Internal Climbing Tower Crane Qtz125 (TC6515)
Mudsill standard configuration is grand cross beam with poles style.
Main body section is 160by12 angel steel, lengthen the adapter sleeve, increase the weld joint length, lengthen the high-strength bolt, increase the strength of weld and link. Higher the safety. note plate machining chamfering after welding, ensure the weld penetration. Node plate was extended the widened and increased the strength make for the transmit of force. Increased the standard section of the fatigue strength and stability. Welding is double-sided milling machine group machining to ensure the flatness in each section. The machine moving small to further improve the security
Main body section and turntable welding adopts robot welding system. Stable property, high degree of automation, good appearance of weld and the welding quality is stable.
Compared with the other manufacturers, the climbing frame have more height and increased the safety of the jack-up.
The tower boom tube structure is square tube structure, trolley adopts Q345B (manganese steel) material, tensile strength increased by 30%.
Haiyang luffing mechanism of planetary gear, maintenance-free, low maintenance rate.
All welding gas adopt argon, carbon dioxide gas mixture, forming good appearance, large depth of molten weld quality is stable.
The cab's iron plate thicken, tempered glass, safe and reliable.
