This grapple is popular choice for medium truck loaders, It can be an option for mini excavators if bushy material, or large stems, up to 40" in diameter are loaded. 

If the grapple is used with equipment that have more lifting capacity than miniexcvators, then one can opt for a heavier rotator such as the R6
