Introduction
  • The motorized lifting 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
  • a) Arrange modify the conventional
    cylindrical lifting jack by putting extra ring in
    the center to grip the v belt assembly.
  • b) To arrange modify the 12V big D.C. Motor
    by adding v belt pulley at the output shaft.
  • c) To construct an angle iron based structure
    to hold the entire assembly.
  • d) To design construct a 5Amp dc power supply
    to run the project assembly.

LIFTING JACK
  • Jack (tool), mechanical device used to raise or
    otherwise exert a force on an object too heavy to
    deal with by hand. A common example is the
    automobile jack, which is used to elevate the end
    of a car by a system of ratchets, gears, and
    screws.
  • Lifting jacks are used for leveling or
    positioning heavy equipment, or for supporting
    structures. Common types of lifting jacks include
    bottle, inflatable, pallet, ratchet, scissor,
    screw, service or floor, toe, and transmission.

TRUSS
  • Truss is a metal frame used for hanging. Trusses
    are very strong and able to carry extremely heavy
    loads. Most truss is now made of aluminium for
    weight reasons and sections can be bolted
    together to produce long pieces. Its strength
    allows it to hold everything from lighting to
    drapes.

GEARS
  • Gears, toothed wheels or cogs are positive type
    drives which are used to transmit motion between
    two shafts or a shaft and a component having
    linear motion, by meshing of two or more gears.
    They have advantage over other drives like
    chains, belts etc. in case of precision machines
    where a definite velocity ratio is of importance
    and also in case where the driver and the
    follower are in close proximity the downside is
    that gears are more expensive to manufacture and
    their operating cost is also relatively high.

BELTS
  • Belts are used to mechanically link two or more
    rotating items. They may be used as a source of
    motion, to transmit power between two points, or
    to track relative movement.
  • As a source of motion, a conveyor belt is one
    application where the belt is adapted to
    continually carry a load between two points. A
    belt may also be looped (or crossed) between two
    points so that the direction of rotation is
    reversed at the other point.

ELEMENTARY D.C. MOTOR
  • When D.C motor is supplied to the armature
    through the brushes and commutator, magnetic flux
    is also build up around the armature. It is this
    armature flux that interacts with the magnetic
    field in which the armature is suspended to
    develop the torque that makes the motor operate.
