Steel Structure Highlights
Using the national standard Q235, Q345Bmaterial profiles, high capacity, long life;
Platform railings and all the smallcomponents of tower crane are made of hot dip galvanizing process, ensuring10--15 years of use.
Machine blasting pretreatment, surface Rustgrades and preparation grades are Sa2.0-2.5 level. Spray paint are divided,roast process, customers can freely choose according to demand, once theoverall paint can meet five years of continuous use.
You can install a standard section toincrease the height of the tower, it is widely used in climbing or enclosingthe large tower crane dismantling of auxiliary equipment within high-risebuilding
After the lifting operation is completed,the machine can be broken down into different weight of widgets and easilyreturned to the ground through human or construction hoist.
It can be customized according to customerrequirements.
Electrical control system highlights
Three institutions use inverter technologyto achieve zero speed brake, running smoothly without impact, greatly improvethe safety performance.
Real-time monitoring system to facilitatethe understanding of the roof crane usage, to achieve a true sense ofintelligent management.
Electrical components are used well-knownbrands.
