JCM907D Crawler Excavator

☆ It adopts originally imported Cummins B3.3 engine which features Tier 2 standards, energy saving, environmental care, and convenient service and maintenance;
☆ It adopts radial seal air filter with pre-filter which effectively prolongs engine life, with fuel filling pump as standard device.
☆ It adopts originally imported hydraulic parts, which features stable and reliable quality, high efficiency, and big digging force;
☆ It adopts new type cab and seats, and reinforced working device, which make it possible for 360°slewing within the radius of 3.7m, featuring good adaptability.
☆ The electric control system features real time monitoring, automatic self-diagnosis and recording, electric throttle, and 4 kinds of work modes.
☆ The dozer blade and breaker pipeline are available as standard devices for multiple operations like digging, landfill, breaking, and grading.
☆ The multifunctional GPS can achieve remote control and data transfer so that the real time machine conditions can be known
