INTRODUCTION
This project "automatic electro-hydraulic jack for light vehicle garages" has been developed to the needs of small and medium automobile garages.
In most of the garages the vehicles are lifted by using screw jack. This needs high man power and skilled labors.
In order to avoid all such disadvantages, this automatic electro-hydraulic Jack has been designed in such a way that it can be used to lift the vehicle very smoothly without any impact force. The operation is made be simple that even any person can handled, by just pressing the button
WORKING OPERATION
The dash pad switch was activated at the time of any breakdown condition. The control signal is given to the solenoid valve, when the button is activated. The same time, the motor is started which is coupled with rotary hydraulic pump. The oil is suctioned from the oil tank and compressed oil goes to the solenoid valve.
The solenoid valve is activated at the time of dash pad button “ON”. The compressed fluid (oil) goes to the hydraulic cylinder. The compressed oil pusses the hydraulic cylinder piston and move forward. The RAM is fixed at the end of the single acting hydraulic cylinder. The piston moves towards the ground and the ram is lifting the vehicle upwards.
The solenoid valve is deactivated at the time of dash pad button “OFF”. The hydraulic cylinder fluid (oil) goes to the solenoid valve. Then the oil returns back to the oil tank, by the time of deactivating the solenoid valve. Thus the extra oil not required to maintain the oil level in the oil tank.
APPLICATIONS
Ø It is very much useful for Car Owners & Auto-garages. This automatic electro-hydraulic jack is used for lifting the vehicles.
ADVANTAGES
Ø The loaded light vehicles can be easily.
Ø Manual power not required
Ø Repairing is easy.
Ø It requires simple maintenance cares
Ø Maximum height up to 1.5 feet can be reached.
Ø No Oil wastage.
Ø Checking and cleaning are easy, because of the main parts are screwed.
Ø Handling is easy.
Ø Replacement of parts is easy.
Ø The moving parts of this system are cooled by the oil itself used. Thus this project does not require any cooling arrangements.
DISADVANTAGES
1. Initial cost is high.
2. High maintenance cost.
