On the afternoon of March 25th,Zoomlion Changde Tower Crane Intelligent Factory,Zhonglian Round Mortise Tower Crane Two-person Jacking Technology Release Meeting Successfully,Safer、Easier、Faster、New and more economical Tower Crane jacking operation mode,Causing widespread concern and enthusiastic response in the industry。
Driver+ Assistant
Two-person jacking means that two persons on the tower complete the jacking operation of the whole standard section of the tower crane,Driver+ Assistant This is done,Two people have clear responsibilities.、Clear division of labor,Process-based operation、Normalization,Live demonstration of the press conference,One-section standard section jackingThe whole journey takes 20 minutes.,Compared with the traditional tower crane, the lifting operation efficiency is improved by 50 percent%。
2 advantages+Five major transformations
Round tenon tow crane based on ZoomlionSingle pin connectionAndMortise and tenon guideTwo advantages and climbing system“Tian Cao moves down to the climbing frame、Hydraulic pin pulling、Jacking beam guide rail、Electric safety pin、Electric Introduction Standard Section”Five major transformation technologies,On the basis of a small number of people, the two people still achieved safety.、Relaxed、Quick、Economy。
Five major transformations①:Tian Cao moves down to the climbing frame
Two people are equipped with intelligent operation box on the tower body.,Ask the tower crane driver to come out of the cab.,Operate the three mechanisms of tower crane,And operate that jacking system,He also assisted the assistant to complete the work of driving the pin shaft.。Driver-led、Assistant cooperation,Clear division of labor,The operation is orderly。
Five major transformations②:Hydraulic pin pulling
In the traditional tower crane jacking operation, the installation and disassembly of the connecting pin shaft between the jacking section and the tower body are time-consuming and laborious.,The installation and disassembly of the connecting pin shaft between the lifting section and the tower body in the two-person jacking are completed by the hydraulic system.,4 pins in 1 minute,Quick and easy。
Five major transformations③:Jacking beam guide rail
Increase the guide rail of jacking beam,When ensuring the extension of the oil cylinder for lowering the tower,Jacking crossbeam automatically hanging into step,Installation personnel do not need to climb into the tower body to hang the jacking beam.,The operation is more humane、Safer。
Five major transformations④:Electric safety pin
The safety pin in the traditional jacking also requires the installation personnel to climb into the tower body to pull out.、Plug in,The operation is inconvenient,The motorized safety pin arrangement reduces repetitive movement by the installer,Make the tedious operation simple and easy。
Five major transformations⑤:Electric Introduction Standard Section
The traditional manual introduction standard section is changed into electric introduction.,More uniform introduction process、Smooth,And that operation is simpl and easier。
Safe、Relaxed、Quick、Economy
Jacking operation is the link with the most safety accidents of tower crane.,Therefore, jacking safety is also the most concerned issue in the industry.。Zoomlion's round-tenon tower crane is lifted by two people through two core advantages of round-tenon joints and five major transformations of climbing system.,At the same time, it is equipped with voice intelligent reminder、Logic sequence control、Clear division of work between driver and assistant,More effectively promote the standardization of jacking operation process,Bring to the industrySafer、Easier、Faster、More economicalJacking operation。
Many safety supervision departments praised this.,It is believed that the two-person jacking technology will lead the development of the industry.,And has great popularization value.。
