Engine 1844 is a 2010 HME 1871 Spectr/Toyne 1500/3000 pumper tanker. The hydraulic rack seen on this side stores the portable tank. Larry Shapiro photo The Spring Grove Fire Protection District in McHenry County recently received an early delivery of their new pumper/tanker from Toyne in Breda, Iowa. This new unit, Engine 1844, features an HME 1871 Spectr cab and tandem axle chassis with a large extension and raised roof to accommodate an enclosed, top-mount pump panel. It’s set to replace two older units—a 1985 Ford C-Series Pierce 1250/1000 engine and a 1980 GMC 7000/US Tanker 2,200-gallon tanker. The top-mounted pump panel is enclosed within the super command cab, similar to Spring Grove's 1999 HME/US Tanker pumper. Larry Shapiro photo Equipped with a 1,500 GPM pump, the new pumper/tanker has a 3,000-gallon water tank and a 40-gallon foam tank. Both sides of the long body include high-side compartments, allowing for easy access to the ladders on the officer’s side and the portable tank on the driver’s side via overhead hydraulic storage racks. The officer's side of the rig also features high-side compartments and hydraulic ladder rack storage for the ground ladders. Larry Shapiro photo One unique feature of Engine 1844 is its extendable chutes on either side, used to discharge water into a portable tank. Unlike most tankers, these chutes are located just behind the pump module, not at the rear of the vehicle. This design allows for more efficient water transfer during operations. The extendable discharge chute to dump the water into a portable tank is located just behind the pump module. There is a similar chute on the opposite side of the unit.

Galvanized steel pipe is a kind of Carbon Steel Pipe, mostly welded pipe, Galvanized steel pipes are divided into cold galvanized steel pipes (electro galvanized steel pipes) and hot-dip galvanized steel pipes. At present, hot-dip galvanized steel pipes are mainly used in fire protection, electric power and highways.
Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for water transmission, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil transmission pipes in the petroleum industry, especially in offshore oil fields, as well as pipes for oil heaters, condensing coolers, coal distillation oil washing exchanges of chemical coking equipment, as well as trestle pipe piles, support frames of mine tunnels, etc.
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc.
Hot-dip galvanizing (HDG) is the process of coating iron, steel or ferrous materials with a layer of zinc. This done by passing the metal through molten zinc at a temperature of 860°F (460°C) to form zinc carbonate (ZNC03). Zinc carbonate is a strong material that protects steel and can prevent corrosion in many circumstances. Hot-dip galvanizing can be carried out cheaply and in large batches.
