TL Electric Crawler Excavator

  • Zero emission, zero pollution, low noise.
  • Low use cost. The electricity consumption cost of pure electric construction machinery is about 30% of the fuel cost of traditional construction machinery.
  • Low maintenance cost. No need for regular maintenance for the diesel engine, such as replacing the engine oil and three filters, etc.
  • High battery safety, no risk of spontaneous combustion / deflagration.
  • The lifespan of the battery is more than 8-year. The recycle lifespan of lithium iron phosphate battery under 1C is more than 4000 times.
  • Optimized energy management, excellent energy utilization efficiency and endurance, together with high-volume lithium iron phosphate battery, 7 to 9 working hours after full-charging can be guaranteed with large capacity lithium battery.
