compared to reach the optimal combination, maximum limit satisfactory system function needs

Nevertheless, 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 electrics tacker 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.

Torque limiter on the mall was complicated varieties, the authors think that in the selection of the torque limiter, in addition to the alignment of the unit crane types of characteristics,
