Comparison of aerial work platforms and scaffolding in the ascending industry

Guide: Using scaffolding or aerial work platform, this is a proposition that has been difficult to determine. Only the benevolent sees the wise and sees wisdom. So what is scaffolding? What is an aerial work platform? What is the difference between the two? What should I pay attention to when using?

First, about scaffolding

Scaffolding was used most in the industry a long time ago. For example, for paint, new construction, refurbishment, routine maintenance and demolition projects. Although there are many types of scaffolding, scaffolding is generally used without a substitute. Scaffolding is defined abroad as “temporary elevated platform (support or suspension) and its supporting structure (including anchoring points) to support employees or materials or both.”

The rules for scaffolding generally vary depending on whether it is supported or suspended. The fall protection trigger height of workers supporting the scaffolding is about 3 meters, and the workers on the suspended scaffolding need to be tied to the designated anchor points. For supporting scaffolding, passive fall protection, such as guardrails, is required. It is important to ensure that the guardrail meets national safety standards, as the cited violations usually include improper installation and/or improper use of the guardrail. For example, the use of cross braces as guard rails is unacceptable. However, depending on the distance between the cross braces, the cross bracing may be the top rail or the middle rail of the guard rail system.

Scaffolding and aerial work platforms

Second, on the aerial work platform

The most widely used option in the industry today is the aerial work platform. For example, they are used for maintenance or repair of buildings and short-term construction projects. Aerial work platforms include boom lifts (boom lifts and truck lifts), scissor lifts, spider lifts and mast lifts. An aerial work platform is defined as a powered or manual propulsion device supported by a ground structure.

The rules for aerial work platforms generally vary depending on whether they extend beyond the base. For example, the work platform on the articulated lift extends above the base, but the work platform on the scissor lift extends only vertically above the base. Active landing protection, such as full body harnesses and shock cords, is required if the work platform extends farther than the base. If the work platform extends directly perpendicular to the base, passive fall protection, such as guardrails, is required.

So which climber is the best, aerial work platform or scaffolding? This question is difficult to answer. While aerial work platforms and scaffolding are substitutes for ladders, aerial work platforms and scaffolding do have different uses. Therefore, it is difficult to give a specific case of when to use a high-altitude platform on a scaffold, and vice versa. However, some general conditions do apply.

Aerial work platform instead of scaffolding

Third, use the aerial work platform instead of scaffolding under the following circumstances:

1. When a large work area is needed to complete the project

2. When the project takes a long time to complete

3. When the scaffolding cannot be placed close enough to safely complete the project (such as uneven surfaces or obstacles). )

4. When a small work area is sufficient to complete the project

5. When the project can be completed in a short time

Fourth, important considerations to remember when using scaffolding

1. Evaluate any risk of falling before assembling the scaffolding.

2. Place the feet of the scaffolding on a solid surface.

3. Scaffolding must be assembled under the direct supervision of qualified personnel.

4. All sides of the scaffold must have passive fall protection, such as guardrails.

5. If anyone needs to pass under the scaffold, the worker must install a barrier to prevent the object from falling.

5. Important considerations to remember when using aerial work platforms

Use the aerial work platform to keep the upper body in the working platform

1. Evaluate any risk of falling before using the aerial work platform.

2. Keep your upper body in the working platform.

3. No guardrails, ladders or other devices that extend the working position out of the work platform.

4. Only the specified anchor point can be used when knotting. Check that the manufacturer of the aerial work platform provides an approved anchor point that can withstand the force of the fall event.

5. Evaluate whether a fall may occur before connecting to the anchor point.

6. Use the shortest possible rope to complete the project.

7. Do not exceed the rated capacity of the aerial work platform manufacturer, including the weight height.
