When power interruption, hydraulic leakage, limit failure and other faults occur during crane operation, the new operation should be stopped immediately, and the operator should maintain a safe operating position and not blindly reset the equipment. Timely report the location and phenomenon of the malfunction to the on-site commander and safety administrator, designate a warning and isolation area, and prohibit personnel from entering the dangerous area under the crane arm and lifting object. If the suspended object is in a suspended state, slowly drop the load to a solid and stable ground when the equipment is ready; If there are no safe placement conditions, keep the hanging lock fixed and wait for professional maintenance personnel to arrive for disposal, and prevent non professional personnel from dismantling and debugging without authorization.
Load slipping, swinging of suspended objects, and overloading slipping are high-risk out of control situations, and the core of disposal is to prioritize the safety of personnel. The operator stabilizes the operating handle to avoid violent shaking of the suspended object caused by violent hitting. The on-site commander quickly evacuates the surrounding workers and clears all workstations within the dangerous radius. Based on the on-site environment assessment, existing anchoring and support conditions can be used to cushion the impact of falling objects. It is strictly prohibited for personnel to attempt to block or drag out of control loads with their bodies. Synchronize the cessation of peripheral cross operations, cut off the power of unrelated equipment, and prevent secondary collision accidents from occurring.
After the occurrence of the danger, the on-site person in charge quickly unified the information caliber and simultaneously reported to the project safety department. Mark key information such as the location of the dangerous situation, equipment number, operating conditions, and load weight, and retain on-site images for subsequent traceability and investigation. The guard post will remain on duty until the danger is completely resolved and the equipment is firmly grounded. Do not rush to clean up the scene, preserve the original state of the accident, provide a basis for root cause analysis of the fault, and avoid the recurrence of similar hidden dangers.
The completion of dangerous situation disposal does not mean the resumption of operations. A comprehensive inspection must be conducted jointly by certified maintenance and safety personnel. Focus on checking the core components such as lifting brake, steel wire rope, hydraulic pipeline, torque limiter, sensors, etc., to confirm that the structural components are free of deformation and cracking, and that the braking system functions normally. Test various safety protection devices, verify the effectiveness of the protection trigger logic, issue safety inspection records, and only after approval by the safety manager can the crane be put back into lifting operations.
The implementation of emergency plans relies on personnel proficiency, and the project should regularly organize special drills for scenarios of malfunctions and load loss. Clarify the responsibilities of operators, commanders, guards, and maintenance positions, and correct the habits of panic and misoperation. Update contingency plans based on different aircraft models and lifting conditions, integrate emergency procedures into daily safety briefings, and enable employees to respond in a standardized and orderly manner when facing unexpected situations, reducing safety risks in lifting operations from the source.
