§ 29.12. New installations.
Disconnection of power. Each power press shall be provided with means for disconnecting all power from the press and from the pulley on the press. Any of the following methods may be used:
(1) An individual motor drive capable of disconnecting such power from the press. If the switch or starter is so constructed and located that the motor may be accidentally started, provision shall be made to permit locking or latching in the ‘‘off’’ position.
(2) Tight and loose pulleys on a countershaft with a belt shifter which may be locked or latched in the off position.
(3) Belt perch or idler pulleys to facilitate throwing belts off and on the drive pulley.
(4) A clutch on the drive pulley, with a clutch handle that can be locked or latched in the ‘‘off’’ position. It is recommended that large presses, such as friction clutch presses, have some provision for stopping the press instantly at any point of the stroke.
