Mechanical 4 Post Freightlifts are designed to stop at multiple positions with more precise control of their stop-start movements. They are mechanically operated by means of a brake motor and gear reducer with a common drive shaft. Raising and lowering of the carriage platform is accomplished with heavy-duty roller chain. Our standard models range from 120 to 240 inches with load capacities from 6,000 to 20,000 pounds.  Through our custom engineering capabilities, we have designed Mechanical 4 Post freight lifts to access heights up to 100 feet.
