Features of ZOOMLION QAY800 all terrain crane
QAY800 all terrain crane is a key product of the company. It is a high performance product model with high efficiency, reliability, practicability and close to the market.
Close to the market, widely adapted
Different light and heavy arm of the unique combination of QAY800 all terrain crane to achieve a wide range of market adaptability, can various conditions in the petroleum chemical industry, iron and steel, municipal construction and other industries and below 2.0-2.5MW wind power system application system of excellence each one takes what he needs, to achieve the customer operation efficiency and high value in return.
Moreover, QAY800 has the obvious characteristics of wind power installation, the chassis through a special design, with more accurate minimum ground clearance and greater climbing ability, with the wind micro special electric luffing boom, the wind power installation is more convenient, the wind power lifting lifting capacity is more than 1000 tons of the industry the crane, the 2.0MW fan hoisting the typical working conditions of transportation cost saving 20% than the regular models.
Independent innovation technology leading
QAY800 all terrain crane adopts National IV engine, 8 axle chassis, all wheel steering, has the world's longest 91m7 telescopic main arm, maximum lifting torque 2500t.m, maximum lifting height 145m.
QAY800 integrates 72 independent techniques, such as: to enhance the operation efficiency and safety of rotary, truly realize the "light heavy slow, nearly far slower" rotary patented technology; efficient and convenient manual crane split technology; energy saving, stable and closed hydraulic volumetric speed control technology and load sensing technology, security technology low frequency and comfortable oil air suspension independent telescopic steering; "one key" and "adaptive control technology of ultra rope control technology"; "N" type legs and safety load protection technology and a number of key technologies. Among them, nearly 50 patents have been declared, and nearly 30 items have been authorized.
Products reliable, intelligent and environmental protection
QAY800 all terrain crane listed after the product testing, strict security, the expansion bolt mechanism through thousands of expansion test without failure, super institutions experienced 5000 fixed rope length and arm length with no fault, fan hoisting special conditions experienced repeated 1000 times the suspended load working condition of stable structure, amplitude stability without fault. In addition, the product passed the reliability test stipulated by the national acceptance standard, and the main engine passed the 15000km road test without fault, and verified by the wind power field hoisting on the bad site of the wind field.
With the global positioning system QAY800 all terrain crane, remote equipment monitoring and fault diagnosis; steering servo control system with speed and steering automatic locking safety device for car safety; system with torque limiter, rotary speed automatically, cutting force limiting safety monitoring device and automatic mode, low emission and low noise. Its fan lifting condition transport vehicles only 8 trolley, less than the same industry operating conditions 2 cars, saving costs for customers. Water cooling system is used, which can save more than 4% energy when the engine is running.
