Common use of SKYLINE YARDING Clause in Contracts

SKYLINE YARDING. A skyline yarding system capable of yarding 1,000 feet external yarding distance uphill must be used. A carriage capable of 50 feet minimum lateral yarding distance is required. The carriage must maintain a fixed position on the skyline while lateral yarding. a. Skyline corridors shall be spaced not less than 75 feet apart unless approved by the Forest Officer. In the case of ridges where fan-shaped settings are required, the minimum distance at the widest divergence will be 150 feet. b. The location of all skyline corridors shall be approved by the Forest Officer in advance of any felling operations. c. Purchaser MAY be required to locate the following prior to approval by the Forest Officer: • all corridors after determining adequate deflection (minimum 5%) • tail trees or tail holds • guyline anchors • blind leads • decking areas d. Clearing width for corridors must be kept to the absolute minimum necessary to accommodate yarding and desired prescription. e. Except for lateral yarding, logs shall be yarded with one end suspended or fully suspended. f. High tail trees required: Tail trees or lift trees suitable to obtain adequate deflection may be required. g. Mobile tailholds or mobile guyline anchors are restricted to areas where it is not necessary to build constructed trails for equipment access unless agreed upon in writing by the Forest Officer. h. In the event that special problems outside the scope of the skyline logging specifications are identified by either party, the Purchaser and the Forest Officer will mutually agree upon the solution. i. If leave trees are used as tailholds and are damaged, they must be harvested.
