350D LC Excavator Production Estimating Program
|
|
ESTIMATING PURPOSES
ONLY |
|
Program
calculates hourly production to load dump trucks, trenching, charge hoppers,
etc.
|
|
Production
is continuous except for excavator repositioning (no wait time for dump
trucks).
|
|
Place
cursor on red triangles for explanation.
Swing cycle times are based on proper
|
|
|
matching of
arm, bucket, and material.
