Product Code:SAE J1824
Title:Specification Definitions--Clam Bunk Skidder
Issuing Committee:Mtc4, Forestry And Logging Equipment
Scope:This SAE Recommended Practice identifies and defines the specifications most commonly used to describe high-speed steel track and articulated rubber-tired clam bunk skidders. The illustrations used are not intended to be descriptive of any existing machine or dictate a combination needed for a particular logging situation. The dimensions indicated are basic and may be supplemented by the individual machine manufacturer.The purpose of this SAE document is to establish a uniform method of identifying and defining the specifications most commonly used to compare various models of this type of equipment.
