Item: QY70V Description: 1. Imbued with appearance model of artistry Pretty figure: Symmetrical or approximate symmetrical appearance model of the completed crane give us aesthetic feeling of harmoniousness Pretty line shape: Perfect combination of big arc and harden straight line, has the advantage of fineness, smoothness, nature etc. Pretty color: The completed crane has good color matching, which can dispel people's visual fatigue. 2. Excellent lifting capability: Compared with the same kind of product, lifting capability exceeds the domestic and international comprehensively, having reached a new height, especially the capability of mid-extended boom at large scope. The boom with big round angle hexagonal profile. Synchronous sequence telescoping system with double-cylinder together with clamping roller, is with high working efficiency. There is boom nose sheeve. 3. German, slewing reducer, main and the auxiliary winch reducer are made by rexroth, every kind of controlling valve, valve group are all imported. Hydraulic pipeline adoptsimported clamp-type pipe fittings. 4. Every mechanism is designed meticulously: Realize 1+1>2 Hoisting mechanism: The skillful automatic pressing annunciator avoid the possibility that glides twice. Derricking mechanism: The derricking cylinder is equipped excellent balance valve of Bucher, which make the derricking reliable and steady. Slewing mechanism: Ouble-controlling slewing loop, assure the slewing smooth and reliable. Accurate and reliable hydroelectric proportional of the electric liquid, make the action has good tiny vibration. Outrigger beam has secondary synchronous 5. Complete safety devices: Lifting height limiter Pendant type over-fall cut off device Automatic limit moment with the function of self check and annunciator. Outrigger boom cylinder with bidirectional hydraulic lock inside. In the hydraulic system, there are the safety devices like over-flow valve, safety valve and brake valve and so on. In order to avoid the accident due to the oil vessel broken because of the oiled road and over-load. 6. Long-term use value: Economy and long life-span. Energy saving and low oil losing For the routine parts which are easy to be damaged, we often adopt the common pieces, which are easy to get. In this way we may reduce the cost. Cy and high accuracy. ), which can remove the dust and impurity in the oil, both reduce the malfunction and abrasion and extend the life span of the hydraulic components. The well-designed hydraulic system (e. G. The filtrate device of high-efficien The first-class welding technology to ensure the structure well-knit for long time. 7. Friendly environment We adopt the low-harmful engine: Low oil losing, low noise and high efficient, and reduce the environment pollution greatly. Fewer soft vessels are used, instead, the imported clamp-type pipe fittings are adopted, which can prevent the oil from losing and reduce the environment pollution as much as possible.
