Legal Requirements for Crane Inspection and Load Testing

            Under the Ministerial Regulation on the Prescribed Standards for the Administration, Management, and Implementation of Occupational Safety, Health, and Working Environment in Relation to Machinery, Cranes, and Boilers B.E. 2564 (2021), employers are required to ensure that cranes are inspected and tested in accordance with the criteria and requirements prescribed by law.

The equipment and systems covered include:

• Overhead Cranes of all types

• Jib Cranes and Column Cranes

• Electric Hoists

• All types of cranes used in work operations

Regular inspection and testing are essential to ensure safe operation, structural integrity, and compliance with applicable occupational safety requirements.

Crane Load Test Procedure

            The engineering team at EUROCRANE (ASIA) CO., LTD. conducts crane load testing systematically to ensure safety, reliability, and optimal crane performance. The procedure consists of the following steps:

Step 1: Preliminary Inspection Before Testing

Thoroughly inspect the crane structure, electrical systems, wire ropes, hooks, and all safety devices to ensure that the crane is in proper condition and ready for testing, with no abnormalities or defects that could affect safety.

Step 2: Test Load Preparation

Prepare calibrated test weights in accordance with the specified testing requirements, including a Static Load Test at 125% of the SWL and a Dynamic Load Test at 110% of the SWL.

Step 3: Conduct the Load Test

Lift the test load according to the specified testing procedure. Measure the crane girder deflection, inspect the operation of limit switches, braking systems, and control systems, and record the test results throughout the entire process.

Step 4: Post-Test Inspection

Re-inspect the crane structure and critical components after completing the load test to identify any deflection, deformation, damage, or abnormalities that may have occurred during testing.

Step 5: Test Report and Certification

Prepare a comprehensive Load Test Report, together with the relevant certification documents signed by the responsible engineer. These documents can be used as supporting records for inspection and submission to the relevant authorities, where required.

What Are the Risks of Not Conducting a Crane Load Test?

            A Load Test is an essential procedure for verifying the structural integrity and operational readiness of a crane. Failure to conduct the required inspection and testing may result in legal, safety, and business risks.

Legal Risks

• Penalties or fines may apply if the required crane inspections and testing are not conducted in accordance with applicable laws and regulations.

• The crane may be ordered to stop operating until the required inspections and corrective actions have been completed, potentially affecting production operations.

• If an accident occurs due to inadequate inspection or maintenance, the employer may face legal liability, depending on the circumstances and applicable laws.

Safety Risks

• A crane that has not been properly tested may have undetected structural or component defects that cannot be identified through normal operation alone.

• Dropped loads from height can cause serious accidents, potentially resulting in injuries, fatalities, or damage to property and equipment.

• The potential impact on people, property, machinery, and the company’s reputation can be significantly greater than the cost of regular inspection and preventive maintenance.

Business Risks

• Emergency repair costs can be significantly higher than planned preventive maintenance expenses.

• Unexpected crane failures can cause production downtime, operational delays, and disruptions to delivery schedules.

• Incomplete inspection and testing records may affect insurance requirements or factory audits, depending on the insurer and the terms of the insurance policy.

Regular crane inspection and load testing are not only essential for legal compliance but also play a vital role in reducing operational risks and ensuring safe, reliable, and efficient factory operations.

Frequently Asked Questions About Crane Load Testing (Load Test FAQ)

Q: What is the difference between a Load Test and a Por.Jor.1 inspection?

A: A Por.Jor.1 inspection is a comprehensive inspection of the crane system, covering the structure, electrical systems, and safety equipment. A Load Test verifies the crane’s actual load-bearing capability and confirms that it can safely handle its rated capacity. Both processes should be carried out together to ensure safe operation and compliance with applicable requirements.

Q: What test loads are used for a Crane Load Test?

A: The Static Load Test is conducted at 125% of the SWL, while the Dynamic Load Test is conducted at 110% of the SWL. For example, a crane rated at 5 tons would be tested with 6.25 tons for the Static Load Test and 5.5 tons for the Dynamic Load Test, respectively.

Q: Does production need to stop during a Load Test?

A: The crane must be taken out of service during the testing process for safety reasons. However, our team can coordinate with the production department to schedule the test at the most suitable time, such as weekends, planned maintenance periods, or periods of minimal downtime, to minimize disruption to production.

Q: Can Load Testing be performed on cranes of all brands?

A: Yes. We provide Load Testing services for all crane brands and capacities, including cranes imported from Europe, Japan, and China, as well as cranes manufactured in Thailand.

Q: What documents will I receive after the Load Test?

A: Customers will receive a Test Report containing photographs and measurement data from the inspection, together with a Load Test Certificate signed by the responsible engineer.

Q: How much does a Crane Load Test cost?

A: The service cost depends on the crane type, rated capacity, and number of cranes to be tested. Contact our team to request a free, no-obligation quotation tailored to your requirements.
