As a model based on XCMG-patented AC variable frequency traction system, XDA60E has its load capacity up to 55 tons, able to realize continuously variable transmission (CVT) and smooth power output. The six wheels can be independently controlled to achieve flexible transformation of the drive mode. The complete vehicle is equipped with a high-power braking resistance grid able to provide electric braking at any speed and thus prolong the service life of the mechanical brake parts. Its electric drive system has simplified the traditional mechanical transmission parts and thus reduced the incidence of failures. The maintenance cycle is24000 hours on average for its main electronic control parts, able to work together with the onboard centralized lubrication system to reduce the service and maintenance time and have the maintenance cost reduced by 30%. The ergonomic cab can offer sufficient driving experience and excellent operating comfortableness.
