Control Valve - Starts and stops the direction of fluid and controls where the fluid moves using spools. Without a control valve, forklift hydraulic pressure would be useless. Relief Valve - Protects the hydraulic system from too much pressure.This part is considered a critical safety component of hydraulic forklift hydraulic pressure. Return Line - Returns the fluid to the tank.The return line completes the forklift hydraulics cycle. The types of fluids used in hydraulic forklifts include water-based fluids, petroleum-based fluids, and synthetic fluids. Note: An important thing to remember is that forklift hydraulic systems use small forces on pistons, which exert larger forces to produce a very effective method of

Hydraulics Hydraulic presses put pressure on a small amount of liquid to create a large amount of power. With a forklift, this is lifting power.

The forklift hydraulic system pistons raise the forks and keep them lifted until the hydraulic pressure is released by the operator. In most forklifts, the tank is integrated into the frame of the vehicle.That’s what holds the forklift hydraulic fluid. In addition the hydraulic system includes: The Pump - Produces a constant flow of hydraulic fluid to supply the control valve. Most forklifts use a gear-type pump.The pump consists of a pair of rotating gears that push the fluid in the opposite direction of the rotation.

lifting, moving and shifting heavy loads. Remember that hydraulic systems are under pressure.Worn or cracked hoses can rupture, causing a hydraulic failure. Hydraulic leaks must be corrected as they indicate worn seals, pistons, or other mechanical failures. Report hydraulic deficiencies before they cause accidents.
