QTZ series tower crane is a kind of upper-slewing fixed type tower crane. It can be used into every kind of industrial and civil construction, especially suitable for the construction site which is narrow and landform is complicated.
Tower crane has hoisting, slewing and trolleying mechanisms. They can work respectively or together to raise working efficiency. Hoisting mechanism adopts double-speed electromotor, it has two kinds of work speed: Lifting and slowly in position, so as to satisfy different work requirement. Jib can rotate 360° Freely. Level arm frame, trolley range-changing, agile and reliable, lifting in position is accurate. It can satisfy vertical and level transport demand of construction at a time.
