The hydraulic system is a power transmission system that uses pressurized fluid to generate
controlled force and movement, It's the "muscle" of the forklift, responsible for lifting loads, tilting the mast,
and sometimes operating attachments.
Main Functions:
Lifting the Load: Raising and lowering the forks and carriage. ·
Tilting the Mast: Moving the mast forward or backward for load stability during travel and placement.
Operating Attachments: Powering auxiliary functions like side-shifters, clamps, or rotators
Key Parts: ·
1. Hydraulic Pump:
Driven by the forklift's engine, It draws fluid from the reservoir and pressurizes it, creating flow throughout the system. ·
2. Control Valves: ·
This is the control center, It directs the pressurized fluid to the specific cylinder(s) required for an action
3. Lift Cylinder(Tilt Cyl):
Raise the carriage and forks, (Two cylinders that pivot the mast forward and backward)
4. Hydraulic Oil: Transmit Power
5. Lubricate: Reduces friction and wear between moving parts. ·
6. Cooling: Carries heat away from components. ·
7. Seal: Helps maintain seals in pumps and cylinders
Maintenance Checklist: Regularly check fluid levels, inspect for leaks and damaged hoses, and change the fluid
and filters according to the manufacturer's service intervals.
