Cat 438C Backhoe Loader
The
Caterpillar 438C is a 4x4 backhoe loader with all wheel steer system. This model
was manufactured between 1986 and 2000. The Cat 438C is equipped with a
Caterpillar 3054 DIT 4-cylinder direct injection liquid-cooled turbo diesel
engine rated at 85 Hp (63 kW). The max. torque is 435 Nm (305 lb-ft) at 1400
rpm.
The powershuttle transmission includes a 4x4 full synchromesh gearbox
and single-stage torque converter. The maximum forward or reverse speed
- 20 mph (32.3 km/h). The closed center load-sensing hydraulic system
includes a piston pump with flow rate of 43 gpm (162 lpm).
The hydraulic pressure is 207 bar (3000 psi). The Cat 438C backhoe
loader is equipped with 12.5/80-18 front tyres and 16.9-28 rear tyres.
The front end loader has a lifting capacity (bucket pin) of 7275 lbs
(3300 kg) to full height of 133" (3360 mm), and boom breakout force of
11105 lbs (5048 kg). The bucket dump clearance is 102.8" (2600 mm) at
max dump angle of 45 degrees. The 89" bucket has a rated capacity of
33.3 cu.ft (0.95 m3).
The backhoe with standard dipperstick digs to a maximum depth of 14 ft 2
in (4326 mm). The digging force is 12195 lbs (5545 kg) for the bucket
cylinder and 7427 lbs (3376 kg) for the crowd cylinder. The overall
reach from swing pivot (extendable dipperstick) is 22 ft 2 in (6756 mm)
at ground level. The backhoe can be fitted with 12", 16", 18", 24", 30",
36" standard material buckets.
