ADJUSTABLE LEG LOCK FOR ALUMINUM SCAFFOLDING

ADJUSTABLE LEG LOCK FOR ALUMINUM SCAFFOLDING

ADJUSTABLE LEG LOCK FOR ALUMINUM SCAFFOLDING

THE ADJUSTABLE LEG LOCK IS A MECHANISM THAT LETS THE ADJUSTABLE LEG SLIDE IN AND OUT OF THE SCAFFOLDING FRAME. Aluminum scaffolding cannot have more than 12 inches of adjustability in its legs. For the adjustable leg to have a true 12 inches of adjustability the leg needs to have 13 inches of thread (will talk about this in another section).  The adjustable leg lock is a mechanism that unlocks a split threaded nut allowing the adjustable leg to slide in and out freely.  When you’ve reached your desired length you lock it by pushing the outer ring straight down. This will engage the threads of the split threaded nut into the threads of the adjustable leg.

If for some reason the ring will not slide down just slide the leg in or out just a little. What is happening is you’re trying to mesh a thread on top of another thread. So by moving the leg either in or out a little bit the thread will slide into the threads of the leg.

How it happens:

The leg lock mechanism consists of a split threaded nut and a knurled ring that when lifted and twisted up releases the split threaded nut which expands out releasing its threads from the threads of the aluminum leg.  This then gives you the ability to slide the aluminum threaded leg in and out of the base frame. This gives you the ability to level your scaffolding on un-even surfaces or to help you get over objects. The adjustable legs are never to be used to gain height. Please refer to your instruction manual.

Damaged adjustable leg lock:

A picture is worth a 1000 words regarding this damaged adjustable leg lock. The adjustable leg lock is held in by a set screw. As you can see the set screw was missing from the adjustable leg lock mechanism.  The customer secured the leg lock mechanism with a wire wrapped around the adjustable leg lock mechanism and over the horizontal rung.

The customer I can only assume tried to fix this in the field. What happened is he wound up holding the ring to the leg lock mechanism open. So the leg was not secured in the frame and could slide out if the scaffolding were rolled over a negative area. All the customer needed was a set screw and a screwdriver to fix the problem.

Conclusion:

I would highly recommend when it comes to parts of the scaffolding like the adjustable leg lock mechanism, adjustable legs, short pin, long pin interlock clips and bushings that the customer carries these with them at all times. The adjustable leg mechanism in the other mentioned above parts are field replaceable. So read your safety manual, carrier spare parts and the tools to make the repairs in the field.

UPRIGHT S.N.A. AERIAL WORK PLATFORMS / CASTERS

 

ISSUE:

Casters taking major abuse?  Upright SNA aerial work platforms/casters will show you how to take steps to prevent small problems from turning into large problems. Upright SNA aerial work platforms/casters is a brief informational on our casters, their use and their abuse.

REASON:

Because the casters are on the bottom of the upright scaffolding or your aerial work platform. They are the last to be looked at until there is a problem. Normally we check the structure of the scaffolding as we build it. The aerial work platforms we normally just jump up onto and go up. We have become too trusting with our equipment. Remember you’re in control of your Upright SNA Aerial Work Platforms.

PREVENTION:

To prevent problems with your UPRIGHT SNA AERIAL WORK PLATFORMS / CASTERS, start by reading the instruction manual.  It takes 10 minutes and will save you time and money. When inspecting your equipment start at the bottom with your casters. Check them for string and other debris. Make sure the brakes work by pushing them down to lock them and pulling up on the lever to unlock them. Check to make sure your Upright Aerial Work Platform casters rotate side to side easily with the brake-off. So if you check your casters every morning and look for string and other debris that can wrap itself around your castor. Now is the time to remove it not later. By ignoring this and using the scaffolding the string or other debris will continue to wrap itself tighter and tighter around your castor hub. Once that happens you will need to take your castor apart and clean out the debris and then reassemble your castor. This will take you about a half hour to 45 minutes per castor. This equates to time and money.

,FIX MY ALUMINUM SCAFFOLDING EXTENSION FRAME

 

DAMAGE:

To fix your aluminum scaffolding extension frame we will need to know the problem. This three rung double wide extension frame is missing its bushings.

The missing bushings are what connect the extension frame to the bottom frame. After time these get beat up or lost.

FIX IN THE FIELD:

Fixing your aluminum scaffolding extension frame in the field requires the replacement bushing and the self-tapping screw. You will see from the pictures below the sequence process for replacing the bushing in the field.

This double wide extension frame is missing its bushings.
This shows them lining the holes up and getting ready to insert the self tapping screw

 

This shows the missing bushings at the bottom of the frame and the self tapping screws hole connecting the bushing to the frame

 

this shows bushing in place for self tappiing screws inserted
this shows the bushing in place and the self tapping screw and place. This frame is ready to go.

 

PREVENTION:

Read your owners manual regarding maintenance. By checking your scaffolding daily before it goes out you can catch loose screws or broken rivets. These are the two methods of connections that are used by the manufacturers for connecting the bushing to the frame. It takes less than 10 minutes to read the manual and that time can save you hundreds of dollars.

CONCLUSION:

In fixing your aluminum scaffolding extension frame you will need to know the problem in this situation it was the missing bushings. As you saw above they are easy to replace and if you have any questions please feel free to call me Joe foot at 707. 799. 8902 or email me at Joe@uprightsna.com.

DAMAGE SCAFFOLDING

DAMAGE SCAFFOLDING

 

HOW DOES THIS HAPPEN?

Damage scaffolding starts with abuse. Abuse equals misuse.

If a person does not know how to use something like upright aluminum scaffolding they will wind up misusing it and in turn damaging the scaffolding. The pictures below reflects this abuse. The damage to these parts were the result of someone not knowing how to use the scaffolding properly.

Safety clip damage. They ripped between the locking hole and retaining hole
Tour between the locking pin hole and the holding position hole

 

HOW TO PREVENT DAMAGE:

Read the scaffolding manual. It will tell you how to use the scaffolding properly. How to set it up properly and tear it down. The instruction manual will talk about scaffolding maintenance. Now taking 10 minutes to read this will save you a lot of money. Train your people on the proper use of the scaffolding. This will prevent damage due to not understanding how to properly set up and tear down scaffolding. Understanding how to use the scaffolding would prevent the above damage.

 

CONCLUSION:

We all spend a lot of money on scaffolding so take the time to read the instruction manual. 10 minutes of time can save you hundreds of dollars. Damaged scaffolding starts with abuse. Abuse equals misuse. So take some time to train your people on the property use of your scaffolding.

COUPLER

COUPLER

COUPLER

I am going to present one COUPLER. Which  can be used as a right angle COUPLER, in-line COUPLER or a swivel COUPLER.  You can do this just by adding or removing a roll pin.

WHAT IS A COUPLER?
A Coupler is a device that joins (couples) tubing together by griping around the tubing.  The type of Coupler we are going to discuss works with 2” O.D. Aluminum Scaffolding and tubing. Most Couplers come either as a right angle Coupler, in-line Coupler or swivel Coupler.

DIFFERENT TYPES OF COUPLERS:
There are three types of couplers, the right angle Coupler, In-line Coupler and the swivel Coupler. If you wanted to join two pieces of aluminum tubing at right angles you would have to buy a right angle Coupler and the same if you wanted to join two pieces of tubing parallel to each other you would buy an in-line Coupler and the same for a swivel Coupler.

ONE COUPLER THAT DOES WHAT THREE COUPLERS DO:
This is what I call a Universal Coupler. It can be configured as a swivel Coupler, a right angle Coupler and an in-line Coupler by just adding a roll pin in the proper hole for right angle Coupler setting or in-line Coupler setting. To use as a swivel Coupler you just remove the pin and the two halves swivel.

CAUTION:
Most Aluminum Scaffolding uses thin wall tubing .058 wall thickness. That is the reason for the wing nut for tightening. If you use a wrench to tighten the coupler DO NOT over tighten or you may crimp the Aluminum Scaffolding tubing.

— USES:
Have you ever had a job that you cannot access with an Aerial Work Platform or with your standard Aluminum Scaffolding?

What you need is a special Access Work Platform.

You might need to have a special Access Work Platform built which would most likely use Couplers or you might be able to use your existing Aluminum Scaffolding with just the purchase of some Universal Couplers, some heavy wall Aluminum tubing and maybe some extra frames.

The NASA AMES 40 by 80 wind tunnel use standard Double Wide Aluminum Frames with 10’ platforms and bracing along with swivel and right angle Couplers to span completely around the 40’ turbine engine.

There were a lot of swivel couplers used on this project 40 x 80 wind tunnel at NASA Ames

The Tibetan Gallery was just a standard six foot Aluminum Scaffolding Tower with a platform height of 17’ 6” and no outriggers. The Aluminum Scaffolding Tower was supported by special made brackets mounted to the wall and tubing with just the Universal Coupler used in its right angle and swivel Coupler settings.

CONCLUSION:
When the Aerial Work Platform does not work take a look at using your existing Aluminum Scaffolding and either renting or buying the extra scaffolding pieces and Couplers to access the job.

Aluminum Scaffolding, Short Pin Interlock Clips

Aluminum Scaffolding, Short Pin Interlock Clips

Aluminum Scaffolding, Short Pin Interlock Clips

Short pin interlock clips what are they used for?Short pin interlock clips are used on your aluminum scaffolding to hold the frames together. Short pin interlock clips are easy to use and field replaceable if lost.

aluminum scaffolding

How to use your short pin interlock clips:

There are two holes at the top of each frame. The bottom hole is used to hold the interlock clip while not in use. The top hole is used to connect the two frames together with the short pin interlock clip. You will notice on the short pin interlock clip that there is a positioning line. This line should be at the bottom of the short pin interlock clip when positioning it in the top hole or bottom hole. If the positioning line is at the top of the short pin interlock clip, the clip will not be able to fit into top hole. This is due to the pin being offset making a clearance issue between the short pin interlock clip and the bushing of the scaffolding frame.

The short pin interlock clip is made to stay on:

The short pin interlock clip is made of sprung steel. The reason for this is for the ability to pull the clip apart a bit and slide it down into the bottom hole or up into the top hole without having to pull it off the scaffolding. This is why the ends of the short pin interlock clip are bent inwards. This gives you a place to grab when pulling the pin apart as well as preventing it from coming off the scaffolding frame.

Conclusion:

Short pin interlock clips are used on your aluminum scaffolding to hold the frames together. Always use short pin interlock clips that are made for your brand of aluminum scaffolding. Do not use other items to hold your frames together for example nails, screws, miscellanies metals, etc.
