GET TO WORK

Hi! This is another tutorial from ROHR! This is Sales, our assembly supervisor. He's going to teach you how to assemble the temporary access ladder.

First of all, it's always important to talk about workplace safety. I'm here with Edson, who can explain it better.

Okay, Sales. For every activity, workplace safety must always come first here at ROHR. First and foremost, it's very important to emphasize the importance of the PPE (Personal Protective Equipment) we use for this activity, such as helmets, safety glasses, gloves, ear protection, safety harnesses, and safety footwear.

Edson, what is A PR?

Good Sales, a PR is nothing more than a Preliminary Risk Analysis that aims to eliminate or minimize existing risks in the work area before the start of the activity and to investigate some types of interference, such as uneven floors, electrical wiring, or some other type of obstruction.

Great! Let's move on to the assembly. The temporary access ladder can be used in the industrial, construction, infrastructure, and event sectors. The temporary access ladder is very simple to assemble. First, we analyze the location to see if there are any obstructions. Then, we begin the assembly.

Then it's time to install the uprights, always following the ROHR design, which starts with a 0,25 Kibloc post with a rosette like this one.

The rosette is that disc with holes that holds the crossbars and diagonals together, forming a knot. After that, we add the horizontal crossbars.

Finally, we secure the assemblies with the horizontal diagonal fastened to the uprights. Now we'll connect the next posts above the 0,25 post and adjust for leveling.

Next, add the crossbars and diagonals to close and lock the stair ring.

The assembly order is basically the joining of the posts, the closing of the crossbeams, forming two meters, and the placement of the vertical diagonal. After the completion of the first ring, with two meters, they will install the guides, the braces, the steps, the risers, and the internal and external guardrails.

This guide lock is essential because it prevents the ladder from opening and causing the step to fall. After installing the guide lock, we will install the steps. After the steps and guide locks are in place, it's time to install the riser. The function of this riser is to lock the step, thus preventing it from falling.

The mirror installation is complete. Now we'll move on to the external and internal railings. We'll now install the cantilevered landing trestles. It's necessary to secure the trestles with the horizontal crossbar and then place the aluminum flooring on top. Now we'll install a horizontal crossbar to secure the trestles.

Now we're going to install the railing for the landing.

Now, simply follow the same sequence for the remaining landings to reach the height defined in the project. If the staircase is longer than 20 meters, it will have four additional uprights.

Your temporary access ladder is finished. Now it's time to review what we've learned to ensure everything is correct. Check that your ladder has firm and level bases. See if the bracing for the internal and external rails is in place. Finally, check if the treads are locked and if the risers are in place. Now this access ladder is ready for use.
