With the continuous improvement of China's industrial equipment level, as the key material lifting equipment within the industrial plant, the overhead crane and gantry crane, the safe, reliable, maintenance-free Advanced increasingly been widespread concern. Moreover, China's crane industry is relatively advanced technology, there is a big gap, innovation has become China's crane industry to revitalize national industry can not be ignored. As China's emerging professional crane factory, after just two years of international cooperation, open up a small size, light weight, energy saving, environmental protection, world leader in the innovation of road crane, crane technology has become one of China's leader . Crane smooth, reliable, good operability is the common aspiration of all users. Crane and trolley carts institutions have adopted variable frequency variable speed system, a good anti-sway feature allows the crane up and running, the brake is implemented in a smooth control. Degree swing hook is minimized, conventional cranes inertia braking impact resistance and other unstable factors have been effectively avoided. Good CVT system allows horizontal displacement of the hook to reach even the naked eye can not detect subtle level, especially in precision parts assembly plant, handling situations valuables or important piece flipping section, innovative crane lifting all become Stability protection. Hardened gear processing technology has matured, has been widely used in the world. High strength, small size, low noise, maintenance-free gear unit are hardened through Austrian crane and an innovative key technologies. Most of the conventional crane soft tooth surface reducer, bulky, short life, the high failure rate of soft tooth surface reducer crane has become the bottleneck of industrial development, is brewing in the country crane new standards in the drafting process has been the subject To eliminate soft tooth surface reducer, Hardened reducer crane structure optimization, reducing the weight of the crane, lifting mechanism to make more compact, higher transmission efficiency. Crane hoisting mechanism, cart driving mechanism, trolley driving mechanism are made of hardened reducer, a new starting point for reshaping industrial crane. Slowdown and phase sequence having a limit of four point limit programmable from the ceiling hook position is the fundamental guarantee for the rise and fall, which is the crane's innovative masterpiece. Users of hook hoisting, heavy fall of worry of the past. Rope is a key component of the crane, the better the smaller the diameter bend, the longer the life rope. Crane hoisting mechanism through a variety of experiments, the optimized shaped wire, high-strength, galvanized steel wire rope, wire rope strength of 2160N / mm2, higher than the strength of conventional products more than 50%, more than 1/3 of the diameter of fine wire rope life than Conventional extended from 3 to 5 years, and added galvanized anti-rust function, no need for regular anti-rust oil coating. Innovative Austrian crane rope through truly safe, long life, maintenance-free. Crane as special equipment for its national security and reliability very seriously. Crane safety brakes are the key to security. Conventional brake shoe type hydraulic pusher bulky, braking accuracy, heavy maintenance, easily lead to accidents. Crane using advanced electromagnetic disc brake, which lifting body uses brakes with brake clearance automatic compensation function, so lifting the braking torque remain constant, eliminating the slip hooks and other hazards, but also eliminates a lot of maintenance work . Conventional brake friction plates containing asbestos dust generated during braking, larger environmental pollution. A new generation of brake sealed structure, asbestos-free brake pads, brake dust is not generated, a truly environmentally friendly products. Cranes for innovation makes the new generation of crane brakes safer and more reliable. The innovative crane is multifaceted, from the selection of high-strength bolts, development slippery electric systems, improving the track selection, the process of innovation, welding method change, coating technology improvement, etc., all reflect the innovation of subtle and rigorous. Crane innovative start from international cooperation, based on improving the localization rate to achieve the international advanced level of domestic crane as the goal. As a new army crane industry, crane its excellent quality and leading-edge technology, only 1 to August 2007 had sales of a variety of dual-beam bridge crane, single girder overhead cranes, gantry cranes, semi-gantry cranes, jib cranes and other more than 200 sets, both in the field of machinery manufacturing, automobile, steel, aviation, aerospace, military, or oil, electricity, paper, chemicals, nonferrous metals, etc., have successful track record, and is gradually becoming China industrial crane replacement. Crane not a long history, not the shoulders of giants, but by virtue of geography, personnel and market advantages Beijing, to take independent and cooperation of both the road of development, the introduction and assimilation of advanced technology, in close connection with market-oriented, clear direction so that every step of innovation to achieve efficiency and perfect.
