Cat 426C Backhoe Loader
The
Caterpillar 426C backhoe loader was manufactured from 1996 to 2000. The
components of Cat 426C powertrain system: Caterpillar 3054 DIT four-stroke
4-cylinder direct injection turbocharged diesel engine, and 4x4 power shuttle
transmission with a single-stage torque converter.
A 4L (243 cubic inches) engine power rating is 80 hp (60 kw) at 2200
rpm. The max travel speed (forward/reverse): 21.1 mph (34 km/h). The
closed center load-sensing hydraulic system includes an axial piston
pump with fluid flow rate of 43 gal/min (162 l/min). The main relief
pressure is 3000 psi (207 bar).
The Cat 426C is equipped with 11L-16 front tyres and 16.9-24 rear tyres
(2WD models), or 12.5/80-18 front tyres and 19.5L-24 rear tyres (4WD
models). The loader has a maximum lift height of 10 ft 9 in (3290 mm) at
pin, and clearance with bucket dumped of 100 in (2530 mm). The lift
capacity is rated at 7034 lbs (3190 kg) to max height, and bucket's
breakout force is 10541 lbs (4790 kg). The loader bucket has a width of
95 in (2400 mm) and nominal heaped capacity of 29.2 cu.ft (0.84 m3).
The backhoe work ranges consist of a bucket digging force of 14440 lbs
(6560 kg), standard dipperstick digging force of 8510 lbs (3870 kg), and
extendable dipperstick digging force of 6310 lbs (2870 kg). The maximum
digging depth (standard stick or extendable stick) is 15 ft 6 in (4721
mm) or 20 ft 3 in (6169 mm), and reach from swing pivot at ground level
(standard stick or extendable stick) is 19 ft 10 in (6056 mm) or 24 ft 3
in (7395 mm). The backhoe is equipped with 16", 20", 24, 30" and 36"
standard material buckets, 12", 16", 18", 24, 30", 36" heavy duty
material buckets, and 18", 24" extreme service buckets.
