我厂在制造箱形梁过程中,要经常把梁翻转,并需要在一定高度上起吊或卸下箱形梁。为了提高工作效率,降低劳动强度,我们在多年实践的基础上研制了一种由连杆操纵的箱形梁吊具。它结构简单,动作灵活,只需一个人操纵就能进行梁的翻转和吊运,对生产与装配非常适用。 I plant in the manufacture of box beam process, the beam should be turned over often, and the need to lift or remove the box beam at a certain height. In order to improve work efficiency and reduce labor intensity, we have developed a box-type beam spreader manipulated by the connecting rod on the basis of years of practice. It is simple in structure and flexible in operation, which can be used for turning and lifting of beams by one person and is very suitable for production and assembly.
