Additionally, the new bucket can have a longer lifetime than the original one. The calculation was made with SSAB EcoUpgraded.

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).
