1. EX1200-7 Hydraulic Excavator
Hitachi Construction Machinery Co., Ltd. has launched the EX1200-7 mining excavator featuring a choice of engines for compliance with emission regulations in different jurisdictions as well as greater capacity than previous models and improvements in fuel economy, ease-of-use, maintenance, and comfort.
The main features are as follows.
- Better fuel economy
A larger bucket capacity that enables more work to be done, a larger oil cooler that allows for a slower fan speed, and optimization of hydraulic control
- Improved ease-of-use
Addition of a regeneration circuit for the bucket and optimization of the front flow control valve, and automatic shift down when steering the excavator
- Easier maintenance
Improved access to filters, elimination of the need to replace the radiator fan belt as a result of switching to hydraulic drive for the cooling fan, automated cleaning of the radiator and oil cooler cores by running the cooling fan in reverse, addition of a starter disconnect switch to prevent the engine starting by mistake during maintenance work to make maintenance of electronic components more efficient through greater use of electronic control, a larger oil pan that enables longer intervals between oil changes, and the addition of automatic greasing of the backhoe bucket
- Improved comfort
Addition of Aerial Angle (360-degree vision system) and roller screen, and use of same cab interior as ZAXIS-6 series
- Compliance with emission regulations in different jurisdictions
A choice is offered of either an engine that complies with US Environmental Protection Agency (EPA) tier 4 emission standards and European stage V non-road emission standards or a fuel-efficient engine for use in other jurisdictions.
