Ultra-Long Boom Heavy-Duty Crane Truck | Full Factory High Specification

This SINOTRUK HOWO 6x4 rear eight-wheel crane truck is a newly upgraded heavy-duty integrated lifting and transportation vehicle, perfectly built for high-altitude construction, large-scale material handling, municipal engineering, and harsh off-road working conditions. Equipped with Weichai 320HP 6.8L large-displacement power, 12-speed synchronized heavy-duty transmission, 13-ton 3-lock heavy-duty rear axle, reinforced three-layer frame, and top-tier Changxing 14-ton 6-section ultra-long boom crane, this unit delivers stronger power, larger operating radius, higher lifting efficiency and superior overall stability compared with ordinary crane trucks, making it the ideal profit-generating equipment for global engineering contractors.

Power System: Weichai 6.8L 320HP High-Torque Engine

Powered by the genuine WP7H320E62 diesel engine with 6.8L large displacement and 320 horsepower, this power core features abundant low-speed torque and stable continuous power output. It maintains strong dynamic performance under full-load and long-hour high-intensity operation, providing excellent climbing ability and terrain adaptability. It easily copes with mountain roads, muddy construction sites and long-distance heavy transportation, achieving a perfect balance of powerful performance and low maintenance costs.

Transmission & Professional PTO System

Matched with HW13709XSTC2 12-speed heavy-duty synchronized transmission and original HW70 flange-type power take-off (PTO). The professional integrated powertrain realizes smoother gear shifting, stronger impact resistance and higher power transmission efficiency. The stable flange PTO provides continuous and sufficient hydraulic power for the crane system, ensuring sensitive response and flexible compound lifting actions without power attenuation, greatly improving overall construction efficiency.

Heavy-Duty Chassis, Axle & Structural Configuration

Built for extreme heavy-load durability and stability, the chassis adopts a 8+5+5mm three-layer integral through frame (300mm height) with ultra-high torsion and deformation resistance. It is equipped with heavy-duty 10/12 multi-leaf springs, four-bolt fixing structure and V-type thrust rod, effectively stabilizing the vehicle body under bumpy and heavy-load conditions.

Key Chassis Parameters

Wheelbase: 5800+1350mm
Gear Ratio: 5.29 (optional 4.63 / 4.11) for flexible speed and torque matching
Axle Configuration: 7.5-ton reinforced front axle + 13-ton heavy-duty rear axle with 3 differential locks
Tires: 11.00R20 18PR mixed-pattern heavy-duty tires, wear-resistant and anti-skid for complex road conditions

The 13-ton three-lock rear axle provides powerful torque amplification and excellent off-road passability, easily overcoming steep slopes, muddy roads and rugged construction terrains.

TX-J Half Row Luxury Cabin | Safety & Comfort

Adopting authentic German MAN technology cabin with four-point suspension damping and advanced crash energy absorption technology, it maximally protects driver safety in emergencies. The cabin is equipped with an ergonomic airbag main seat with waist support, auxiliary seat and middle spare seat. Standard configurations include multifunctional steering wheel, electric adjustable & heated rearview mirrors, ABS safety system, manual & electric integrated cab lifting, 300L aluminum alloy fuel tank, 165AH battery and SINOTRUK intelligent management system, bringing long-lasting comfortable and safe working experience.

Core Lifting System: Changxing 14Ton 6-Section Ultra-Long Boom Crane

Fitted with genuine Changxing 14-ton 6-section straight boom crane, the top configuration for medium and large tonnage lifting operations. It supports upper operation, second-arm independent control, dual slewing mechanism, dual-stage hydraulic outriggers, built-in radiator and automatic hook retraction function. Reinforced full subframe and 8.4m heavy-duty cargo box (3-side 5-bottom reinforcement) ensure ultra-high structural stability.

Superior Lifting Performance

Max Boom Length: 22.6m
Ultra-large working radius & high lifting height
Stable hydraulic output, precise positioning and low failure rate

Perfect for high-rise installation, overhead line construction, large steel structure handling, tree transplantation and large-scale municipal lifting projects, covering all complex high-altitude and heavy-load operation scenarios.

Product Core Advantages

This HOWO 6x4 crane truck adopts factory integrated engine, transmission and axle matching design with higher vehicle compatibility and lower failure rate. With 320HP strong power, 12-speed synchronous gearbox, three-layer reinforced frame, 3-lock off-road axles and 22.6m ultra-long 6-section boom, it integrates heavy cargo transportation and ultra-high-altitude lifting functions. It is a high-cost-performance, super-durable and multi-scenario heavy-duty engineering vehicle for global construction fleets.
