In order to improve the characteristics of the 3000 kg capacity diesel forklifts we are working on, KFD30 Forklift was developed with the aim of increasing performance. After the design and dengeassembly stages of this prototype model, stability tests and performance tests were performed in accordance with TSE ISO Standards. In order to find the maximum performance outputs of the diesel forklift we developed, the test results were taken into consideration and adaptations were made on our prototype model. Surface slopes and velocities that our model could work with and without load were determined. The center of gravity of our model was found to ensure that the load center does not go outside the balance triangle during operation. It is very important that the test results also confirm our original values.

In this study, the effects of hydraulic systems on lift speeds and fuel consumption of diesel forklifts were investigated. Well-known forklift models produced on the subject were examined.Literature review was done on the subject. Forklifts usually with the help of a single pump, the driver steering and lift hydraulic system is working.In our project, as the original value, two separate pumps are used for steering and elevator.In this way, during the operation, the steering is not consumed power. This extra power, which is not used for steering, increases the lifting capacity of the fork in the lift during load lifting. The hydraulic working system of our model is shown in mathematics and physics. Also with solidworks, we found the capacity values for fork lifting. The load lifting capacity values of the hydraulic system of our prototype model and the other hydraulic systems of the equivalent models were explained. The performance of our model seems to be quite good in terms of its load-bearing capacity, among other models that do not apply a dual hydraulicsystem. The design and construction of our model was completed and performance tests were performed. It is also possible to apply the tandem hydraulic system to other forklift models.

Fabricated materials made from mild steel tend to corrode when exposed to the atmosphere overtime, and often result mostly in the complete failure of materials while in service. This research aimed at establishing the relationship between oxidation of mild steel and temperature; the comparison of oxidation of mild steel at high temperature in different atmospheres, and the calculation of the rate of oxidation of mild steel at elevated temperatures. Mild steel finds application in weldable boiler tubes and in weldable turbines requiring very high temperature for its operation, hence this research was carried out at a maximum temperature of 1000 OC and samples were pre-treated in the different atmospheres for 96 hours intervals for 480 hours. The mild steel samples used in this research were labelled samples 1 and 2 and composed 0.19875 %C and 0.19220 %C, respectively. The atmospheres in which the experiment was carried out included hydrogen, sulphur and carbon dioxide. The result of the experiment showed that the rate of oxidation of mild steel followed parabolic relationship, also the rates were different in the different atmospheres and the highest rate occurred in carbon dioxide.

To enhance the fuel economy of automobile and extend the thermal fatigue duration of the typical shock absorbers, energy regenerative shock absorbers have enticed huge attention. Hydraulic electric energy-regenerative shock absorber (HERSA) is a new kind of shock absorber which can regenerate an amount of energy, dissipated as the heat energy in traditional shock absorber. This paper briefly describes HERSA’s working principle, uses AMESim (hydraulic simulation software) to get damping attribute of HERSA as properly as conventional shock absorber through some theoretical and simulation tests. On the basis of simulation outcomes, we differentiate the hydraulic electric energy regenerative shock absorber (HERSA) and traditional shock absorber, and the results revealed that the inclusive performance of the prior is higher to that of the recent, but it shows the theoretical possibilities of HERSA’s structure to improve fuel economy and ride comfort.

Studies have shown that the success of different technology strategies varies with the conditions under which they are derived, e.g. internal or external boundary conditions. Thus, technology strategies fitted to the requirements of an enterprise are a key success factor. Until now, there is little research work done to determine the fit of a technology strategy. Therefore, in our research project, we developed a method to analyse and determine the fit of a technology strategy of an enterprise with its specific internal organizational and strategic context as well as with its external boundary conditions. Prior research on the nterrelationships between technology strategy and influencing factors is mainly focused on single parameters. This article brings an integrated view to the fit of a technology strategy by applying the »fit as gestalts« perspective as well as cybernetic reasoning to the research field of technology strategy.

We designed and fabricated an automated plantain slicing machine out of the need to assist industrial plantain Chips Companies to improve the efficiency of their production process. This design consists of 2 blades as against one in the previous models. The machine was tested with some plantain fingers, to compare its performance with the existing models, This machine was used to slice 342 times as against 50 times in the existing model. All components used to produce this machine were sourced locally thereby reducing cost of production. It is believed that the automated slicing machine will enhance the productivity of the sub-sector.

Contour crafting (CC) is a advanced building printing technology being researched by Behrokh Khoshnevis of the University of Southern California's in the Viterbi School of Engineering that uses a computer-controlled crane to build homes rapidly and efficiently with substantially less manual labor. It was originally designed as a method to construct molds for industrial parts. Khoshnevis decided to adapt the technology for rapid home construction as a way to rebuild homes after natural disasters, like the devastating earthquakes. Using a quicksetting, concrete-like material, contour crafting forms the walls of houses layer by layer until floors and ceilings are set in place by the crane. This great concept calls for the insertion of structural components, air conditioning, plumbing, wiring, utilities, and even consumer devices like audiovisual systems as the layers are built. Automation has been very advanced technology in manufacturing sector but the growth of automation in construction sector has been quite slow. Conventional methods of manufacturing automation cannot construct the giant structures with all internal features. This is the reason behind the slow rate of growth in construction automation. Contour Crafting has a great potential in automated construction of whole structures as well as its sub-components. Using this process, a single house or a colony of houses, each with possibly different designs may be automatically constructed in a single run. This research paper also deals with the application of CC in building habitats on other planets. CC will most probably be one of the very few feasible approaches for building structures on other planets, such as Moon and Mars, which are being targeted for human colonization. Contour Crafting is an emerging technology that uses robotics to construct free form building structures. The research paper aimed at providing a systematic solution for improving the overall Contour Crafting system efficiency in custom-designed buildings. The paper also deals with some practical construction issues.

This paper gives outlines Epicyclic internal gear pump where one sun gear is meshed with three planet gears to achieve variable discharge rate as per requirement. This paper describes techniques for the design, construction, and testing of a Epicyclic internal gear pump. In many applications it is required to drive the actuators hydraulic cylinder or hydraulic motors at variable speed. This is only possible by variable discharge from a variable displacement pump (this pump has very high cost approx Rs.90000/-) so it is not possible to use it. One method employed is to use a pump of higher discharge capacity. But higher capacity means higher cost and higher power consumption. Hence there is need of special pump system at low cost so that the requirement of variable discharge ismet easily without much cost and set up.

Petrol power inevitably finds a very important role in the development of the plant’s economy and technical growth. Inspite of their high thermal efficiency, one cannot ignore the fact about the effect of their exhaust, in the atmosphere. It is a well-known fact that the toxic gases emitted in petrol engines are less than the engines. Due to high cost of petrol, petrol engines are more in use. Anticipating the use of petrol engines, even more in the near future; this system developed can be used to control the toxic gases, coming out of the petrol engines. These toxic gases are harmful not only to the atmosphere, but also to the human & animal race. Objective of this project is to design & fabricate a simple system, where the toxic levels are controlled through chemical reaction to more agreeable level. This system acts itself as a silencer; there is no need to separate the silencer. The whole assembly is fitted in the exhaust pipe; it does not give rise to any complications in assembling it. This system is Very cost effective and more economical. The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is a steep increase in the number of two wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high. The main pollutants contributed by I.C. engines are CO, NOX unburned hydrocarbons (HC) and other particulate emissions. Other sources such as Electric power stations, industrial and domestic fuel consumers also add pollution like NOX, SO2 and particulate matters. In addition to this, all fuel burning systems emit CO2 in large quantities and this is more concerned with the Green House Effect, which is going to decide the health of the earth. Lot of efforts is made to reduce the air pollution from petrol and diesel engines and regulations for emission limits are also imposed in the USA and in a few cities of India. An extensive analysis of energy usage and pollution shows that alternative power systems are still a long way behind the conventional ones. Further developments in petrol and diesel engines, combined with improvements in the vehicles, will make fuel consumption reduction of 40% or more in the future cars.This, in turn, will reduce the CO2 emissions, a gas which is responsible for the greenhouse effect.
