Dump truck cylinders are one of the key components of any dump truck. If you own a business that relies on several dump trucks, you know how important it is that these cylinders are operational and that they can effectively contribute to the repeated up and down motion your truck has to engage in several times a day.
Also known as telescopic hydraulic cylinders or hoist cylinders, dump truck cylinders are responsible for lifting the bed of the dump truck to unload its contents. In most dump trucks, these multi-stage cylinders extend in different sections, just like a telescope. They allow for a long stroke in a compact retracted size to occur, which is perfect for lifting a larger truck bed high into the air.
When dump truck cylinders engage, hydraulic fluid is pumped into the cylinder by the hydraulic system. This fluid pressure pushes each part of the cylinder out, starting with the largest and working its way up to the top. As the different parts extend, the dump bed moves upward from its hinge point. After the bed is raised enough, gravity helps the material slide out of the bed. When the bed needs to go back down, the hydraulic pressure is released or reversed, and the cylinder then retracts in stages, so the bed goes back down smoothly.
