Key feature

1. Employed rigid drag rods of 2-sustained center can ensure tower crane’s rigid and strength. The rising structure can automatically install the drag rods itself, safely and conveniently.

2. The L-rising structure employs a planet-bevel gear and a quad-speed motor to regulate working speed. This unique design can effectively expand the wire cable’s capability, stabilize hoisting the underloading while at the high speed and take position correctly while elevating the oveloading at the low speed.

3. Rich working space and light deadweight ensure its outstanding hoisting capability.

4 .Wide nominal hoisting force moment plus lower power consumption can increase its productivity obviously.

5. As for all steel structures, the employed carbon dioxide welding can ensure them to be well-set and reliable in the quality.

6 .Side and freestanding cab is wide-field with enough inner space where the ganging control console and a soft chair to be equipped for a convenient operation.

7. 2 sets of gyration structure, with better resistance to shock, runs synchronously and reliably.
