Conversion Kit for warehouse tuggers tractors
Since 1995, GREEN MOTOR TECH has specialized in electric vehicle powertrain systems, electric utility vehicles, and customized low-speed industrial mobility solutions.
This project is developed for a 1.5–2 ton standing-type warehouse towing tractor, designed for logistics parks, warehouses, factories, airports, and industrial material transportation applications.
The tractor uses a 2200W 48V DC drive motor combined with a compact transaxle assembly to provide:
The integrated transaxle structure simplifies chassis installation and reduces drivetrain complexity for prototype development.

DC-DC converter typically falls into three voltage levels: low voltage platforms such as 48V and 72V, which are suitable for light-duty equipment and offer advantages in cost and safety but are limited in power output; medium voltage platforms including 96V, 144V, and 192V, which represent the mainstream solution and are widely used in applications such as baggage tractors, belt loaders, and small service vehicles; and high voltage platforms ranging from 300V to 600V or higher, typically used in aircraft tow tractors, large loading equipment, and high-demand systems such as GPU and air conditioning units, offering higher power capability and efficiency but with increased system complexity and cost.
We provide a full range of voltage platforms from 48V, 72V, 96V, 144V up to high-voltage solutions, allowing customers to select the most suitable configuration based on power requirements. Once the voltage and power level are defined, we further optimize the complete system architecture, including components such as DC-DC converters and other key parts, ensuring a fully matched and reliable electrification solution for each application.
In airport Ground Support Equipment (GSE) electrification projects, the power requirement typically ranges from low to high power depending on the application. For towing equipment, power demand includes baggage tractors (5–15 kW), cargo tractors (10–30 kW), and aircraft tow tractors (50–200+ kW). For loading equipment, belt loaders usually require 5–20 kW, while container loaders operate in the range of 20–60 kW. For service equipment, ground power units (GPU) typically require 30–120 kW output power, and air conditioning units range from 20–80 kW.
Our solutions cover a wide power spectrum from 5 kW to 65 kW and are compatible with different voltage platforms such as 48V, 72V, 96V, and 144V. Based on the selected power level, we provide a fully matched system configuration, including motor, controller, battery system, and auxiliary components. The instrument system supports CAN communication with the controller, and can also integrate with the customer’s original dashboard. In addition, we can provide a dedicated compact battery state display to ensure clear and reliable real-time monitoring of system status.

Advantages include:
The customer required a compact and reliable electric drive system for a low-speed towing tractor with the following targets: Towing capacity around 1.5–2 tons Compact standing-type chassis High torque at low speed Lithium battery powered Easy integration for prototype development Complete wiring system for first sample build GMT supplied a complete electric drivetrain package including motor, transaxle, controller, battery system, charger, steering components, and wiring harness.
GMT supplied:
This configuration improves installation efficiency and ensures stable traction performance for warehouse floor conditions.
For the first prototype stage, GMT supplied:
Because prototype projects require flexible electrical layouts, the initial harness was produced manually for rapid development and testing.
For mass production, the harness can be converted into batch manufacturing with standardized connectors and optimized production processes.
The first prototype includes:
GMT supports customers during prototype engineering stages by providing customized steering structures suitable for compact industrial vehicles.
This electric towing tractor drive solution is suitable for:
GREEN MOTOR TECH provides:
We support:
With over 20 years of EV manufacturing experience, GMT focuses on reliable quality, stable performance, and practical electric mobility solutions for global customers.
Yes, we provide all electronic parts for conversion. We also provide wire diagram system, each part user manual, so you will have no obstacles for installation and connection of the system.
Yes, we provide motor spline coupler and adapter plate to install motor to original transmisison. But the original transmission’s clutch need to get removed. If you want to keep clutch, you need modify the spline coupler to clutch a bit. Because we do not have car in hand, so we bought a old transmission without clutch to make the coupler and adapter kit.
We provide two years for battery, and one year warranty for other parts. We only use top grade quality products. If any parts failure from manufacturing issues, we provide repair parts for replacement.
If we have stocks ready to go, the lead time is one weeek after order confirmed. if we have no stocks, lead time might be 4 weeks after order confirmed.
After you have discussed with sales manager all details of the order, he or she will make proforma invoice with all details and bank accounts for payment, normally payment is through bank to bank T/T. Other payment ways are also flexible to accept after discussion.
We only use top brand of cells in China, like EVE, like Gotion etc, most of the case we use EVE brand pure new and A grade cells to make pack. And in our battery pack we surely use real automobile grade BMS, not simple protection board.
We care about reputation more than our customers!
We are real manufacturer, not sales trade office/company, we started our motor production from 1995 in China. In conversion we now have more than 10 year experiencee. In the whole drive systems, we do not produce all parts, but motor we make, controller we provide CAN BUS and technical requests to our partner, same as lithium battery pack and wire hanress of the system, the design and CAN BUS are from us. other accessories like gas peda, meter etc we get from reliable partners.
Except motor and drive train solution, we also owns our own low speed electric vehicle assembly factory, its website/brand is www.gmtlsv.com
In short, we are EV expert with decades experience in China!
Yes, our key electronic components are with CE certificate for Europe markets, so at the moment, we ship to Europe like France, UK, Germany, Italy, Sweden, Belgium, Turkey etc.
We also have ISO9001 quality manage certificate.
For our EV products, we also have WMI (World Manufacturer Identifier) certificate, each vehilce has its VIN number.
To some particular countries, they have requests in import or tax reduces policy such as for Africa countries and Middle East, COC or SABER might needed for import. For some countries, certificate of origin: FORM A, FORM E etc are requested. We all have experience to make for customers.
Yes, of course, our engineers who can speak English directly, video talk/email/Whatsapp they can communicate and serve customers without obstacles.
No matter before-sales or after sales, we all request in time response 24 hours and 7 days as long as we see the requests.
For necessary project, we can also send engineers to customers’ company for guide or training.
We also welcome customers to send engineers to us for onsite learning and training!
Yes, no problem, we support that. We hope customers can do longterm business so customization of his logo is OK
