在60年代,单梁起重机在国外得到了广泛的应用。它的自重轻,厂房结构的负荷小,可以采用轻型的大车轨道梁。单梁起重机的建筑高度低,电动葫芦可以更加接近轨道梁,厂房的空间可以更好的利用。它的有效载荷和自重的比值较大,使耗电量相对减少。单梁起重机的结构简单,因而安装快,维护方便,价格低廉,交货期短。它的操作简便,不必配备固定的司机,使用时很经济,所以国外的单梁起重机绝大部份是地面操纵的,带司机室的必须特殊定货。
In the 1960s, single-girder cranes were widely used abroad. It’s light weight, plant structure of the load is small, you can use the light cart rail beam. The single girder crane has a low building height and the electric hoist can be closer to the rail beam and the plant space can be better utilized. Its payload and self-weight ratio is larger, so that the relative reduction in power consumption. Single-girder crane structure is simple, so fast installation, easy maintenance, low prices, short delivery time. It is easy to operate, do not have to be equipped with a fixed driver, it is economical to use, so the vast majority of foreign single-girder cranes are ground-based, with the driver’s room must be special orders.
