Rapid Deployment And Special Working Condition Operation Techniques of Cranes in Emergency Rescue

        In emergency rescue scenarios, cranes serve as core equipment, and their rapid deployment efficiency and adaptability to special working conditions directly determine the success or failure of the rescue. It is necessary to balance speed and safety while accurately responding to complex scenario requirements.

        The preliminary survey should be concise and efficient, with priority given to confirming the terrain carrying capacity, obstacle distribution, and rescue core points of the work area. Environmental factors such as weather and wind speed should be evaluated simultaneously to avoid secondary adjustments after deployment. Select suitable vehicle models, prioritize modular cranes, reduce assembly steps, equip skilled teams with division of labor and cooperation, synchronously complete leg erection, counterweight installation and equipment debugging, and achieve seamless connection between "survey in place erection operation".

Simplify the approval process, activate green channels in emergency situations, plan travel routes in advance, avoid congested road sections, and coordinate with transportation departments to open dedicated channels when necessary to ensure that equipment arrives at the site quickly. At the same time, check the operating conditions of the equipment in advance, prepare spare parts, and prevent delays in deployment due to equipment failures.

(1） Complex terrain work

In mountainous, muddy, and soft terrain, steel plates and sleepers need to be laid to reinforce the ground, ensuring that the support legs are fully extended and evenly stressed. If necessary, a cross ditch installation plan should be adopted to avoid collapse risk areas. During high-altitude rescue, accurately locate the operating radius, control the lifting speed, cooperate with traction equipment to maintain the stability of the lifted object, and avoid collisions with buildings and high-voltage lines.

（2） Work in adverse weather conditions

Suspend operations when the wind exceeds the safety threshold. If construction is necessary, use equipment with strong windproof performance and install wind speed monitoring devices for real-time warning. In rainy and snowy weather, it is necessary to clean up the water and snow on the work area, provide anti slip protection for equipment, and apply anti icing agent to the lifting ropes to avoid stiff and broken ropes.

（3） Operations in hazardous and collapse scenarios

When dealing with hazardous chemical spills and building collapses, explosion-proof cranes should be used, and operators should take protective measures, maintain a safe distance, and avoid secondary hazards caused by collisions with suspended objects. At the collapse site, it is necessary to first clean up the surrounding loose debris, confirm the stability of the lifting point, and use a slow rise, slow fall, and small adjustment method to prevent secondary injury to trapped personnel.

        Emergency operations must adhere to the principle of 'safety first, efficiency appropriately matched'. Violations such as overloading and exceeding the working radius are strictly prohibited. A dedicated person must be assigned throughout the process for command and safety supervision, while emergency plans should be prepared in parallel. Response plans need to be formulated for situations such as equipment failures and sudden changes in working conditions to ensure that the rescue process is controllable and traceable.
