However, some masts can initially lift their forks without moving the inner rails. Free lift heightįor a forklift to raise cargo as high as possible, the inner rails must extend to their maximum height. Unlike maximum fork height, overall raised height helps you avoid potential obstructions when the mast is extended. Overall raised height is measured from the top of the load backrest to the ground when the mast is fully extended. This measurement lets you know if your vehicles can fit through your facility’s doorframes. The overall lowered height is measured from the ground to the top of the mast’s outer rails. This measurement lets you know if a forklift can reach the top of your warehouse storage system. It is measured from the ground to the top of the forks. The maximum fork height is the fork’s peak when fully extended. Mast featuresĮvery forklift mast has four essential features. The second is tilt cylinders, which enable the mast to lean forward and backward. The first is lift cylinders, which provide the power to raise the rails, pull the lift chains and elevate the forklift carriage. When hydraulic fluid pushes into the cylinder, pressure increases and the piston moves.įor a mast on a forklift hydraulic system, there are two types of cylinders. Hydraulic systems use this feature of liquids to transmit force. A belly flop hurts because you tried to enter the pool too quickly and with too much surface area. However, if you try to enter horizontally, like doing a belly flop, it initially feels like you landed on cement because the liquid can’t squish down (i.e., compress). For example, if you jump into a pool vertically (straight up and down), you easily reach the bottom because the liquid moves around you (kind of like a gas). They’re neither solid nor gas, but they share characteristics of both. Hydraulic cylinders are part of a forklift’s hydraulic system, which uses pressurized liquid to apply force. Hydraulic cylindersĬylinders are hollow tubes that are open at one end so fluid can enter with a movable piston at the other end. As the inner rails rise, the chair wheel turns-operating like a pulley-causing the chains to rise also and lift the carriage. The other end of the chains is bolted to the inner rails. The length then travels around a chain wheel. One end of the mast chains is anchored to the carriage. When the inner rails begin to move, it’s the mast chains that lift the forklift carriage. Instead, it attaches to a mount located between the mast’s rails. The forklift carriage is not actually part of the mast. Forklift carriageĮvery component used to secure a load connects to the forklift carriage, including the forks, load backrest and any accessories. Every forklift has two stationary outer rails and at least one set of inner rails (or channels) that move up and down. The rails are the most noticeable mast of forklift feature because they form the structure, or frame, of the mast. While the job of a forklift mast-raising and lowering cargo-is relatively straightforward, successfully achieving the task requires several complex components working in unison. ![]() While the forks support the cargo, it’s the mast that does all the heavy lifting. When searching for the right lift truck for your operation, the forklift mast is an essential consideration.Ī forklift mast, also known as an upright, is the vertical component that controls the raising, lowering and tilting of a load. ![]()
