Key Aspects for Load Test Of Mobile Crane

Pre-Test Requirements

• Crane Inspection: Ensure the crane is in good working condition, with all safety features and mechanisms functioning properly.
• Load Test Plan: Develop a detailed load test plan, including the load weight, test procedure, and safety measures.
• Qualified Personnel: Only trained and certified personnel should conduct the load test.(Contact the approved third party companies for task)

Load Test Procedure

1. Static Load Test:
• Lift the test load to a specified height (usually 100-200 mm above ground level).
• Hold the load for a specified period (usually 10-15 minutes).
• Check for any signs of instability, structural damage, or excessive deflection.
2. Dynamic Load Test:
• Lift the test load and move it in various directions (e.g., slewing, boom extension/retraction).
• Check for smooth operation, stability, and control.

Safety Measures

• Load Calculation: Ensure the test load is accurately calculated and marked.
• Safety Barriers: Establish a safe perimeter around the test area.
• Communication: Ensure clear communication among test personnel.
• Emergency Procedures: Establish emergency procedures in case of an accident or malfunction.

Post-Test Requirements

• Inspection: Conduct a thorough inspection of the crane after the load test.
• Certification: Obtain certification from a competent authority, if required.
• Documentation: Maintain records of the load test, including results, observations, and any repairs or maintenance performed.
