The HOWO 4x2 emergency water fire rescue truck is built on a SINOTRUK HOWO 4×2 chassis with a 3800 mm wheelbase. It runs on a YC4E140-33 engine rated at 140 HP with a manual transmission. The truck carries a 4000L water tank and a 2000L foam tank. A CB10/30 pump (30 L/s at 1.0 MPa) and a roof mounted PS30 monitor (30 L/s, water ≥55 m, foam ≥42 m) handle fire suppression. A PH32 foam proportioner (3%-6% mixing ratio, 8-32 L/s flow range) automatically mixes foam concentrate with water. Standard gear includes hoses, suction tubes, couplings, foam gun, and basic tool kit.
