Evaluation and evaluation of the STC7020 flat head tower of Shanxi construction machine     

In July, the new Shanxi construction machine STC7020 flat head tower was successfully passed through type test and field appraisal. In order to make the performance of the STC7020 flat top tower crane more stable, in mid August, the relevant departments and staff members carried out further tests and tests on the tower crane on top of the sun, so as to achieve the design safety performance requirements.

STC7020 tower crane maximum lifting capacity of ten tons, 1.8 tons at the end of crane, jib length 70m, the standard 51.7m. The main purpose of the test is to check the product manufacturing and assembly are in conformity with the requirements of the design parameters and the performance by the company of tower crane department, quality department, welding workshop, engineering test center, tower fleet electro-hydraulic joint workshop. The tower crane division responsible for inspection work; quality assurance department focuses on the performance of tower crane structure, including the main dimensions of the arm raised verticality, meets the design requirements; the main performance engineering test center main hoisting, luffing and slewing test; electro-hydraulic control system is mainly responsible for inter vehicle debugging; a welding workshop tower fleet the main work in this test.

The sun in the sky, the test staff were detected in the cement road surface temperature industrial park near 50 degrees, they see countless check up over, countless times, left and right miss each link debugging tower crane, especially above tower up to more than 50 meters of the staff is not high risk, not afraid of high temperature step by step, climb the scene detection performance. They use high enthusiasm to overcome high temperature, ensure safety with rigorous attitude, and debug with professional technology. With such persistence, we can provide guarantee for safety production of tower crane.
