• Leading performance: the boom length in full extension is 39.5m, the performance leading in 5%. The grade ability is 40%, which make the machine have good road adaptability.
• The unique U boom and plug-in boom head make the load-carrying capacity more balanced, and lift more smoothly.
• The unique stretch and retract technique prevents the misoperation; the stretch and retract of the boom is safer and more reliable.
• The control system is optimized by 8 patents; lifting, rotation, and luffing are easy and reliable.
• Six unique technologies supply the quality assurance, and make the products keep a high value.
• The innovative jib system adopts embedded block, plug-in boom head and octagon jib, which has excellent lifting performance and safe and reliable lifting work.
• The unique stretch and retract technique avoids the bend of the core pipe and cylinder and the break of the boom caused by misoperation, improving the safety of the operations.
• Eight patent techniques ensure the smooth, high efficiency and energy conservation of the lifting, rotation, and luffing systems.
• Adopt the new hydraulic motor with big torque starting point, making the secondary lifting safer.
• The torque limiter adopts colorful LCD display, realizing the 1ff8 intelligence of the failure diagnosis. The precision is ahead of the industry.
• The humanity design makes the cab and control cab more spacious, and easy to operate.
• Six unique manufacturing technologies ensure the high quality.
