MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202631010712 A) filed by Indian Institute Of Technology (Indian School Of Mines), Dhanbad, Jharkhand, on Feb. 2, for 'instantaneous rake loading system (irls) - simultaneous stationary railway rake loading using elevated static pre-weigh bins.'
Inventor(s) include Prof L A Kumaraswamidhas; Mr. Dharma Raj H; Prof. V M S R Murthy; Mr. Aayan Rai; Mr. Uttam Kumar Mahto; Mr. Saurabh Raj; and Mr. Akshit Bhagat.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an Instantaneous Rake Loading System (IRLS) developed for fast, accurate, and operationally simple loading of bulk material into railway wagons (501). Conventional mechanised systems rely on travelling wagon loaders or sequential loading under locomotive creep motion, both of which involve dynamic weighing, longer loading times, and higher operational dependency. The IRLS eliminates these limitations by adopting static pre weighment (402) and stationary whole rake loading. The system comprises multiple static pre weigh bins (401) mounted on an elevated platform (102) above the railway track (504), each corresponding to a wagon (501) and designed to store material equal to its rated capacity. These bins (401) are pre loaded independently through an elevated conveyor (301) with travelling tripper (201) and boom arrangement (203), decoupling feeding and weighing from the loading stage. When a rake is positioned beneath the bins (401), a single command actuates hydraulic discharge gates (403), releasing material simultaneously into all wagons (501). This enables complete rake loading in less than one minute, ensuring high accuracy, reduced operational complexity, and improved reliability compared to conventional rapid wagon loading systems."
