Used cat 312d excavator manufacturer Japan original engine original pump Price instructions
A new cab design is adopted for 312d outside the cab. This design enables the fogs to be directly installed outside the cab with bolts before leaving the factory, or installed as an accessory later, so that the machine can meet the requirements of technical parameters and work site. The cab shell is installed on the frame with damping cab mounting seat, which can reduce the vibration and noise level and improve the comfort of the operator.
Machine safety system the optional machine safety system (MSS) uses programmable keys to prevent theft, vandalism and unauthorized use. MSS can use the electronic code key selected by the customer to limit the user or use time.

ACERT was used ™ Cat & reg; c4.2 engine with advanced technology optimizes performance and complies with US EPA Tier 3 and European IIIA emission regulations. By using advanced technology in air and fuel systems and integrated electronics, ACERT technology can reduce emissions during combustion. Caterpillar c4.2 engine can provide super power and generate higher hydraulic pressure to improve productivity and reduce the cost of handling per ton of materials.
The two-stage control device of engine automatic control and fuel delivery touch control can achieve the highest fuel efficiency and reduce the noise level. The fuel is delivered by ADEM ™ A4 engine controller management, so that every liter (gallon) of fuel to maximize efficiency. Flexible fuel distribution enables the engine to respond quickly to different application requirements.
The vibration and wear resistance of crankshaft are improved by induction hardening and forging. The compression deformation of heat-resistant aluminum alloy piston is small, which can improve efficiency and prolong service life.
The fuel saving mode is provided as a standard function, which not only takes into account your requirements for performance and fuel economy, but also achieves the digging power and lifting ability under the standard power mode.
