Inspection, signals, controlled operation and handover
Establish readiness before the task
Pre-use checks should follow the actual crane and site instructions, with relevant defects, configuration and outstanding issues understood. A completed form does not prove that every condition is acceptable. Faulty controls, damaged rigging or an uncertain protective function require the controlled competent response rather than one more production lift. Appropriate testing itself needs a safe approved method; this chapter supplies no universal live limit-switch test, bypass or emergency-brake operation.
Keep communication unambiguous
The operator and designated signaling arrangements must provide a reliable control link to the load and landing area. Confirm the agreed commands and transfer of responsibility before movement. Conflicting, unclear or interrupted required communication calls for a controlled stop and clarification, not guessing which instruction was intended. An emergency warning must be taken seriously regardless of who notices the hazard. Remote operation changes visibility and access conditions and does not eliminate the need for site-specific competence.
Manage load behavior through the plan
Smooth appropriate movement reduces relevant swing and dynamic effects. An attached, frozen, snagged or partly supported load can require a force different from its apparent mass. Do not use the crane to drag, pry, force alignment or support people in pinch zones. A planned tagline can assist appropriate load control but must not expose the crew to entanglement or crushing. A permitted test pickup and final landing require the actual competent method; written recognition is not authority to conduct a lift.
Preserve controlled status and learning
Handover should communicate actual condition, defects, weather, active work and restrictions. The correct parking and security arrangement depends on the crane, site and expected conditions, not one generic sequence. Record changes and incidents and verify authorized restoration after maintenance before normal work resumes. Distinguish a safety stop from complete energy isolation and prevent unauthorized access through the actual procedure. Current medical, training, assessment and employer-authorization requirements must be confirmed with appropriate French authorities. Related international operating scenarios reinforce relevant decisions without claiming complete present R487 category performance or replacing the actual practical assessment.
