Detection and lofting apparatus
1000KN mechanical universal testing machine ( tensile strength, yield strength, elongation, bending, shear and etc.)
Five elements of carbon and sulfur analyzer
The welding quality of ultrasonic flaw detector
Hot dip galvanizing thickness measuring instrument
Theodolite ( 5 ) -- installation verticality measuring tower with
Rebound tester ( measurement of concrete strength)
HP wide-format printers (1.2 meters ) - model, map use
Load test stand 20 meters (for portable base station tower, the cable tower and some non-standard products test)
The galvanization of the steel pole are under strict control. Galvanization is achieved by immersion in a molten
zinc bath(450̊) after pre-treated (dipping).
The metal supports are designed to withstand the nominal force F and the pressure of the wind V applied at 0.25m
from the top. Under these loads, the safety factor with respect to the elastic limit of the steel is larger than 1.8.
The post also resists a torque equal to (F+V) ×1m. Tests shows the load intervened when breaking is around 2
times of design load.
