QAY300 All Terrain Crane is adoption of 7-axle all terrain crane chassis, with variable rate hydro-pneumatic suspension and high ride ability, it is comfort and safe to drive. Oval section of base boom, single-cylinder Self-Shortening section, powerful lift ability. It is safety and reliable, depends on the use of computer integration control technology and Fieldbus. And also with the intelligentize fault diagnosis and operate automation. With the proficient use of Power points limit load, the crane is more energy-saving, low noise, environmental protection. The ultra-lifting equipment can further enhance the lifting ability, and the extent-alterable jib increases the scope of work. The towline device makes the installation of drop hanger easily, self-bucking counterweight hook device makes it more safety
