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.
1. Core Upgrade & Product Advantages
1.1 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
1.2 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
1.3 UItra-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.
1.4 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, fiexible to match various complex sites and last-mile transport routes
Compatible to splice with standard 3m -width SYV- modules by replacing conecting connectors, greaty lowering customers equipment ivestment cost.
1.5 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.
