1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
A wheelbarrow is a carrier, usually having only one wheel, consisting of a tray bolted to two handles and two legs. While known mostly as a device for carrying small loads for the household gardener, a wheelbarrow is often also used in construction and industry for carrying larger loads.
Wheelbarrow is a machine that makes use of a bowel, made of metal used in carrying loads or is a simple machine that helps us life, pull, increase direction of heavy things change the direction of force and increase force.
Wheelbarrows are extremely versatile inventions with many uses around your backyard. Some come
Two wheel wheelbarrows are more stable and can carry heavier loads which is mainly used for industrial purpose.
Two wheel wheelbarrow comes in various designs and configurations heretofore devised and utilized for the purpose of improving the stability of vehicles with improved wheel structures of various methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
The wheelbarrow is designed to distribute the weight of its load between the wheel and the operator so enabling the convenient carriage of heavier and bulkier loads than would be possible were the weight carried entirely by the operator. As such it is a second-class lever. Traditional Chinese wheelbarrows, however, had a central wheel supporting the whole load. Use of two-wheel wheelbarrow is common in the construction industry and in gardening. Typical capacity is approximately 100 liters (4 cubic feet) of material.
A two-wheel type is more stable on level ground, while the almost universal one-wheel type has better maneuverability in small spaces, on planks or when tilted ground would throw the load off balance. The use of one wheel also permits greater control of the deposition of the load on emptying.
1.2 PROBLEM STATEMENT
When working in a large garden, or carry out a lot of landscaping or building jobs,it is always a difficult task carrying heavy loads using a single-wheeled barrow. To overcome this problem a two-wheeled barrow was fabricated. Two wheel barrows are better for heavy loads. This is because you have greater stability at the front, making it easier (and safer) to carry weighty or unbalanced loads.
1.3 AIM AND OBJECTIVES OF THE PROJECT
The main aim of this work is to design and fabricate a two-wheeled barrow. The objectives of the project are:
- To fabricate the machine using available materials
- To increased stability and efficiency of a wheel barrow.
- To fabricate a wheel barrow with side walls and a bottom wall having a front and a back and an open top; handles having lower ends coupled to the bottom of the container and upper ends holdable by a user; rear legs depending downwardly from the container adjacent to the rear end and positionable on the ground; front legs depending from the container adjacent to the front end; an axle formed of a rod with external threads, the axle having a center and opposed ends; brackets secured to the front legs adjacent to their lower extents with apertures for receiving the axle adjacent to its center; cylindrical wheels secured to the axle adjacent to the ends with tires thereon for rotation; two internal bracket nuts threadedly secured to the axle on opposite sides of the center in contact with the brackets at their internal faces; two external wheel nuts threadedly secured to the axle adjacent to their ends in contact with the wheels at their external faces; and intermediate nuts between the brackets and wheels in contact with the external faces of the brackets and the internal faces of the wheels.

A dual-wheel wheelbarrow, often referred to as a two-wheel wheelbarrow or a two-wheeled cart, is a type of wheeled tool used for carrying and transporting heavy loads, typically in gardening, construction, landscaping, and various outdoor tasks. Unlike traditional single-wheel wheelbarrows, which have one wheel in the front, dual-wheel wheelbarrows have two wheels in the front or rear, which provides increased stability and makes them easier to maneuver, especially when carrying heavy or unbalanced loads.
Here are some key features and advantages of dual-wheel wheelbarrows:
- Enhanced Stability: The dual-wheel design distributes the weight of the load more evenly, reducing the risk of tipping over. This increased stability is especially useful when transporting heavy or bulky items.
- Easier to Maneuver: Two-wheel wheelbarrows are generally easier to push and steer than single-wheel wheelbarrows. They are more balanced and require less effort to move, making them suitable for users of varying physical strength.
- Reduced Strain: The dual-wheel configuration allows you to carry heavier loads with less strain on your arms and back, as the weight is distributed between the two wheels.
- Versatility: Dual-wheel wheelbarrows are versatile tools that can be used for a wide range of tasks, including hauling dirt, gravel, mulch, plants, tools, and other materials. They are commonly used in gardening, landscaping, construction, and agriculture.
- Puncture Resistance: Some dual-wheel wheelbarrows feature pneumatic (air-filled) tires that provide better shock absorption and are less prone to punctures compared to solid rubber tires.
- Terrain Adaptability: The dual-wheel design allows for better stability on uneven terrain, such as gravel paths or rough construction sites.
- Dumping Ease: Many dual-wheel wheelbarrows have a design that makes it easier to dump the contents with control. Some models have a single handle that operates both wheels, allowing you to tip the wheelbarrow with precision.
- Variety of Styles: Dual-wheel wheelbarrows come in various styles, including traditional wheelbarrow shapes and cart-style designs. The choice of style depends on the intended use and personal preference.
When selecting a dual-wheel wheelbarrow, consider factors such as the load capacity, tire type, handle design, and overall construction quality to ensure that it meets your specific needs and can withstand the tasks you have in mind
