Loading Capicity Requirements for Scaffoldings

Scaffoldings must have sufficient bearing force but can not be damaged by its self loading capacity and at least 4 times of calculated force. For safety handrails, hanging cables and wooden structures, they will be applied separately:

Grades of loading forces: loading forces are classified as follows:

•  Heavy loading force: applied for scaffoldings with working load of 375  kg/m2 for building bricks, stones, and materials placed on the scaffoldings.
• Medium loading force: applied for scaffoldings with working load of 250 kg/m2 for people and mortars
• Light loading force: a plied for scaffoldings with working load of 125 kg/m2  for people and working equipment.

Requirements on loading force of peple:  Design loading force for scaffoldings is calculated basically on one or more than one persons with the weight of 75 kg and 25 kg of working equipment for each person. Each working platform must have capacity to carry at least one person as below regulation:

• Working platform used for one person is sufficiently designed and installed for supporting 100kg weight place in the middle of working platform.

• Working platform used for two people is sufficiently designed and installed for supporting working load of 200 kg, of which 100kg is placed 0.45m from the left side and the rest is placed 0.45m from the right side of the center line of working platform.

• Working platform used for 3 people is sufficiently designed and installed for supporting 300 kg, of which 100 kg is placed 0.45m from the left side, 100 kg in the middle and the rest is placed 0.45m from the right side of the center line of working platform.
