Dump Trailer
The CNFORCE Heavy-Duty Dump Semi Trailer is engineered for high-volume bulk material transport across mining, quarry, and infrastructure construction sites[1][2]. Built with high-tensile T700L steel main beams and wear-resistant NM450 cargo bodies, this tipper trailer handles aggressive materials such as sand, gravel, crushed stone, and mining ores[3][4]. Equipped with heavy-duty FUWA axles and a reliable HYVA hydraulic lifting system, it delivers rapid tipping cycles, structural stability, and high payload efficiency[3].

Key Features and Applications
Wear-Resistant Cargo Body Construction
The dump body is fabricated from high-strength NM450 wear-resistant steel, utilizing a 6 mm bottom plate and 3 mm side walls[3]. This design provides high impact and abrasion resistance, preventing floor deformation and premature wear when hauling sharp blasted rock, mineral ores, and coarse gravel[3][4].
High-Tensile Steel Chassis Structure
The main chassis beams are fabricated from T700L high-strength steel using automated submerged arc welding, reinforced by 18 mm channel steel side beams[3]. This rigid framework resists twisting, cracking, and bending moments under heavy payloads when navigating uneven haul roads and unpaved quarry terrains[3][5].
Reliable HYVA Hydraulic Tipping System
The tipping mechanism incorporates a heavy-duty, multi-stage telescopic hydraulic cylinder from HYVA[3]. The front-end lifting geometry provides stable lifting power, smooth hydraulic oil return, and reliable tipping balance during full-capacity discharge cycles[3].
Multi-Axle Suspension Configuration
Equipped with four 13-ton FUWA axles, the chassis integrates an air suspension with an axle-lifting system on the first axle and heavy-duty mechanical leaf spring suspensions on the rear three axles[3]. This setup balances axle load distribution when loaded and reduces tire friction and fuel consumption when running empty[3].
Primary Industry Applications
-
Mining & Quarrying: Transporting coal, iron ore, copper ore, and blasted quarry rock[4][6].
-
Infrastructure Construction: Bulk transit of sand, gravel, subgrade soil, and crushed stone[4][7].
-
Civil Earthworks: Site leveling, excavation backfill, and building waste removal[7].

Dimensions and Operating Range
The dump semi trailer features external dimensions of 11,000 mm in length, 2,500 mm in width, and 3,850 mm in height[3]. The internal cargo bed measures 10,000 mm × 2,350 mm × 1,700 mm, delivering an effective loading volume of 40 cubic meters[3]. The front-lift hydraulic configuration allows a steep dumping angle to ensure clean, residue-free discharge of sticky clay, sand, and aggregate materials[3][4].
Supplier Support
We provide technical documentation, configuration consulting, and export procurement support for CNFORCE dump semi trailers[1][8]. Our engineering team assists with fifth-wheel height matching and kingpin compatibility for seamless pairing with your prime movers[9]. For international transport, trailers are shipped via RORO or bulk cargo vessels, with comprehensive surface treatment including sandblasting, protective paint coating, and maritime wax spraying to prevent saltwater corrosion[2][10]. Replacement components and maintenance parts are supported through our export supply chain[1].
Frequently Asked Questions
What is the payload capacity and body volume of this dump trailer?
The trailer is rated for a 70-ton payload with an internal cargo volume of 40 cubic meters, making it suitable for high-density mining and construction bulk transport[3].
What hydraulic lifting cylinder is used on this trailer?
This model is equipped with a complete front-mounted HYVA hydraulic telescopic cylinder system, providing stable lifting power and controlled tipping speeds[3].
What materials are used to construct the chassis and cargo box?
The cargo box is constructed from NM450 wear-resistant steel (6 mm floor and 3 mm side walls), while the main chassis beams are built from submerged arc welded T700L high-tensile steel[3].
