主要技术性能与同行先进水平的比较Compared with the interline product

1.方圆牌塔式起重机各项性能参数均达到国内水平。QTZ63（TC5510）塔机额定起重力矩630kN.m，最大起重力矩870KN.m，最大起重量为6t，最大工作幅度为55m，起升速度最高可达80m/min。Fangyuan brand tower crane various performance parameter reached the leading domestic level. QTZ63 (TC5510) rated lifting torque 630kN oxided j m, maximum lifting torque 870KN. M, maximum lifting weight, the maximum working range for the author 55m, hoisting speed for maximum is 80m/min.

2.在目前中国起重机生产企业遍地开花的状况下，工艺生产能力仍可以代表着产品的优劣，方圆集团在几十年的生产过程中积累了丰富成熟的生产工艺：标准节的四肢同铣保证塔身标准节制做的垂直度和上下两个平面的平行度，从而保证了整个塔机安装后的垂直度；起重臂的接头均设计为锻打件，锻后加工的接头不但接头本身的机械性能有所提高，而且起重臂之间的配合间隙小，保证起重臂的连接刚度，使塔机回转更为平稳；所有大的关键部件均有专用工装和专用设备制造，焊接后抛丸处理，增加了表面强度，消除了内应力。

In China crane production enterprise blossom everywhere condition, craft production capacity can still represents the product quality, fangyuan group in decades of production process accumulated the rich mature production process: standard section milling guarantee with the limbs of standard temperance do campanile verticality and upper and lower two planar parallel degree, so as to ensure the whole oxided verticality after installation; Hoist boom joints are designed for forging parts, after the joint forging process of mechanical performance not only connector itself, and improve the coordination of hoist boom small clearances, guarantee the hoist boom, joint stiffness oxided more smoothly; turn All the big key parts are a special tooling and specialized equipment manufacture, after soldering peen-forming processing, increases the surface strength, eliminates stress.
