Engineered to maximize efficiency, loading capacities, and safety metrics for critical ramp and runway operations.
The global aviation ecosystem demands rapid aircraft turnaround times, rigorous safety standards, and strict adherence to decarbonization protocols. Aircraft ground support equipment (GSE), specifically aircraft towing tractors, serves as the operational anchor of this workflow. As a leading manufacturer and supplier based in China, we leverage state-of-the-art engineering to supply highly reliable towbarless and conventional aircraft tractors designed to mobilize widebody and narrowbody commercial aircraft.
Our towing tractors are designed around the physics of Drawbar Pull (DBP). Tractive force calculation must account for wet ramp coefficients of friction, aircraft operational weights, tire wear, and runway grades. By employing integrated smart engine and motor controllers, our tractors (CDT series) optimize torque distribution in real-time, preventing wheel slippage while preserving drivetrain longevity.
The aviation industry is aggressively targeting carbon neutrality. Our product engineering pipeline has adapted to this green transformation through a multi-tiered technological roadmap:
Airports are not just parking spaces; they are complex logistics nodes. A towing tractor cannot work in isolation. Our engineering strategy targets complete compatibility with other ground vehicles, ensuring seamless integration between GSE assets like baggage tow tractors, aircraft refuelers, cargo loaders, and mobile ground power units (GPUs).
By coordinating communication protocol standards (such as CAN bus J1939), our ground equipment integrates into larger airport fleet management systems. Fleet managers can track vehicle locations, engine diagnostic trouble codes (DTCs), fuel/energy usage, and towing statistics automatically, minimizing operational downtime.
Operating a high-tech manufacturing plant in China provides distinct advantages for global airport procurers. Through our optimized vertical integration, we control the production cycle from raw raw steel fabrication to complex electronic assembly:

A deep dive into our manufacturing methodologies, certification compliance, and global logistical support capabilities.
Global airline alliances (Star Alliance, SkyTeam, Oneworld) and international ground handling agents (e.g., Swissport, Dnata, Menzies) maintain rigorous procurement standards. When sourcing from China, standard compliance is the primary gatekeeper. Our engineering team ensures all units conform to:
Our aircraft towing tractors (CDT series) utilize interchangeable towbar couplers to service various passenger aircraft types, including the Airbus A320/A330/A350 series and Boeing 737/777/787 models. This versatility minimizes the capital expenditure needed by local ground handling agencies.
Procuring ground equipment from China is only the first step; maintaining maximum uptime throughout a 15-year service life requires localized support. We mitigate maintenance risk through a structured service network:

Technical answers to common engineering, procurement, and deployment questions regarding airport towing tractors and dollies.
Conventional tractors use a calibrated towbar attached to the plane's nose landing gear, directing the aircraft via shear-pin couplings. Towbarless (TBL) tractors scoop up the nose wheel directly, holding it within an integrated hydraulic cradle. TBL units allow faster pushback speeds, better ramp safety, and eliminate the risk of towbar shear-pin breakages during tight turnarounds.
Required Drawbar Pull is calculated using the formula: DBP = W * (a/g + r + g_grade), where W is the gross aircraft weight, a is the desired acceleration rate, r is the rolling resistance coefficient (typically 0.015 for concrete), and g_grade is the slope gradient percentage. Our CDT700, for instance, supplies up to 450 kN of tractive force to manage widebody aircraft on wet, inclined ramp configurations.
We primarily utilize high-density Lithium Iron Phosphate (LiFePO4 / LFP) battery systems. LFP offers excellent thermal stability, safety under mechanical shock, a long life cycle exceeding 3,000 charges, and rapid opportunity charging capabilities, making it ideal for the continuous operation cycles of busy airports.
Our cargo dollies undergo rigorous welding quality protocols. We employ robotic welding workstations to ensure penetration uniformity, followed by ultrasonic non-destructive testing (NDT) on critical load junctions. Standard hot-dip galvanization is applied to protect the structural steel from runway de-icing chemical corrosion.

How towable battery packs are changing aircraft gate operations, offering zero-emission, silent 400Hz power to auxiliary systems without the need for diesel fuel or permanent grid connection upgrades.
In the complex ecosystem of aviation operations, ensuring an aircraft is flight-ready involves a multitude of support systems. Among the most critical components in this pre-flight preparation is the Aircraft Ground Power Unit (GPU). These units supply the essential electrical power required for aircraft while parked on the ground, facilitating system checks, pre-flight preparations, and passenger boarding without the need to run the aircraft's main engines. While GPUs come in various forms, truck-mounted solutions have emerged as a particularly versatile and efficient choice for modern airports and maintenance facilities.
Our mission is to make their choices firm and correct, to create greater value for customers and to realize their own value.
