Product Description

The Tadano GR-700N-1 (G3α), also known as the CREVO 700 G3α, is a 70-ton class rough terrain crane designed for high lifting performance, versatility, and ease of operation. Introduced in mid-2013 as an upgrade from the previous 60-ton class model, it offers increased lifting capacity, a longer boom, and advanced features that improve both productivity and safety on-site. The crane is built with a 6-section fully hydraulic boom that extends from 9.8 meters up to 44.0 meters. At maximum boom length, it can lift up to 8.2 tonnes. For even greater reach, it can be fitted with a 3-section fully automatic jib, extending the crane’s total lifting height to 63.0 meters, which is among the best in its class. The jib itself ranges from 8.4 to 17.7 meters and utilizes Tadano’s SACO Jib system, allowing for easier, safer installation without the need for work-at-height procedures.

The GR-700N-1 (G3α) is powered by a Cummins QSL9-AI, a 4-cycle, 6-cylinder diesel engine with turbocharger and air-to-air intercooler, delivering a maximum output of 276 kW (375 PS) at 1,900 rpm and torque of 1,491 Nm at 1,500 rpm. The engine is compliant with Japan’s 2011 emission standards for special vehicles and features automatic DPF regeneration during both travel and lifting operations. To support eco-friendly and cost-efficient performance, the crane also includes a fuel consumption monitor, “Eco Mode” to reduce unnecessary engine rpm, and “Positive Control” which adjusts hydraulic pump flow based on operating demand.

The crane’s mobility is supported by a switchable 4WD/6WD drive system with full-floating axles, allowing it to adapt to various terrain conditions. It has a maximum traveling speed of 49 km/h and a minimum turning radius of 7.5 meters in 8-wheel steering mode. The suspension is a fully hydraulic pneumatic type, and the braking system includes hydro-pneumatic disc brakes and magnetic auxiliary braking with retarder. Safety is a strong focus for this model, featuring Tadano’s AML (Automatic Moment Limiter), swing lock, suspension lock, emergency steering, and multiple alarms for over-speed, over-winding, and engine conditions. It also comes with standard equipment like winch and rearview cameras, AML warning lamps, and boom/jib monitoring systems.

In terms of lifting operation, the crane includes high-speed hoisting driven by hydraulic motors with two-speed winches. The boom and jib elevating systems use dual-acting hydraulic cylinders with pressure-compensated valves for smooth, accurate control. The slewing system is driven by hydraulic motor and ball bearing race, with a slewing angle of 360° continuous and a rotation speed of 2.1 rpm.

The GR-700N (G3α) also integrates Tadano’s HELLO-NET telematics system, which allows for GPS-based monitoring of crane location and operating data. This platform can be accessed through a web browser to view crane condition, maintenance schedules, and service history—though availability may vary by country.

Operator comfort is well addressed with a spacious, fully-equipped cab. It includes air conditioning, a tilting and telescopic steering wheel, a suspension seat with multiple adjustments, and a multi-function LCD monitor. Visibility is enhanced with wide-angle mirrors and optional side and rear monitoring systems.

Overall, the Tadano GR-700N (G3α) offers a well-rounded package of lifting power, environmental performance, operator comfort, and site adaptability, making it a reliable choice for demanding lifting operations in urban, industrial, and remote site conditions.
