Forklifts and Lift Gates
All of our Single Post, 2 Post, and 4 Post Lifts* require a forklift (or similar) to unload. Tire Changers and Balancers and other small items allow for a lift gate service (At no additional charge) Lift gate service will lower your order to street level. How do I know if a forklift is required? See the drop down options that show when you're attempting to place an order.
