Erecting a Mobile Scaffold Safely: A Step-by-Step Guide for Professionals

Properly assembling mobile scaffolds sounds easier than it is. Most accidents involving mobile scaffolds do not occur when working on the platform, but rather during assembly and disassembly or due to faulty assembly that fails later. This guide explains safe assembly step-by-step and lists the most common mistakes that frequently occur in practice.

Before assembly: Clarify these points first

Before the first frame is erected, the ground should be checked. Mobile scaffolds stand on castors, which require a load-bearing, preferably level surface. There is a risk of tipping on loose ground such as sand, gravel, or yielding soil. The manufacturer's assembly instructions must be available and followed – deviations will invalidate conformity with standards.

Also clarify: Is there sufficient clearance to overhead lines, roof overhangs, or other obstacles? What maximum working height is required and is the scaffold designed for it?

Step-by-step: Assembling a mobile scaffold

Step 1: Lock the castors. The brakes of all four castors must be activated during assembly. The scaffold must not move during assembly.

Step 2: Assemble the base frame. The two base frames are set up and connected with each other via the cross connections. Ensure all couplings are correctly locked.

Step 3: Add frames. Further frames are added layer by layer. Depending on the system, Euro frames (ladder-type frames) or O-frames are used. Secure each connection before the next step.

Step 4: Attach diagonal braces. Diagonal braces provide the scaffold with stability against lateral displacement. They must not be omitted – even if one believes the scaffold is stable enough without them.

Step 5: Install the platform. The platform is placed on the designated supports and must sit flush and securely. Never use two overlapping boards as a substitute for a missing platform.

Step 6: Mount the guardrail. Side guardrails and intermediate guardrails are attached to the platform frame. This is legally required for fall heights of 2 meters or more.

Step 7: Attach outriggers/stabilizers (from 4 m). From a certain scaffold height, outriggers or stabilizers must be attached. The exact height depends on the manufacturer and is specified in the assembly instructions.

Step 8: Check access. Access to the platform must be safe – usually via internal ladders within the frame or a separate access ladder.

Common mistakes when assembling mobile scaffolds

• Diagonal braces omitted: The scaffold appears stable, but it is not. It will tip over under lateral load.
• Castors not locked: The scaffold rolls away when the platform is stepped on.
• Missing or incorrectly installed platform: Improvised solutions do not safely support the load.
• No guardrail from 2 meters: Legal obligation – no discretion.
• Stabilizers not installed: Mandatory from the manufacturer-specified height, not optional.
• Assembly from above instead of inside: Always ascend the scaffold from the inside, do not climb the frames from the outside.

Frequently Asked Questions

Can I assemble a mobile scaffold alone?

That depends on the system and the height. Many systems are designed for assembly by one person, provided the manufacturer's instructions are followed. For greater heights, a second person is recommended.

From what height are stabilizers mandatory?

This depends on the manufacturer. Usually from a platform height of 4 to 6 meters. The exact specification can be found in the assembly instructions.

Can I move a mobile scaffold while it is in use?

Only empty and on level ground – never with people on the platform. This is one of the most common causes of accidents.
