Vantaggi e funzioni

Sany STC900T truck crane is designed with five-section boom that is made of high strength steel structure and optimized U-shaped cross section. Its maximum lifting capacity is 90 ton, full-extended boom length of 50m.

Superior lifting capacity

Five section, U Shaped main boom, the length of full extended main boom is 50 meters long, the longest in the industry. The longitudinal span is 8m with 16.1t full counterweight, the lifting capacity is leading the industry over 15%.

High bearing capacity of chassis

Brand new chassis with 2.8m width, the frame with rectangular cross section is more higher and wider, The lifting capacity of anti-torsional and anti-bending have been achieved comprehensive enhancement.

Electro-hydraulic proportional hydraulic system

Lifting energy saving capacity would be increase 15% by using electric control system than hydraulic control system, the heave load working efficiency would be increase 30%. The composite operation would be more coordinately and smoothly by using intelligent flow compensation and the utilization of flow would be increase 20%.

Humanized control system

New humanized design with handrail and ladder, the widened operation cab can move upward from 0 to 20 degree with new inner design, new air supply design of three dimensional air condition provides more comfortable and more wider working environment.
