Sumitomo Heavy Industries, Ltd. and Sumitomo Construction Machinery Co., Ltd. have jointly developed 'InCab@Nav,' a search application for hydraulic excavator manuals. By speaking or typing questions into a smartphone or tablet, operators can search and receive summarized content from the manuals. This initiative aims to improve the utilization of excavator functions and support on-site self-resolution of technical queries. The development was driven by the increasing complexity of construction machinery and the diversification of job sites, creating a need for an environment where operators of varying experience levels can easily access information. The app analyzes natural language queries, extracts relevant information from the manual database, and displays it clearly alongside images. A demonstration and beta release are scheduled for the 8th International Construction & Surveying Exhibition (CSPI 2026) in June 2026.
