New Good quality Tower Crane (QTZ7030)
1. The main products of the QTZ series tower crane, engineering machinery, single/twin beam bridge crane. It was selected as "Designated Products for Construction of 2008 Olympic Games".

2. This tower crane's upper part adopts the hydraulic jacking system, as to increase or decrease the tower body standard mast section, which can lift up or down varies along with the building height.

3. This tower crane's hoisting mechanism have three kinds of working speed, high speed in up and down, speed change smoothly. The highest speed is 80m/min.

4. Slewing mechanisms adopt planet pinion reducer and fluid couplings machinery, Braking smoothly and impact is small, long service life.

5. QTZ7030 Tower Crane widely used with many working modes, and it is applied in extensive projects.
