Industrial Platform Handrail – Ergonomics and Safety

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.

Grapple – A Hook or Claw to Catch or Hold

And boy do they!

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.

 

The Target Blind – Revisited

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.

Primary Air Fans

Primary Air (P.A.) fans force air into the furnaces of coal-fired power plants. Rotating at 1,600 RPM, they have to be solid, balanced and reliable.

 

Here is a new P.A. fan. It has been welded and the center hub riveted. The welds are then inspected to AWS D14.6 Standards using Magnetic Particle Inspection.

 

The fans are then balanced; much like you’d balance the wheels on your car. The shafts are also balanced and a mated set is created to ensure smooth rotation and a long service life.

 

The Gator – First Test

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.

Boiler Boxes – Refurbished

In a hot-job shop you never know what will come through the doors.

Take these worn boxes that attach to the sides of boilers. We needed to reuse some of the components, but build new, stronger frames.

These new Boiler Boxes will fit just like the old ones, but last a lot longer.

Boiler Face Plate w/Expansion Folds

A boiler gets hot, really hot. And when it does, the walls expand.

To help control expansion, one solution is to cut slots in the walls and weld “Expansion Folds” over top of these slots.

This gives the plate a little more room to expand as the pressure builds in the unit. They are placed around the plate helping it expand as it heats.
