#Single stage forklift mast free
Its free lift and greater heights provided by three stages make for a great lift for stacking in general warehouse applications. Three Stage – The three-stage mast is the most common and versatile forklift mast available. The primary cylinder also raises the carriage at a 2-to-1 ratio but raises the carriage to the top of the inner rails before the hydraulic fluid is rerouted to the side-mounted secondary cylinders for direct rail lift.

This upright resembles the standard upright and works in the same way, except a primary, center-mounted cylinder provides full free lift. The duplex upright is a two-stage assembly with a full free lift. They provide excellent visibility and are ideal for use in trailers and boxcars. These are typically used for stacking and double stacking for indoor applications with limited overhead clearance. Two-Stage: The two-stage mast is more common and has a free lift available. Single-stage mast forklift 2 stage mast forklift The chain raises the carriage at a rate of two inches for every inch of cylinder rod extension. This upright uses two side-mounted lift cylinders to provide direct lift to the inner rails and indirect chain lift to the carriage/fork assembly. The standard upright is a two-stage assembly with two rails, one stationary and one movable inner rail. This type of mast is frequently seen in outdoor applications where overhead clearance is not a concern, due to the lack of height clearance restrictions.
Free lift (the ability to lift the load and forks without moving the mast channels) is not available.ĭue to this limitation, the mast must extend higher than other mast options in order to stack loads. Single Stage: The single-stage mast has one channel with a limited lifting height. Forklift Mast Types Single-stage mast forklift Below defined the four basic types of uprights and masts: standard, duplex, triple stage, and quad.

This feature is imperative for double stacking in a trailer.Īnother feature that is an option but is now considered essential to most users is “side shift”. From a simple direct lift to multiple channel staging, each mast type has features that enhance performance or extend the application range of the lift truck.įree lift is the distance that the carriage will raise prior to the inner channel extending. Pulling the mast lever on the cowl raises the load by actuating that piston, thus lifting the forks and your load.Īll masts lift by hydraulic displacement and lower by the force of gravity. The carriage is actuated by the hydraulic piston in the middle of the mast. The channels are similar in appearance to I-Beams.Īttached to the mast is the carriage.
Most masts are ‘three-stage’ meaning there are three channels on each side.
Forklift Mast Types: Also referred to as an ‘Upright’, the mast is the vertical assembly on the front of the forklift that does the work of raising, lowering, and tilting the load.
