ZW-Trailer Self-Propelled Modular Transporter (SPMT) Trailer transportador modular autopropulsado

Heavy-Duty Modular Transport Solution for Ultra-Heavy and Oversized Cargo Handling

What Is an SPMT Trailer?

A Self-Propelled Modular Transporter (SPMT) is a modular platform vehicle equipped with its own drive, steering, and hydraulic lifting system. Unlike conventional trailers, SPMTs can move independently, rotate 360 degrees, and be connected in multiple configurations to create extremely large transport platforms.

ZW Group SPMT trailers are designed to meet the most demanding heavy transport requirements, supporting both line configuration and side-by-side combination, making them ideal for ultra-heavy transport projects worldwide.

Key Features of ZW Group SPMT Trailer
1. Modular Design for Unlimited Combinations

ZW Group SPMT trailers feature a modular structure, allowing multiple axle lines to be connected longitudinally or laterally. This flexible design makes it easy to customize the system for different cargo sizes and weights, from 100 tons to over 10,000 tons.

2. High Load Capacity per Axle Line

Each axle line of the ZW Group SPMT can support extremely high loads, making it suitable for heavy-duty transportation of transformers, wind turbine components, refinery modules, ship sections, and mining equipment.

3. Advanced Hydraulic Suspension System

The independent hydraulic suspension system provides:

Automatic load equalization

Precise height adjustment

Excellent stability on uneven ground

Smooth lifting and lowering of cargo

This ensures safe transport even under complex road conditions and construction environments.

4. Multi-Mode Steering System

ZW Group SPMT trailers support multiple steering modes, including:

Front steering

Rear steering

All-wheel steering

Crab steering

Carousel (360° rotation)

This enables exceptional maneuverability in tight job sites, ports, factories, and construction zones.

5. Powerful Power Pack Unit (PPU)

Each SPMT system is equipped with a reliable diesel power pack unit, providing strong driving force, stable hydraulic power, and continuous operation under extreme conditions. ZW Group offers PPUs with internationally recognized engines such as Cummins, Deutz, or customer-specified brands.

6. Intelligent Remote Control System

The SPMT is operated via advanced wireless remote control, allowing precise movement, synchronization, and monitoring. Operators can easily control speed, steering, lifting, braking, and synchronization between multiple units.

7. High Safety Standards

ZW Group SPMT trailers are built with multiple safety systems:

Emergency stop system

Overload protection

Hydraulic pressure monitoring

Real-time fault diagnosis

Anti-slip braking system

Redundant control system

These features ensure safe operation in critical heavy transport projects.
