Dock levellers for warehouses: what they are, their function

Dock levellers are specialized equipment that is used in warehouse complexes, customs and logistics centers. Such equipment is used in the process of loading and unloading of goods and cargo from vehicles. The presence of such platforms significantly simplifies and speeds up the process.

How dock levellers work

Dock levellers were invented to simplify the work of warehouse center employees who have to deal with forklifts and hand trucks. They unite the floor level in the warehouse with the back of the truck when loading work is being done.

After parking the truck next to the warehouse opening, the dock leveler operator presses a button to raise it. The lift is suited to the maximum until the dock leveller is flush with the truck bed.

The platform remains in this position until the loading operations are completed. It serves as a bridge between the storage floor and the vehicle body. When the work is completed, the dock leveller is lowered to the original level.

Advantages of using dock levellers

The main advantages of dock levellers include the following factors:

• Faster and more convenient loading and unloading operations.
• Reducing the risk of damage to the cargo during its movement.
• Safety of the work performed.
• Reduction of manual labor.

Classification of dock levellers

Dock levellers are usually classified into two main varieties:

• Electro-hydraulic.
• Mechanical.

Electro-hydraulic equipment provides for the presence of a rotating ramp. With the help of such platforms dock cars, in which cargo is transported, with the floor of the warehouse. They are equipped with a rotating ramp, which simplifies the process. Such platforms can withstand a load of 6-10 tons.

There are modifications with a retractable ramp. A distinctive feature of dock levellers of this type is the presence of a telescopic ramp. It makes it possible to perform precise unloading when stopping the truck at an oblique angle to the warehouse floor.

The advantage of mechanical dock levellers is that they do not depend on electrical power and can be used at low temperatures. This is especially important when it is very cold outside. Lightweight small-sized modifications can be operated by one person. They can withstand a load of up to 9 tons.

Recommendations for choosing dock levellers

At the stage of choosing a dock leveller, it is necessary to take into account the size of the truck and the height of the equipment itself. The type of equipment used by warehousemen and the weight of the cargo are also important. The selection of equalizing platforms should be handled by a person with extensive experience in warehouse operations.

Modern modifications of dock levelers are easy to use. Such equipment can withstand high operating loads.
