§ 7.260. Machine brake and driving machine.
(a) A machine brake of the electrically-released, spring-applied type shall be provided. Self-locking drives utilizing a lead-screw or other positive gearing which will stop and hold the carriage with rated load within four inches of down travel after power is removed are excepted.
(b) The driving machine shall be directly connected to the motor, or may be connected to the motor by multiple V-belts, or by a multiple-link, belt-type chain. Where a chain-drive or belt-drive machine is used, a broken-chain or broken-belt device shall be provided to remove power from the motor and brake if the chain or belt fails or slackens.
