MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202541071870 A) filed by Beml Limited, Bengaluru, Karnataka, on July 29, 2025, for 'a mechanical brake linkage mechanism and it's hydraulic system of braking in trailer mounted special purpose trolley.'
Inventor(s) include Thyagaraj H S; Manu S; Chethan Shetty; and Surya M.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a mechanical braking system for a towed trailer, such as a Trailer Mounted Special Purpose Trolley. The system comprises a fully mechanical linkage architecture that actuates hydraulic service brakes mounted on all four wheels. A steerable tow bar assembly is connected to the trailer chassis, transmitting force through a telescopic and sliding lever linkage that compensates for angular misalignment and vertical bending. A hydraulic actuator mounted beneath the chassis distributes braking pressure. The system includes a dead-man braking mechanism that engages the brakes mechanically upon disengagement of the tow bar, without the use of electronic sensors. Additionally, a reverse movement locking pin is provided to prevent unintended brake actuation during reversing or manual movement, ensuring that braking occurs only during forward towing. The system enhances operational safety and reliability through its purely mechanical design."
