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,

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.
The
gradeability of hybrid harvester at full load was shown in Figure 3.
