This 1997 Grove RT9100 is a rough terrain crane — sometimes referred to as an RT crane — designed to lift and place heavy loads across uneven, soft, or unprepared ground where conventional cranes cannot easily operate. Grove is a well-established name in the lifting industry, with decades of experience manufacturing mobile cranes and aerial work platforms for construction, infrastructure, oil and gas, and industrial projects worldwide.
The crane is rated for a maximum load capacity of 90,718.5 kg, making it a substantial machine suited to demanding heavy-lift applications. Its four-section boom reaches a maximum height of 34.7 m at full elevation without additional configuration, and the maximum angle of elevation is 80 degrees. At maximum climb angle the minimum height is 11 m. The useful working radius runs from a minimum of 3 m out to a maximum of 30.5 m, giving operators a broad range of pick-and-carry positions, while the superstructure rotates at a swing speed of 2 RPM.
Power comes from a Cummins 6CTA engine, an 8.3-litre turbocharged inline-six diesel displacing 8.3 litres. It produces 186 kW measured at 2,200 RPM and delivers a maximum torque of 1,076.5 Nm at 1,500 RPM. The electrical system operates at 12 V, and the fuel tank holds 378.5 litres. The hydraulic system carries a fluid volume of 1,419 litres.
The carrier is driven through a force-shift transmission with six forward and six reverse gears, reaching a maximum forward travel speed of 26 km/h. The crane rides on 33.25×35-32PR tyres and has an operating weight of 60,989.1 kg. This used example is located in Chile.
