Run Your Existing Excavator on Electric Power — Without Giving Up Diesel Mobility
Excavators are among the most important machines in construction, infrastructure, mining, ports, scrap handling, bulk material handling and industrial applications. But for machines operating for long hours at a fixed or semi-fixed location, diesel fuel can become one of the largest components of operating cost.
To address this challenge, Servoday Plants & Equipments Limited has introduced a Retrofit Electric Excavator System that converts a conventional diesel crawler excavator into a dual-power excavator capable of operating on both electric power and diesel.
The concept is simple:
Electric when the excavator is working at a fixed location.
Diesel when the excavator needs mobility.
This approach allows owners to reduce diesel consumption while retaining the original mobility and flexibility of the excavator.
Why Convert a Diesel Excavator to Electric?
A conventional diesel excavator can consume a significant quantity of fuel during long operating hours. This becomes particularly important in applications where the machine remains in one working zone for most of the day.
Typical examples include:
When the machine is working continuously at one location, repeatedly running a diesel engine may not always be the most economical operating arrangement.
A properly engineered electric retrofit can allow the hydraulic system to be powered by an electric motor while the diesel engine remains available for travelling and applications where electrical power is not available.
Dual-Mode Operation: Electric + Diesel
The major advantage of our retrofit concept is that the machine does not have to become electric-only.
The excavator can be configured for:
1. Electric Mode
The hydraulic system is powered by an electric motor.
This mode is suitable for long-duration operation at a fixed or semi-fixed workplace.
2. Diesel Mode
The original diesel engine remains available for machine movement, relocation and areas where electric power is unavailable.
3. Electric + Diesel Flexibility
The owner therefore gets the flexibility of two operating modes from one excavator.
Work continuously on electricity where power is available.
Move the machine using diesel when required.
Fuel Saving Up to 65% — Application Dependent
Our retrofit system is designed to substantially reduce diesel consumption when the excavator is operated in electric mode.
Fuel saving can be up to approximately 65% compared with conventional diesel operation in suitable applications.
Actual savings depend on:
Therefore, the actual saving should be established through a machine-specific energy and operating-cost calculation before installation.
Easy Return on Investment
One of the biggest advantages of electric conversion is the possibility of recovering the retrofit investment through operating-cost savings.
The basic calculation is:
Annual Diesel Saving = Diesel Saved per Hour × Operating Hours per Year × Diesel Price
And:
Annual Energy Cost = Electricity Consumption per Hour × Operating Hours per Year × Electricity Tariff
Therefore:
Annual Operating Saving = Diesel Operating Cost − Electric Operating Cost
Approximate payback:
Payback Period = Retrofit Investment ÷ Annual Operating Saving
The more hours the machine operates every day, the greater the potential benefit from electric operation.
For machines working 8, 12, 16 or even 20+ hours per day, the economics can become particularly attractive when electricity is available at a competitive industrial tariff.
A proper site-specific ROI calculation should always be prepared using actual diesel consumption, electricity tariff, machine loading and annual operating hours.
No Need to Send Your Excavator to Our Factory
This is one of the most important advantages of our new retrofit approach.
Traditionally, if a machine has to be transported to a workshop or manufacturer facility for electrical conversion, the customer may have to deal with:
Depending on the machine and scope of work, a conventional factory-based conversion can result in a substantial period during which the customer’s machine is unavailable.
Now We Bring the Retrofit System to Your Site
With our on-site electric excavator retrofit solution, installation can be carried out at the customer’s location using suitable workshop tools and trained manpower.
Our target installation period can be approximately 10 days at site, subject to:
This can potentially eliminate a major portion of the transportation and machine-idle period associated with sending the excavator to a factory.
Your machine stays at your site.
Your machine can return to productive operation faster.
You avoid unnecessary two-way transportation.
You can continue earning from the machine instead of keeping it idle for a long workshop period.
Installation at Your Site
Our retrofit philosophy is based on minimum disruption to the customer’s operation.
The conversion system is engineered around the existing excavator architecture wherever technically suitable.
The installation may include:
The exact design is finalized after inspecting the excavator and understanding its hydraulic system and application.
Standard Cable Harness and Professional Electrical Wiring
A reliable retrofit is not simply about installing a motor.
The electrical system must be properly designed, protected, routed and documented.
Our retrofit package can incorporate a structured electrical wiring system with:
This helps make troubleshooting, servicing and future maintenance easier.
Genuine Electrical Components from Established Brands
Depending on availability, voltage, motor rating, VFD selection and project requirements, the retrofit can be engineered using established industrial electrical brands such as:
Switchgear & Protection
VFD / Motor Drive
Motors
Depending on application and rating:
Control Components
The final component selection depends on the electrical rating, machine configuration, environmental conditions, availability, service support and customer specification.
VFD-Controlled Electric Drive
The electric motor can be controlled through a suitable Variable Frequency Drive (VFD).
The VFD allows controlled adjustment of motor speed according to operating requirements.
Benefits may include:
The operating RPM can be adjusted according to the hydraulic system and required performance.
Smooth and Silent Electric Operation
Compared with a diesel engine running continuously, electric operation can provide a significantly different working environment.
The electric mode can offer:
This can be particularly useful in factories, warehouses, ports, scrap yards and industrial premises where noise and exhaust emissions are important considerations.
Electric-Shock Protection and Safety Controls
Electrical conversion must be designed with safety as a primary consideration.
The retrofit system can include:
The machine should be operated only after proper commissioning, insulation testing, earthing verification and safety checks.
Mobility with Trailing Cable
A common concern with an electric excavator is mobility.
Our dual-power concept addresses this by retaining diesel operation for movement where required.
For electric operation, a suitable trailing cable management arrangement can be provided according to the site layout.
Depending on the application, the system can incorporate:
The cable arrangement should always be designed according to machine movement, operating radius, voltage, current and site safety requirements.
Real-Time Excavator Monitoring
An advanced retrofit system can also incorporate IoT-based remote machine monitoring.
The owner can monitor important operating parameters from a mobile phone or authorized remote dashboard.
Depending on the selected monitoring package, parameters may include:
Machine Status
Electrical Parameters
Temperature Monitoring
Safety Monitoring
Mobile Alerts and Remote Notifications
The monitoring system can be configured to send alerts to authorized users.
For example:
Machine Started
Machine Stopped
High Motor Temperature
High Hydraulic Oil Temperature
High Electrical Load
Earth Leakage Detected
VFD Fault
Emergency Stop Activated
Abnormal Voltage
Excessive Current
This gives the owner greater visibility over machine operation without needing to physically stand beside the excavator.
Remote Emergency Stop
Where technically and legally appropriate, the monitoring architecture can also support a remote emergency-stop command.
This feature should be engineered with appropriate safety architecture and must not be treated as a replacement for the machine’s local emergency-stop and isolation systems.
The objective is to provide an additional layer of remote supervision and intervention.
Easy to Install
The retrofit system is designed around a practical field-installation philosophy.
Instead of completely redesigning the excavator, the conversion is engineered around the existing machine wherever feasible.
This can reduce:
Every excavator is different, so a detailed inspection is required before finalizing the retrofit design.
Easy to Operate
The operator should not need to become an electrical engineer to operate the converted excavator.
The control system can be designed around simple controls such as:
The goal is to keep the operator interface simple and familiar.
Easy Maintenance
A well-designed electrical drive system can simplify maintenance by reducing the number of conventional diesel-engine-related service requirements during electric operation.
Electric mode can reduce the need for continuous:
However, the original diesel engine, hydraulic system, undercarriage, swing mechanism and other excavator components still require regular preventive maintenance.
Long Service Life
The retrofit system is designed using appropriately rated industrial components selected for the machine’s operating environment.
Long service life depends on:
The objective is to achieve reliable long-term operation rather than simply installing an electric motor.
High-Speed Cooling Fans
Electrical and control equipment generates heat, particularly in demanding industrial environments.
The retrofit system can therefore incorporate high-performance cooling fans and suitable panel ventilation/cooling arrangements.
Temperature monitoring can also be integrated into the control and monitoring system.
This helps protect:
Suitable for Fixed and Semi-Fixed Applications
Electric conversion is particularly interesting where an excavator spends most of its operating hours in a defined area.
Typical applications include:
Ports & Bulk Handling
Scrap & Steel Industry
Biomass & Renewable Energy
Mining & Aggregates
Waste Management

What We Need Before Quoting a Retrofit
For accurate engineering and commercial quotation, we normally require information such as:
This information helps determine the correct:
Motor kW + VFD rating + electrical panel + cable size + protection system + cooling arrangement + mechanical coupling + monitoring system.
Why Choose a Site-Based Retrofit?
Conventional Approach
Excavator → Transport → Factory → Retrofit → Commissioning → Transport Back → Site
This can involve considerable transportation, downtime and machine-idle costs.
Our Site Retrofit Approach
Excavator remains at your site → Retrofit team arrives → Installation → Testing → Commissioning → Production
This approach can significantly reduce unnecessary transportation and downtime.
The Real Business Benefit
The biggest benefit is not simply replacing diesel with electricity.
The real objective is to reduce the cost of every productive operating hour while retaining the flexibility of a diesel excavator.
You can potentially achieve:
Lower diesel consumption
= A more flexible and potentially more economical excavator
Why Buy a New Electric Excavator When You Already Own a Good Diesel Machine?
If the existing excavator has:
then replacing the entire machine may not always be necessary.
A retrofit can allow the owner to upgrade the power source while retaining the existing machine platform.
This can potentially extend the productive life of an existing excavator while reducing operating expenditure.
