1. Source Control: Manufacturing / Gate Acceptance
The core is to eliminate "congenital defects" and ensure that equipment itself meets national standards, which is the basis for safe use.
Choose products from regular manufacturers with special equipment manufacturing licenses. The equipment should come with product certificates, quality certificates and instruction manuals. Welding components such as the boom and main beam need to provide nondestructive testing reports and load test reports.
Equipment gate acceptance: Check metal structures (boom, main beam, outriggers) are free of cracks, deformation, and weld openings, and that core components (rotary bearings, cylinders, wire ropes, hooks) are not damaged. Safety protection devices should be complete and intact. It is strictly forbidden to use "three no", modified, or refurbished equipment.Imported cranes must pass customs inspection and be recognized by domestic special equipment inspection institutions to ensure compliance with national standards such as GB/T 3811 and GB6067.
2. Key Links: Installation / Dismantling / Modification Links (Tower Cranes / Gantry Cranes / Bridge Cranes Focus)
This link is a high-incidence area for accidents and must be operated by qualified units with full control of the process compliance.
The construction unit must have a special equipment, modification, and maintenance license. Operators (installers, dismantlers, commanders) must have valid documents to work. It is strictly forbidden to work without a certificate
Prepare a special construction scheme in advance, which must be implemented after approval by the technical director and expert demonstration (for ultra-dangerous projects). The scheme should clarify lifting position, the selection of lifting appliances, protective measures, and emergency response.
On-site operation control: Set up a warning area and assign a person to supervise. operations are prohibited. In bad weather (gales of force 6 or above, heavy rain, heavy fog), stop work immediately.
After installation / dismantling / modification it must pass the acceptance of the local special equipment inspection and testing institution and obtain a special equipment use registration certificate before it can be put into use. It is strictly forbidden to use acceptance or if the acceptance is not qualified.
