and a high tractive effort. |
|
| The tractive effort of the machine seems weak, especially in this deep snow that we have now. |
|
| And because the tractor unit is self-contained in a single unit, greater tractive effort can be applied to help move the unit through wet soils. |
|
| Operators of road slugs in the Northwest are usually lines with poor track and steep grades which require a lot of tractive effort, but not necessarily more horsepower. |
|
| These tracks enable a machine to operate in conditions where low ground pressure and high tractive effort are needed while minimizing the damage to the operating surface. |
|
| Features include advanced hydraulic controls and impressive power in terms of rated operating capacities, tractive effort, bucket breakout force, and the like. |
|
| Without the slugs they would have to use five regular locomotives to get as much tractive effort, even though they only need three units worth of horsepower. |
|
| They point out some important differences between motor graders and other earthmoving machines when it comes to converting engine power to tractive effort and work output. |
|
| Passenger locomotives develop less starting tractive effort but are able to operate at the high speeds demanded by passenger schedules. |
|
| Not all boilers deliver full power at starting and also the tractive effort decreases as the rotating speed increases. |
|
| Therefore, the combination of starting tractive effort and maximum speed is greatly influenced by the diameter of the drivers. |
|
| These categories determine the locomotive's combination of physical size, starting tractive effort and maximum permitted speed. |
|
| They do not develop as much starting tractive effort as a freight unit but are able to haul heavier trains than a passenger engine. |
|
| British railway companies have been reluctant to disclose figures for drawbar horsepower and have usually relied on continuous tractive effort instead. |
|
| A variety of calculations and formulas were applied, but in general railways used dynamometer cars to measure tractive force at speed in actual road testing. |
|
| Tractive effort is a measure of the heaviest load a locomotive can start or haul at very low speed over the ruling grade in a given territory. |
|
| Tractive Effort is defined as the average force developed during one revolution of the driving wheels at the rail head. |
|
| Tractive force, as noted earlier, is largely determined by the boiler pressure, the cylinder proportions, and the size of the driving wheels. |
