Production and Machine Selection Nomograph ● To find payload weight for stability and output in tons per hour

Track Loaders

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).

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.
