Carbon footprint of a wheel loader bucket
This wheel loader bucket has been upgraded from Hardox® 450 to Hardox® 500 Tuf with improved design, making the bucket volume fit for an increased load capacity corresponding to the reduced bucket weight.
a) Previous design b) Upgraded design
Calculation data
Bucket model: Fronteq Eslöv Loader Bucket
Machine class: 35 tonne wheel loader
Diesel consumption, average: 40 litres/hour (assumption)
Machine usage per year: 4 000 hours/year
Design service lifetime: 3 years
Bucket volume: 11 m3 (SAE 1:2)
Weight of bucket (before upgrading): 7 256 kg
Weight of bucket (after upgrading): 6 286 kg (-970 kg or -13%)
Bucket payload capacity (before upgrading): 17 600 kg
Bucket capacity (after upgrading): 18 570 kg (+970 kg or +6%)
Carbon emission savings
Total lifetime CO2 savings: 77 tonnes (1.9 tonnes from less steel produced and 75 tonnes from higher load capacity)
Fuel reduction: 25 073 litres during lifetime (3 years). Corresponding to 40 116 EUR (at 1.6 EUR/litre).
CO2 payback time: 6 months.
Higher capacity in operation
If the extra capacity is used to run the loader machine more for higher revenue, assuming a masses moved revenue of 10 EUR/tonne, 4 000 tonnes moved per day and 330 days in operation per year:
Total profit increase: 740 873 EUR/year (with 72 750 tonnes extra massed moved per year).
