What Is A Light Duty Scaffold?

What is a scaffold platform?

Supported scaffolds are platforms supported by.

legs, outrigger beams, brackets, poles, uprights, posts, frames, or similar rigid support..

What is a scaffold standard?

The key elements of the scaffolding are the standard, ledger and transoms. The standards, also called uprights, are the vertical tubes that transfer the entire weight of the structure to the ground where they rest on a square base plate to spread the load.

Which scaffolding would hold more weight?

Weight Capacity These types of scaffolds are best used when weight is spread out along the platform. A light-duty scaffold can hold about 25 pounds per square foot, a medium-duty scaffold can carry 50 pounds per square foot, and a heavy-duty one will hold 75 pounds per square foot.

What are the 3 load ratings of scaffolds?

Get a Scaffold Board Quote OHSA designates three different categories for load bearing calculations on scaffold boards. They are: Light Duty – 25 pounds per square foot. Medium Duty – 50 pounds per square foot.

Can I build my own scaffolding?

Build scaffolding yourself so that you can work safely and comfortably on the upper portions of your home exterior. To safely work on your house, use scaffolding that you can build yourself. Nail a three-foot and a five-foot length of 2 x 4 at right angles. … A double 2 x 6 will support your scaffold from the ground.

What is the ratio of scaffolding?

4:1Working Out Height Capacity of Scaffolding The load capacity of scaffolding is determined by a height to base ratio of 4:1, Meaning the scaffold can be up to four times the minimal base width.

What is heavy duty scaffold?

Scaffold working platforms are generally rated as light, medium or heavy duty: Light Duty – up to 225 kg per platform per bay including a concentrated load of 120 kg. … Heavy Duty – up to 675 kg per platform per bay including a concentrated load of 200 kg. Platforms should be at least 1000 mm wide.

What are the 3 types of scaffolds?

Types of Scaffolding used in Construction:Single Scaffolding.Double Scaffolding.Cantilever Scaffolding.Suspended Scaffolding.Trestle Scaffolding.Steel Scaffolding.Patented Scaffolding.

How much weight can a scaffold board take?

150 KGThe maximum safe working load of a scaffold board is 150 KG evenly spaced. The total weight of the user and tools must not exceed this. When moving to a new site, carry the equipment with care.

What is height to base ratio?

In general, the 1: 3 ratio is applied as a starting point for consideration. The minimum base size of the structure is measured and multiplied by three to obtain the safe maximum height of the structure.

What is medium duty scaffold?

Medium Duty Scaffolding refers to a Safe Working Load (SWL) of 450Kg per bay or tower. This equates to four average male workers with tools and equipment.

How high can you build a scaffold?

The 4-foot scaffold becomes 4 ft. by 6.167 ft.; the 6-foot scaffold becomes 6 ft. by 6.417 ft.; the 7-foot scaffold becomes 7 ft. by 7.333 ft….OSHA.Model (not using outriggers)Total height* at which restraint is required4-foot (26 inches wide)over 8.668 feet6-foot (29 inches wide)over 9.668 feet2 more rows

How is SWL calculated?

Once you know the diameter of the rope, you can apply it to the formula, which is SWL = D2 x 8. D represents the diameter of the rope in inches. If you’re working with a 1.5-inch diameter cable, for example, then the formula would be SWL = 1.52 x 8 or SWL = 2.25 x 8.

What is hanging scaffold?

A hanging scaffold is a scaffold hung from a structure that is static in the vertical plane; it cannot be raised or lowered by any means. Hanging scaffolds can be hung from tubes, wire ropes, ropes or chains etc. Hanging scaffolds are classified as a special duty scaffold and should be designed and notified as such.

What is the maximum gap between scaffold and structure?

The gap between a working platform and the face of the structure must be as small as possible, except in the case where it is necessary for a person to sit on the edge of the platform to work, when the gap should not exceed 300 millimetres.

Can I tie off to a scaffold?

Question 3: Do the OSHA standards prohibit tying off to a scaffold? Answer: No. It is OSHA’s position that scaffolding can function as a suitable anchorage for fall arrest systems when the scaffolding section so used is erected and braced such that the criteria of §1926.502(d)(15) are met.

How high can you build a mobile scaffold?

12 metresA mobile scaffold can only be built to a maximum height of 12 metres.
