Global coal mines, thermal power plants and coal trading logistics fleets need high-capacity, dust-proof coal transport semi trailers to realize low-cost long-distance coal transportation. Shandong Junchi develops two mainstream coal transport vehicle types: high-side wall fence semi trailers and large-volume coal dump semi trailers, targeted at raw coal, clean coal and coal powder transportation demands, widely used in coal transport business in Central Asia, Africa and Southeast Asian energy markets.
For bulk raw coal transportation, Junchi’s high-side wall coal fence semi trailers adopt 1.8m-2.6m adjustable high side walls, expanding the internal cargo volume to 85 cubic meters, greatly improving single-trip coal loading volume. The fence frame uses thickened square steel, with detachable fence panels; when transporting large coal blocks, partial fence panels can be removed for convenient forklift loading. The bottom plate of the cargo compartment uses wear-resistant manganese steel, resisting long-term friction of coal blocks without rapid wear and perforation. The factory can additionally install retractable tarpaulin roller devices on the top of the coal transport semi trailers; drivers can automatically unfold the tarpaulin through the hydraulic switch in the cab to cover coal piles, effectively preventing coal dust from flying during highway driving and avoiding coal loss caused by wind and rain.
For coal powder and fine clean coal transport, Junchi’s large-volume coal dump semi trailers are more suitable. The tank-type sealed cargo box can avoid coal dust leakage, and the front hydraulic tipping system realizes fast automatic unloading at power plant storage yards without manual coal shoveling. The hydraulic cylinder adopts high-pressure wear-resistant sealing rings, adapting to frequent daily unloading operations of coal fleets without oil leakage failure.
The chassis design fully considers the heavy-load characteristics of coal transport. All coal transport semi trailers are equipped with reinforced heavy-duty axles and thickened multi-leaf springs, which can withstand long-term full-load coal transportation on gravel mining roads without suspension breakage. Clients can customize the side wall height, cargo compartment length, tarpaulin type, tire specifications and rear unloading door structure according to local coal transportation volume and road weight limit standards.
Shandong Junchi’s quality inspection team carries out full-load vibration tests and tarpaulin waterproof tests for all coal transport semi trailers before shipment, and provides complete export certification documents for energy enterprise customers. A thermal power plant logistics fleet in Kazakhstan purchased 60 units of Junchi high-side wall coal transport semi trailers, and the fleet operation data shows that the single-trip coal transport volume increased by 70%, while coal loss caused by wind dust was reduced by more than 90%, significantly cutting the comprehensive coal transportation cost of the power plant. Focused on high-volume and dust-proof transport demands, Shandong Junchi coal transport semi trailers bring efficient and low-loss haulage solutions to global coal and energy transport fleets.
