Luffing Tower Crane LTC5520-16 Advantages:
“Yagong” brand tower crane is the fruit of cooperation between Hebei Yatai company and China Construction Project Institute. Fully utilizing group technology combined design and finite element analysis technology,making full use of the tower crane micro-computer design platform,we manufactured the advanced,most update tower crane. The tower cranes safety and reliable stability are better than our national standard.
Material Control about Crane
1. The steel material that Yatai Heavy Industry use for Topkit tower crane 100% comes from our national large-scale steel corporations.
2. The critical materials of steel,welding material etc are all tested by chemical detection first,then allowed into workshop for batch production.
3. We strictly according to the drawing draft requirements,use 16 Manganese,40 Chromium and 45# steel etc.
4. Every parts of our products like pin,axle,sleeve etc are strictly quenching and testing.
5. Every parts of products are strictly doing according to the procedure requirements:mill,plane,polish,press,test etc.
6. Before leaving the factory,we strictly test according to the ISO9001 Quality System requirements and national standard.
Steel Structure of the products(Luffing Tower crane)
The tower crane mechanical product belongs to special equipment. If accident happens,there will be a horrible result. So our company cooperates with the design institution to reinforces and strengthen main sections with strict procedures and excellent science.
1. Strengthen the force point of the tower crane’s base frame,higher the incline support guaranteed the reliance between the tower crane’s body with the earth contact.
2. Strengthen the force plate and the force angle for the main parts of stand section,to make the tower crane’s body more and more stronger,to improve the tower crane’s body’s resistance
3. Standard sections are double milled to guarantee the contact surface of stand section lies in the same horizon,to bear the average force,to make the tower crane’s bear the force and guarantee the standard sections changable after long-term use.
4. The slewing position of the tower crane’s body the lower and upper slewing platform,slewing and upper slewing platform stronger and bear the average force,to guarantee the slewing mechanism working fluently.
5. The main and secondary chord bar of the Jib boom of the tower crane use the Bao Steel’s seamless steel to weld,to guarantee jib boom flexible and anti-risk.
6. For the main positions of the jib and balance jib, we use bigger the welding size and the strengthen steel plate.
