Question

Estimate the output of a bulldozer for the following operating conditions.

(i) Material = sandy loam top soil (ii) swell = 25% (iii) Haul Distance = 45m (iv) Mould board size = 3.0m long and 1.0m high (v) Rated Mould board capacity = 3 cubic metre loose volume

(vi) Operating factor = 50 min/hr

(vii) Probable round trip time,

Pushing 45 m @ 2.5kmph = 1.08 min

Returning 45m @ 5.5kmph = 0.49 min

Loading, shifting gear = 0.30 min

Total = 1.87 min
