Rapid Intervention Vehicles

As a hypothetical straight-line width check, a 2,200 mm opening minus the 1,780 mm Tuyi body width leaves 420 mm in total; the 1,940 mm JMC body leaves 260 mm. Those are arithmetic differences, not safe passage clearances. Obtain the width with mirrors and equipment, the gate approach and a swept-path check before selecting either vehicle. A 2.00 m opening would reduce those differences to 220 mm and 60 mm.

In a planning-only example at an assumed constant 200 L/min discharge, 850 L divided by 200 gives 4.25 minutes and 2,000 L gives 10 minutes before deductions for unusable volume or reserve. At 400 L/min the arithmetic halves to 2.125 and 5 minutes. These are nominal-volume calculations, not tested pump performance or operational endurance; establish the actual pump duty and operating fill separately.

For tool-led first response, compare the actual tool inventory, crew seating, power demand, locker dimensions and completed mass before enlarging the tank. Water mass, people and installed equipment must fit the completed axle limits. Keep a separate requirement for replenishment or support from the main appliance; do not assume a larger tank makes a compact vehicle suitable for every rescue task.

Provide the narrowest opening, route and turning restrictions, vehicle height limit, crew and tool list, requested usable water volume, required flow at pressure, refill arrangement and destination. Ask for the completed drawing with mirrors, loaded mass and axle statement, equipment stowage plan and a matching acceptance schedule. Quote the two named configurations against those same entries.
