Tadano expands its crane offering in Europe by launching three new rough terrain crane models – the GR-700EX-4, GR-900EX-4 and GR-1000EX-4 – featuring long boom designs with high lift capacities reaching 70, 90 and 100 tonnes, respectively. Their compact design includes a low overall height to improve transport ease. Flexibly working on both paved and rough, unpaved terrain, these cranes are the right choice for congested construction sites, maintenance work, industrial, energy and crane rigging assist applications.
These new Tadano rough terrain cranes boast round tubular boom construction to increase rigidity and deliver fast boom extension. They offer two synchronized telescoping system options that shorten extension time to maximum boom length to under three minutes for all three cranes. Their 2-stage, bi-fold lattice jib increases lifting flexibility by extending boom length by 10.1 or 17.7 m and 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.
All models are equipped with the Tadano View System, which combines cameras and sonar to support the crane operator during handling. Right front and rearview cameras help to increase work area visibility for the operator while driving. The operator conveniently monitors wire rope winding from inside the cab with the new standard winch drum monitoring camera. Integrated into the frame for protection, the rear “Clearance Sonar” can detect obstacles behind the crane and provides audible and visual alerts when an object is detected.
Camera feed are displayed on the new large 264-mm Multi-Function Display touchscreen, which can display lift charts, crane configuration and operating settings. “Clearance Sonar” alerts are displayed on a dedicated display which sits on top of the Multi-Function Display. The pressure-sensitive screen allows operators to quickly navigate through menus and change settings, even while wearing gloves. The reconfigured instrument panel puts all controls within easy reach to advance ergonomic operation, while a lower panel height improves visibility to the front of the crane.
To maximize full lifting potential, the new crane line features Tadano’s Smart Chart control system technology that evolved from 30 years of field application of asymmetric outrigger control systems. Whether working with asymmetric or fully extended outrigger positioning, this Tadano system expands the working area from a standard circular cone to a square pyramid. On congested jobsites where outriggers cannot be fully extended, Smart Chart adapts lift capacity, based on boom and outrigger positioning, in a comfortable work environment.
Both the new 90-tonne GR-900EX-4 and 100-tonne GR-1000EX-4 feature Tadano’s exclusive Smart Counterweight system to increase crane flexibility and lifting performance. Front and rear counterweight position options allow the crane to be rigged for either a compact tail swing radius or higher lifting capacity. The new system increases crane lift capacity by up to 22% and all “Smart” lift charts are visible on the in-cab display. Self-rigging capability of the counterweights reduce crane set-up time at the jobsite.
