SQ250A Hydraulic Crawler Crane for piling , 1.79rpm Slewing speed 3m Lifting range
Telescopic Crawler Crane is a kind of new generation products. Mainly used for piling at construction site, bridge construction and tunnel construction, especially in the work place such as deserts, swamps.
It's advantage is
1. don't need to assemble and disassemble, convenient for transport, and go to another site in the construction site.
2. cannot be limited by the space smaller.
3. big cross-country ability.
4. able to achieve load driving
