Rotary drive with three motors, which ensures large torque, high reserve coefficient and stronger construction capacity.
High construction efficiency due to big flow main pump, multi-gear rotary drive, and two-speed crowd cylinder.
More stable structure and stronger bearing capacity due to large supporting angle of the mast cylinder, lower center of gravity, and reinforced chassis.
New generation cab with better vision, more comfortable operation, new electrical control panel. 360 degree full view monitoring.
Options:5th generation rotary drive, auto-lubrication, spin-off.
