ABSTRACT
Trolley is the main transport for human to carry load. Every trolley has different use and specific use. It is limited to do other job than the specified job. There are some disadvantages for common trolleys such as don’t have stopper,load easy to fall due to slippery surface only suitable for flat road, hard to cornering, cannot load many things, unstable for heavy duty work, high force needed to push or pull the trolley. To reduce this problem, one new trolley will be development that have multipurpose and has not limited to do another task or job. Nowadays, people use trolley to carry heavy load.
There are many type of trolley in the market like industrial trolley, drum truck trolley and platform truck trolley.Many trolleys has been developed with a specific task or job like shopping trolley whichcan be use only for shopping, and transporting traytrolley only to carry trays. In the fabrication, there are many process involve to develop the product such as grinding, joining, measuring, gathering material, cutting material, and finishing process.This project is about design and fabricates a new product of trolley that has multi function. The trolley maximum loads must 200kg, multi use and easy assemble. Its also must reduce the disadvantages of the trolley in the current market like have stopper, and able to lift items up the stairs. Trolley was achieving the objective of this project. The Multipurpose Trolley can function in good condition for example it can support 200 kg load and the Trolley can climb the upstairs.
INTRODUCTION
For this chapter, it is about discussion of the project background, problem statement, objective of the project,and lastly scope of the project. The project involves designing and fabricating a Trolley. As the Diploma final year project allocates the duration of 1 semester, this large man-hour project therefore requires significant efforts of the students to participate. Basically the entire trolley could be divided into three stages, which are concept review and development, designing and fabrication.
The trolley is equipped by using stainless steel 304 2B material which include, rectangular plate steel, round hollow steel, and wheels in manufacturing process by perform MIG welding to joint the parts and etc. The advantages of the proposed trolley to be developed can be seen to be moved such that, man are offered to make their task easier since the trolley will facilitate them to transfer heavy items for instance, computer and etc.
The process of development is initiated from designing the shape of the trolley by considering the function as well. In order to produce user friendly product that is suitable to the consumer, consideration to the ergonomic factor is taken into account. It involves the measurement process before the materials are cut into pieces before joined together.
PROJECT BACKGROUND
Trolley is an equipment used to move heavy loads from one place to another. It can reduce the human burden in their daily lives. This device is commonly used by a large number of industries to transport physical products. Trolley is often used by those who organize and stock merchandise in retail stores restock. When used properly, trolley can protect people from having back injuries and other health problems that can result from lifting and carrying heavy loads.
INTRODUCTION
A literature review is a body of text that aims to review the critical points of current knowledge and or methodological approaches on a particular topic. Literature reviews are secondary sources, and as such, do not report any new or original experimental work.
Most often associated with academic-oriented literature, such as theses, a literature review usually precedes a research proposal and results section. Its ultimate goal is to bring the reader up to date with current literature on a topic and forms the basis for another goal, such as future research that may be needed in the area.
A well-structured literature review is characterized by a logical flow of ideas, current and relevant references with consistent, appropriate referencing style; proper use of terminology; and an unbiased and comprehensive view of the previous research on the topic. The trolley is a mechanism that allowed man to transfer their heavy items such as computers, files and etc to other places. It’s help man to do their work without having a problem due to the heavy loading. Its also helps to reduce pain in waist, back, hand and feet. No mater how light the loading is, people usually will suffocate a large pain in their body if lifting the items in many times. So, this is when the people rely upon a trolley that can do items transferring many times with just a little effort. From the statement above conclude that the trolley playing a major role as an items transferring mechanism for people without having a problem of doing that. A trolley also functioned as a helper to people to hold items orderly while transferring between rough lands.
Multipurpose Hand Trolley Four Wheels
The multipurpose hand trolley four wheels easy to use, strong, and easy to operation. This trolley have four wheels The total of trolley size 1450mm x 550mm x 460mm and the total plate width is 180mm This trolley can handle the load of 250kg and below.
The advantage of this trolley are, light in weight, durable, top grade and easy to operation. It is extensive suitable for warehouse and office.
The disadvantages of this trolley is loads fell easily when filled with a large quantity and small items can not be loaded.
FABRICATION PROCESS
After designing phase, comes fabrication process. These processes is about using the material Selection and make the product base on the design and by followed the design dimension. Many methods can be used to fabricate a product, like welding, fastening, cutting, drilling and many more method. Fabrication process is difference from manufacturing process in term of production quantity. Fabrication process is a process to make only one product rather then manufacturing process that focus to large scale production. In the project fabrication process needed to make the base plate, framework of display board and display board. Fabrication process was used at the whole system production. This was include part by part fabrication until assembly to others component
