Hello friends, Tower cranes are: Liebherr 50LC working with 4 tower modules of 12m each. Saez S52 working with several tower cranes of 8m and 12m. Both tower cranes will be working with at 30m radius I share: a plan from the project where tower cranes positionS is shown. a picture of a...

Thanks friends, great info. I will make sure to test impact properties from the material I will use to replace S355...

Hello friends, Can you please tell me which is the equivalence on ASTM of S355 J2 G3 steel?? I found a link which sayed it is A575 GR50. Is it correct? Thanks for a fast fact check!!

Hello, We are about to start to mount the metalic structure of a 50m tal building. (12 floor above 00m, 2 floor under 00m). Under ground levels are under construction using slurry wall techinique. Building foundations are reinforced concrete piles. Metallic columns are attacched (welded) to...

Hello, I am working on the design of a multiple-leaf (two rows, five leafs each row) vertical lift gate used as an emergency gate in case of floods to protect an hydroeletric station on the oulet works of a embankment dam. The gate is 11000mm width, 7500mm high. Leaf dimensions 5500x400x1500mm...

Does any of you know where can I get a tool to do this job? Any manufacturer of this kind of tool? Or who has seen mechanical methods to remore this burr in real industry? Thanks a lot

Thanks metengr and EdStainless, I am already working on a device to remove it.

Yes, it is squeezed out to the surface because of the heat and pressure applied. This machining tool is placed on the hot area (when burr still red), or when it is already cold. The burr takes around 25cm to cool down from red.

Hello, I am running a Thermatool HF Solid State Welder for structural beams (100x150mm to 200x460mm) at 12m/min. The output product does accomplish the joint strength code required, but it has a mild burr stuck on the beam web-flange joint. When a client ask to remove the burr for aesthetic...

BigInch, CAD drawings is all the client needs, that is why. The technology used depends on the needs you have. LittleInch, you are right, ISO reccomends isometric views, thaks

I shall make clear I was not asked to design the systems, the systems already exist, but there is no documented information, so what I have to do is to compile all the data on campus and draw it. I just graduated from mechanical engineering, but I already have working experience, so I do feel...

Hello, I need to draw the piping layout of a tuna processing industry. The proyect includes ammonia, vapor, compressed air, process water, etc. Can someone tell me if there is or are any codes or standards for the 2d represention. How do I show when a pipe is going up or down? how do I...

Valuable info EmmanuelTop, thanks a lot

Thanks, spirax sarco is perfect for steam systems. Is there anything similar for compressed air systems?

Hello world, I must design the steam and the compressed air systems for the manufacturing of expandable polystyrene. All elements must be sized and selected (water softener, boiler, steam and air storage tanks, valves, piping, air compressor, air filtes, etc). Can someone recommend me some...

Is it that bad? there is no way to get the problem solved?
