Other significant upgrades done include a higher gradeability
of 45.2 percent, as well as increased resume-accelerate (R/A) gear ratio of 4.88 from 4.33.
Among these machines, Sany's first hydraulic wheel excavator SY155W is under the spotlight of the construction industry for its brand-new hydraulic traveling transmission system, gradeability
and off-road performance.
Three categories of peak and continuous power performance simulation tests are applied to the EV system-level model (as exemplified in Figure 3: the maximum speed, acceleration time and gradeability
The difference in powertrain also affects gradeability
, with the Ather 340 rated at 15 degrees and the Ather 450 capable of scaling 18-degree inclines.
The electric bus weighs 12 tons, is equipped with a 30% gradeability
, can reach 120 km/h maximum speed, and has a 400 km (250 mi) overall range.
By marrying the haul truck speed rimpull gradeability
model with the real-time performance data coming off that truck, this can be overlain with high-accuracy survey profile data from the as-built road to determine the variation in grade of the road every few meters.
A study by the North Atlantic Treaty Organisation's Research and Technology Organisation found that: "The automotive performance of hybrid electric vehicles in terms of speed, acceleration, gradeability
and stealthy operations is superior to the performance of mechanically driven vehicles ...
As part of its rough-terrain capabilities, the Genie Z-60/37 FE offers 45% gradeability
, 33cm of ground clearance, and is capable of travelling 25% faster than other typical diesel-powered units.
However, if Naturally Aspirated (NA), the acceleration and gradeability
of the vehicle are limited by the downsized displacement.
is defined as the highest grade a vehicle can ascend maintaining a particular speed.
When constructing a series of technology packages which substitute various engines and transmissions it is important to assure that there is reasonable gradeability
and drivability across simulations.
of hybrid harvester at full load was shown in Figure 3.
