There’s a reason for the fabricating in Riggs Machine & Fabricating. Here’s a perfect example. A client has an older machinery pedestal in very poor condition and needs a new assembly. There are, of course, no design drawings for the item, but luckily we can bring it to our shop.
First we make hand sketches of the unit. We review the original design to see if there were any structural defects that should be improved or any new features that the client would like to have implemented in the current design.
Next, these sketches are converted to CAD drawings and then 3D models are created for fit-up and testing. It’s much faster (and cheaper) to test a new design in 3D than it is after cutting 1/2” thick plates. When we are satisfied with the design, the files are sent out to have plates cut.
This is what we get back from the waterjet cutters (Swift Manufacturing), nice pallet of loose parts. Now fabrication begins. If the designers did their work properly, the welders job should go smoothly.
And here we have the final assembly. From hand sketches to CAD to 3D models to cut parts to fabrication in less time than it takes some companies to return your call.
Industrial platforms and walkways typically use one of two types of handrail – round bar or angle.
But recently we’ve seen the addition of a lower handrail, which is more ergonomic and comfortable.
This additional handrail makes transversing stairs much safer. There are no breaks or pinch points as you move your hand along the rail. The placement is more convenient and it just has a better feel to it.
Even better, this handrail can be added to existing walkways and platforms. If you have a heavily trafficked area or a thoroughfare on which you’d like to beef up the safety – rather than replace the entire structure, consider this simple (and cost effective) addition. Give Riggs a call, we’re here to help.
You may be familiar with the design, it has been used for years from junk yards to the toy dispenser in the mall arcade. The reason is simple, they work. The four finger design can lift almost anything. This is very handy in a scrap yard when you never know what is coming in next or the condition an item may be in.
This set is from a metal yard and they are abused on a daily basis. They pull scrap from rail cars and trucks all day and drop it into awaiting shredders and barges.
To extend the life of the hooks, the ends are cut off and new tips are welded on. All four “fingers” are replaced at the same time to keep balance and even wear of the unit. The key is making sure all four tips line up and meet in the center of the unit, ensuring maximum performance. Not an easy task on such a large and unwieldy assembly.
Here they are, ready for assembly on the unit. Soon they will be helping in the cycle of converting scrap into metal that will go back to the steel mills to make new products.
Blinds, sometimes known as blanks, isolate a section of pipe for repair, maintenance or testing. There are many types of blinds as we have shown before from the slip blind, the spectacle blind to the bleeder blind.
Here we have a nice assortment of Target Blinds. Used much like the bleeder blind, the target blind is placed on the end of a pipe section rather than in the center of a section. Gauges can be placed on the valves to test the pressure in the section of piping. Sampling can also be taken from the valve if desired.
The different sizes correspond with the different sizes of piping found within the refinery.
This group of target blinds is a bit “beefier” than usual. They will be used during the permanent shutdown of a unit until the demolition of the unit occurs. There may be need for occasional venting of the piping section until the demo.
The Gator is a remote controlled tank cleaning unit we built for Veolia Environmental Services. It is driven into large tanks to clean the walls of hazardous materials. Its infrared lights cut through the dark and mist while recording all operations from the safety of a control booth.
This is a test of the unit running up a ramp and squeezing through a manway as it would enter a tank in the field.
