PURPOSE
Design a safe portable ATV lift Easy for one person to handle Lightweight and disassembles for
transport Lifts from frame allowing access to
underside of ATV No electricity required
METHODOLOGY
Frame to be constructed of 4 x 4 x 1/8 in aluminum Stress analysis to be performed to verify the beams
will support the load Top beam will be detachable for transport Lifting arms will be made of steel due to the highest
stress factor Maximum lifting capacity of 1000 lbs. Winch must have a brake so that the load will not fall
when not turning Cable size and tension will be determined to support
the load Pins placed under lifting arms for safety in case of
cable failure
