Suspended Scaffolds Multi-point Adjustable
A multi-point adjustable scaffold consists of a platform (or platforms) suspended by more than two ropes from overhead supports and equipped with means to raise and lower the platform(s) to desired work levels. An example of this type of scaffold is a chimney hoist, used in chimney-cleaning operations.
NOTE: The requirements on this page are specific to multi-point adjustable scaffolds only. For requirements that apply to all types of suspended scaffolds, please refer to the Two-point (swing stage) module of this eTool.
