Product Description

Company Information 

Shandong Mingwei Hoisting Equipment Co.Ltd. started manufacturing tower cranes from the very year our firm founded in 1994. And now can offer tower cranes with a maximum lifting load form 2.5t to 20t, which is from QTG25, QTZ25, QTZ31.5, QTZ40, QTZ63, QTZ80, QTZ100, QTZ125, QTZ160 and QTZ260, luffing tower crane, topless tower crane and so on to meet the demand of various kinds of customers in different construction works.
With climbing cage, our crane can change the height itself by adding and reducing its standard sections.
And the same tower crane can have different lengths of jib with different quantities of jib sections. We will offer the drawing of the same when the goods are delivered.
