Construction Equipment Production Rate Calculators

Bulldozer Dozing Production Rate Calculator
Minute to Hour Conversion
Minutes/HR
Foot to Mile Conversion
FT/Mile
Total Distance to and from (FT) - Between 60 FT and 600 FT
FT
Average Speed to and from - Between 1 MPH and 6 MPH
Mile/Hr
Blade Payload Volume (LCY) - Between 1 LCY and 8 LCY Capacity
LCY
Material Fill Factor - Between 0.5 and 0.99
Production Efficiency Rate - Between 0.5 and 0.99
LCY/HR = (60 Minutes/HR × Blade Size in LCY × Material Fill Factor × Production Efficiency Rate) ÷ (Push Time in Minutes, Plus Return Time in Minutes, Plus Maneuver Time in Minutes)
Push Time in Minutes OR Return Time in Minutes OR Maneuver Time in Minutes = (60 Minutes/HR × Distance in FT) ÷ (Speed of Dozer in Miles/HR × 5280 FT/Mile)
Material Fill Factor: Ratio of the actual volume of material in the bucket compared to the bucket's rated-heaped capacity.
Production Efficiency Rate: The number of operating minutes per hour divided by 60 minutes. Efficiency is 0.83 when operating 50-min in an hour.

Scraper Production Rate Calculator
Minute to Hour Conversion
Minutes/HR
Foot to Mile Conversion
FT/Mile
Total Distance to and from (FT) - Between 600 FT and 10,000 FT
FT
Average Speed to and from - Between 5 MPH and 25 MPH
Mile/Hr
Bowl Payload Volume (BCY) - Between 5 BCY and 44 BCY Capacity
BCY
Production Efficiency Rate - Between 0.5 and 0.99
BCY/HR = (60 Minutes/HR × Bowl Size in BCY × Production Efficiency Rate) ÷ (Push Time in Minutes, Plus Return Time in Minutes, Plus Maneuver Time in Minutes)
Push Time in Minutes OR Return Time in Minutes OR Maneuver Time in Minutes = (60 Minutes/HR × Distance in FT) ÷ (Speed of Scraper in Miles/HR × 5280 FT/Mile)
Production Efficiency Rate: The number of operating minutes per hour divided by 60 minutes. Efficiency is 0.83 when operating 50-min in an hour.

Hydraulic Shovel Production Rate Calculator
Seconds to Hour Conversion
Seconds/HR
Heaped or Struck Bucket Payload Volume (BCY) - Between 1 BCY and 8 BCY Capacity
BCY
Angle of Swing/Height of Cut Ratio - Between 0.5 and 1.26
Material Fill Factor - Between 0.5 and 0.99
Production Efficiency Rate - Between 0.5 and 0.99
Cycle Time in Seconds - Between 10 Seconds - 30 Seconds
Seconds
BCY/HR = (3600 Seconds/HR × Heaped or Struck Bucket Size in BCY × Angle of Swing/Height of Cut Ratio × Material Fill Factor × Production Efficiency Rate) ÷ (Cycle Time in Seconds)
Material Fill Factor: Ratio of the actual volume of material in the bucket compared to the bucket's rated-heaped capacity.
Production Efficiency Rate: The number of operating minutes per hour divided by 60 minutes. Efficiency is 0.83 when operating 50-min in an hour.

Roller (Compactor) Production Rate Calculator
Conversion Factor - 16.3
Width of Roller in FT
FT
Average Speed - Between 0.25 MPH and 4 MPH
Mile/HR
Compacted Lift Thickness in Inches - Between 1 Inch and 24 Inch
Inches
Production Efficiency Rate - Between 0.5 and 0.99
Number of Passes - Between 2 and 4 Passes
CCY/HR = (16.3 × Width of Roller in FT × Average Speed in Miles/HR × Compacted Lift Thickness in Inches × Production Efficiency Rate) ÷ (Number of Passes)
Note that Using the 16.3 Conversion Factor, Makes it Possible to then Enter the Dimensions as They Are in the Formula. It Takes Care of Going from Mile to YD, FT to YD, and Inches to YD
Production Efficiency Rate: The number of operating minutes per hour divided by 60 minutes. Efficiency is 0.83 when operating 50-min in an hour.
