GB/T 21956.2-2015 Protective structure strength on narrow-track wheeled agricultural and forestry tractors—Testing method and acceptance condition—Part 2:Dynamic testing method of front mounted ROPS
Abstract
This part of GB/T 21956 specifies the dynamic test methods and acceptance conditions for the strength of front-mounted protective devices on narrow-track wheeled tractors used in agriculture and forestry.
This part applies to pneumatic tire tractors with two axles, where the ground clearance between the lowest points of the front and rear axles does not exceed 600 mm; tractors with a minimum wheelbase of not more than 1,150 mm, regardless of whether the front or rear wheels are equipped with maximum-sized tires; and tractors with a unladen mass (including protective devices and the maximum tires provided by the manufacturer) of more than 400 kg but less than 3,500 kg. The mass ratio should not exceed 1.75. The maximum operating mass should not exceed 5,250 kg.
