2013年8月30日,由宁波北仑国际集装箱码头有限公司研制的龙门吊无电缆集装箱吊具通过了宁波市交通委员会的验收。目前,港口使用的龙门吊吊具大多采用电缆送电控制,存在诸多弊端。由于使用环境恶劣,电缆长期受风吹、日晒、雨淋、油污浸泡、紫外线辐射等侵害,电缆线很容易损坏。在使用过程中,进常发生电缆出框,电缆被吊具、钢丝绳滑轮压断的事故。而更换一根电缆线,至少需要花费4万元。为了提高生产效益,进一步节能减排,
On August 30, 2013, the gantry crane without cable container spreader developed by Ningbo Beilun International Container Terminal Co., Ltd. passed the acceptance of Ningbo Traffic Commission. Currently, most of the gantry cranes used in the port use cable transmission control, which has many drawbacks. Due to the harsh environment, the cable long-term wind, sun, rain, oil soaking, UV radiation and other violations, the cable is very easy to damage. In the course of use, often into the cable out of the box, the cable was spreader, rope pulley pressure off the accident. The replacement of a cable, at least spend 40,000 yuan. In order to improve production efficiency, further energy-saving emission reduction,
