Introduction to Engineering Experimentation3rd EditionAhmad R. Ganji, Anthony J. Wheeler 378 solutions Supported scaffolds consist of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support. Because frame scaffolds are the most common type of supported scaffold, this eTool uses the frame module to describe requirements that are common to all supported scaffolds. Requirements specific to the other scaffold types are described only in their respective modules. Ladder JackA ladder jack scaffold is a simple device consisting of a platform resting on brackets attached to a ladder. Ladder jacks are primarily used on lighter loads because of their portability and cost-effectiveness. Mast ClimbersMast climbing supported scaffolds (Mast Climbers) carry much heavier loads than traditional scaffolding and serve to position personnel, along with necessary tools, equipment, and materials to perform work at great heights. [Also see OSHA's Overview PowerPoint.] Pole or Wood PolePosts with fixed connection points that accept runners, bearers, and diagonals, also made of wood, that can be interconnected at predetermined levels. Pump JackPlatform supported by vertical poles and movable support brackets. SpecialtyScaffold types designed for a narrow and very specific range of applications. Tube and CouplerPlatform(s) supported by tubing, erected with coupling devices connecting uprights, braces, bearers, and runners. How is a float scaffold supported quizlet?How is a float scaffold supported? By two bearers hung from an overhead support.
What is a supported scaffold?Supported scaffolds, which consist of one or more platforms supported by rigid, load- bearing members, such as poles, legs, frames, outriggers, etc. Suspended scaffolds, which are one or more platforms suspended by ropes or other non-rigid, overhead support.
How many platforms are supported on a supported scaffold?Scaffolding » Supported Scaffolds
Supported scaffolds consist of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support.
What are two types of suspended scaffolding?Scaffolding » Suspended Scaffolds. Catenary. Platform supported by two essentially horizontal and parallel ropes attached to structural members of a building. ... . Interior Hung. Platform suspended from the ceiling or roof structure by fixed-length supports. ... . Multi-point Adjustable. ... . Single-point Adjustable.. |
