How do Mechanical VRC Lifts compare to Hydraulic?

Major Points
CIP Mechanical
Fluids Will never leak. Will eventually leak. Slight seepage is considered normal. This is an environmental issue.
Lifting Force Driven by an electric brake motor cyclo-reducer which lifts the platform with cables or chains. Electric motor drive the hydraulic pump, forcing fluid thru a system of control valves, flexible hoses, and cylinders. Higher applications must also add cables or chains, increasing complexity and maintenance.
Cycle Limits 100% duty cycle. 10 cycle per hour average.
Travel Steady & smooth. Precise positioning with limit switches. High oil temperature which could lead to the lift to shutdown, can cause jerky and inconsistent movement. Precise intermediate stops and leveling not possible due to hydraulic drift.
Noise Very quiet. Higher noise level. High pitched whine.
Maintenance The cable will stretch over time, but that is all that will have to be adjusted or replaced. As the unit ages, the hydraulic pump, cylinders, chain, and hydraulic oil will have to be replaced for the lift to continue to move the rated capacity.


The Choice: By far, the mechanical lift is the better choice for quality, longevity and less than $500 annually in maintenance costs.
