Remote control hydraulic fan or fog stream nozzles allow adjustable stream patterns for use with Mega water cannons.
The anti-siphon fill pipe is used with any pressurized water source. It is specifically designed to accommodate municipal water systems and fire hydrants requiring an air gap to prevent water siphoning back into the supply.
An extension cable to relocate your camera from the truck to the water tank.
The conical fill port allows for easier positioning of the water fill source over the main fill port of the tank.
The Corrosion Resistant package protects against tank and component corrosion caused by the harsh waters often found in mining, construction, and landfill environments. Protecting your tank against corrosion adds longevity and dependability to your tank and spray system. The package includes:
Mega DiSCS®provides precise application of water spray using CAN bus and logic control technology to operate the spray control system. DiSCS® provides control of all water distribution systems. GPS sensing within DiSCS® automatically regulates the amount of water spray applied relative to vehicle ground speed or distance traveled. This system also provides water pump system protection against operator-induced sudden starts and stops, low water level and overheating due to extended water pump operation.
The quick dump drain valve option is a large drain located at the bottom rear of the tank. This option is available with manual or hydraulic remote actuation.
Mega offers two hydraulically-actuated dump bars. Mega's pressurized dump bar sprays penetrating jets of water directly onto the ground. The gravity dump bar is fed directly from the bottom of the water tank and may be used with the water pump turned off to reduce water flow and pressure.
Mega offers complete factory installation for articulated truck tanks for both customer-supplied and Mega-provided tractors. Factory installation includes complete testing prior to delivery.
Multiple fall protection, D-ring style tie-off points are welded to the top of tank.
The Mega foam agent tank is mounted externally on the top of the water tank. The foam agent tank size varies by model. Mega’s foam agent fire suppression system can be ordered as an option on a new Mega water tank or as a retro kit for installation on an existing water tank.
The front bumper spray is commonly used to “sweep” a surface with high pressure fans of water. Spray heads are mounted to spray from both sides of the tractor. The spray heads are fully adjustable for vertical and horizontal directions. The location of the spray bar allows the cab hood to fully tilt and open for engine service. Front bumper spray may restrict cab access. Note: This item is available by special request.
Hose reels installed on Mega tanks include a high quality water hose and an adjustable fog to stream nozzle. Hose reels come in various sizes and are available with manual, spring, or hydraulic rewind. Sizes vary by model.
Mega tanks are abrasive blasted prior to the application of the interior coating. The epoxy lining is well suited for harsh, acidic, alkaline, and salty waters. Urethane lining is very effective in normal to salty waters. Coating data sheet and MSDS available upon request.
Magnesium anodes are placed in each tank compartment to reduce corrosion of the tank interior.
The Mega Product Support team offers on-site technical assistance, service advice and training to facilitate installation and reduce field assembly and component repair time.
Quick change component packages provide specific operation-critical parts for the Mega water tank spray system. Stocking critical parts reduces downtime by eliminating delays related to acquiring replacement parts. QCCP kits are designed specifically for each tank configuration.
The Mega stainless steel hydraulic spray head valve is engineered for use in the most severe environments. The stainless steel hydraulic spray head valve is interchangeable with the Mega aluminum hydraulic spray head valve. Mega hydraulic spray head valve are actuated by a stainless steel, double-acting hydraulic cylinder.
Suction loading provides tanks with self-loading ability via the discharge pump priming reservoir or a separate, self-priming water pump. Suction loading is used to fill the tank from a natural or man-made reservoir. Discharge pump configurations include an auxiliary manual priming pump, and require customer-provided suction hose. Self-priming pump configurations include storage tubes and hose.
Optional swivel couplings allow for vertical spray direction adjustment. Each spray head rotates horizontally to adjust water spray fan direction.
Two spray head valves are mounted on the front quadrant of the tank for spraying vertical fans of water.
Mega water cannons are designed and built to perform in the most severe environments of mining and construction. Our water cannons are ideal for fire suppression, high pressure equipment washing, and applications requiring long-distance or adjustable spray patterns.
