The
Cat 232D skid steer loader driveline system components: Caterpillar C2.2T
four-cylinder direct injection turbocharged diesel engine with a rated power of
65.8 hp (49.1 kW), and 1-speed or 2-speed hydrostatic transmission. The
hydraulic system has a pump with a rated capacity of 18 gal/min (69 l/min) or 26
gal/min (99 l/min). The Caterpillar 232D is equipped with a vertical-lift loader
boom, 80HS drive chains, and 10.00x16.5 standard tires. The skid steer loader
has a maximum lift height of 118.1" (3000 mm) to hinge pin and dump height of
88.7" (2255 mm). The rated operating capacity is 1850 lbs (840 kg), and tipping
load is 3700 lbs (1680 kg).
