ASV RS-60 Troubleshooting
The
ASV RS-60 skid steer loader driveline system components: a 135 cu.in (2.2L)
Perkins 404D-22T four-cylinder turbocharged diesel engine with a rated power of
60 hp (44.7 kW) and 2-speed hydrostatic transmission. The hydraulic system has a
pump with a rated capacity of 17.1 gal/min (65 l/min). The system relief
pressure is 3335 psi (230 bar). The ASV RS60 is equipped with a radial-lift
loader boom, 80 ANSI continuous roller chains, and 10x16.5 tires. The skid steer
loader has a boom lifting force of 4750 lbs (2155 kg) and bucket breakout force
of 4750 lbs (2155 kg). The rated operating capacity is 2000 lbs (907 kg), and
tipping load is 4000 lbs (1814 kg).
