Screening plant was being loaded with a 228 komatsu excavator , and the stockpiles with a 700 h wide pad blade and a 344 loader. The blade would alternate between pushing material down towards the 228 , and pushing up and ramping the stockpile for the loader to move material.
For what we plan to do the 621 did everything we asked of it and more . It kept the 228 steady loading considering the material had lots of concrete, rock, and garbage in it.
