Multi‑Axle Hydraulic Modular Trailer

JUTONG Engineering‑grade extreme heavy‑haul modular transport vehicle purpose‑built for oversized, indivisible super‑heavy cargo transportation. Composed of multiple interchangeable axle‑line modules, this hydraulic modular trailer supports longitudinal and lateral module combination to adjust platform dimension and total bearing capacity.

Every axle‑line module adopts independent hydraulic suspension and multi‑mode full‑wheel steering. Hydraulic lifting stroke, steering system, power pack and load‑fixing accessories can be configured to comply with diverse national heavy‑haul standards. No standard fixed specifications are available. Overall scheme is engineered according to cargo weight & dimension, prime‑mover parameters, site space, local legal axle‑load restrictions and actual road conditions.

Power‑Energy Project Logistics: Transporting large‑size transformers, generator stators, wind‑turbine components and power‑station equipment between factory yard, port and remote project sites.

Petro‑Chemical Heavy‑Haul: Deployed by professional heavy‑lift contractors for reactors, heat exchangers and other oversized process equipment delivery for refinery and chemical plant construction.

Bridge & Civil‑Infrastructure Transport: Moving pre‑cast bridge girders, tunnel‑boring‑machine segments and large steel structural components for road, railway and municipal projects.

Heavy‑Industry Factory Relocation: Optimised for transporting heavy mill housings, large forging equipment and non‑divisible industrial machinery across mixed highway and narrow‑access work‑site routes.

Modular Combined Platform Structure

• Flexible Module Splicing: Individual axle‑line modules can be assembled longitudinally or laterally to obtain required platform length, width and total payload without fixed single‑unit dimension limits.

• Height‑adjustable Hydraulic Deck: Independent hydraulic suspension provides ±300mm lifting travel for platform height adjustment, adapting to bridge clearance, ramp loading and uneven ground surfaces.

• Modular Components: Axle‑line quantity, power‑pack layout and auxiliary bolsters are finalised according to cargo outer dimensions and project constraints.

Super‑Heavy Load Distribution Performance Oversized indivisible heavy‑weight equipment brings huge concentrated point loads, requiring multi‑point uniform load distribution and outstanding frame anti‑deflection performance while travelling over uneven road surfaces.

Evaluated design parameters include: Total cargo weight and overall outer dimension Cargo gravity centre and supporting contact footprint Axle‑line combination layout and local legal per‑axle‑line load limits Hydraulic suspension performance plus main‑beam structural rigidity Practical road condition, bridge load‑rating and overhead height‑restriction rules

Multi‑Mode Full‑Wheel Steering Control

• Path‑Tracking Management: Every axle line achieves independent hydraulic steering, minimising off‑tracking for long multi‑module heavy combinations.

• Multiple Steering Modes: Normal highway steering, crab‑steer (side‑shift movement), central rotation steering for confined‑space site operation.

• Improved Maneuverability: Greatly enhances passing performance on narrow roads, sharp bends and compact project‑site access zones.

Hydraulic & Electronic Control Integration

• Specialised Operational Functions: Integrated hydraulic circuits for platform lifting‑lowering, all‑wheel steering and module locking connection.

• System Components: Hydraulic power unit, manifold valve blocks and suspension cylinders are selected to adapt long‑time heavy‑load and dusty field‑working environments.

• Service‑Oriented Design: CAN‑bus fault‑diagnosis system supports quick on‑site troubleshooting; core components keep high compatibility with mainstream global heavy‑haul modular trailer fleets.

Super‑Heavy Cargo Interface & Load‑Securing Layout

• Multi‑point Load Transfer Design: Massive reinforced lashing anchor‑points and stake pockets disperse huge tension force generated during bumpy‑road transit.

• Custom‑fabricated Auxiliary Supports: Saddle bolsters, load spreader beams and special adapter frames are engineered for specific heavy‑equipment profiles.

• Pre‑Production Verification: Overall modular combination scheme is cross‑checked via load‑simulation calculation before manufacturing commences.

Steel Preparation: High‑strength quenched & tempered structural steel plates cut by CNC plasma equipment for precise dimensional accuracy.

Structural Welding: Main box beams, cross‑members and module connecting sections adopt heavy‑duty robotic submerged‑arc welding procedures.

Dimensional Inspection: Critical frame segments, module‑joint interfaces and mounting positions receive full dimensional verification before assembly.

Hydraulic‑Steering Calibration: Each axle‑line steering angle and hydraulic suspension lifting synchronism are precisely calibrated.

System Comprehensive Testing: All hydraulic circuits, steering actions, wireless remote‑control and safety interlock logic complete full‑cycle pressure‑holding & functional testing prior to shipment.
