Advantage introduction
    • Fixed mast support. Equipment can be transferred easily and quickly.

    • Rotary drive with three motors, which ensures large torque, high reserve coefficient and stronger construction capacity.

    • High construction efficiency thanks to big flow main pump, multi-gear rotary drive.

    • More stable structure and stronger bearing capacity thanks 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 controlpanel.360 full view monitoring.

    • Options: Auto-lubrication, spin-off.
