A total of 8 arm length combinations of 35m-70m can be realized, which can meet the needs of different hoisting environments.The international top stress calculation software is used to analyze the safety of the tower crane structure, and the force on each node of the tower crane is calculated to ensure the overall safety of the tower crane. The three-dimensional solidworks software is used to design, and each component has a high degree of coordination in the design. Ensure that the tower crane runs smoothly. It is among the top high-end in the domestic industry.The PT7015 tower crane adopts laser blanking, with small deformation and high precision, ensuring subsequent robotic welding. Through the turntable welding workstation, the crane arm welding line, and the fully automatic welding line of the chip standard section, the unmanned welding is basically realized, and the post-welding is adopted. Processing technology to ensure dimensional accuracy and product interchangeability. After the steel structure is riveted and welded, the shot blasting, rust removal, and stain removal treatments are performed to increase the adhesion of the plastic powder and ensure that it reaches the Sa2.5 international standard. The surface is clean, the weather resistance is good, and the service life is long.The increase in the weight of the PT7015 tower crane hook is conducive to improving the effect of hoisting wire rope arranging and increasing the service life of the wire rope. The sag of the hoisting wire rope is reduced by 35%, which is conducive to the construction of towers.New frequency conversion faster, more stable and more accurateThe PT7015 tower crane is equipped with a full frequency conversion control system and an intelligent safety monitoring system. It adopts a new generation of rotation vector control algorithm, which has fast start and stop, stable operation, accurate positioning and strong wind resistance. Leading more than 10% of models of the same level. The new hoisting frequency conversion control technology can make the tower crane's hoisting speed as high as 100m/min, and the micro-speed function as low as 5mm/s, and it is equipped with on-load and speed-on-speed technology throughout the entire process. The overall hoisting efficiency is increased by 30%, which is efficient and accurate.Modular design of componentsPT7015 series tower crane components adopt modular design. The common rate of tower crane components at the same level is over 80%. The tower body has high versatility. The new and old tower crane standard sections can be used interchangeably, which reduces user input and improves return on investment.New intelligent security supervision to ensure safety "prevent disease".The new intelligent safety monitoring system adopts dual protection of mechanical and electronic safety devices to monitor the lifting height, luffing range, lifting weight and torque in real time, ensuring the safety of control in all aspects. A video surveillance system can be installed to monitor the hoisting, cab operation, and hook operation in real time, ensuring the safety of hoisting to the greatest extent. It can be equipped with a tower crane attitude monitor to monitor the attitude of the tower crane in real time, remote big data real-time analysis, and an additional layer of intelligent protection beyond the traditional limit protection.cl
