This model lifts up to 6,000 pounds. This lift is a quad mast (four stages) forklift, that can extend the lifting height up to 21′. Load capacity will vary based on height. A quad mast is perfect for areas with very low height restrictions, such as rail or truck container doors, because they have the shortest lowering height for its lift. It also has a mast so you can lift higher once you’ve removed the cargo from the truck.
