SANY STC250T5 TRUCK CRANE 25T LIFTING CAPACITY. Technical Specifications & Load Chart

Model STC250T5 | SERIES

SANY TRUCK CRANE

STC250T5 / 25T LIFTING CAPACITY

Strong boom

■■

41m telescopic boom in five sections lifts to a new height

of 41.5m, and further to 49m with jib mounted.

■■

Larger cross-section boom, achieving a load moment of

1063kN·m.

■■

Boom section overlap increased, resulting in higher

torsion resistance and bending resistance.

Powerful chassis

■■

DF Cummins ISLe290 30 engine, FAST 9-speed

synchronizing gearbox, rubber suspension, 12R22.5 wire

tire.

■■

Frame torsion resistance verified by 20k times of

reliability and safety cycling test.

■■

Outrigger span expanded to 5.18m×6.4m, providing a

stable base.

■■

Low deck chassis enhances travelling stability.
