Lift Truck Masts


 SMC Euroclamp offer a range of masts from our partner company ATIB. The truck masts are made to replace the current mast fitted to the truck to offer for example the ability to telescope out to reach greater heights. When choosing a forklift mast, there are a few factors to consider in addition to type: the lowered and extended height, lift height, and freelift.

The mast consists of a fork and an elevation mechanism, associated with the lift truck’s hydraulic assembly. Two systems of classification have arisen to describe a forklift truck’s mast in detail. An operating manual may classify the mast either by the lift mechanism or by the number of mast “sections”. Regardless of the terminology, it’s important to know the difference in forklift mast types when choosing the right forklift mast for your facility.

Mast Types

Simplex – A single stage mast has only one channel, and therefore a limited lifting height. Single stage masts have zero freelift and are best for outdoor applications or environments where overhead clearance is not an issue.

Duplex – A two stage mast, also known as a duplex, has two sections. The outer stage does not move and gives the option for freelift. The inner mast section raises up to elevate the carriage and forks. A two stage mast offers great visibility and is ideal for moving loads in trailers.


Triplex – A three stage mast, or triplex, is the most versatile forklift mast and also the most popular. The outer rails allow for free lift, and the two inner sections can lift loads higher than a two stage. This mast type is a good choice for general warehouse applications.

Quad – A quad, or four stage mast is designed for very high stacking. Quad masts allow for a shorter collapsed height when compared to a three stage with equivalent MFH (maximum fork height).
