In mining, infrastructure material transportation, and other scenarios, equipment needs high reliability and efficiency. ZW Group’s newly developed 3-axle dump semi-trailer meets these demands.

It has three core traits: strong heavy-load capacity, high unloading efficiency, and all-condition durability. So, it becomes a top solution in engineering logistics.

Core Specifications & Parameters

1. Load-Bearing & Structural Design: High-Strength Build for Heavy Loads

It adopts 3 heavy-duty special axles. Each axle has a rated load of 13 tons. Its total load capacity fits 40-55 m³ bulk materials. The capacity adjusts based on material density. The cargo box uses Q700 high-strength alloy steel. Its side plates are 6mm thick, and the bottom plate is 8mm thick. It has a “U-shaped body + 3D reinforcing ribs” structure. Its anti-deformation ability is 40% higher than conventional designs. This solves cargo box bulging and cracking under heavy loads. The standard inner size of the cargo box is 8.6m×2.55m×1.85m. Its volume reaches 40.5 m³.

2. Lifting System: Fast Speed & Thorough Unloading for Wet/Sticky Materials

It has imported large-bore hydraulic lifting cylinders. Its lifting force is 25% higher than industry peers. No-load lifting time is ≤22 seconds. Heavy-load (rated load) lifting time is ≤38 seconds. The maximum unloading angle hits 68°. Even for wet, sticky slag or clay, it unloads quickly. The residue rate is below 1%.

3. Travel & Safety: All-Terrain Grip & Quick Braking for Bad Weather

It comes with 12.00R22.5 all-steel radial engineering tires. The tread depth is 24mm. Its off-road grip and wear life rise by 35%. The rims use lightweight forged aluminum alloy. They have high strength and reduce unsprung mass. It also has a standard ABS+EBS braking system. Braking response time is ≤0.3 seconds. The rear integrates high-brightness LED outline lights. It also has steering auxiliary lights and red-white reflective signs. This boosts visibility by 60% at night and in bad weather.

4. Auxiliary Configurations: Time-Saving & Fuel-Efficient Practical Add-Ons

It has an innovative “quick-release spare tire bracket”. You can replace the spare tire in 5 minutes. The cargo box tail adds a “flow-guided protective plate”. This cuts driving wind resistance by 10%. It also saves about 8% in comprehensive fuel consumption.

Core Advantages: Why It Stands Out in Engineering Logistics

1. Revolutionary Durability: Longer Fatigue Life & Less Downtime Losses

The high-strength steel cargo box pairs with a reinforced frame. This makes the vehicle’s fatigue life reach 180,000 lifting cycles. It is 35% longer than similar products. This greatly reduces downtime losses from cargo box damage.

2. All-Round Efficiency Improvement: Faster Transport in Muddy Mining Areas

It has fast lifting speed and thorough unloading. It also has all-terrain passability. (3 axles are evenly distributed + wide-base tires.) This improves passability in muddy mining areas by 20%. Thus, material transportation efficiency is 25% higher than traditional equipment.

3. Full-Life Cycle Cost Optimization: Lower Failures & Maintenance Fees

It has a “low failure rate” (hydraulic system leakage drops by 90%). It also has “low maintenance cost” (the wear-resistant cargo box needs no major overhaul for 8 years). Its comprehensive operation and maintenance cost falls by over 40%.
