1. Qualification Management: Operators must hold a special operation qualification certificate to work. Companies must establish a "one person, one file" training record. Pre-shift meetings must specifically address the day's risks (such as the impact of high-altitude wind speeds) and conduct emergency drills in accordance with the "Regulations on the Safety Responsibility of Special Equipment Users." For example, by simulating a gantry crane wire rope breakage scenario, a full-process simulation of emergency plan activation, power cut-off, casualty transfer, and medical treatment should be conducted to strengthen muscle memory training.
2. Equipment Inspection: Implement a "three checks and three tests" dynamic inspection mechanism: check the braking system's no-load sensitivity (additionally test anti-slip performance after heavy rain), check the frame's verticality (error control ≤ 1‰ of total height during the rainy season), and check safety protection devices (verify lightning protection grounding resistance ≤ 4Ω before thunderstorms). The spacing between wall-mounted frames must be shortened to 4 meters in winds exceeding level 6, and the speed limit for cage top operations in slippery environments must be reduced to 0.3 m/s.
3. Operating Procedures
Strictly adhere to three red lines: Rated load must be publicly displayed and personnel are prohibited from operating on it; immediately stop the machine if a broken wire is found in the wire rope or the limit switch fails; establish an extreme weather early warning mechanism (automatic shutdown when wind speed exceeds 80% of the equipment's wind resistance rating). Visual warning signs must be installed on high-voltage lines within 10 meters of the work area.
4. Maintenance and Upkeep
Implement a tiered maintenance system: Daily inspection of the braking system, safety devices, and wire rope; weekly inspection of the fall arrestor and simulated rope breakage test; monthly inspection to re-measure the verticality of the frame and tighten bolts; annual inspection involving complete disassembly of transmission components and replacement of gears with wear exceeding 5%. A digital ledger is in place, allowing traceability of inspection records via a QR code on the nameplate; the system provides 90-day advance warning for the annual inspection.
