QTZ40 QTZ50
TOWER CRANE QTZ40 QTZ50
1. Super-long jib arm (42/47/48/50m),
large covering surface.
2. Mast section is large （1500x1500)，well rigidity. The machine keeps stable
with
little oscillation when lifting.
3. Material for main limb of mast section is large(<140x140x12,
<160x160x12).
4. Electric apparatus adopt components of high quality or imported. The
capacity is stable
and trustworthy.
5. Main parts such as standard section, toggle arm and toggle arm adopt CO2
gas. Shielded arc
welding, little deformation and the standard sections are changeable.
6. The performance of speed regulation of lifting frame is well. Raising and
descending
stably and without impact force.
7. Turning gear adopts winding motor or two-speed turning. Operating smoothly
and perching
quickly and conveniently with high efficiency.
