Hydrualic ram pressure calculayion5/3/2023 ![]() 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.Ī rivet is a permanent mechanical fastener which can be deployed for joining two work pieces permanently. 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 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. There are also other bars for supporting purpose which are connected to the basic link (vertical column) using bolt connection. The Vertical column is secured on the cross bar that is welded to the side bars making the base using bolt connection. Vertical column and boom) connected each other by using pin joint. The crane has two loaded side bars to make the base and two links (i.e. In this project we designed and produced a portable crane which can lift a heavy load with a maximum capacity of 3 ton. 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. This portable crane uses a hydraulic system to lift a heavy loads applying only small force. It is established from the test results taken for a period of three months, that there is reduction in the time and cost of 70-80%, and 50-60% which in directly increased the productivity of machine and making the process economical. The parts are manufactured accordingly to new design parameters, and the following are installed and the performance characteristics to be determined are time, cost and productivity for this new modified design relative to the old system. Unigraphics is used to model the blade and blade holder, meshing and analysis is carried out by using hypermesh and nastran. ![]() ![]() The system is consisting of modified shear blade, suitable blade holder, hydraulic system according to new tonnage capacity and conveyor system. Modification of hydraulic bale cutting machine is carried out to increase the productivity of the machine, to reduce the time and stress on the workers. The aim of this paper is to present the results of the successful implementation of the redesigned bale cutting machine in Falcon tyre manufacturing company.
