• There are three basic types of scaffolds:
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.
• Other scaffolds, principally man lifts,
personnel hoists, etc., which are sometimes
thought of as vehicles or machinery, but can
be regarded as another type of supported
