Abstract

See full text

A scissor lift (100) for use in a stage assembly includes a base portion (110) configured to be supported on a floor or other support surface and a top portion (120) configured to support a platform. A scissor arm assembly (130) connects the base portion (110) and the top portion, and a rigid chain lifting system (150) comprising a rigid chain (151) connecting the base portion (110) and the top portion (120). Extension and retraction of the rigid chain (151) causes the top portion (120) to rise and fall with respect to the base portion (110). The use of a rigid chain lifting system (150) means that the scissors (130) are provided for guidance rather than applying load. The scissor lift (100) can be used in conjunction with one or more passive scissors (200), couplable to the scissor lift (100).
