8. Paragraph (f) Machines

c. Paragraph (f)(3)(i) - Protective structures for logging
machines. OSHA has revised the final rule to require that the following logging
machines placed into initial service after February 9, 1995 have FOPS and/or ROPS:
tractors, skidders, swing yarders, log stackers, log loaders and mechanical felling
devices, such as tree shears or feller bunchers.
d. Paragraph (f)(3)(ii) - ROPS specifications. OSHA has revised
the final rule to require that logging machines manufactured after August 1, 1996, be
equipped with rollover protection structures (ROPS) that are tested, installed and
maintained in accordance with the Society of Automotive Engineers (SAE) J1040, April 1988,
Performance Criteria for ROPS for Construction Earthmoving, Forestry and Mining Machines.
(1) The final rule also requires that ROPS and FOPS, which are required on logging
machines placed into initial service after February 9, 1995, must also meet the
requirements of SAE J397, April 1988, "Deflection Limiting Volume - ROPS/FOPS
Laboratory Evaluation." The 1988 standard updated a 1979 SAE standard on deflection
limiting volume. There is no significant functional difference between the criteria of the
1988 and 1979 SAE standards. Therefore, ROPS and FOPS certified to meet the requirements
of either the 1988 or 1979 SAE standards shall be deemed to be in compliance with the
final logging standard.
(2) OSHA will collect and distribute a list of model numbers of machines that will
show, with respect to manufacturers who, as of July of 1994, were making equipment not
complying with the ROPS requirements of J1040 April 1988, the last model number or serial
number on noncomplying equipment they manufactured or, if as of August 1, 1996, they are
still manufacturing such equipment, the latest serial number of such equipment
manufactured on or before August 1, 1996.
