the three breaking mainstream enterprise

2005 to 2010, showed significant changes in micro-environment: Countries increase infrastructure investment, power and other major construction projects led to the Scissor lift process transformation, the end of this process, the three breaking mainstream enterprise: First, the world of speed, the second is the crane product structure and category further subdivided spectrum spans from 5 tons to 2,000 tons cover, vehicle type, car type, all the earth, crawler, off-road tire, etc. to get commenced; Third, large-scale. China's largest tonnage of 200 tons crane before history was broken, from the end of the world Cranes hundred-ton to kiloton crossedNevertheless, the authors think that the torque limiter on the mall at that time there is still a lot to improve local. Specifically there are two aspects. First, the torque limiter to improve primary element such as sensors, photoelectric encoder and line plug-ins, mostly due to one component manufacturers outsourcing, outsourcing products, because since the product quality varies greatly, simply because some shortages affecting the entire system functions . Solution to the problem is the manufacturers of the primary elements carefully selection, repeated experiments, compared to reach the optimal combination, maximum limit satisfactory system function needs; Second, some manufacturers component sensing devices depict it has not done for a long time solid, such as the appearance of the flash when testing very precise, 2-3 months after rendering errors often lead to torque limiter which the whole system failure, affecting the system robustness.
