Abstract
The elevating lift includes a stabilizer base with extendable legs to provide minimum to maximum stability during use and transport. A lift system is fixed to the stabilizer base, and a platform assembly is mounted to the top of the base to be selectively raised or lowered by the lift system. The lift system utilizes a plurality of telescoping cage assemblies interconnected to extend or retract relative to each other. A drive assembly with an extendable lift mast is mounted to the stabilizer base to act on the cage assemblies to raise or lower the same. A drive train coupled to the telescoping cage assemblies enables relative extension and retraction of the cage assemblies. An adjustable guardrail is mounted to a platform of the platform assembly to provide safety for the user.
