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.

Why do the bridge pins keep popping out of your acoustic guitar when you change the strings?

As the ball end of the string begins to wear the bridge plate a common problem is flying bridge pins. Have you ever tried restringing your guitar only to have the pins pop or fly out when tuning the string to tension? Usually, when a bridge pin will not stay put, wear on the bridge plate is allowing the ball end of the string to pull up and into the plate instead of locking itself against the plate. It could also be a very poorly fitting pin. If wear on the bridge plate is extensive a bridge plate veneer or plugs can help. Another tip which is quite helpful in this instance is to bend a slight hook in the end of the string when replacing the strings. This small "hook" will help the string to catch the edge of the plate and avoid being pulled up into the plate. When the ball end of a string wants to pull into the bridge plate hole the bridge pin must then smash or wedge the string in the hole to prevent it's slippage. Ideally the ball end of the string hooks around the edge of the plate and the bridge pin holds it there. On an instrument without problems or excessive wear it is even possible to remove a few treble string bridge pins when it is strung to tension. Though I do not recommend it, it illustrates the physics.
