Electric Forklift IP Ratings: Which One Does Your Operation Need?

Q: Can we use a high-pressure water jet to wash an electric forklift?

It is not recommended. Even if an electric forklift is rated at IP65, which is certified to withstand low-pressure water jets, the pressure exerted by industrial high-pressure washers usually far exceeds standard testing thresholds. This extreme pressure can force water past the rubber enclosure seals and cause catastrophic damage to the electronic controller boxes. For maximum safety, we recommend using a standard low-pressure water hose combined with manual wiping.

Can electric forklifts handle the rain? Absolutely. With the right Ingress Protection (IP) rating, your electric fleet can brave the elements without sacrificing performance. Choosing the correct water and dust proof standard is key to keeping your operation running at its best.

In this article, we will break down everything you need to know about IP ratings, including how to read the codes, what they protect against and how to select the right electric forklift to ensure safe and efficient operations.

What is the IP Rating Standard? Understanding the Digits.

Ingress Protection (IP) is a globally standardized system defined by the IEC 60529 standard. It measures how effectively a forklift’s chassis, frame or electrical enclosures are sealed against outside elements like dust and water.

An IP code always starts with the letters "IP" followed by two digits. Each digit represents a specific level of protection, as shown in the chart below.

Signifier of IP Code

The IP rating, which stands for Ingress Protection, is an industry-standard measurement.

Solid Object Protection

The first digit is solid object protection refers to an enclosure's ability to prevent solid objects, such as dust or debris, from entering and damaging the electric motor or electrical system.

Water Protection

The second digit refers to water protection, indicating the enclosure's ability to prevent water or moisture, such as rain or water jets from cleaning.

Summary of IP Rating: Matching IP Ratings to Electric Forklift Operating Conditions

Each electric forklift is designed to handle different tasks and the environment it operates in determines what level of IP (Ingress Protection) rating it needs. Understanding the two digits, solid object protection and water protection, helps you choose the right forklift for the right conditions.

IP Rating	Protection Level (Solid and Water)	Operating Environment
IP54	Protects against dust ingress and splashing water from spills or minor washdowns.	Dusty environment (cement, grain, woodworking, recycling) - Indoor For a warehouse, textile, or printing factory environment with dust and chemical exposure but no requirement for water washdown.
IP65	Fully dust-tight and protected against direct low-pressure water jets from any direction.	Dusty and frequent washdown areas (food/beverage, agriculture, fertilizer plants) - Outdoor For a food manufacturing facility where the forklift handles loading between the warehouse and container trucks during rain and also requires washdown capability.
IP67	Fully dust-tight and protected against temporary immersion in water.	Extreme wet environments (occasional submersion, flooding risk) - Heavy Duty You may find the IP Rating on the controller box or electric motor of a premium quality forklift. It is suited for heavy-duty operation and can drive safely through low levels of flooding.

3 Key Things to Check Before Purchasing a Forklift to Ensure Longer Service Life

1. Check the component IP rating, not just the exterior

Some electric forklifts may advertise an IP54 rating, but this often only applies to the truck frame. The controller and drive motor should carry at least an IP67 rating to ensure the electrical system won't fail when the truck is used in moist conditions. Always verify the IP rating at the component level, not just the overall machine.

2. Food and beverage manufacturing and cold storage

These environments frequently face condensation issues, as trucks move between sub-zero temperatures and normal room temperatures. In addition, the truck must be cleaned regularly to meet strict hygiene requirements. For these conditions, consider choosing a truck with at least an IP65 rating.

3. After-sales service and warranty coverage for the electrical system

Beyond the quality of the forklift itself, after-sales service and warranty terms are essential considerations. If a breakdown occurs, you need a provider who can respond and service the truck quickly to minimize downtime. The service team should also provide maintenance guidelines to help keep your forklift running longer in good condition.

Selecting the right forklift helps protect you from the risk of unexpected expenses.

At Jungheinrich, our electric forklifts are engineered in Germany with IP-rated protection on key electrical components, such as motors and connectors, helping ensure reliable performance even in demanding conditions.

FAQ - IP Rating

Is it possible to use an electric forklift in the rain?

Yes, but it entirely depends on the forklift’s specific IP (Ingress Protection) rating.

IP54 Rated Trucks: These are only protected against light splashes or minor wind-blown rain. Operating them in heavy downpours is not recommended.
IP65 Rated Trucks (or Higher): These models can safely operate in moderate rain and are fully equipped for outdoor applications.

Note for Safety: Regardless of the IP rating, you should never drive through standing water or puddles that are deeper than the center of the wheels to protect the low-hanging electrical systems.

Which IP rating is best matched for an electric forklift used in cold storage?

It is highly recommended to select a forklift with at least an IP65 rating.

Cold storage operations inevitably cause condensation to form on the truck when it moves back and forth between sub-zero storage zones and ambient room temperatures. An IP65 rating provides a critical seal that prevents these water droplets from penetrating the electronic circuit boards (controllers) and motors, ensuring reliable performance.

Can we use a high-pressure water jet to wash an electric forklift?

It is not recommended. Even if an electric forklift is rated at IP65, which is certified to withstand low-pressure water jets, the pressure exerted by industrial high-pressure washers usually far exceeds standard testing thresholds. This extreme pressure can force water past the rubber enclosure seals and cause catastrophic damage to the electronic controller boxes. For maximum safety, we recommend using a standard low-pressure water hose combined with manual wiping.

Is it possible to park an electric forklift outdoors in flood conditions?

Parking an electric forklift in standing floodwater poses a severe risk to its low-mounted electrical systems. However, if an emergency occurs and the truck becomes submerged at foot/floorboard level, follow these critical steps:

Do Not Start the Truck: Under no circumstances should you turn on the ignition or attempt to operate the vehicle.
Isolate the Power: Immediately disconnect the main battery plug to prevent an electrical short circuit.
Relocate and Dry: Tow the forklift to a dry, covered, and well-ventilated indoor area to allow the moisture to evaporate naturally.
Schedule a Technical Check: Before restarting the vehicle, contact a certified technician to perform an Insulation Resistance (IR) test on the motors to ensure the system is completely safe to operate.
