What are hydraulic tools?
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present.
How do they work?
Hydraulic systems use the pump to push hydraulic fluid through the system to create fluid power. The fluid passes through the valves and flows to the cylinder where the hydraulic energy converts back into mechanical energy. The valves help to direct the flow of the liquid and relieve pressure when needed.
What safety precautions to you need to take?
Always wear safety goggles and protective clothing when using hydraulic equipment. Every jack or ram, whether used individually or in a system, should be completely supported on a solid, firm, non-sliding foundation capable of supporting the load.
How do you maintain them?
To combat dirt and contamination, make sure you follow these preventive maintenance steps. Brush and wipe clean all hydraulic connections before you insert them into a hydraulic pump or remote head. Always use fibre brushes when cleaning your hydraulic tools—never metal-bristled brushes.
Give three examples of hydraulic tools in the workshop (you are likely to come across?)
