Galvanized Thrie Beam Guardrail
Galvanized Thrie Beam Guardrail
Hot dipped galvanized Steel Guardrail /Highway fence and guardrail posts are mainly used for safety traffic barrier protection on highways and first-class highways at home and abroad. Q235 material is used domestically, and Q345 material is used abroad. The steel plate is formed by cold bending and then galvanized and electrostatically sprayed.
Highway Steel Barrier has strong corrosion resistance, bright and beautiful appearance, and high anti-collision strength, which meets the standards of the Ministry of Communications. , In line with GB / T31429.1-2015 "Anti-corrosion Conditions of Expressway Traffic Engineering Components" standard. Requirements of "Waveform Steel Guardrail Part 1: Double Waveform Motorway Guardrail"

An important part of the crane trolley line indicator is used, but due to the imperfections of the traditional indicator lights, the trolley cable often has electricity, which poses a great safety hazard.
Most of the cranes use multi-stage slewing line, single-stage slewing line, rigid body slick line, and angle iron to provide power. The system's indicator lights are mostly made of ordinary incandescent light bulbs. Due to the defects of incandescent light bulbs, the indicator light can easily burn out. Slip wire has electricity, but the phenomenon of light does not light, it is easy to produce the illusion of no electricity, there are security risks. And frequent replacement will increase business spending.
Now, our company's indicator light overcomes this drawback. It has been promoted and applied in some large and medium-sized enterprises in the country. It is believed that the safety issues of crane trolleys will be more and more important in the near future.
At the same time, in order to effectively ensure the use of the trolley line, it is recommended that the staff must detect the trolley line in peacetime. Check whether the straightness of the track has obvious deviation (more than 20mm), misalignment, whether the insulation protection parts are detached, broken or damaged, whether the stainless steel “v†groove is tilted or not, and whether there are foreign matter and conductive dust on the track. If necessary, check whether the insulation resistance meets the requirements (interphase insulation resistance should be ≥10MΩ).
