There are a number ofsimilar designs which have been proved to be so efficientthat there is no need of releasing the logs on the side of thecar from which they are unloaded. The car is equipped with automatic couplers, air brakesand all appliances required for interchange Fig. 40—Logging Truck Logging Trucks. Detached logging trucks, some-times called logging cars, are frequently referred to asPacific trucks because of their extensive use on thePacific coast where they are employed to haul logs ofvery large diameter and at times of considerable length. The design illustrated has a capacity of 100,000 lb. for apair of trucks and is suited for handling very large designs are used which range in capacity per pairfrom 50,000 lb. to 100,000 lb. The bunk shown is equippedwith chocks which can be easily adjusted in position andlocked and unlocked from the side opposite to that on whichthe logs are discharged. For the large logs hauled on thePacific coast such chocks are better than stakes. Detachedlogging trucks are also used for heavy work in the south,in the Philippine Islands and other places. Bunks areequipped with chocks or stakes of the kind best suited to thecharacter of the logs handled. Such trucks are equipped with couplers on both ends
