Cat 432D Backhoe Loader
The
Caterpillar 432D backhoe loader was manufactured from 2001 to 2006. The Cat 432D
is powered by Caterpillar 3054 DIT 4-cycle 4-cylinder direct injection
turbocharged diesel engine. A 268 cu.in (4.4L) engine has a cylinder bore of
4.13" (105 mm), piston stroke of 5" (127 mm), rated power of 89 hp (66 kW), and
maximum torque of 386 Nm (285 lb-ft) at 1400 rpm.
The Cat 432D is fitted with two types of transmission. Type 1: 4x4 Power
Shuttle transmission with single-stage torque converter. Type 2: 5x3
Auto Shift transmission with single-stage torque converter. The maximum
forward speed - 19.7 mph (31.8 km/h), a maximum reverse speed - 19.7 mph
(31.8 km/h). The closed center load sensing hydraulic system used a
piston pump with a rated capacity of 43 gallons per minute (163 liters
per minute). The main relief pressure is 228 bar (3300 psi). The
Caterpillar 432D is equipped with a hydrostatic steering system,
multiple disc brakes, 12.5/80-18 front tires, and 16.9x28 rear tires.
The wheel base is 83" (2100 mm).
The loader has a maximum lift height of 10 ft 11 in (3321 mm) at pin and
bucket dump clearance of 8 ft 7 in (2613 mm). The lift capacity is 7470
lbs (3388 kg) at maximum height (pivot pin), and breakout force is 11290
lbs (5132 kg). The 89" (2260 mm) standard material bucket has a nominal
heaped capacity of 29.1 cu.ft (0.83 m3).
The backhoe with extendable stick can dig to max depth of 19 ft 4 in
(5894 mm). The digging force is 6070 lbs (2760 kg) for the crowd
cylinder, and 14580 lbs (6627 kg) for the bucket cylinder. The reach
from swing pivot at ground line is 21 ft 10 in (6664 mm). The backhoe
can be equipped with 12" (305 mm), 18" (455 mm), 24" (605 mm), 30" (760
mm), and 36" (910 mm) buckets.
