What is forklift load testing? Why is forklift load testing necessary?

19 - 06 - 2025

Summary:

Forklift Load Testing Is a Critical Technical Procedure. It is used to evaluate the operational capability and safety of a forklift before it is put into use or after undergoing maintenance or repair. This process is essential in the field of material handling.

For companies that supply various types of forklifts, like Nhat Lo Phat 168, performing regular load tests not only ensures operational efficiency but also reduces the risk of workplace accidents. In this article, we will explore what forklift load testing is, why it is important, and how the testing process works.

1. What Is Forklift Load Testing?

Forklift load testing is the process of verifying a forklift’s load-handling capacity by having it lift specific weight loads—usually at or above the manufacturer’s rated capacity.

The main purpose of load testing is to confirm that the forklift can safely lift, lower, and transport loads under real operating conditions. This test is usually performed by trained technicians, following safety standards outlined in the “Forklift Technical Safety Inspection Procedure” issued under Circular 54/2016/TT-BLĐTBXH.

Load testing is not only necessary for brand-new forklifts—it’s also essential after repairing key components like the hydraulic system or engine, or after routine maintenance.

2. Why Is Forklift Load Testing Necessary?

Load testing plays a key role in ensuring safety, performance, and the lifespan of the forklift.

2.1. Ensure Real-World Safety

Even though forklifts are built to international standards, real working conditions vary. Load testing verifies whether a forklift can meet those real-world demands and helps eliminate hidden risks before operation.

Example: A 3-ton forklift might perform well indoors but testing it with a 10-meter-long load or on a slope might reveal issues that wouldn't appear under normal conditions.

2.2. Assess Suitability for the Type of Load

Each industry deals with different types of goods—short or long, light or heavy, with off-center load centers, etc. Load testing helps determine whether the forklift you invest in is truly suitable for your business needs.

At Nhat Lo Phat 168, many businesses in steel structure, mechanics, semi-trailers, and warehousing have conducted load tests before deciding to purchase a new forklift.

2.3. Build Confidence Before Handover or Production Use

Load testing provides peace of mind for both the customer and the operators—especially with new forklifts, high-capacity units, or those equipped with special attachments like paper clamps or box clamps.

For forklift suppliers, offering load testing is also a competitive advantage—it demonstrates product quality and builds trust with customers.

3. Types of Forklift Load Testing

Forklift load testing is divided into the following categories:

Static Load Testing

The forklift remains stationary while lifting a test load equal to 125% of the forklift's rated capacity or 125% of the actual working load, not exceeding the design load limit.

Duration: 10 minutes

Pass criteria: The load must remain stable (no drifting), and the forklift’s structure must show no cracks or permanent deformation.

Dynamic Load Testing

The forklift lifts, lowers, moves, and rotates the test load to assess stability, engine performance, and braking system functionality.

Test load: 110% of the rated capacity or 125% of the actual working load, but not more than the design limit

Pass criteria: No load shifting, no structural cracks or damage, and the forklift must operate normally.

Environmental Load Testing

This is a real-world test where the forklift is operated under actual site conditions, such as on ramps, inside warehouses, or in outdoor yards.

Pass criteria: The forklift must perform normally during the test period.

Important Notes for Load Testing:

Only certified forklift technicians should conduct the test.
Use standard test weights, not actual cargo, to ensure safety and accuracy.
Always stay within the permitted load range.
The test area must be secure and clearly marked.
Inspect warranty documents and safety certificates before operation.
