Tadano has expanded its crane offering for the European market with the launch of a new line of rough terrains, comprising three models.

The versatile new Tadano GR-700EX-4, GR-900EX-4 and GR-1000EX-4 feature long boom designs with maximum capacities of 70t, 90t and 100t respectively.

They feature a round tubular boom construction, which the manufacturer says increases rigidity and delivers fast boom extension. Two synchronised telescoping system options, shorten extension time to maximum boom length to under three minutes for all three cranes. Their two-stage, bi-fold lattice jib extends boom length by 10.1m or 17.7m, offering offset positions of 3.5°, 25° or 45° from the main boom centerline. “Assist cylinders provide fast and simple jib installation, and it conveniently stows along the base boom section when not in use,” added Tadano.

The 100t GR-1000EX-4 has a maximum boom length of 51m, which the manufacturer says is class leading. Through the synchronized telescopic boom system, the maximum boom length can be extended in 170 seconds. Its two-position Smart Counterweight system increases lifting capacity at a 42m radius from 0.9t in the forward position to 1.1t at the rear position when equipped with its full 11.2t of counterweight. This model has an overall height of 3,805mm, length of 15,185mm and width of 3,315mm.

The 90t class GR-900EX-4 comes with 9.1t of counterweight that can be quickly self-rigged by the crane. With its two-position Smart Counterweight system, it offers a 1t lifting capacity at a 40m radius with the counterweight in the forward position and 1.2t capacity at a 40m radius in the rear position. The 47m maximum boom length can be deployed with synchronised boom extension of the third, fourth and fifth sections to a 35m length in 155 seconds.

The GR-700EX-4 offers 70t capacity at 3m radius and has a boom length of 47m. The crane quickly extends to a 35m boom length in 142 seconds. A 4.35t counterweight package is integrated into the upper carriage. It has a compact design; with an overall length of 14,375mm, an overall width of 3,315mm and overall height of 3,820mm. Tadano also highlighted its compact tail swing which makes it suitable for work in tight spaces.

A six-cylinder Stage V-compliant 209 kW engine powers the new cranes with maximum 1,152 Nm of torque. All models are equipped with the Tadano View System, which combines cameras and sonar to support the crane operator during handling. Camera feed is displayed on the new large 10.4in Multi-Function Display touchscreen. Tadano’s Smart Chart control system technology is a feature of all three, while the GR-900EX-4 and 100-tonne GR-1000EX-4 also feature the Smart Control system.

Entry into the re-designed cab has been simplified with a new three-step, angled extension ladder and door design that aligns with the steps. The crane’s new catwalk on the cab permits entry at any slewing angle.  Tadano says a 20° tilting function aids in reducing operator fatigue when working longer shifts. The cab also has an improved HVAC system.

The new crane series electronically controlled, fully automatic transmission offers six forward speeds – three high/low – and two reverse speeds to meet underfoot driving conditions. Four-wheel drive in both forward and reverse allows these cranes to navigate rough, hilly terrain. The cranes offer a maximum 18km/h forward travel speed.

The new Tadano rough terrain crane line is standard equipped with Hello-Net telematics service. Tadano’s smartphone app, Hello-Data Link, connects the crane to mobile devices for convenient access to real-time crane data.

“While offering powerful performance, the crane line’s newly developed pump disconnect feature automatically stops the crane’s hydraulic pump after idling for a set period to reduce fuel consumption. Standard Fuel Monitoring System, Eco-Mode and Positive Control help to further improve fuel consumption, reduce CO2 emissions and operating noise to advance environmentally friendly operation,” Tadano added.
