DOT Equipment Securement Rule of Thumb
Federal Motor Carrier Safety Administration (FMCSA) regulations require a minimum of 4 direct tie-down chains/binders rated for 50% of the equipment weight for any machine exceeding 10,000 lb, plus dedicated auxiliary securement for buckets or hydraulic hammers.
