我公司引进的1台LC31.5-740型运架一体式箱梁架桥机,具有提梁、运梁和架梁等多种功能,可承载900 t。由于相关技术资料有限,使得该机的很多故障特别是电控系统故障无法自行处理,耗费了大量的时间和资金。同时,其电控系统还存在控制线路繁杂、故障率高、维护成本高以及操作繁琐等缺点。为此,我们决定对该机电控系统进行改进。 I introduced a company LC31.5-740-type one-box-girder erecting machine with beam, beam and beam and other functions, can carry 900 t. Due to the limited technical data, many failures of the aircraft, especially electronic control system failure can not be handled by their own, consuming a lot of time and money. At the same time, the electronic control system also has some shortcomings such as complicated control circuit, high failure rate, high maintenance cost and complicated operation. To this end, we decided to improve the machine control system.
