Tadano GR-1000XLL-4, GR-1000XL-4, and GR-800XL-4 rough terrain cranes are upgrades in the 75 to 100-ton lifting class. They are powered by a 280-horsepower Cummins B 6.7 diesel paired with a six-speed transmission.
The GR-1000XLL-4 features a longer boom than its predecessor, the Dash 3 version, measuring 167.3 feet. The Smart Counterweight system enables the operator to use two counterweight positions to increase lifting capacity.
The GR-1000XL-4 carries the same model features as the GR-1000XLL-4, but with a 154.3 feet boom.
The GR-800XL-4 has an upgraded maximum lift capacity of 80 tons and a boom of 154.2 feet. Gross vehicle weight is 99,800 pounds.

A winch drum monitoring camera checks the winding state of the wire rope when the crane is in operation. Cameras have also been installed on the right-front and rear of the crane ensuring visibility while driving. “Clearance Sonar” detects obstacles right behind the crane. A buzzer and a flashing icon on the display notify the operator if an obstacle is detected.
The cab instrument panel shape, height, and angle of the glass face have also been modified, improving visibility from the driver's seat. All three models feature the new 20-degree cab tilt function, which helps to reduce operator fatigue when operating the crane for long periods of time.
The GR-1000XLL-4 and GR-1000XL-4 are the first RT cranes to have the “Smart Counterweight” system that enables the counterweight to have two mounting positions. This feature increases the load chart by up to approximately 20 percent. Tadano’s proprietary "Smart Chart" is also on-board, allowing the crane’s work performance to be maximized.
The cabs have been redesigned for improved operability and visibility. The 10.4-inch multifunction color touch panel display contains crane work information and operation settings. The pressure-sensitive touch panel display allows operation while wearing gloves.
