In today's life, there is a wide variety of forklifts, from the big heavy-duty truck to the one that works between narrow aisles. Now a days advanced parking system is an important issue and day by day its necessity is increasing. In Bangladesh we still use the manual vehicle parking system and that's why we face problems like wasting time and fuel to get free space around the parking lot when we need to park our car which needs a good amount of lighting.
Another problem is the chaos that arises during parking because there is no specific system that allows someone to park somewhere which sometimes causes damage to the vehicles while leaving or in the parking lot.

There are different types of reach forklift that are best suited for a variety of scenarios:[7]. The two forks at the front of the truck slide under palletized loads to lift and transport safely. They offer straightforward operation and have twin forks at the front of the truck that lift and transport the load.
There are different types available, including three-wheeled models that offer better maneuverability, making them perfect for narrow hallways. The carefully calibrated counterbalance at the rear of the truck prevents overbalancing, making it easy to use in mud, ice or even snow. Guided Vehicle Automation known as AGV technology has been introduced to the automated parking system more recently, although AGVs have been used in automated warehousing for decades.
This system is used using a single mechanism that must simultaneously perform the horizontal and vertical movements of the vehicle to be parked or retrieved in the parking system. Jigsaw systems offer the densest form of automated parking as they utilize approximately 95% of the floor area and are often used in smaller systems. This system typically consists of a vehicle lift with a parking space on either side of the lift shaft.
The vehicle lift is simply raised to one of the parking levels of the tower and laterally deposits the vehicles into the parking space. In the decades that followed the development of our country, we came to a situation where the manual parking system in business premises had to be replaced. The manual car parking system creates obstacles and chaos in parking spaces, resulting in wasted time and economic losses.
This will help the staff to park their car without hindrance or waste of time. This will help customers park their car without obstructions, which will give them time to search for more products. If we install automated car parking systems in amusement parks and railway station or any other place, it will attract more people to come to these places.

The two types of ladder control circuits commonly used are the three-wire control regulator and the three-wire motor control circuit. The three-regulator wire control circuit uses retained contact devices to control the up-down and left-right or front-rear. The three-motor control circuit uses momentary contact devices that control the magnetic motor starter.
The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation. Control unit is the unit from which we operate all the systems in this process. Car works to put the car to the parking area or take the car from parking area with forward and backward direction.
The CAD design of the final assembly was done based on the part drawing of the components of the project. Using the tool measurement command of SolidWorks software based on the final assembled CAD design of the forklift parts, which is done according to the assumed dimensions we get.

This section consists of the overall description of the hardware of the automatic parking system and details of the circuits used in the project. The DPDT switch is used to invert the connection between the motors with the power switch to rotate the motor both clockwise and counterclockwise. Finally, all components and parts of the project have been mounted on a wooden surface shown in.
Performance testing of the forklift consists of- The estimation of the maximum load it carries. The maximum mass of the car, fork and forklift stand that can be easily lifted by the forklift has been measured using a mass balancing scale. To calculate the average speed of the forklift, the time has been calculated using a stopwatch for a certain distance.
The distance is then divided by the time for which the average speed of the forklift has been calculated. The time required to store and retrieve is shown in Table: time required to store and retrieve operation-. Lift up-down and move forward-backward have worked correctly at the average speed shown in Table 5.2 and Table 5.3.
These changes in timing are due to the distortion of the wheel connected to the engine, which increases the tendency to increase friction, as well as reduce the grip properties of the rubber used in the steering wheel. In addition, a tilting effect at the base of the fork is caused due to gravity affecting the movement of the fork. Additionally, regular cleaning is mandatory to keep the car park system in good working order, especially with weather-induced problems (road salt can spread to the lift platforms and cause serious damage if not removed).
It is much more efficient to wash clothes using parking garage design and manufacture than manual parking. This keeps traffic free in the urban area and keeps them out of the harmful effects of the car. The townspeople are already using the parking lot and they will be able to understand the whole parking system and share the parking lot with the entire community.
Since manual parking systems are not planned properly, it takes a lot of time to find a parking space, park in and pick up the vehicles. The insurance premium, which is often heavily influenced by the likelihood of accidents or other incidents occurring, using a manual parking system can maximize the potential for property damage, theft, personal injury or death.
