Forklift Masts 101: Everything You Need to Know Before You Buy
Before buying the forklift, it is important to understand the forklift masts and some of the key factors such as lift capacity, lift height and restrictions, visibility and compatibility. The widely used masts are simplex, duplex, triplex, and quad masts, each of which varies in lift height and capabilities. It is important to select the one that suits your operating requirements, environment, and lifting needs. For example, if you’re operating in a congested space, you need to choose a free-lift mast.
In this blog, let’s discuss the factors to consider when choosing the right forklift and types of forklift masts.
What are the factors to consider when choosing the forklift masts?
Some of the factors to consider before choosing the forklift masts are:
Height: Find the maximum height required for your industrial applications.
Lift Capacity: Determine the weight that you need to lift; taller masts usually have low lifting capabilities.
Height Capacity: If you’re stacking the items in a low-ceiling and confined space, you need a free-lift mast that allows you to raise the forks without increasing the overall height of the mast.
Machine requirements: Make sure you choose the mast that is compatible with the forklift by selecting the right type, brand, and serial number.
Types of Mast
Below are the different types of mast available for forklifts for different applications:
Simplex (single-stage) Mast:
It is the most economical and simplest model with a single channel. Simplex mast is capable of extending vertically where overhead clearance is not a concern, and it is commonly used to lower lift heights.
Duplex or two-stage) Mast
The duplex is featured with 2 sets of rails that are capable of providing free lifts to allow the loads to rise before extending the mast. Duplex is suitable for medium-height work environments and spaces, and it is typically used for moderate stacking.
Triplex or three-stage Mast
It is the most commonly used mast type with 3 sets of rails, providing one full free lift. It is versatile, making it suitable for different applications such as loading or unloading vehicles and reaching bigger heights.
Quad or four-stage mast
It has four sets of rails suitable for high-rise storage spaces and capable of high stacking, but to operate it effectively, it may require professional training for operators.

Points to ponder
All the above masts cannot be used interchangeably in your forklift. Before buying the desired forklift, verify its compatibility and performance, and ensure it is suitable for your industrial application.
