Abstract

This portable crane uses a hydraulic system to lift a heavy loads applying only small force. The main advantage of the project is having detail design of the mechanism in the production workshop of BISHOFTU AUTOMOTIVE INDUSTRY; Ethiopia is that it is portable, moveable, and easy for operation. In this project we designed and produced a portable crane which can lift a heavy load with a maximum capacity of 3 ton. The crane has two loaded side bars to make the base and two links (i.e. Vertical column and boom) connected each other by using pin joint. The Vertical column is secured on the cross bar that is welded to the side bars making the base using bolt connection. There are also other bars for supporting purpose which are connected to the basic link (vertical column) using bolt connection. The crane uses four wheels, of which two of them in the front are connected to the base using permanent joint and the rear wheel is connected to the base using roller. Since the crane operates hydraulically there is piston cylinder device which is connected to the vertical column and boom for lifting up and down the objects. The maximum carrying capacity 3 ton, and maximum lifting height is estimated as greater than greater than 2.96m from the ground run by using 3KW electric motor rotating 2830/3620 rpm.
