Grove RT65S

The Grove RT65S is a highly capable rough terrain crane, boasting a lifting capacity of 35 US tons (31.75 metric tons) and designed to tackle demanding construction and industrial tasks. The crane’s four-section trapezoidal boom extends from 33 ft to 112 ft (10.06 m to 34.14 m) and is supported by robust hydraulics. An optional lattice extension further enhances the crane’s versatility by providing additional reach, making it suitable for various complex lifting applications.

Boom and Lifting:

• Boom Length: 33 ft to 112 ft (10.06 m to 34.14 m) with an optional lattice extension that can extend the tip height by an additional 32 ft (9.75 m).
• Boom Nose: Features three heavy-duty sheaves mounted on tapered roller bearings, facilitating smooth reaving and reliable operation during heavy lifts. Additionally, the boom is equipped with integral check valves for safe operation.
• Boom Elevation: Dual double-acting hydraulic cylinders offer boom elevation from -4° to 76°, with combination controls for hand or foot operation, providing flexibility during operation.

Hoist and Winch:

The RT65S is equipped with Grove’s innovative two-speed hoist system, which allows the operator to switch between high line-pull and high-speed hoisting without changing gears. The main hoist features a drum diameter of 16 inches (406 mm) with a high-speed range of 525 FPM (160 m/min) and a line pull of 16,800 lbs (7,620 kg). For more detailed lifting tasks, the auxiliary hoist provides a maximum line pull of 9,145 lbs (4,148 kg).

Engine and Transmission:

The RT65S is powered by reliable engine options such as the Cummins V378-145, a 6-cylinder engine providing 121 hp @ 2800 RPM and 250 ft-lbs of torque at 1800 RPM. The crane utilizes a 6-speed powershift transmission with rear axle disconnect, providing smooth mobility across various terrains.

Hydraulic System:

The crane’s hydraulic system features three main gear pumps with a combined capacity of 112.5 GPM (425 LPM), which powers the boom, outriggers, steering, and swing systems. The system operates at a maximum pressure of 2,500 PSI (175 bar), ensuring powerful and reliable hydraulic performance across all crane functions.

Operator’s Cab:

The full-vision cab is designed for optimal visibility and comfort. It is equipped with tinted safety glass, adjustable seating, and advanced controls for boom and hoist operations. The cab is also fitted with the Kruger Load Moment Indicator system and anti-two-block functionality, providing operators with real-time data on load weight, boom angle, and lift capacity, ensuring safe and efficient operation.

Outriggers and Stability:

The crane is supported by hydraulic double-box beam outriggers with vertical jacks, providing a wide spread of 21 ft (6.40 m) for stability. The hydraulic jacks include integral check valves for safety, while aluminum floats provide a strong foundation on uneven ground.

Steering and Mobility:

The RT65S offers excellent mobility, featuring hydrostatic steering with four steering modes: front-wheel, rear-wheel, four-wheel coordinated, and crab steering. This allows the crane to maneuver easily in tight job sites, further enhanced by the rear axle’s oscillation lockout system for stability during lifts.
