1. Cab & Safety Technology
The HOWO TX adopts the TX7 German MAN luxury cab with 4-point floating suspension system, which greatly reduces bumpy vibration on rough construction roads and provides drivers with a comfortable working environment even during long-hour shifts.
Most importantly, it is equipped with life-protection cabin collapse technology — the cab slides backward in case of a frontal collision to absorb impact energy and protect the driver. This is a critical safety feature for heavy construction vehicles working under high-load conditions.
2. Multi-Engine Power Options (Weichai & German MAN)
HOWO TX provides three power configurations to match different budget and working intensity needs:
-
Weichai 240 HP (WP4.6NQ240E62) — Cost-effective choice for daily 8–10 ton lifting work
-
Weichai 270 HP (WP7H270E62) — Balanced power for frequent muddy slopes and heavy loads
-
German MAN 290 HP — Top-tier configuration for all-day continuous heavy-duty operation
All engines deliver strong low-speed torque output, ensuring stable traction when starting with full loads on muddy slopes, no slipping or stalling on rough site roads.
3. Transmission & Heavy-Load Axle System
Matched with HOWO 8-speed or 12-speed gearbox with synchronizer, the shifting is smooth and precise, with maximum transmission torque up to 1200 N·m. This ensures power is delivered efficiently even under full 12-ton lifting conditions.
The axle configuration is the core advantage of this chassis: 7.5-ton front axle + 13-ton reinforced rear axle. The 13-ton rear axle has the strongest load capacity in the single-axle industry, making it the absolute best choice for installing 12-ton cranes without overloading concerns.
4. Triple-Layer Frame & Engineering Suspension
Built with triple-layer frame structure (8+4+4 / 302mm), the overall torsional rigidity is far superior to ordinary double-layer frames. Long-term heavy lifting on bumpy roads will not cause frame deformation or cracking, ensuring a long service life of 10+ years.
Equipped with 11/9+8 engineering grade leaf springs, the load-bearing and shock absorption performance are specially optimized for construction sites. It handles potholes, muddy roads and uneven terrain with stable body posture, protecting both the crane equipment and the chassis structure.
5. Interior Comfort & Intelligent Management
The cab comes with multi-function steering wheel and 10.1-inch large central control screen, providing convenient operation and clear vehicle status display. Electric adjustable & heated rearview mirrors ensure clear vision in rainy, foggy and high-humidity tropical environments.
The SINOTRUK Intelligent Connect system allows real-time remote monitoring of vehicle status, fault diagnosis and maintenance reminders. Fleet managers can track all trucks from the office, reducing downtime and maintenance costs.
6. Official Certification & Modification Advantages
Three official announcement models cover different modification needs:
-
ABC5180JSQZZ6 — Supports flatbed with ladder and knuckle boom crane installation
-
ABC5181JSQZZ6 — 12.8T curb weight, XCMG 12-ton crane fits without overweight issue
-
ABC5186JSQZZ6 — Special certification for Weichai 270 HP engine configuration
As the top-selling crane truck chassis in the Chinese market, the HOWO TX single-axle chassis has mature modification compatibility with all major crane brands (SANY, PALFINGER, XCMG). It is the most cost-effective heavy-load choice for 10–12 ton lifting equipment, widely trusted by construction contractors worldwide.
