Scaffolding Parts

Here are all the parts used to make scaffolds: 

• Standards.This is a framework that consists of vertical members supported on the ground, on drums, or embedded into the ground.
• Ledgers. Tubes with a case wedge fixing device on their end that are positioned horizontally between two standards, defining the length of the scaffold bay.
• Braces. Braces are fixed diagonally to the standards.
• Putlogs. A putlog connects the wall being worked on and the ledger. A putlog hole is made in the side of a building to receive a putlog. 
• Transoms. A transom is a type of ledger putlog that is supported by both ledgers.
• Bridle. Bridles support one end of the putlog and are used to bridge an opening in a wall.
• Boarding. During the working process, boarders serve as horizontal platforms for supporting workmen and materials.
• Guard rail. A rail set up at the same level as a ledger.
• Toeboard. A parallel set of boards, supported on putlogs, which provides protection at the working platform level.
• Ladder scaffolding. Scaffolding ladders allow workers to ascend and descend the constructed scaffold easily.
• Scaffolding wheels. Wheels at the bottom of the scaffold that allow easy movement of the scaffold from one place to another.
