Loading Capicity Requirements for Scaffoldings

Scaffoldings must have sufficient bearing force but can not be damaged by its self loadingcapacity 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 workingequipment 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 300kg, 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.
