SAE J743_201112

Describes a method to calculate and a test procedure to validate rated lift capacity as presented in commercial literature for pipelayers and tractors or loaders (wheel or crawler), equipped with a hydraulic or mechanically operated sideboom. Rated lift capacity considers hoist mechanism limits, tipping loads, and rope factor. After the lift capacity is validated by testing, a reduction factor is applied to establish the rated lift capacity for the specific pipelayer or sideboom configuration.
