CHAPTER ONE

1.0                                                        INTRODUCTION

In day today life we may have to carry so many goods and objects of various quantities from one place to another especially in offices, schools, colleges, hotels, industries, apartments etc. where the lifts may not be available, may be crowded with people or may be under repair .It is highly tiresome to carry various objects through stairs manually for higher floors for so many times. The various applications may be carrying bundles of answer sheets in a school or a college, carrying furniture in different buildings, different apparatus in colleges, in hospitals etc., carrying electronic items in houses and offices .So there should be a way to carry the objects from place to place in a more comfortable and tireless manner without forcing the user to apply more force.

For this chapter, it is about discussion of the project background, problem statement, objective of the project, and significance of the project, application of the project and lastly scope of the project.

1.1                                                PROJECT BACKGROUND

Trolley is 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.

A typical trolley consists of two small wheels located beneath a load-bearing platform; the trolley usually has two handles on its support frame. These handles are used to push, pull and maneuver the device. The handles may extend from the top rear of the frame, or one handle may curve from the back. An empty hand trolley usually stands upright in an L-shape, and products are usually stacked on top of the platform. When the goods are in place, it is tilted backward so that the load is balanced between the platform and the support frame. Especially if heavy or fragile materials are moved, the person operating the trolley should return it to an upright position carefully, to insure nothing falls off the platform. The front of the frame may be squared off for boxes or curved for drums and barrels. Sometimes, a hand truck also has straps for securing loose freight during transport. Professional material handlers prefer to use a hand truck when moving stackable items such as boxes, crates or packages. Heavier items are usually stacked on the bottom of the hand truck, with lighter objects saved for the top. Hand truck users must be careful not to stack it so high that their vision is blocked or the load becomes unstable. Generally, it is safe to load a hand truck to the level of its handles or the top of the frame. The load is then shifted onto the wheels with a backwards lifting motion. The user can maneuver the cargo by steering it left, right or forward.
