Remote operated fork lift mechanism working model Report pdf Download
In general the forklift can be defined as a tool capable of lifting hundreds of kilograms of weight. A forklift is a vehicle similar to a small truck that has two metal forks on the front used to lift cargo. The forklift operator drives the forklift forward until the forks push under the cargo, and can then lift the cargo several feet in the air by operating the forks. The forks, also known as blades or tines, are usually made out of steel and can lift up to a few tons.
Forklifts are either powered by gasoline, propane, or electricity. Electric forklifts rely on batteries to operate. Gasoline or propane forklifts are sometimes stronger or faster than electric forklifts, but they are more difficult to maintain, and fuel can be costly. Electric forklifts are
great for warehouse use because they do not give off noxious fumes like gas powered machines do.
Forklifts are most often used in warehouses, but some are meant to be used outdoors. The vast majority of rough terrain forklifts operate on gasoline, but some use diesel or natural gas. Rough terrain forklifts have the highest lifting capacity of all forklifts and heavy duty tyres (like those found on trucks), making it possible to drive them on uneven surfaces outdoors.
There are seven classes of forklift that describe the fuel option of the forklift and the use. Each forklift operator must be certified to use on each class of forklift that they will operate.
a. Electric Motor Rider Trucks: –
These forklifts can be equipped with either cushion or pneumatic tires. The cushion tired lift trucks are intended for indoor use on smooth floors. The pneumatic tired models can be used in dry outdoor applications. These vehicles are very versatile and are found from the loading dock to the storage facility. They are generally used in applications where air quality factors need to be considered, i.e. non polluted areas.
b. Electric Motor Narrow Aisle Trucks: –
This forklift is for companies that opt for very narrow aisle (passageway) operation. This allows them to maximize the use of storage space. These vehicles have been developed unique features that are designed to minimize the space occupied by the truck and to improve speed and efficiency.
c. Electrical Motor Hand or Hand Rider Trucks: –
These are hand controlled where the operator is in from of the truck and controls the lift truck through a steering tiller. All controls are mounted on the top of the tiller and the tiller is moved side to side to steer the truck. These vehicles are battery powered with the smaller capacity units using industrial batteries.
d. Internal Combustion Engine Trucks – Cushion Tyres:
– These forklifts are used inside on smooth dry floors for transporting palletized loads to and from loading dock and the storage area. The cushion tired forklifts are lower to the ground than pneumatic tired forklift truck. This allows cushion tired forklift trucks more useful in low clearance applications.
e. International Combustion Engine Trucks – Pneumatic Tires: –
These trucks are most commonly seen in warehouse. They can be used either inside or outside and used in virtually any type of application. Because of the large capacity range of this series of lift truck, they can be found handling small single pallet loads to loaded 40 foot containers. These lift trucks can be powered by internal combustion engines and are available for use with LPG, Gasoline, and Diesel and Compressed Natural Gas fuel systems.
f. Electric and Internal Combustion Engine Tractors: –
These are multipurpose vehicles & are versatile. They can be used in a variety of applications. They can be equipped with either internal combustion engines for outdoor use or battery powered electric motors for indoor use.
g. Rough Terrain Forklift Trucks: –
Rough terrain forklifts are fitted with large flotation type tires for outdoor use on difficult surfaces. They are often used at construction sites
to transport and lift building materials to various job site locations. They are also common with lumber yards and auto recyclers.
SCOPE OF THE PROJECT
The forklift prototype is a four-wheeled that has the ability to follow the direction guided by the operator. There are four wheels including two driving wheels controlled by two motors and two free wheels in front that is able to rotate 360°. With four wheels, both driving
wheels are always in contact with the surface. This project consists of four main stages, which are theoretical design, mechanical fabrication, electronic hardware design.

ADVANTAGES OF FORKLIFT
- Suitable for indoor use.
- Longer life.
- Minimum noise level.
- Eco-friendly operation
- It can be used in hazardous areas.
- Huge advantage of forklift is that they have no fuel cost.
- The best electric forklift is that they have zero emission which causes safe and healthy environment. That is why they can be called the Green Forklift.
- The operation cost is low.
- The life of electric forklift is greater than other types.
- Maintain better control of material management
- Reduce product damages
- Reduce manpower
- Increase productivity
- Suitable to transfer frames
DISADVANTAGES OF FORKLIFT
- The speed is low.
- The capability of lifting weight is lower than other forklifts.
- You can’t handle it until you are fully trained.
- They are usable only indoor.
- The main disadvantage is the area should be properly dry and should have controlled temperature, otherwise you face accidents.
