If you have ever rented a crane for factory, industrial estate, or government work, you have probably heard officials ask for the "PJ.2" document. Many people are still unsure what it is, who issues it, how long it is valid, and how it relates to worksite safety. This article explains everything about the PJ.2 certificate clearly and completely.
What is PJ.2?
PJ.2, or its full name "Annual Crane Inspection Report Form", is an official document under the Ministry of Labour regulations that certifies a crane (including hydraulic cranes and other crane types) has passed a safety inspection in accordance with the Department of Labour Protection and Welfare.
The PJ.2 document specifies the following key details:
- Crane information – brand, model, serial number, rated lifting capacity (tons)
- Inspection date – date of testing and expiration date
- Inspection items – boom condition, wire rope, hydraulic system, brake system, safety devices
- Test results – pass/fail with observations and recommendations
- Inspector name – signing engineer with license number
Who Issues the PJ.2 Certificate?
The PJ.2 must be issued by a licensed mechanical engineer (Gor Wor) at the level of associate engineer or above, or an inspection company authorized by the Department of Labour Protection and Welfare. The engineer conducts a thorough inspection of the crane including mechanical systems, hydraulic systems, safety devices, and actual load testing.
How Long is the PJ.2 Valid?
By law, the PJ.2 is valid for 1 year from the inspection date. This means every crane must be inspected and tested at least once per year. Additionally, if a crane has been involved in an accident, undergone major repairs, or been idle for more than 6 months, it must be re-inspected before use, even if the existing PJ.2 has not yet expired.
Why Do Factories and Industrial Estates Consider It Important?
- Accident prevention – confirms the crane is in working condition with brakes, wire ropes, and safety devices functioning properly
- Traceability – enables verification of when inspections were done, by whom, and the results
- Legal compliance – it is a legal safety requirement that employers must fulfill; non-compliance may result in fines
- Industrial estate requirements – Amata City, Pinthong, Laem Chabang, Map Ta Phut, and other estates in Chonburi, Rayong, and Chachoengsao all enforce this before granting site access
- Reduced liability – in case of an accident, having a PJ.2 demonstrates compliance with safety standards
What Does the PJ.2 Inspection Cover?
The engineer inspects the following main items:
| Category | Inspection Items |
|---|---|
| Structure | Main boom, jib, chassis, and attachment points |
| Rigging System | Slings, drum, pulleys, hook |
| Hydraulic System | Hydraulic lines, cylinders, control valves |
| Brake System | Hoist brake, swing brake, travel brake |
| Safety Devices | Limit Switch, Load Indicator, Anti-two block |
| Electrical System | Signal lights, audible alarms, control system |
| Load Test | Actual load test at 100-125% of rated capacity |
What Other Documents Should You Check Besides PJ.2?
When renting a crane for work in factories or industrial estates, you should also check the following documents:
- Crane Operator Certificate – the crane operator must have completed training and hold valid certification
- Signaller Certificate – the hand signal person who works with the crane operator
- Rigger Certificate – the person who ties and secures the loads to be lifted
- Third Party Liability Insurance – coverage for damage to property or injury to third parties
- Lifting Plan – a plan specifying crane position, lifting angle, weight, and work procedures
- JSA (Job Safety Analysis) – risk analysis for the lifting operation
- PPE Equipment – hard hat, safety glasses, reflective vest, safety shoes, etc.
What Happens If You Rent a Crane Without PJ.2?
- Denied factory entry – most factories will refuse site access, costing you time and money to find another crane
- Legal violation – employers using cranes without PJ.2 may face fines under safety laws
- No insurance coverage – in case of an accident, insurance may deny claims due to non-compliance with safety standards
- Accident risk – uninspected cranes may have hidden mechanical issues such as worn wire ropes or faulty brakes
