Lift

A stage assembly comprising:

• a scissor lift for use in a stage assembly;
• the scissor lift comprising:
• a base portion configured to be supported on a floor or other support surface;
• a top portion configured to support a platform;
• a scissor arm assembly connecting the base portion and the top portion;
• a rigid chain lifting system comprising a plurality of rigid chains connecting the base portion and the top portion, wherein the scissor lift is configured such that extension and retraction of the plurality of rigid chains causes the top portion to rise and fall with respect to the base portion;
• wherein the scissor arm assembly comprises two scissor arm subassemblies, each scissor arm subassembly comprising at least one pair of crossed arms connected at a pivot point to form a scissor, wherein uppermost arms of each scissor arm subassembly are being pivotally attached to the top portion by at least two upper support arms, and
• lowermost arms of each scissor arm subassembly are being pivotally attached to the base portion by at least two lower support arms, and wherein the base portion of the scissor lift comprising at least one track arranged and disposed to receive a wheel;
• a plurality of bracing plates extending between the two scissor arm subassemblies, wherein the plurality of bracing plates are configured to move to a nested configuration when the rigid chain is retracted;
• each bracing plate of the plurality of the bracing plates comprises an upper plate, angled side plates extending obliquely downward from the upper plate toward the cross arms, and flanges connecting the side plates to the cross arms.
