QTQX50 / QTQX80 Series

  • Good T/C self-adaption for severe road condition and mutational load.
  • With two forward shifts and two backward shift, the transmission has a better transmission capacity and more stable operation.
  • Added PTO(oil pump) output, the transmission can be adapted to more engines.
  • With two valves integrated, the transmission has a tight structure and easy to assemble and disassembly.
  • Equipped with energy storage buffer- control system and with the optimized control valve, the transmission is more easy to operate.
