Forklift Mast Types

What type of mast do you need for your forklift?

This may be a question posed to you during your next forklift purchase. Understanding the types of masts available and what each can do is helpful for selection. Below ProLift has defined the four basic types of uprights and masts: standard, duplex, triple stage and quad.

4 Types of Forklift Masts

Standard Upright (Simplex, V Mast)

The standard upright is a two-stage assembly with two rails, one stationary and one movable inner rail. 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 chain raises the carriage at a rate of two inches for every inch of cylinder rod extension.

Duplex Upright (Full Free Lift, FFL, Hi-Lo, FV Mast)

The duplex upright is a two-stage assembly with full free lift. This upright resembles the standard upright and works in the same way, except a primary, center-mounted cylinder provides full free lift. 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 hydraulic fluid is rerouted to the side-mounted secondary cylinders for direct rail lift.

Triple Stage Upright (Triplex, Triple, TSU, FSV Mast)

The triple stage upright uses three sets of rails, two movable rails and one stationary rail for three stage lift with full free lift. The same principles of operation apply in triple-stage lift as the hi-lo model but with an extra stage of lift. The primary cylinder provides the full free lift of the carriage and forks. The secondary lift cylinders are attached to the intermediate rails. When these cylinders begin lift, they lift the intermediate rails directly while the chains pull the inner set of rails along with the carriage/fork assembly.

Quad Upright (QFV Mast)

The quad upright uses four sets of rails and an added set of chains to provide four stages of lift with full free lift. Quad uprights work basically in the same way as triple stage uprights except in that a second set of chains and pulleys operated by the secondary lift cylinders provide the fourth stage of lift.

10 Frequently Asked Questions About Vertical Goods Lifts

This post aims to provide answers to the 10 most frequently asked questions about installing, using and maintaining goods lifts. We hope you find this post helpful. If you have further questions, please feel free to contact us.

Q1: If I decide to get a goods lift how long will I have to wait to install it?

A: Your new goods lift will have a lead time for the manufacture of your bespoke requirements. Once delivered, the lift can be installed well in just a few days. You may need builders work before installation depending on where your lift is positioned.

Q2: Do I need to build a lift shaft?

A: It depends on the installation site and safety requirements. Our vertical goods lifts can be supplied structure-supported so there would only be a need to build an enclosure that is not load bearing. The enclosure guards the machinery &#; the working parts of the lift.

Q3: Can I travel in the lift?

A: If you need to travel with your goods, you will require an attendant controlled lift with controls inside the lift.

Q4: I&#;m concerned I have limited space. How do the doors open on a goods lift?

A: Goods lifts come with a choice of door configurations. At MORN, we offer hinged doors to give the largest opening, or concertina doors that fold back either outside or within the lift apperture to save space in front of the lift.

Q5: I have reduced space at the upper floor of my building. Is this a problem?

A: There are reduced headroom goods lifts for most situations and reduced pit models too.

Q6: How do you recommend I load the lift?

A: Ideally spread your load evenly from the centre of the lift car outwards and then upwards. An even load means the cargo lift will be operated more efficiently and your goods are secure. A pump-truck or sack-truck may assist the loading.

Q7: What happens if my lift breaks down?

A: New lift equipment will be covered by a 5-year guarantee on the main structure. Our technical team is also ready to offer online and on-site door-to-door service to each user &#; so a MORN engineer is never far away.

Q8: I need access to a mezzanine level. Can this be provided via a lift?

A: You can certainly use a lift to access a mezzanine. You can install a goods-only or attendant-controlled lift depending on the nature of your goods and the function of the mezzanine level. Our structure- supported goods lift platforms are ideal and customizable.

Q9: Do goods lifts have similar operating controls to like passenger lifts?

A: The operating switches for goods-only lifts are on the landing entrances of the lift. You can send or call the lift from each landing. If you need to travel with goods then there will be additional constant-pressure operating buttons inside the lift too.

Q10: I have low flight of stairs in my premises that can be avoided via a ramp but still makes moving pallets of goods so physically demanding. Is there a product that can provide a solution?

A: Platform goods lifts can be installed to overcome a change in levels of up to 1.5 meters. This is an investment that saves time, money and potential injury to staff as well as improving customer service.
