In today's dynamic world, where technology is constantly evolving, industrial forklifts become an indispensable part of cargo transfer processes in small and medium-sized enterprises. One of the key figures in this field is the pallet truck, which enables horizontal cargo transport.

In this post, we will explore how pallet trucks work by examining their construction and key functions.

Pallet Truck Construction

To better understand how pallet trucks work, we first need to familiarize ourselves with their construction. Although there are different types of pallet trucks, their basic construction is similar. In this diagram, you can see the key parts of manual pallet trucks. Each of these parts has a specific function that contributes to the efficiency and safety of the pallet truck.

Handle

Allows you to move the truck in the desired direction with both hands.

Control Lever

Set in one of three positions, allowing lifting, lowering, or transferring of the load.

Steering Wheel

Enables precise steering of the forklift with a small turning radius.

Load Rollers/Wheels

Enable the movement of the forks forward and backward.

Forks

Used for lifting pallets or boxes.

Pallet Truck Functions

The hydraulic system is often used to lift the load in pallet trucks, regardless of the model.

Here's how the mechanism of manually guided pallet trucks works:

• Start by lowering the control lever to close the lowering valves and retain hydraulic oil in the lifting cylinder.
• Move the steering wheel, pushing oil into the lifting cylinder, raising the forks independently of the load.
• Lifting creates a vacuum, and hydraulic oil is drawn from the reservoir into the lifting cylinder.
• Pressing the steering wheel, a second return valve sends hydraulic oil into the cylinder, lifting the load.
• Repeating this process, the forks are raised higher.
• When you reach the desired height, place the control lever in the neutral position to transfer the load.
• To lower the load, pull the control lever.

Different Types of Pallet Trucks

Although different types of pallet trucks may have different constructions, the basic operating principles are the same. Electric pallet trucks use an electric motor to control the hydraulic pump, while manual pallet trucks require physical effort to operate the pump.

Frequently Asked Questions

What is the construction of pallet trucks?

Pallet trucks can have different constructions, but the basic parts are the handle, control lever, steering wheel, load rollers/wheels, and forks.

What is the function of the hydraulic system?

The hydraulic system enables lifting the load, creating hydraulic pressure.

Do different types of pallet trucks work differently?

The basic operating principles are the same, but differences occur in the type of transmission (electric or manual) and additional features such as scales or materials they are made of.

Conclusion

Pallet trucks are crucial for efficient cargo transport in the industry. Regardless of the type of pallet truck you use, understanding the basic operating principles allows you to use this important equipment safely and efficiently. Always follow the manufacturer's instructions and maintain pallet trucks to ensure long-lasting and safe operation.
