6-section large cross-section elliptical boom；topological optimum design for structure; the strongest lifting performance of the same tonnage.

2-axle special chassis with large outrigger spans and multiple combinations of counterweight; high flexibility and good stability; more suitable for lifting high and far.

High-efficiency electric proportional constant-power load-sensitive pumps and high-response and high-resolution proportional valves provide stable control output; “high speed for light loads, low speed for heavy loads” guarantees precise operation and faster response.
