Getting materials and products across your facility, off of trucks, or onto storage takes various methods. Occasionally it will involve using a support structure that can safely manage the load. These devices spread the weight out evenly or allow you to lift multiple items at a time.

The unit shown here is a bag lifter. It lifts a single 1,000 lb. bag of dry product manufactured at the facility and allows them to quickly move them to a waiting fork lift.

The original unit was worn and in the redesign, we took the opportunity to reinforce the lifting eye with additional material.

Often, such lifting devices have to be load rated. The design will be reviewed by an engineering firm and the final unit structurally tested. At that point, a placard will be placed on the unit noting its load limit.

Here you can follow the job as it moves through the shop. From reverse engineering the original unit, to receiving the parts from the metal shop. Next we lay out and inspect the components. The tack-up process happens and then final welding. A coat of safety yellow (you really want to see anything that is lifted from a crane) is applied.

What’s Up with the Price of Steel?

The cost of steel has tripled! This has been a blessing for the mills in the U.S. that had just recently been suffering. Some have been hiring and even running additional shifts to keep up with the growing demands.

Profits are up as the price and demand for the products continue to grow – but there is a downside to all of this …

 

www.lemonloco.com

 

 

 

 

 

 

 

 

 

New fabrication and repair costs have skyrocketed. Metal quotes that our vendors once held valid for up to 30 days, are now only good until the end of the day! This makes submitting a large quote that will have to go for budgeting and long-term planning difficult for many companies.

Jobs that we had routinely run for clients, have to be re-quoted and adjusted – upward. Some clients are putting off the work while others are trying to find inventive ways to keep the costs down. At times running equipment that should have been repaired or replaced.

The analysts see this current price jump as a bubble and believe it will continue for a short time and then drop drastically. How it will affect the mills who have been riding on the higher profits is hard to say. It’s too early to tell.

But fabricators and repair facilities are hoping for a stabilization so we can help our clients get over the sticker shock they are now facing and prepare for these large capitol upgrades, outages and major repairs.

Model 1841 Field Gun Cannon

1841 Field Gun - Test Fire

 

 

Built by Steen Cannons & Ordnance Works of Ashland, KY, (http://steencannons.com/) this is the test firing of a model 1841 field gun cannon. Riggs Machine milled and turned the cannon from a raw casting. This particular model is made out of cast iron. Steen did a beautiful job with the final assembly.

 

Here is the unit out of the horizontal mill after getting the trunnions machined. It is ready for the CNC lathe.

Mobile Safety Barrier

Traffic Cone

When a Simple (traffic) Cone Won’t Do”

 

Movable Safety Barrier - 3D Render

 

There are several solutions to protecting workers and areas vulnerable to hazards like pedestrian and industrial traffic.

Some companies throw out a few cones, maybe even adding a flag or two for visibility. Then there’s the flimsy plastic folding barriers you might have seen around an out-of-service restroom at the mall.

But these solutions are not suitable for industrial environments. They don’t offer any real protection. They’re just one step up from wishful thinking.

Riggs Machine would like to suggest a better solution: the Mobile Safety Barrier.

This item protects the area around workers while in underground accesses such as manholes and maintenance openings or above ground on ladders.

 

Movable Safety Barrier - Man in Barrier

 

Highly Visible – can be see by those walking around the area and in vehicles and forklifts.

 

Movable Safety Barrier - Side View

 

Due to its sturdy design, it will not fold or buckle in high winds or bad weather. Can be bumped and still remain in position. It’s solid metal frame can withstand the harsh plant environment. Unlike plastic units, it can be painted any color or modified if necessary.

 

Movable Safety Barrier - Caster

 

The Mobile Safety Barrier positions easily on heavy duty casters and can be loaded on a flatbed for quick offsite setup.

 

This convenient, sturdy, mobile, highly visible unit increases safety in your facility.

Handwheel Extensions & Ease of Operation

When a valve handle is not readily accessible, or the distance for proper operation is too great, a Handwheel Extension might be the solution.

Once affixed to the existing valve, workers have quick, ready and safe access to the controls when need arises.

 

 

 

 

 

 

 

 

 

 

Shown above, an inaccessible gate valve is below a platform. With a bolt-on Handwheel Extension, a worker on top of the platform now has convenient, safe access within reach and can operate the valve freely (without the need of ladders or rigging).

 

 

 

 

 

 

 

 

 

Also, by increasing the diameter of the handle on the Handwheel Extension, the valve may be easier to operate than it may have been with its original smaller handle.

 

 

 

 

 

 

 

 

 

 

These Handwheel Extensions are custom designed based on the valve size and distance from the valve to the operator’s control location.

 

 

 

 

 

 

 

 

 

Handwheel Extensions are often galvanized to help withstand the weather, elements and possible corrosion from chemicals in the facility.

 

 

 

 

 

 

 

 

 

 

If you have inaccessible valves that require outside rigging to operate or controls that put your employees in dangerous situations, call Riggs for an overview of the benefits that Handwheel Extensions can offer.

Precision Shafts to Get You Running Again!

They say “wheels make the world go round”, but without shafts, nothing would ever move.

 

3D Render of Shaft

 

 

 

 

 

 

 

A shaft connects a mechanical power source to gears, wheels, turbines, rotors and much more. Shafts can be as simple a basic round bar or as complex as containing exacting bearing fits, keyways, sleeves, grease fittings, snap ring grooves and splines.

 

Broken Shaft – Removed from Assembly

 

 

 

 

 

 

Often, the shafts we see have been in service for many years, sometimes running non-stop. Unfortunately when these older shafts break (as shown here), there aren’t drawings available and not a lot of time to get the new shaft machined and the unit running again.

 

Half a Shaft – Part A
Half a Shaft – Part B

 

 

 

 

 

 

 

 

 

This shaft broke and we got it in 2 sections, still in the housing. After disassembly, we made hand sketches. While the housing was cleaned and checked, we created 3D drawings and then machined a new shaft.

Here is the new shaft ready for inspection. After passing final inspection, the housing was reassembled and the unit was ready for production use.

Hopefully a broken shaft won’t take one of your machines, or worse, your facility down. But if it does, Riggs Machine has the experience to get you running again.

A Fabrication Story – The Bearing Pedestal

Pedestals – Old and New

 

 

 

 

 

 

 

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.

 

Pedestal – Old Unit – Front
Pedestal – Old Unit – Side

 

 

 

 

 

 

 

 

 

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.

 

Pedestal – Hand DWG
Pedestal – CAD DWG
Pedestal – 3D Model

 

 

 

 

 

 

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.

 

Pedestal – Pallet of Parts

 

 

 

 

 

 

 

 

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.

 

Pedestal – New – Stage I
Pedestal – In Process – Rear
Pedestal – In Process II

 

 

 

 

 

 

 

 

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 Platform Handrail – Ergonomics and Safety

Industrial platforms and walkways typically use one of two types of handrail – round bar or angle.

round rail platform

updated angle based handrail

 

 

 

 

 

 

 

But recently we’ve seen the addition of a lower handrail, which is more ergonomic and comfortable.

smoother, more ergonomic grip

 

 

 

 

 

 

 

 

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.
