Suction and Cleaning (Environmental Maintenance Equipment) Related Products

We are a fully custom-made special vehicle manufacturer that solves problems on-site, from urban infrastructure maintenance to disaster recovery. Holding approximately 80% of the domestic market share for powerful vacuum vehicles and high-pressure cleaner trucks, we handcraft each vehicle that supports daily life.

What are "Powerful Vacuum Vehicles" and "High-Pressure Cleaner Trucks"?

Powerful Vacuum Vehicle

This vehicle generates powerful suction using airflow to vacuum up mud, stones, gravel, and more. Beyond cleaning sewers and side ditches, it supports daily infrastructure behind the scenes, such as recovering sediment during disasters.

High-Pressure Cleaner Truck

This vehicle utilizes water pressure to scrape off and wash away stubborn dirt and blockages. It keeps sewers and street side ditches clean, preventing urban flooding before it happens.

The high-pressure cleaner truck washes away mud with the power of water, and the powerful vacuum vehicle collects the accumulated mud all at once.

What is a "Microwave Extraction Device"?

Microwave Extraction Device

This device utilizes microwave (electromagnetic wave) energy, same as microwave ovens, to extract active ingredients (essential oils, floral waters) from various plants quickly and efficiently.
Born from customer feedback wishing to "make effective use of yuzu juice pomace," the extracted active ingredients are used as flavorings and fragrances in foods, cosmetics, and other products. Furthermore, the residue after extraction is repurposed as compost or livestock feed.

How a Powerful Vacuum Vehicle is Made

Kanematsu Engineering's products are "custom-made" tailored to each customer's site.
Here is the journey from the initial consultation to the completed vehicle's departure across the nation.

Needs Assessment & Proposal

We listen to your on-site challenges and propose the optimal specifications.

Our sales representative will carefully listen to your on-site concerns and intended application. Based on this information, we will evaluate the necessary features, tank size, and other requirements to propose the optimal specifications tailored to your needs.

Design & Procurement

Drawing blueprints to shape requests and gathering necessary parts

Based on information from sales, the design team creates drawings tailored to the customer's application. We procure numerous parts according to custom specifications that vary with each vehicle, moving forward with preparations for manufacturing.

Manufacturing

Preparing the truck chassis base and manually creating airflow pathways

We modify the base "chassis (truck without a bed)" by cutting frames and performing other work to equip the body. Simultaneously, we manually weld and assemble each pipe to create the airflow that vacuums up materials.

Painting

Manually painting everything from small components to large tanks

After performing a surface treatment called "shot blasting" to improve paint adhesion, all parts, big and small, are painted manually. We also accommodate customer requests for specific color schemes and designs.

Assembly & Outfitting

Assembling parts and mounting the tank

Painted pumps, piping, and other components are assembled onto the chassis. Then, the largest component, the tank, is lifted by a crane, mounted onto the chassis, and secured.

Inspection

Meticulously checking for anomalies using human eyes and ears

We measure the weight, length, width, and height of the completed vehicle. Additionally, we meticulously inspect the undercarriage for abnormal sounds, heat generation, loose bolts, and other issues.

Shipping

Finishing up and sending out vehicles to customers nationwide

We perform finishing touches such as neatly bundling wiring and affixing caution stickers. After completing final inspections, vehicles are shipped from our Kochi factory to customers nationwide.

After-Sales Service

Our relationship with a product doesn't end with delivery. Because these vehicles support infrastructure in harsh working environments, we have established a support system to ensure long and safe operation. We respond promptly to any potential issues, continuing to support our customers' operations and peace of mind.

Case Studies

In the event of natural disasters such as earthquakes or torrential rains, as well as unforeseen accidents, our powerful vacuum vehicles and high-pressure cleaner trucks are utilized for infrastructure restoration and environmental conservation. Here, we introduce our operational track record at various sites aimed at "protecting safe living."
