To find payload weight for stability and output in tons per hour
5) Connect C 1.8 m
3
(2.35 yd
3
) to F 1600 kg/m
3
(2700 lb/yd
3
) and extend to G to find payload weight
2880 kg (6345 lb).
6) Compare G bucket payload weight 2880 kg (6345 lb)
withmaximumoperating capacities table in this section
to see if the 1.85 m
3
(2.4 yd
3
) bucket can handle the
desired payload. Table indicates the 953D with a
1.85 m
3
(2.4 yd
3
) bucket equipped with bolt-on cutting
edge or teeth and segments has a greater operating
capacity of 3343 kg (7370 lb), therefore stability is okay.
7) Extend Scale G reading 2880 kg (6345 lb) through
Scale A (100) to Scale I to find tons per hour 288 metric
ton/hr (317 U.S. ton/hr).
