Tadano GR-350N-1

The Tadano GR-350N-1 rough terrain crane is designed for compact, high-performance lifting in space-constrained environments. It features a hydraulically telescoping 5-section boom ranging from 9.5 to 36.3 meters, constructed with hexagonal box geometry for enhanced strength. The boom is supported by a two-stage offset jib system measuring 8.0 and 13.0 meters, offering total lifting heights up to 50.1 meters. This allows for flexibility across various lifting radii and boom angles.

The main boom hoists up to 35,000 kg at a 3.0-meter radius (on 9.5 m boom with 10-part line), while maintaining solid performance across extended lengths: 7,000 kg at 8.0 meters on full boom extension. The jib enables additional lifting at high angles, with capacities like 3,400 kg at 78° (8.0 m jib) and 2,200 kg at 77° (13.0 m jib).

Hoisting is powered by main and auxiliary winches with high line speeds of 127 m/min (single line, 4th layer). Slewing is smooth and continuous at 2.5 rpm, driven by a planetary gear reducer and negative brake system. Boom elevation reaches 83.5° in just 54 seconds, supported by a pressure-compensated double-acting cylinder for precision and safety.

The GR-350N-1 is powered by a Mitsubishi 6M60-TLE2A turbocharged engine rated at 200 kW (272 PS) at 2,700 rpm, with maximum torque of 785 Nm at 1,400 rpm. The transmission includes a 4-speed power shift system with Hi/Lo settings, and drive options for 4×2 or 4×4 configurations. The crane’s top speed is 49 km/h with a minimum turning radius of 5.2 meters in 4-wheel steer mode.

Its hydraulic system consists of two piston pumps and three gear pumps with a 418-liter tank. Full hydraulic X-type outriggers extend to a maximum width of 6.7 meters, with intermediate stages at 6.3, 5.2, 3.8, and a minimum of 3.3 meters—each with independent control.

Safety systems include Tadano’s AML (Automatic Moment Limiter), swing range limiter, boom elevation lock, overwind protection, and hydraulic locks on all major functions. Operator convenience is elevated with an air-conditioned cab, ergonomic seat, foot controls, rear monitor, and dehumidifier.

Overall, the GR-350N-1 offers an ideal mix of lifting power, mobility, and compact design, making it well-suited for urban construction, plant maintenance, and infrastructure development where 35-ton class performance is required.
