Motor-driven planetary gear reducer system lifts main/auxiliary hooks via drum and pulley set. Features built-in planetary reducer and normally closed "spring brake/hydraulic release" system for safety. Uses high breaking force wire rope (φ26mm diameter).
Motor-driven planetary gear reducer achieves main arm luffing through drum and pulley set. Includes built-in planetary reducer with normally closed brake system and ratchet locking device (hydraulic cylinder driven) for multiple protection. Uses φ26mm high breaking force wire rope.
Internal meshing drive with slewing bearing enables 360° rotation. Features built-in planetary reducer with normally closed brake system and mechanical slewing locking device for enhanced safety. Includes free sliding function.
Engineered for large load-bearing capacity, minimal slewing resistance, wear resistance and extended service life.
Power pin connections (oil cylinder driven) between boom/turntable, frame/track beam, and counterweight tray/turntable. Includes mast lifting, outrigger, and track tensioning cylinders for convenient installation. Control room features oil cylinders for vertical flipping and horizontal rotation.
Bionic design provides wide field of vision and comfortable, convenient operation.
Box-type radial structure welded from high-strength steel plates delivers excellent overall rigidity and strength.
