• Zoomlion's specific-use in-house telescopic-crawler undercarriage is used to achieve superior stability, transport convenience and travel performance.
• The main winch uses the single-layer-rope drum, winch extends service life of the main winch rope significantly;
• The world advanced load-sensing, proportionally-controlled hydraulic systems are used to achieve high efficiency and less energy loss.
• World-class components are used to achieve excellent performance,
• Optimized large-triangle luffing mechanism with high supporting positions decreases mast deformations and increases the borehole accuracy.
• The rear-mounted stabilizer can ensure stability of the machine and verticality of the borehole when imposed by great crowd force.
