Water Tank Assembly
Overall imported 304 stainless steel plate construction with internal welding stiffeners.
Heat preservation design with 30mm thick foam insulation for operation in cold climates.
The tank features a circular arc bottom with a specific gradient for efficient drainage.
Equipped with anti-swing boards to maintain vehicle stability during transport.
Passivation treatment ensures long-term corrosion resistance.
Exterior finished with imported automobile special paint and anti-slip top surface.
Food-grade high-transparent level gauge for accurate liquid monitoring.
Equipped with a round cover manhole for easy cleaning, disinfection, and inspection.
Sewage & Tank Integration
The system comprises a flushing water tank, vacuum pump circulating water tank, and a sewage buffer unit. While integrated as one unit, each compartment is completely isolated.
Sewage tank includes an upper outlet designed for easy dredging.
The bottom features a stainless steel ball valve controlled by a hydraulic cylinder for hygienic operation.
Electric devices are utilized for the discharging valves.
Rear-mounted liquid level observation window for easy monitoring.
Water Supply System
Stainless steel corrosion-resistant centrifugal pump (Max flow: 20m³/h, Pressure: 0.25-0.35 Mpa).
Water lines utilize stainless steel tubes and food-grade hoses.
Standard aircraft water supply joints at the front end.
Automatic rewinding hose reel for convenient storage and operation.
Pump room is fully insulated and heated for cold-weather reliability.
Sewerage System
Equipped with standard aircraft sewage joints and high-quality pipes.
The pumping system features a water ring vacuum pump and stainless steel suction pipes.
Gravity-assisted discharge via electric control of the hydraulic ball valves.
Tail Working Platform
Elevating platform with a height range of 400mm to 2800mm.
Maximum platform load capacity: 160 kg.
Safety features: 1.1m stainless steel guardrails, task lighting, and anti-skid hollow steel flooring.
Equipped with touch switch controls.
Hydraulic & Electrical Systems
Hydraulic system uses imported brand valves, gear pumps, and electromagnetic valves.
Seamless galvanized steel hydraulic pipes with card-type joints to minimize leakage.
24V DC electrical system with centralized control box in the rear frame.
Safety: Emergency stop switches, yellow stroboscopic LED warning lights, and waterproof sealed plugs.
Integrated night work lighting at the front of the tank.
Vehicle Accessories
Complete with spare tire and non-slip rubber wheel blocks.
Two 8kg fire extinguishers with dedicated storage brackets.
Comprehensive maintenance tool kit and essential spare parts for engine and hydraulic systems.
Frequently Asked Questions (FAQ)
What material is the tank made of?
The entire tank is constructed from high-quality imported 304 stainless steel, which undergoes passivation treatment to prevent corrosion over long-term use.
Is this vehicle suitable for extremely cold climates?
Yes. The water tank features 30mm thick foam insulation, and the pump room and pipelines are equipped with heating devices and warm air systems derived from the engine cooling system.
What are the specifications of the water supply pump?
The unit uses a stainless steel corrosion-resistant centrifugal pump with a maximum flow rate of 20m³/h and an operating pressure range between 0.25 and 0.35 Mpa.
What is the lift capacity and range of the working platform?
The tail elevating platform can reach heights from 400mm to 2800mm and is designed to support a load of up to 160kg.
How is the sewage discharge system operated?
The discharge system is controlled electrically. Operators can use the control cylinder to open the stainless steel ball valve, allowing sewage to discharge via gravity efficiently and hygienically.
What safety features are included for night operations?
The vehicle is equipped with yellow stroboscopic LED warning lights on the roof, dedicated task lighting on the working platform, and specific lights installed at the front of the tank for night-time visibility.
