Operation of Ground Skidding Machines and Vehicles
(1)Machines must not be operated on slopes in excess of the following limits unless specified by the manufacturer of the equipment.
(a)Rubber-tired skidders — 30 percent.
(b)Crawler tractors, tracked feller bunchers, tracked excavators and loaders — 40 percent.
(c)Other forestry equipment designed for steep slopes — 50 percent.
(2)Operation in excess of the above limits may be permitted for specific limited application or in identified small areas provided the operator and the competent person plan how to safely operate on the steep slopes considering:
(a)Experience of the operator.
(b)Limitations of the machine and the soil conditions.
(c)Direction of travel (traveling straight up and down the slope).
(d)Requirements for turning the machine or vehicle on the slope.
(g)Any other adverse conditions.
(3)Turnarounds must be provided on all skidding roads so operators do not have to backup more than 250 feet.
(4)Towed equipment, such as skid pans, pallets, arches, and trailers, must be attached in a manner which will prevent overrunning of the towing vehicle, equipment or machine.
(5)Tractors, skidders, arches, or logs being yarded must not run over or rub against anchored lines, tailhold stumps, or other rigging.
(6)The yarding machine or vehicle, including its load, must be operated with safe clearance from trees, snags, logs, or other objects that may create a hazard for an employee.
(7)Each machine must be positioned during winching so the machine and winch are operated within their design limits.
(8)No load can exceed the rated capacity of the pallet, trailer, or other carrier.
(9)Arches must be equipped with line guards.
