What type of bridge is the golden state bridge a i beam girder or a box girder?
beam girder
What construction method was used to build the London Bridge?
The current (1973) bridge is a pre-stressed concrete box girder bridge
What is a box gider?
Do you mean box girder?
What is the purpose of the box girder?
It is a technique in civil engineering. Parts of a construction are prefabricated it box sections, transported to the site and added to the existing sections. It is particularly useful in bridge building.

What type of bridge is a namihaya bridge?
The superstructure is steel box girder
What kind of 4 bridges are there?
cable stay, arch, suspension, box girder
What are the disadvantages of box girder bridge?
The disadvantages of a girder bridge is that it's expensive to build. It is also very hard to maintain. It needs to have access to the confined space of the girderbox.
Why does honeycomb girder gantry crane have a potential market?
Zhengzhou Huazhong Construction Machinery Co., Ltd. (ZZHZ). Thanks for asking the question about honeycomb girder on Answers, because it is one of our patents. Honeycomb girder developed for gantry crane and bridge girder launcher by our company -----Zhengzhou Huazhong Constrution Machinery Co., Ltd ( short for ZZHZ ), which is a new type of main girder and has been widely used in crane fields. The reason why increasing people are looking for honeycomb girder type cranes because they are unique and reliable.Brief introduction on honeycomb girder gantry crane and bridge girder launcher are as following.1. Why we called it honeycomb girder?The main girder is honeycomb girder.For honeycomb girder, it means many hexagonal holes which looks like honeycombs in the main girder, with which the air current could pass through the hole when the launcher works high above the ground. Then it greatly reduces wind impact on the gantry crane, so it is quite safe.2. What are Advantages of honeycomb girder?a. compared with truss girder, safer!Steel plate welded with steel plate (honeycomb girder) is safer than point to point welding (truss girder). If there is an occasional bad welding, the honeycomb girder will not be affected too much, while if it happens on truss girder crane, the whole girder may lose stability and cause an accident.b. Compared with box girder, safer!When box girder crane works high above the ground, the heavy wind will have a great impact on it and make it unsafe. While the honeycomb girder launching gantry has reasonable design(honeycomb hole) to reduce wind impact. Besides, it has a light self weight and cost lower.3. Featuresa. quite safeb. high wind-resistance, high stiffness and low deflectionc. light self weightd. flexible legse. unique and reliable pin connection, easy installation and disassemblyf. high quality imported electrical elements are used4. LimitationAt present, if material to be lifted is less than 250t, a honeycomb girder can be used.Generally speaking, with its own characteristics, the new style honeycomb type gantry crane and bridge girder launcher from ZZHZ will be the flavor of the market.Please find more information about honeycomb girder on website of Zhengzhou Huazhong Construction Machinery Co.,Ltd.
