1. Scaffold height ratio - indoor
Indoors, the maximum height of the platform is 3.5 times its width. For example, the width of the platform is 1.35 meters and its height cannot be higher than 4.7 meters.
2. Scaffold height ratio - no wind outside
When there is no wind outside, the maximum height of the platform is 3 times its width. For example, the width of the platform is 1.35 meters, and the height cannot be higher than 4.1 meters.
Note: Outdoor scaffolding should be strictly limited to its height, not more than 3 times the width.
3. Externally supported device
Indoors, the height of the table is 3.5 times its width. For example, the standard external support of the device ST1 increases its width to 3.47 meters, so its height can be increased up to 12.15 meters.
4. Externally supported device
Outdoors, the height of the table is three times its width. For example, the large outer support of the device ST2 increases its width to 5.83 meters, so its height can be increased up to 17.5 meters.
5. Impact of external factors
The biggest influencing factors: lateral force, wind force, external force;
Ground conditions: obstacles;
The role of external force.
When a construction worker drills a hole in a wall using a construction tool such as an electric drill, the generated pressure generates an opposite reaction force. Therefore, scaffolding should reduce its use height accordingly.
Please pay attention to the ground conditions during construction. First check the ground and related locations:
● The ground must be flat
● No ladder (except special requirements)
● No gap
● Clean up all rubbish on the ground
● Pay attention to higher dangerous objects
● ceiling height
● Hanging objects
● Wires, etc.
