Just like a 2-door car can also be described as a coupe, the most common forklift mast types have interchangeable names. Before you buy or rent a forklift, it’s important to know the various names for different types of forklift masts.

Forklift Mast Types: Know Before You Buy
Before choosing a forklift mast, you’ll need to answer some key questions:
- Does the forklift need to pass through a space with height restrictions (such as a garage door)?
- Will the forklift operate in a container, truck trailer or rail car?
- How tall is the highest shelf the forklift will need to reach?
- What is the weight of the heaviest load the forklift will transport?
You can collect this data yourself or schedule a free site survey with one of our friendly forklift consultants.
Simplex, 2-Stage, 3-Stage and Quad Forklift Masts
There are four common types of forklift masts (also known as uprights).
- 2-stage (V and FV)
- 3-stage (FSV)
- 4-stage (QFV)
What separates one mast type from another is the number of stages and the mast’s freelift.
Stage = a section of the forklift mast. You can think of stages like railroad tracks. The more you have, the farther the mast can go.
Freelift = how high the forks can lift a load before the mast starts to extend.
- A mast with zero freelift means the upright rises along with the forks. If you have height restrictions, a zero freelift mast might not be a good choice.
- With a full freelift mast, the forks can be raised to the top of the mast’s inner channel without the forklift getting any taller.
Simplex (V) Single-Stage Mast
A single-stage forklift mast, often called a simplex mast, has zero free lift. Forklifts using this type of mast are typically used outdoors or in applications where overhead clearance is not a concern.
Because a “V” forklift mast has only one stage, its maximum lifting height (also known as MFH) is limited. If you need to raise loads up to 157" (13 feet), choose a 2-stage mast.
2-Stage Forklift Mast (FV and V)
Also known as a duplex or double, the 2-stage forklift mast comes in three flavors.
- FV (with freelift)
- V (without freelift)
- Trucker’s mast (shortened 2-stage without freelift)
In case you’re wondering, “What do V and FV stand for?” A “V” forklift mast means view and “FV” means freelift view.
The FV Mast is the second most popular forklift mast with customers here in northern California. You get a greater maximum lift height than with a simplex (because there are two stages) and the ability to operate in spaces with height restrictions, such as inside trailers. Most FV forklift masts can lift a load 50” before the mast extends. This type of forklift mast can also be called an FFL or HiLo mast.
The Trucker's mast is designed for stacking inside a trailer. It has a short mast and the maximum lift height is about 60" (5 feet).

FSV 3-Stage Forklift Mast
Also known as a triplex, triple or TSU forklift mast, the 3-stage forklift mast is the most popular forklift mast here in northern California, especially with warehouse operations.
Toyota offers two types of 3-stage forklift masts, one with a central lift cylinder and another with side cylinders for a better forward view (see image above). The maximum fork height tops out around 131-189” depending on the forklift.
QSV 4-Stage Forklift Mast
The freelift on a quad mast forklift is similar to an FSV, but it can lift loads even higher – up to 240” (20 feet). There are two drawbacks to this type of mast.
- Because there are four nested rails, a quad mast forklift has limited forward visibility compared to a duplex or side-cylinder 3-stage forklift mast.
- The very high lifting height also limits capacity. For example, the capacity on a 5000 lb. forklift is almost cut in half when using a QSV mast.
