With an operating weight of 21,900 kg, it is equipped with a high-torque 150 kW PMS motor that delivers the brute force necessary to tackle the toughest materials . Engineered for maximum uptime, this machine is designed to lower your total cost of ownership by eliminating fuel costs and reducing maintenance intervals. Built for harsh environments, its reinforced boom and arm allow for continuous operation under heavy loads.
Why Choose This Machinery
In the landscape of heavy equipment, the transition to electric must be driven by ROI, not just regulations. The 21.9-ton Electric Digger offers a distinct competitive edge.
Zero Emissions, Maximum Profitability
Operate in emission-restricted zones and indoors without penalties. The fully electric powertrain ensures zero fuel consumption, drastically reducing daily operating costs and insulating your fleet from volatile diesel prices . Lower operating temperatures also reduce wear on hydraulic components.
Unmatched Durability
Utilizing a platform designed for heavy-duty use, the machine features a robust undercarriage with high ground clearance and a reinforced frame. It shares key structural components with our diesel models, ensuring the same longevity and serviceability you expect from an OEM-grade supplier .
Global Shipping & Warranty
We are experts in global logistics, offering flexible RoRo and Container shipping to major ports worldwide. This electric excavator comes with a comprehensive 1-Year Global Warranty and access to our global spare parts network, ensuring your investment is protected and supported locally.
Powertrain & Structural Overview
The powertrain is the heart of this electric digger, featuring a PMS motor generating 150 kW at 1800 rpm and a massive 1500 Nm of torque . This delivers the high breakout force required for hard digging, closely matching the performance of conventional diesel units. The DOMCS intelligent control system optimizes hydraulic flow, providing smooth, responsive multi-function operation.
Structurally, the upper structure and boom assembly are constructed from high-tensile steel to resist bending and fatigue in rocky applications. The electric drive eliminates engine vibration, enhancing cab comfort and reducing operator fatigue. With a high-flow hydraulic system (2 x 220 LPM), work cycles are faster and more efficient .
Technical Specifications
Below is the primary data for the 21.9 Ton Electric Digger. These parameters ensure precision in procurement and compatibility with your operational requirements.
Heavy-Duty Application Scenarios
Mining & Quarrying
Concrete strength and zero emissions make this electric excavator ideal for aggregate production, ore handling, and overburden removal at quarry sites. Its traction force of 215 kN ensures stability on loose terrain .
Large-Scale Earthmoving
Whether preparing foundations for industrial complexes or handling bulk materials at ports, the 1.2-1.5 m³ bucket capacity ensures high productivity per cycle. The electric motor provides consistent torque, enabling efficient loading of ADTs and dump trucks.
Urban & Infrastructure Projects
With near-silent operation and zero localized emissions, this machine is perfect for urban development projects, underground construction, and night-time works where noise regulations are strict.
Equipment Q&A
Q1: What is the estimated shipping lead time for international orders?
Our standard lead time for the 21.9T Electric Digger is approximately 30-45 days from order confirmation. We have a dedicated logistics team to arrange RoRo shipping or 40ft container shipping to major ports like Houston, Rotterdam, or Singapore. Expedited shipping options are available for urgent project needs.
Q2: What is the average operating runtime on a full charge?
Depending on the application and intensity of work, the runtime is optimized for approximately 7-8 hours of heavy-duty operation. The machine utilizes a high-capacity battery system designed to support a full shift in most demanding scenarios .
Q3: Does the unit include charging equipment, and are the wears parts easy to source?
Yes, the package includes the primary charging unit and cables. We strongly recommend procuring the genuine wearing parts package (bushings, pins, hydraulic filters) alongside the machine to ensure immediate availability when the first service interval is due. We maintain a global spare parts inventory for rapid deployment to minimize your downtime.
Q4: How does this electric excavator perform in cold environments?
This electric digger is engineered to operate in a wide range of climates, performing reliably in temperatures as low as -15°C. The battery management system and electric components are protected against cold-weather challenges, ensuring consistent starting power and hydraulic performance.
Q5: Are there repowering options available for older diesel models?
Yes, for fleet managers looking to transition to electric, we offer repowering solutions. By removing the internal combustion engine components and retrofitting the electric motor and control systems, we can extend the life of your existing capital . Please contact our sales team for a consultation on repowering specific serial numbers.
