Material handling is loading, moving and unloading of materials. To do it safely and economically, variants of tackles, contrivances and equipment are utilized, when the materials handling is referred to as mechanical handling of materials. One of the definitions adopted way back by the American Materials Handling Society is, Materials handling is the art and science involving the moving, packaging and storing of substances in any form. A slat is fundamentally a thin narrow piece of metal, plastic or wood. A slat conveyor is one the type of material handling equipment which is utilized in many industrial applications. Slat conveyors are great for assembling products on either a moving assembly line or on the line at each works station while the line is ceased. Withal, they provide a great stable working surface. The above reason makes the slat conveyor famous in material handling industry. This paper describes the design calculation of slat conveyor system for the company who is in the process of automation of plant. Utilizer need dedicated conveyor system for 15 stations tractor assembly line. Apart from this the optimization of slat is done which was additionally the component of our work. With the proposed conveyor system physical work cost will be minimized withal the conveyance of material handling cost will be abbreviated.

In the process or manufacturing industry, raw materials need to be transported from one manufacturing stage to another. Material handling equipment are designed such that they facilitate easy, cheap, fast and safe loading and unloading with least human interference. For instance, belt conveyor system can be employed for easy handling of materials beyond human capacity in terms of weight and height. This paper discusses the design calculations and considerations of belt conveyor system for biomass wood using 3 rolls idlers, in terms of size, length, capacity and speed, roller diameter, power and tension, idler spacing, type of drive unit, diameter, location and arrangement of pulley, angle and axis of rotation, control mode, intended application, product to be handled as well as its maximum loading capacity in order ensure fast, continuous and efficient movement of crushed biomass wood while avoiding fatalities during loading and unloading. The successful completion of this research work has generated design data for industrial uses in the development of an automated belt conveyor system which is fast, safe and efficient.

The paper presents an analysis of the possibility of optimizing the drive of slat conveyors, which primarily refers to the choice of the drive chain and the number of drive units. The basic characteristics of slat conveyors, as a mean of continuous transport, procedures for calculating the basic parameters and the choice of basic elements of the conveyor are presented. Cases with one angular and combinations with several line drive units are considered. In order to observe influential parameters, variants with different route lengths and line weight of transported material were considered. At the end of the paper, the obtained results were analyzed and appropriate conclusions were made.

Material handling systems is used for continuous movement of material from one point to another. They are uncommon in service systems. Material is conveyed everywhere in a factory or warehouse—before, during, and after processing. Material handling work should be minimized without compromising production or the level of quality required of the operation. Material handling operations should be mechanized and/or automated where feasible to improve operational efficiency, increase reaction, improve uniformity and unavoidability, decrease operating costs, and eliminate recurring or potentially unsafe manual labor. The intelligent system approach to selection of conveyor provides advantages of unbiased decision making, greater availability, faster response, and reduced cost as compared to human experts. This paper discuses the design and analysis of material handling system-Conveyor system.

This manuscript deals with the design, analysis and optimization of a Slat Conveyor for bag handling at the Airports. The requirement here is to transport the bags from loading station to the unloading station which covers the distance of 28 metres. The specification provided are the approximate weight of each bag, the total weight to be transported between the stations and the height upto which it is transported. The Input parameters are reference to the design calculations.Proper material selection is done using appropriate standards like the ASME , CEMA and Ashby standard. With the proposed conveyor system the weight of the base frame will be reduced and the fatigue strength/cycle of drive shaft will be increased using the appropriate materials.

The aim of this project is to produce the mechanical design of a conveyor system for unloading heavy goods. The current unloading process of heavy goods like LPG gas cylinder is improper which may lead to some major problems. This design of conveyor system will overcome those mistakes done during unloading of LPG gas cylinders. The thorough study is to be done on various designs of conveyor system. From the data analyzed at simple and cost-efficient design of conveyor belt is done. Design of this conveyor system is performed using Solid works and Computer Aided Drafting (CAD).

The main aim of this paper is to study various material handling equipment & systems used in an Industry for various material handling, and Study various Modern Technique. Material Handling and is required by many safety regulations, national consensus standards and manufacturers. It is the purpose of the daily condition usage to ensure that the overall equipment mechanical and electric components of the equipment have been maintained in a safe and serviceable condition and are functioning properly according to the original equipment manufacturer's specifications. It is the purpose of the inspection test to ensure by actual test that the equipment is capable of safely lifting and moving the rated load through all designed motions. The inspection and load test do not take into account the duty factor of the equipment.

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.
