Cat 424D Backhoe Loader
The
Caterpillar 424D backhoe loader was manufactured from 2001 to 2006. The
components of Cat 424D driveline system: a 258 cu.in (4.2L) Caterpillar 3054B
4-stroke 4-cylinder direct Injection liquid cooled diesel engine, and 4x4 Power
Shuttle full synchromesh transmission with single-stage torque converter.
The engine has a cylinder bore of 4.06" (103 mm), piston stroke of 5.0"
(127 mm), and rated power of 74 hp (55 kW). The max travel speed
(forward/reverse): 19.7 mph (31.8 km/h). The closed center load sensing
hydraulic system used an axial piston pump with a flow of 37 gpm (139
lpm). The main relief pressure is 207 bar (3000 psi). The Cat 424D
backhoe loader was equipped with 12.5/80-18 (2WD) or 340/80R18 (4WD)
front tyres and 16.9x28 (2WD) or 16.9R28 (4WD) rear tyres. The wheelbase
is 83" (2100 mm).
The loader has a lift capacity (at pin) of 5320 lbs (2416 kg) to max
height of 10 ft 10 in (3321 mm), and boom breakout force of 8750 lbs
(3977 kg). The clearance with bucket dumped is 8 ft 8 in (2633 mm) at
maximum dump angle of 43 degrees. 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 has a max digging depth of 19 ft 4 in
(5894 mm). The dipperstick digging force is 5670 lbs (2577 kg), and
bucket digging force is 11610 lbs (5277 kg). The overall reach from
swing pivot at ground level is 21 ft 10 in (6664 mm). The backhoe can be
fitted with 12" (305 mm), 18" (455 mm), 24" (605 mm), 30" (760 mm), and
36" (910 mm) buckets.
