KM-H3 Heavy-Duty Vehicle Washing System, designed for ore trucks, coal haulers, and gravel trucks. Industrial-grade construction ensures durability, powerful cleaning removes stubborn stains, and wear-resistant design withstands harsh environments.

1. Product Overview

Introducing the all-new, upgraded Kaimelon KM-H3 Heavy-Duty Fully Automatic High-Pressure Cleaning System, custom-engineered for 100-ton-class specialized vehicles such as mining dump trucks, coal transport heavy-duty trucks, aggregate haulers, and port freight vehicles. The system features a through-passage design: drivers enter the cleaning zone at low speed, where photoelectric sensors automatically trigger the full spray cycle. As soon as the vehicle exits, the system shuts down instantly—requiring zero manual intervention throughout the process. The KM-H3 utilizes a layered, 3D high-pressure spray architecture with three dedicated modules: side-body high-pressure rinsing, full undercarriage high-pressure jetting, and specialized tire/wheel high-pressure spraying. It delivers enhanced pressure to thoroughly clean mud-prone areas below 1.2 meters from the ground, effectively stripping away heavy mineral residue, coal dust, sand, and silt. Heavy-duty vehicles in mining and coal sites typically carry 50–100 tons and often require washing while fully loaded. Many are equipped with dust covers and feature complex shapes, protruding parts, and numerous external accessories. Conventional brush-based wash systems risk damaging tarps, side mirrors, and paintwork, creating dual hazards of equipment damage and vehicle scratches. To address these challenging conditions, the KM-H3 employs a pure high-pressure, contactless cleaning solution that eliminates all risks associated with brush contact. It adapts seamlessly to irregular shapes, protruding components, and various vehicle dimensions. Equipped with three main high-pressure water jet racks plus multiple side sprays and undercarriage boost circuits, the KM-H3 generates powerful water impact to rapidly remove large areas of accumulated dirt. Its reinforced load-bearing frame can stably support fully loaded 100-ton vehicles during cleaning. Designed for continuous, uninterrupted operation, the system offers stable automation, minimal downtime, compact footprint, and easy installation. Widely deployed in open-pit mines, thermal power plants, aggregate yards, coal facilities, and freight terminals, the KM-H3 is the standardized, compliance-ready solution for industrial dust suppression and fleet sanitation.

II. Core Functional Advantages of the Complete Machine

• High-power, ultra-high-pressure pump station paired with multiple 3D high-pressure water jet nozzles for powerful penetration and thorough removal of mud and coal ash from vehicle bodies.

• Infrared photoelectric sensors enable automatic water supply start/stop. Sprinklers activate when vehicles enter and shut off immediately upon departure, ensuring fully intelligent, unattended operation.

• Brushless contact cleaning design that won't scratch your factory paint, eliminating scratches on side mirrors, canvas roofs, and vehicle edges.

• Independent chassis and dual-side tire pressure washing assembly for deep cleaning of wheel rim gaps and heavy mud accumulation on the undercarriage.

• Drive-through tunnel with wash-on-demand mode, high-efficiency assembly-line operation, and impressive daily vehicle throughput.

• Cost-effective cleaning equipment for heavy-duty industrial and mining scenarios. Moderate upfront investment, low long-term maintenance and parts replacement costs, delivering superior total cost of ownership.

• Industrial-grade core electrical and hydraulic components ensure stable, reliable operation in harsh, high-dust mining environments.

• Optional high-volume, high-power air-drying unit available to quickly remove water residue after washing and reduce manual wiping.

• Optional sewage sedimentation and circulation treatment system available; filters and recycles wash water to significantly reduce tap water consumption on-site.

• Integrated water-saving layout with per-vehicle consumption control, meeting environmental protection, water conservation, and dust suppression standards for industrial and mining sites.
