Product catalog summary

General Data:
The Tadano Rough Terrain Crane, Model GR-700EX, has a lifting capacity of 70,000 kg at a 3.0 m radius. It features a 5-section boom with a maximum length of 44.0 m and jib lengths of 9.9 m and 17.7 m. The crane's dimensions are 14,570 mm in length, 3,513 mm in width, and 3,800 mm in height, with a gross vehicle mass of 48,955 kg.

Performance:
The crane can reach a maximum speed of 20 km/h and has a gradeability of 112% at stall. The boom elevation ranges from -2° to 80°, with a raising speed from 20° to 60° in 39 seconds.

Crane Specifications:
The boom is constructed as a round hexagonal box with 7 sheaves at the boom head. It includes a synchronization system with 2 telescope cylinders and cables. The main winch has a single line pull of 54.9 kN and a speed of 143 m/min, while the auxiliary winch has a speed of 125 m/min.

Hydraulic System:
The hydraulic system includes 2 variable piston pumps and a tandem gear pump, with multiple control valves and an air-cooled oil cooler. The hydraulic oil tank capacity is approximately 740 liters.

Carrier Specifications:
The crane is powered by a MITSUBISHI 6M60-TLU3B engine, delivering 200 kW. It features an electronically controlled full automatic transmission with 6 forward and 2 reverse speeds, and a steering system with four modes.

Brake System:
The service brakes are air over hydraulic disc brakes on all wheels, with a spring-applied air-released parking/emergency brake.

Equipment:
Standard equipment includes an automatic moment limiter, winch automatic fail-safe brake, and safety features like a hook safety latch and emergency engine stop system. Optional equipment includes a 70 t capacity hook block and an electric fan.

Rated Lifting Capacities:
Detailed tables provide rated lifting capacities under various conditions, including different boom lengths and jib offsets, with outriggers fully extended or at different extensions, adhering to EN13000 standards.

Operational Notes:
Operational guidelines emphasize setting the crane on a firm, level surface and the importance of outrigger extension width on lifting capacities. 'Creep' operations are restricted to 60m in 30 minutes at speeds below 1.6 km/h.

Working Range and Conditions:
Diagrams illustrate the working range, showing lifting height versus radius for various boom lengths. Adjustments should be made for boom deflection under load.

Additional Equipment and Modifications:
Details on additional equipment such as hook blocks and counterweights are provided, along with their impact on weight distribution. Instructions for removing or adding components to adjust the crane's configuration are included.
