Products Description
Wildland fire engine is also named as HOWO 4x4 tanker fire truck, which is a specialized fire engine that can negotiate difficult terrain for wildfire suppression. A wildland fire engine HOWO is smaller than standard fire trucks and has a higher ground clearance based on its 4x4 truck chassis. They may also respond to emergencies in rough terrain where other vehicles cannot respond. Many wildland engines feature four-wheel drive capability to improve hill climbing and rough terrain capability. Some wildland apparatus can pump water while driving (compared to some traditional engines which must be stationary to pump water), allowing "mobile attacks" on vegetation fires to minimize the rate of spread.
Fire departments that serve areas along the wildland–urban interface have to be able to tackle traditional urban fires as well as wildland fires. Departments in these areas often use a wildland-urban interface engine, which combine features of a standard fire engine with that of a wildland fire engine.

Technical Parameters
The HOWO 4x4 tanker fire truck mainly used for water spraying and fire extinguisher. So the water tender is a specialist fire appliance with the primary purpose of transporting large amounts of water to the fire area to make it available for extinguishing operations. These are especially useful in rural areas where fire hydrants are not readily available and natural water resources are insufficient or difficult to exploit. Most tankers have an on-board pumping system. This pump is often not of sufficient power to fight fires (as it is designed to be attached to a fire engine), but is more often used to draw water into the tender from hydrants or other water sources. Many tankers are equipped with fast-drain valves on the sides and back of the truck. This allows firefighters to empty thousands of gallons of water into a portable water tank in just a few seconds.
Most Sinotruk HOWO fire rescue water tenders are designed to carry loads of 5,000–12,000 litres (1,100–2,600 imp gal).
