In this kit “Barrel Lifter”, We make a barrel lift for easily to move material and lift from lower place to upper place and vice versa. Trolley can move in supporting columns by using threaded rod .Threaded rod rotated BY motor and motor runs on a 12 volt power supply. These have zero tailpipe emissions resulting in a better and more safe work environment for the employees and the hour intervals between services are usually longer resulting in less cost. In the design of this electric Lifter, braking happens automatically and electrically as soon as the motor power is cut off, resulting in less brake wear. It would be useful for moving items in the garage, loading a pick up truck, moving furniture and lifting heavy casting flasks. We used aluminum square tube, threaded rod, DC motor and nut bolts for fastenings. These type of lifter are for both indoor and outdoor uses. www.kitsguru.com
