LD type electric single-girder crane


LD type electric single-girder crane has a reasonable structure, the characteristics of the rigidity is strong.The machine used together with CD1, MD1 electric hoist, HC type, is a kind of small-sized lifting machinery.The weight of 1 t - 32 t.Span 7.5 22.5 m, the level of work for A3, A5, working environment temperature is 25-40 ℃.
This product is widely used in factories, warehouses, different occasions, such as lifting the goods yard, prohibited to use in the inflammable, explosive or corrosive medium environment. This product is equipped with the ground and control room two operating forms.Control room is open and closed two, can be divided into the left or the right to install according to actual condition in two forms, one door direction, which has two kinds of side and end, in order to meet user needs in the different cases.
