Introduction
In recent years, fluctuations in fuel prices and tightened environmental policies have posed severe challenges to the engineering industry. Eco-friendly mini excavators, with their technical advantages of low energy consumption and low emissions, have become the preferred solution for many enterprises to reduce costs and increase efficiency. Hengwang has been deeply engaged in the construction machinery field for more than ten years, and its various eco-friendly mini excavators have achieved a fuel consumption reduction of over 50% through technological innovation, helping customers significantly reduce operating expenses.
I. High fuel consumption pain points of traditional excavators
Although traditional diesel-powered excavators have strong power, their fuel efficiency is generally lower than 30%.
II. Three core technologies of eco-friendly mini excavators
To address industry pain points, Shandong Hengwang Group has launched four series of eco-friendly mini excavators solutions:
Pure electric drive system (HW10-3E)
Zero emissions and silent operation: Equipped with a 150AH ternary lithium battery pack, operating voltage 72V, stable torque output
Intelligent battery management: Supports 220V fast charging, fully charged in only 4 hours, with 8 hours of full-charge battery life
Applicable scenarios: Indoor decoration, precision construction, night operations and other scenarios with high environmental requirements
Hybrid energy-saving system (HW10-3C)
Dual power switching: Diesel engine and permanent magnet synchronous motor work together, reducing fuel consumption by 40%
Energy recovery technology: Automatically stores energy during braking/downhill, reducing energy loss by 30%
Representative model: HW10-3C (bucket capacity 0.025m³, price ¥XX0,000)
Intelligent fuel-saving mode (HW-20W)
ECO driving mode: Automatically adjusts engine speed to match the hydraulic system
Load sensing system: Dynamically adjusts power output according to working conditions
Application case: After being used by a municipal engineering team, the average monthly fuel cost decreased by ¥12,000
III. Real case: Green transformation practice of an Australian organic farm
Project background: A 120-hectare organic vineyard in Victoria, Australia, needed to purchase a small excavator for loosening grapevine roots and maintaining winter drainage systems
Transformation plan: Selected HW10-3E electric micro excavator (bucket capacity 0.025m³) to replace traditional diesel models
Implementation effects:
Daily power consumption of a single device is only 12 kWh (approximately $0.25 AUD according to local electricity prices)
Soil disturbance accuracy increased by 40%, and grapevine damage rate reduced by 15%
Annual comprehensive savings: Fuel cost 18,000 AUD + maintenance cost 9,000 AUD = $27,000 AUD
Compliant with Australia's Renewable Energy Target (RET), eligible for government carbon tax reduction subsidies
IV. Five reasons to choose Shandong Hengwang
Leading technology: Passed ISO/CE certification, with over 200 patented technologies
Full-scenario coverage: Available in full range from HW-08 (2-ton class) to HW-35 (3.5-ton class)
Green qualifications: Awarded as a national high-tech enterprise and a civilized unit in the national machinery industry
Worry-free after-sales: Provides 3-year warranty + nationwide warranty service
Customized solutions: Supports quick switching of over 20 types of accessories such as breakers and rotary drills
Conclusion
Driven by both environmental policies and economic benefits, eco-friendly mini excavators have become an inevitable choice for engineering equipment upgrading.
