Current through Register 2024 Notice Reg. No. 38, September 20, 2024

(a) Portable metal spars shall not be used for any purpose for which they have not been designed and constructed.

(b) Swinging or yarding with a V lead is prohibited, except under the following conditions:

(1) No additional hazards to the logging machine operator, or to other workers in the area, will be created by this operating procedure.

(2) The spar shall be equipped with fairleads for both main and haulback lines.

(3) The mainline and haulback drums shall be located no more than 25 feet from the base of the spar.

(4) No less than six guylines shall be used.

(5) Each guyline on the side opposite the direction of stresses imposed by yarding or swinging must have a breaking strength at least 20 percent greater than that of the mainline used; or one extra guyline at least equal in strength to the mainline used must be placed to oppose the stresses imposed by yarding or swinging in a V lead, and when the lead is changed, the required extra guyline must be repositioned to oppose the stresses of this changed direction of pull.

NOTE: These requirements for additional strength guylines or an extra guyline do not apply to those spars where the mainline and haulback drums are located within the base of the spar, or where lines from these drums are led through sheaves located within the base of the spar. For purposes of determining guyline requirements only, this method of leading main and haulback lines is not considered as creating a V lead.

(c) No yarding or swinging in a V lead shall be performed at less than an angle of 70 degrees formed between the logging machine, fairlead, and the yarding or swing road on either side of the spar, unless the logging machine is controlled in a manner that permits the operator to be stationed in a safe place.

1. Amendment of subsection (b) filed 2-6-85; effective thirtieth day thereafter (Register 85, No. 6).
