Abstract

Abstract: In order to improve rescue efficiency of construction machinery, firstly, existing problems and difficulties were analyzed, including multiple indicators and conflicts in evaluation of multi-functional rescue attachments' performance. Then, a comprehensive evaluation system of their performance based on principle of “safety and efficiency” was established from three levels, objective, standard and indicator levels and five aspects including production, basic function, transportation capacity, safety and operational ability. Finally, the improved AHP-fuzzy comprehensive evaluation method was used to evaluate performance of three kinds of multi-functional rescue attachments. The results show that their comprehensive performance ranks from high to low asbreaking-opening rescue attachment, shearing-expanding rescue attachment, and grabbing-lifting rescue attachment.Moreover, evaluation results based on the above system are basically consistent with judgment results based on experience.

Key words: multi-functional rescue attachments, comprehensive performance, evaluation system, analytical hierarchy process (AHP), fuzzy comprehensive evaluation method
