QTZ63 (5013B) tower crane

QTZ50(4810) tower crane is hoisting and conveying machinery which is designed by Shandong Fuyou Co., Ltd. by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 48m and the maximum lifting moment of 544kN•m. The tower crane has the lifting height of 30m and the adhesion lifting height of 120m (2 magnification) during independent use.
All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 24.9kW, features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many medium-small construction enterprises.

2.1 Lifting Performance Table and Lifting Performance Curve
(1) 4-magnification Lifting Performance Table

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q: Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?: 6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.

Q: feminists always point to sexism. but Ive found 3 women here - who say they have experienced no sexism, and were pleasantly surprised by how excepting their largely male co-workers have been -: Because manual work is the domain of the working classes, and the further down the social heirarchy you go, the less effect feminism has had. People from working class backgrounds are more likely to have broadly traditional attitudes towards work. This will change. I know young working class girls who are training to be plumbers and electricians. Hopefully their daughters or granddaughters will be operating cranes and working on building sites.

They are designed by structural and mechanical engineers to loift a given weight.
