Abstract
An ambulatory power lift including a base and a movable lifting platform connected by a scissor lever assembly. Hydraulic power cylinders expand said scissor assembly in a manner which applies a substantially vertical lifting force to said platform. A modular power unit directs hydraulic fluid to said cylinders and allows the remote control of the lifting operation. A retractable bridge assembly on one end of the platform automatically raises as said lift is lowered, and a retractable wheel assembly allows the lift to be selectively transported in a lowered condition. A retractable guardrail closes at least one end of the lift platform. Safety means are also provided to prevent tampering with said power unit and to prevent entrapment between the platform and base.
