How does a forklift mast work?
The carriage is actuated by the hydraulic piston in the middle of the mast. By pulling the mast lever on the cowl it raises the load by actuating that piston, thus lifting the forks and your load. All masts lift by hydraulic displacement and lower by the force of gravity.
How do you manage a forklift?
Ensure both forks are as far under the load as possible before lifting. Drive with the load as low as safely possible. Pay attention to posted speed limits and warning signs. Always look in the direction you’re traveling; if a load blocks the view ahead, travel in reverse.
How does a hydraulic mast work?
The mast jack system consists of a hydraulic cylinder located inside the mast. The cylinder piston moves down vertically through the heel of the mast to a steel plate in the boat’s T-base, thereby lifting the mast and increasing the tension.
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)
What is the most common forklift hazard?

How can you control forklift speed in your workplace?
They can be controlled by GPS/RFID zones to give different speed limits in open yards vs tight racking or areas near pedestrian activity. This is called geofencing. Speed limiters can also be used to control throttle response, something that can improve tyre wear.
When traveling make sure the mast is?
When traveling with a load, always make sure to tilt the mast of the forklift backward so that the load will firmly place against the backrest to make it more secure during transport.
What is 3-stage mast in forklift?
3-Stage – 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.
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.
A forklift mast lifts by hydraulic displacement and lowers using the force of gravity. The mast has multiple sections that work together to lift. Nested rails allow the mast to extend and lower.
How do I choose the best forklift mast?
One factor to consider when choosing a forklift mast is free lift, especially in a location with low overhead clearance. Free lift is how high a forklift operator can raise the forks without the mast height changing.
What factors affect forklift mast selection?
Another factor that affects forklift mast selection is the lowered height, also known as the collapsed height. The lowered height is the distance from the floor to the top of the mast when the mast is lowered. The lowered height is especially important to consider if your forklift will be traveling through confined spaces like doorways.
What is a two-stage mast forklift?
The two-stage mast, also known as a duplex mast, has free lift available and is often used for stacking and double stacking for indoor applications with limited overhead. Two-stage mast forklifts have good visibility since there aren’t as many mast sections impeding the driver’s view.
