Standardization of Digger Derrick Capacity Ratings 830194

Utility digger derricks are usually classified by their capacity rating with the booms fully retracted and fully elevated. This is not a practical working position. A more meaningful comparison of useful lifting capacities can be made when the rating classification is the load which can be lifted by the digger derrick lift cylinder at a ten foot load radius. Lifting capacities at lower boom angles are also important for digger derrick applications.
