ABSTRACT:
The remote controlled screw jack is a modified form of conventional
screw jack that helps to lift the load using motor as a source of energy
and gear box to control the lift of the jack. In this project we aim for the
following:
Arrange & modify the conventional cylindrical lifting jack by putting
extra ring in the center to grip the v belt assembly.
Controlling the jack remotely
To arrange & modify the 12V big D.C. Motor by adding ‘v belt’
pulley at the output shaft.
To construct an angle iron based structure to hold the entire
assembly.
To design & construct a 5Amp dc power supply to run the project
assembly.
INTRODUCTION:
base, a housing, a jack body, a lifting ram which is contained in
the jack body, a servo motor which is contained in the housing,
reduction gears for transmitting the driving power of the servo
ADVANTAGES:
No need of human effort
Jack can controlled both remotely as well as manually
Heavy things can lift easily
DISADVANTAGES:
Power is needed
