1.Main winch uses two synchronous working speed reducer,slewing ring and slewing gear are external coupling and dual drive.
2.Crane frame is box type structure with inner reinforcement and slewing ring is added with necessary plate, which ensure effective load transfer and overall rigidity and strength.
3.Structural parts are designed with FEM for optimization,reasonable load bearing and light-weight.
4.Car-body is I-type,simple structure,good rigidity,and reinforcement plate is arranged around the swing center for improving rigidity.
5.Crawler frame is welded box type structure,connection between lower roller and frame is added with necessary reinforcement plate,and crane travel is single side and single wheel drive.
Self-erecting the parts that is greater than 15t,hydraulic assembly of the linking pin shafts between turntable and boom.
Lift or lower the basic machine by extending or retracting the outrigger cylinder and self-erecting is realized.
