1. Product Overview
The SYV-8 3.2m widened hydraulic modular semi-trailer is upgraded based on our mature and proven classic model, which is professionally customized as integrated heavy haul equipment for large-scale oversized cargo transportation.We focus on three core optimization directions: driving stability, load-bearing performance and overall durability, solving various pain points in heavy transport operation for global customers.
2. Core Upgrade & Product Advantages
2.1 Optimized 3.2m Wide Chassis for Higher Transport Stability
- The standard chassis width is expanded from 3m to 3.2m, with an extra 20cm width.
- Effectively reduce the risk of gravity center offset during transportation.
- Deliver excellent stability under full heavy load and running operation.
2.2 Upgraded Tires for Stronger Load & Impact Resistance
- Original 215-series tires are replaced with upgraded wide-section tires.
- Larger ground contact area greatly improves impact resistance.
- Suitable for summer high-temperature environment, unpaved construction roads and overloaded transportation.
- Efficiently cut the cost caused by tire blowout and daily maintenance.
2.3 Ultra-Low Deck Height Design
- Strictly controlled minimum vehicle deck height: 8 units, only slightly higher than standard 3m-width models.
- No negative impact on regular loading, unloading and passing through height-limited road sections.
2.4 Flexible Modular Combination Structure
- Single module supports free combination of 2/3/4/5/6 axles as per actual transport demands.
- All modules are mass-produced with standardized parts, flexible to match various complex sites and last-mile transport routes.
- Compatible to splice with standard 3m-width SYV-8 modules by replacing connecting connectors, greatly lowering customers’ equipment investment cost.
2.5 Premium Imported Full Hydraulic System
- Adopt high-performance ball valve hydraulic control valves.
- All quick connecting plugs and hydraulic hoses are imported from world top-tier brands.
- Stable, leak-free and reliable long-term operation under continuous heavy load.
