Machine Travel Brakes
(1)Self-propelled machines built on or after July 1, 1985, must have braking systems as follows:
(a)A service braking system that is the primary means of stopping and holding the equipment.
(b)An emergency stopping system that is a secondary means of stopping the equipment in the event of any single failure of the service system.
(c)A parking brake system that will continuously hold a stopped machine stationary within the limits of traction so the operator may leave the vehicle without the vehicle moving, and to prevent movement of the vehicle while unattended.
(2)The braking systems in this section (OAR 437-007-0755 (Machine Travel Brakes)) must comply with Society of Automotive Engineers’ (SAE) or International Organization for Standards (ISO) Recom- mended Practices:
(a)ISO 11512 MAR95 — Braking Performance — In-Service Crawler Tractors and Crawler Loaders.
(b)J/ISO 3450 JAN98 — Earthmoving Machinery — Braking Systems of Rubber-Tired Machines — Systems and Performance Requirements and Test Procedures.
(c)J/ISO 11169 FEB99 — Machinery for Forestry — Wheeled Special Machines — Vocabulary, Performance Test Methods, and Criteria for Brake Systems.
(3)Self-propelled logging machines manufactured prior to July 1, 1985, must have braking systems installed, tested and maintained in as effective a condition as originally installed by the manufacturer.
