EXCEPTION 2: This rule does not apply to machines capable of 360-degree upper structure rotation that are excluded from SAE J1040:May 94 and ISO 8082:1994 standards for ROPS.

  1. Shear or deflector guarding must be:

(a)Installed in front of each cab to deflect whipping saplings and branches.

(b)Located so they do not impede visibility and access to the cab.



EXCEPTION: This rule does not apply to rubber-tired loaders, scrapers and graders.

  1. Machines used for forest activities manufactured on or after July 1, 2004, that are excluded from the ROPS, SAE J1040:1994 or ISO 8082:1994 requirements because they are capable of 360 degree upper structure rotation must be equipped with fully enclosed cabs that meet the requirements of 437-007-0775(2) through (11). These machines must be limited to use on surfaces that are prepared, excavated or constructed of solid material with a slope of less than 20 percent unless the operator’s cab is equipped with the following additional protection:

(a)A Tip Over Protective Structure (TOPS) that meets the requirements of ISO 12117 1997:(E) with the exception of the “Formulae for the determination of energy required” in section 6.1.4 Table 1. The “Formulae for the determination of energy required” in Table 1 is changed as follows:

      1. The lateral energy equation is replaced with 7300(M/10,000)0.9 or 20,000 Joules, whichever is greater where M is the machine mass in kilograms.

      2. The longitudinal energy equation is replaced with 4300(M/10,000)0.9 or 12,000 Joules, whichever is greater where M is the machine mass in kilograms.

(b)An “Off-Boom Side Cab Guard” that complies with the “Front Guard” requirements of SAE J1356: FEB88.

(c)An “Off-Boom Side Cab Guard” that complies with 437-007-0775(14)(b) when the following modifications are made to SAE J1356:FEB88:



      1. Section 3.2. Each occurrence of the term “Front Guard” in this section is replaced with “Off Boom Side Cab Guard.”

      2. Section 3.2.4.1. The term “front of the DLV” on line 3 is replaced with “off boom side of the DLV.”

      3. Section 5.2. Each occurrence of the term “Front Guard” in this section is replaced with “Off Boom Side Cab Guard.”

      4. Section 5.2.3. The term “front of the DLV” on line 2 is replaced with “off boom side of the DLV.”

      5. Section 6.2. The term “Front Guard” on line 1 is replaced with “Off Boom Side Cab Guard.”

  1. Machines used for road construction activities on prepared surfaces with a slope of less than 20 percent are not required to have front and/or top cab protective structures when the machine’s activities do not expose operators to the hazards of yarding, loading or timber falling.

OR-OSHA Admin. Order 2-2008, f. 3/5/08, ef. 3/5/08.



437-007-0780 Protective Structures for Operators, Machines Used On Or After July 1, 2014. Each machine used in forest activities on or after July 1, 2014, that is excluded from the ROPS, SAE J1040 MAY94 or ISO 8082:1994 requirements, because it is capable of 360 degree upper structure rotation, must:


  1. Meet the same requirements as those machines manufactured on or after July 1, 2004, or

  2. Be limited to use on surfaces that are prepared, excavated or constructed of solid materials with a slope of less than 20 percent when handling logs or other materials, or

  3. Have a clear path of travel and be limited to slopes of 40 percent or less when used only as anchors for cable yarding systems.

    EXCEPTION: 437-007-0780 does not apply to machines manufactured before July 1, 2004 that are equipped and maintained with a front and top guard structure meeting the performance criteria of SAE J1356:FEB88 or ISO 10262:1998 Level II.

Stat. Auth.: ORS 654.025(2) and 656.726(4).

Stats. Implemented: ORS 654.001 through 654.295.
