Performance Feature
1. Superior performance and rigorously tested
The YT3621 mining dump truck is scientifically designed and matched with a powerful engine and strong climbing ability, aimed at severe road conditions and large gradients.
2. High safety
The rigid dump truck adopts a dual-circuit braking system and engine secondary braking system to fit severe driving conditions. The skeleton-type reinforced cab ensures the safety of the vehicle and the driver.
3. Solid and durable
Based on mine conditions and engineering concepts, a large-section box-shape welded rigid frame enhances bending and twisting resistance. High-strength steel girders ensure great carrying capacity and long fatigue life, while the mining suspension and engineering axles suit severe mining conditions.
4. Attractive appearance and comfortable cab
The mining dump truck has a well-designed appearance showing both the sturdy power of mining machinery and the coordination of automobiles. The luxury cab interior includes a streamlined instrument panel, assembled instruments and flame-retardant interior materials.

YT3621 in Production: Where It Earns Its Keep
The YT3621 has spent three consecutive years in the China Construction Machinery TOP50, a ranking driven by operating data rather than marketing claims. In open-pit coal, limestone and hydropower projects, the truck's duty is consistent: load at the face, climb a 8–10% ramp, dump, return — 20 to 25 cycles per shift when the fleet is balanced against a 5–7 m³ excavator bucket.
Design Details That Show Up in the Cost Sheet
- Frame and suspension: the rigid frame is stress-relieved after welding, and the suspension layout is tuned for haul-road speeds without cab shock — operators hold cycle speed longer.
- Braking and retarder: service brakes sized for full-load descent, with retarder capacity that keeps downhill control on long ramps.
- Body and dump geometry: the 45°+ dump angle clears wet clay and coal without hang-up, so load-out at the dump point stays on schedule.
- Serviceability: grouped grease points and a tilting cab shorten PM stops; the service network carries the YT3621's filters and wear parts as standard stock.
For haul cycles in the 2–5 km band, the YT3621 is typically specified with a 4:1 truck-to-excavator ratio. Talk to the Yutong mining team with your ramp profile and cycle time and you will get a fleet plan with numbers you can check, not a brochure.
