QTZ50(5010A) tower crane is hoisting and conveying machinery which is designed 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 50m and the maximum lifting moment of 500kN•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 25.5kW, 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.

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:Are the creators of the Karate Kid movies apologetic about the white crane defensive stance?: Why should they be? That stance is from an art that is practiced by a small number of practitioners in Okinawa known as Hakutsuru, which means White Crane. It was hollywood-ized... so what? The original movie was written by a practitioner of Goju Ryu, who trained in NYC under an instructor from the Bronx named Kao Loong Ong. He knew there was a link between White Crane and the development of Okinawan Karate. Robert Kamen trained with Kayo, as he is known, who is Chinese and is well known in NYC's China Town. If they should apologize, hollywood must apologize for their misrepresentation of SO many things - insults to practically all the cultures of the world.
