International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2022

In construction sites there is a use of dumper for loading and unloading a material like sand, gravels, and other infrastructure materials. But they still used manual operated conventional dumper to dump the materials. they are dump material only in one side only that is rear side and that's the reason sometimes it's quite difficult to dump material in some compact places where the convention dumper is difficult to used. And this research paper mainly focused on above mentioned difficulty. To deal with this we are making a automatic three way pneumatic dumper mechanism so that they can be dump material in rear side as well as left and right direction also. and with the help of Arduino software the motion of the dumper can automated instead of manual use. It can be reduce labour work, save time, and increase the workability.

Warehouses are large plain and commercial buildings used for storage of goods by manufacturers, importers, exporters, wholesalers, transport businesses, customs department. Earlier days unloading, stacking and loading operations were being done manually, which requires a huge number of porters to handle the material. For the last few decades, people are using fork lifts, conveyors and Hook Cranes to perform the unloading, staking and loading operations. Conventionally, these forklifts are powered by I. C. Engines which emit exhaust gases inside the warehouses. So, in order to overcome such drawbacks, D. C. motor driven forklifts were developed. But they cannot be used for heavy loads. They also require large turning radius / moving space. The technical solution that is deemed feasible and capable of addressing the above mentioned issues is an electrically operated overhead travelling cargo handling machine which reduces the turning radius and increases the storage area. In this overhead travelling forklift, we have a column to which the fork is attached. This column can move along the long travel and cross travel with ease. In this we use a bevel gear which helps us in slewing of fork. The fork lift with the help of AC motor instead of DC motors and I. C engines, which require refueling or recharging time. As a part of our project dissertation, we are making " Overhead travelling cargo handling machine for warehouses " which might be helpful in the reduction of exhaust emissions from forklift exhaust in warehouse as it operates with electric energy. The main objective of this project work is to study the physical properties, optimum parameters of the process and the working rate of existing techniques of material handling (Cargo handling) and develop a design approach to provide a better working environment to the workers working in warehouses and subsequently increase the storage space.

Sanitation is a hygienic means of promoting health by preventing human contact with waste. As such, safe removal and disposal of municipal solid waste within a community is critical in the environmental sanitation. A number of small waste collection trucks such as tricycles are in use in Ghana and other developing countries. This paper presents a design of lift-tipping mechanism for small solid waste collection trucks that enhances the safety of the waste collection component of the sanitation management. A five bar mechanism is developed with one degree of freedom. The prototype of the system built is such that for manual operation system, reverse paddling of the tricycle cycling paddle is employed in lifting and tipping. The test of the prototype result shows the torque requirement of the system ranges between 16.0 Nm and 25.0 Nm with a maximum load of 50.0 kg. A height of 1.15 m and tilt angle of 38o were obtained.

In this paper the author presents a wheel loader equipped with side dump bucket modelled with modern technologies used in mechanical engineering fields (SolidWorks, Femap and NX 11 manufacturing). The various behaviours that acting on the bucket during technological process were analysed with finite element method. The obtained results validate appropriate dimensioning of main elements of bucket ensemble in proposed constructive variant.

This project work "design and The "construction of a three-axis rotating trailer utilising a pneumatic system" was conceived after research into the difficulty of emptying materials. Our investigation of a few car garages revealed the following that generally some troublesome strategies were embraced in emptying the materials from the trailer. The material will only be emptied in one direction by the trailer In small compact highways and small streets, it is difficult to empty the materials. All three sides have been successfully unloaded the trailer in our work. The compressor engine, which stores compressed air when the vehicle is running, is connected to the automobile engine drive. When the valve is activated, the pneumatic cylinder is used to activate the compressed air Spur gear is used to rotate the trailer in three directions, making it simple to dump cargo in narrow streets and roads.

Conventional tipper mechanism an unload materials only at the backside of the tipper using hydraulically operated boom which may cause the problems of road blockage in the limited space area. The prototype model of three direction movement tipper overcomes the problem of unloading the vehicle on side way by using BOOM (D.C. Motor operated). By using Boom the material can be unloaded in all three directions as per requirement. The prototype is developed and tested foe its movement in all three possible direction to unload the materials in the tipper trolley and monitor the inclinations for its gradualism (linearity). The results of inclination of the tipper in all three directions are obtained with respect to time period with material and without material as 22.80 0 and 23.24 0 for 100 seconds of operation of tipper respectively.

–-Mechanical forklift is an improved and advance technology that helps brought about revolution in the mechanical industries today all heavy engineering company uses it. Widespread use of the forklift truck had revolutionized warehousing practices before the middle of the 20th century. A mixture of material handling systems is in the use, exact from that entirely physical to the ones that are semi-automatic but manually controlled. Forklifts have revolutionized warehouse work. They made it possible for one person to move 100 kg at once. Well-maintained and safely operated forklifts make lifting and transporting cargo infinitely easier. This is the general description of a normal forklift truck.. In the warehouses forklifts are the most expensive machines. The study pays special attention to the travelling of these machines. Factories, industries and storage go downs need forklifts and cranes for storage and moving large goods. Also there are a number of goods weighing around 40 – 60 kg that are comparatively lighter but cannot be moved around easily by human labour. To fill this need we here propose a three wheel drive forklift to lift and transport such medium weight goods across factories & industrial warehouses. The three wheel drive is a fast, efficient and low power consumption vehicle that does not require much space to move around. The mini forklift will run on a hub motor and can drive small weight with pickup arrangement across small distances easily. For this we use a mini three wheel vehicle body frame designed with a platform with motorized wheel mounts. It has a perpendicular handle ahead to hold on as well as take turns. To make the project work more realistic, much importance is given for practical orientation, therefore a prototype module is constructed for the demonstration purpose. This module simulates the real working system & based on this technology with slight changes in the structure & motor ratings, the system can be converted for real applications.

Reclaiming of coal, iron ore and grain are necessary/essential in industries like power plants and mining. Manual handling or usage of dozers for reclaiming operation requires lot of time, man power, and money and also involves risks of accidents. In earlier days both the manual and dozer operations were suitable for reclaiming of above materials due to lesser quantities and cheaper man power availability in the market. Earlier days the bucket wheel reclaimer on cantilever beam and requires huge counter weight mandating heavy structure that leads to high power consumption for the movement of equipment. Due to heavy weight and high power motors, the initial investment on the machine is also high. And it has a long cantilever and counter weight at the height of almost 100 to 150 feet " that reduces the stability of equipment. Chances of bucket wheel hitting to other machines or working areas is also possible due to long beam due to the negligence of operator. In linear type, it requires less counter weight and less power consumption. This paper involves function design, motor power calculation, load balancing, fabrication and testing of proto type linear motion bucket reclaiming machine with 4 major movements namely long travel, bucket wheel rotation, lowering and conveying.
