A dock leveler is important warehouse equipment which provides a link between the ground surface of the warehouse and the body of the delivery vehicles to help in the transfer of goods while accounting for differences in height. However, when dealing with different types of dock levelers, it may be quite a challenge to determine which one is most suitable for the company. In this guide, we will explain the various types of dock levelers, factors to consider when choosing the right one, and additional features to look for to ensure that you’re making the right choice.
Types of Dock Levelers
Mechanical Dock Levelers
Mechanical dock levelers are known for their strength, convenience in use and high throughput of heavy loads. They are operated mechanically by use of chains, springs and levers and as such are less expensive and more reliable than the automated ones. However, they are not automatic; this makes the loading process to be rather slow and the machines require frequent maintenance.

Hydraulic Dock Levelers
Hydraulic dock levelers are considered to be a top of the line solution for heavy duty use facilities. Hydraulically operated with a push button for the control of cylinders, these provide faster and safer working conditions with reduced human efforts. They are however cheaper in the long run and require minimal maintenance as compared to the other types.

Air-Powered Dock Levelers
Air dock levelers use an airbag as the power source to lift as well as lower the level of the platform. Liquids on the other hand operate in a very simple push button style not as complicated as those of hydraulic models but they need frequent cleaning and maintenance as the airbag is easily punctured or damaged by debris. Hydraulic options are more costly than mechanical ones but they do not have mechanical problems as much as the latter.

Specialized Dock Levelers
If your warehouse has unique needs, consider these specialized dock levelers:
Mechanical Dock Levelers: Mechanical dock levelers are spring-levelers, requiring the operator to pull a chain to position the leveler from the loading dock to back of the trailer bed. This is ideal for wet environments or where electricity is not available.
Vertical Storing Dock Levelers: These hydraulic levelers are designed to store vertically which ensures that they are well protected from the elements and also help in maintaining the right temperature as well as protect them from contaminants such as dust and pests.
Hydraulic Railcar Ramp Levelers: As railcar operations are supported by these levelers, they can be vertically stored and provide a stable loading and unloading process.
Key Factors to Consider
When choosing a dock leveler type, consider the following factors:
Dock Usage Volume
The frequency of use of the dock plays a large role in this decision making process. Hydraulic systems that are more effective in higher usage docks are superior to mechanical or air powered systems that are cheaper but may not be required for frequent use.
Handling Equipment
The kind of equipment that is used in transferring the cargo such as forklifts and pallet jacks may also affect the levelers selected. Some bigger equipment and loads may need the power and the sturdiness of a hydraulic leveler.
Cargo Size and Weight
It is very important to know how large and heavy the items that you will be handling are likely to be. Hydraulic systems are easier and faster to use as compared to mechanical
When choosing the right dock leveler, there are factors that you need to consider such as the load volume that your warehouse requires, the type of equipment that you have and your budget. Every dock leveler has its own benefits and to be able to identify which one suits you best you have to read through the differences.
