The Technology of Assistant Rescue Accessory for City Earthquake Disaster Based on the Large Construction Machinery

City epicentral earthquake relief is a global major challenge of earthquake rescue and China has had a painful lesson in this aspect. The recent earthquake relief were summarized and the corresponding analysis for the status of application of large mechanical equipment are made in the domestic and international earthquake rescue and the existing problems. Some solution about the interface and operating technology for some common subsidiary tools were presented. In this way,they can make a rapidly transformation from common large construction machinery equipment to special rescue devises,which can achieve professional large rescue equipment work on site in the early time and satisfy urgent needs of the future urban epicentral earthquake rescue.
