What are the 3 common mast types?
Single-Stage Vs. There are three common types: Single Stage (simplex mast) 2-Stage (duplex mast) 3-Stage (triplex mast)
Do forklifts use chains?
Each forklift uses chains coupled with hydraulic pressure in order to move the forks up and down. As a result, your forklift’s chains carry the load of thousands of pounds each day.
When should forklift chains be replaced?

How Long Do Forklift Chains Last? In a single-shift operation, where lifting is done on an even surface, a forklift’s chains can last three to five years. But it’s still important to inspect the chains on a newer forklift as environmental factors such as dust, rain and industrial chemicals cause chains to break down.
Why is it important to check the lifting chains on a forklift?
When it comes to forklift operation, forks and lift chains are put under heavy stress for every load. This means that they are prone to wearing down over time. Heavily worn chains or forks can pose a serious safety risk and affect the performance of your machine.

What is 2 stage mast forklift?
2-Stage – 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.
What is a TF mast?
The forklift’s mast, or upright, is the portion of the forklift that lifts, lowers, and positions the loads manipulated by the forks. Each type of mast presents its own set of advantages for different applications depending on their height and stacking requirements.
What is a Hi Lo mast?
Two-Stage Mast with free lift – Duplex Hi-Lo This mast combines high lift heights with a low mast height. Suitable for stacking applications in halls with limited ceiling heights, on covered lorries and places where the truck must pass through doorways with low clearance.
What are 6 defects that will condemn a lifting chain?
