View SpecificationsThe continuous growth of global air transport requires airports to process air cargo at unprecedented speeds. Historically, airports relied on single Unit Load Device (ULD) transport mechanisms. However, ramp congestion, fuel costs, and turnaround limits have shifted demand toward dual-capacity models. The Double LD3 Container Dolly represents a milestone in engineering, allowing ground operators to tow two standard LD3 (IATA type AKH, AKE, or equivalent) containers simultaneously without extending the turning radius or compromising safety protocols.
This dual-transport layout matches the physical dimensions and structural configurations of common commercial aircraft belly holds, such as the Boeing 777, 787, and Airbus A350, A330. By enabling a single ground service vehicle to haul twice the volume, airport authorities decrease the total number of motorized GSE trips required per flight. The structural dynamics of our double LD3 dollies incorporate a high-rigidity chassis, dual-rotation turntables, and heavy-duty towbar mechanisms designed to handle heavy cyclic stress under adverse weather conditions.
At our manufacturing hubs, custom double LD3 container dollies undergo finite element analysis (FEA) testing to guarantee performance under maximum load conditions. Precision engineering ensures that the dolly remains balanced and responsive, whether navigating narrow taxiways or high-velocity cargo transfer zones.
| Specification Parameter | Standard Model Configuration | Custom Heavy-Duty Variation |
|---|---|---|
| Nominal Payload Capacity | 3,200 kg (7,054 lbs) | Up to 4,500 kg (9,920 lbs) for heavy cargo hubs |
| Chassis Structure | Hot-dip galvanized structural carbon steel | Reinforced high-tensile steel with anti-corrosion coating |
| Roller Bed Configuration | Galvanized rollers with precision sealed bearings | Self-lubricating, shock-absorbent composite rollers |
| Brake System | Towbar-activated parking brake (front wheel locking) | Dual-action mechanical brake with redundant lock sensors |
| ULD Security Lock | Gravity-activated flip locks (manual release) | Pneumatic or spring-assisted quick-lock assemblies |
| Tire Specifications | Solid rubber tires (4.00-8 or 15x41/2-8) | Puncture-proof polyurethane or heavy-duty press-on band tires |
Each dolly features a continuous turntable layout with self-aligning bearings, ensuring that the ULD containers can rotate 360 degrees for alignment with cargo loading belts. The heavy-duty towbar incorporates a dampening system that reduces impact force on the tow tractor during deceleration. Side guides protect the dolly structure from direct impact by forklifts and ground operations equipment.
Global airport operators and cargo handling agencies evaluate GSE procurement based on Total Cost of Ownership (TCO), component standardization, and regional regulation compliance (such as OSHA, CE, and IATA guidelines). Sourcing custom double LD3 container dollies requires a deep understanding of terminal operating conditions:
Sourcing custom aviation equipment from Chinese manufacturers has transitioned from simple cost-reduction strategies to a focus on advanced production quality and supply chain reliability. Our factories utilize robotic welding cells, automated plasma cutting tools, and modern sandblasting chambers to ensure high precision across all production stages. This industrial foundation guarantees that every dolly matches the strict structural requirements of busy airport operations.
We provide comprehensive support for custom OEM and ODM requirements. Whether an airline requires specific locking mechanisms, unique dimensions for cargo holds, or specialized towbar systems, our design and engineering team works closely with clients to deliver optimal results. From initial concept generation and finite element analysis to prototype testing and mass production, we provide an integrated manufacturing workflow that reduces time-to-market while maintaining strict control over component quality.
Additionally, our proximity to component supply chains ensures fast access to raw materials and specialized hardware, providing clear advantages in lead times and production adaptability. This localized industrial framework allows us to meet urgent fleet expansions or customize small-batch orders with high precision.
Airport ground environments vary significantly depending on geographic location. Our double LD3 container dollies are designed to operate reliably under extreme conditions, including freezing northern regions, high-humidity coastal zones, and high-altitude cargo hubs.
In sub-zero conditions, runways are treated with chemical agents that can accelerate rust and degrade components. To prevent structural damage, our dollies are hot-dip galvanized according to ISO 1461 standards, protecting all welded joints and inner frame structures. Seals and bearing grease are selected to maintain flexibility and protect components at temperatures down to -40°C. For coastal terminals, stainless steel axles and marine-grade protective coatings are available to guard against high humidity and salt spray exposure.
We manufacture and supply a full range of aviation support units, ensuring compatibility across different operations. Explore our specialized equipment categories below:
