BHC20A Crawler Crane
1. Original Imported power system, hydraulic system and pilot control system ensure stable performance and sensitive operation.
2. Unique telescopic and crawler design enables the machine suitable for specific conditions, such as under bridges and in tunnels where the height is limited, or where the machine needs to transfer sites frequently, which saves labors of dismantling its boom.
3. The machine can work without outrigger and travel with load.
4. High reliable moment limiter ensures more stable and safer work.
5. High capacity of fuel tank greatly increase time interval of fueling.
6. The extendable chassis not only improve working stability, but also allows transportation of whole machine without dismantling.
7. Capacious and comfortable cabin with broad eyeshot, silicone oil vibration absorbing and adjustable seat.
8. Cast-iron counterweight ensures smaller swing radius.
