Case 480B Backhoe Loader
The
Case 480B Construction King backhoe loader was manufactured between 1971 and
1977. The Case 480B CK is powered by 188 cu.in (3.1 L) G188D 4-cylinder
liquid-cooled diesel engine with a maximum power of 41.5 hp (30.9 kW), or 148
cu.in (2.4 L) G148B 4-cylinder gasoline engine with a maximum power of 38.5 hp
(28.7 kW).
The Case 480B backhoe loader fitted with 2 transmission options:
mechanical shuttle transmission with 8 forward and 8 reverse gears, or
4x4 synchronised shuttle shift transmission.
The maximum travel speed (forward/reverse): 16.9 mph (27.2 km/h) and
21.1 mph (33 km/h). The open center hydraulic system includes a gear
pump with fluid flow rate of 21 gpm (79.5 lpm). The hydraulic pressure
is 145 bar (2100 psi). The Case 480B is equipped with 7.50x16 front
tyres and 17.5Lx24 rear tyres. The wheelbase is 77.2 in (1960 mm) for
gasoline models and 78.4 in (1990 mm) for diesel models.
The loader has a lifting capacity of 2600 lbs (at pivot pin) to full
height of 120.8 in (3060 mm), and boom breakout force of 5500 lbs. A
full dump clearance with a 39-degree maximum dump angle is 105.7 in
(2680 mm). The raising cycle time is 3.5 sec. from ground line to
maximum height, and bucket dump time is 1.8 seconds. The loader is
equipped with 63" and 73" buckets.
The backhoe operational data includes a bucket digging force of 6870 lbs
(standard) or 4600 lbs (extendahoe), and dipperstick dig force of 4650
lbs (standard) or 3300 lbs (extendahoe). The maximum digging depth is
148 in (3750 mm) for standard backhoe or 180 in (4570 mm) for
extendahoe, and reach from swing pivot is 184.7 in (4690 mm) with a
standard stick or 219.2 in (5560 mm) with extendable stick. The backhoe
can be equipped with 12", 16", 18", 24", 30" and 36" buckets.
