Anyone who has ever operated a forklift knows how important the hydraulic system is. This system is what enables forklifts to lift heavy loads and maneuver in tight spaces. Understanding how the hydraulic system works can help improve your forklift skills and safety while also promoting efficient and effective work. Having an awareness of forklift hydraulic cylinder can also assist when it comes to identifying potential forklift issues.
Forklifts use hydraulic systems to produce linear movement and force by using pressurized fluid. The fluid, usually hydraulic oil, is contained within a reservoir tank that feeds into the hydraulic pump. The pump then pushes hydraulic fluid through a series of hoses to the forklift lift cylinders. This fluid pressure generates mechanical force that lifts heavy loads and enables the forklift to tilt.
There are at least two lift cylinders in every forklift, and they can be either piston or ram type. Each cylinder accepts a set amount of hydraulic fluid flow or gallons per minute (GPM). Control valves are then used to direct the fluid flow between the cylinder and the forklift mast to lift and lower loads. These hydraulic cylinders are what allow forklifts to carry massively hefty loads that would be impossible for human operators to lift manually.
A forklift hydraulic cylinder works by Forklift hydraulic cylinder using Pascal’s Law to create large amounts of force from relatively low hydraulic pressure. The cylinder’s internal volume allows the piston to move, but because of the laws of physics it cannot move in the opposite direction, and thus only produces linear motion and force. When the forklift is in the lift position, a control valve directs hydraulic fluid to the cylinder and rod, and it pushes up the mast and load until it reaches its maximum height. The forklift is then able to raise and keep the load elevated until it is needed to be lowered or if the operator releases the pressure.
When the control valve is switched to tilting, the forklift’s two tilt cylinders engage with the left and right stationary rails of the upright frame to tilt forward and backward. The forklift’s tilt cylinders can be either piston or ram type and are connected to the forklift mast via a connecting rod. A flow control valve is used to regulate the amount of hydraulic fluid flow that goes to each cylinder, allowing for precise tilting movement.
A relief valve keeps hydraulic pressure from building up to dangerous levels. This prevents leaking connections, ruptured hoses and other safety issues that can occur when too much pressure is applied.
A forklift’s hydraulic system is complex, but it is simple enough for most people to understand. If you’re concerned about your forklift hydraulics, consult with an experienced service technician and learn more about how the system functions. The more you know about the hydraulic system, the easier it is to troubleshoot problems and find the best forklift repair company to fix your equipment.
