Operator Comfort


The crane cab provides improved livability and a more comfortable working environment. 

Air conditioner


Hot-water heater and air conditioning


Seat adjustment


Multiple seat adjustment positions for ease of operation


Adjustment of control lever stand


The control lever stand has a 3-stage adjustment feature.


Before you enter or exit the cab, or when  you complete the crane operation, set the control lever stand on the left to the stowing position.


The unlock lever is used by pulling to adjust for all positions of the control lever stand.


The control levers are smooth and responsive to the operators touch.

Automatic moment limiter [AML-C]
Cẩu địa hình Tadano GR-300EX-3
Tadano's AML-C is easy to use, innovative in design, displays important information to the operator and enables the operator to preset a custom working environment. For example, the AML-C shows the boom angle, boom length, load radius, operating pressure of the elevating cylinder, the extension width of the outriggers, slewing position, rated lifting capacity and present hook load. These features allow the AML-C to move seamlessly through all lifting operations without having to change configurations or input new codes to make the lift. The AML-C safety features provide both audible and visual warnings. When an operation approaches the load limit Tadano's slow stop function engages to avoid shock loads

Outrigger Asymmetric Extension Width Control


When operating the crane with the asymmetric outriggers extended, the AML-C detects the extension width of all of the crane's outriggers (front, rear, left and right) to measure maximum work capacity in each area. When slewing the boom from the longer outrigger area to the shorter outrigger area, the AML-C detects the motion and displays


The maximum capacity according to the extension width of each of the outriggers,and brings the motion to a slow stop before it reaches the maximum capacity. Therefore, even in the case of operator error, the AML-C's slow stop function will help to minimize any safety risk.

The Fuel Monitoring System, displayed on the AML-C screen, monitors fuel consumption rates during crane operations, idling, and while traveling, allowing the operator to optimize fuel efficiency, reduce CO2 emissions and noise level.

The Eco Mode System controls the maximum engine speed at the time of crane operation. To prevent an unnecessary rise in engine speed when there is excessive acceleration, the system enables fuel consumption and CO2 emissions to decrease by Max. 22% with Eco mode 1, and Max. 30% with Eco mode 2, and the noise level is reduced.

The Positive Control System effectively controls the quantity of hydraulic pump discharge during crane operation in response to the amount of movement applied by the operating control lever. When the crane is in a state of idling, the Positive Control System keeps the quantity of hydraulic pump discharge to a minimum, reducing fuel consumption and CO2 emissions by up to 20%.


Non-operating mode 


The mode keeps the quantity of hydraulic pump discharge to a minimum, which enables a considerable decrease in fuel consumption.


Operating mode


The mode enables the hydraulic pump to function effectively in response to the amount of movement the operating lever applies.

TADANO supports your crane management via the Internet, providing information about operational status, position and maintenance.


Monitoring machine information from your computer


1. Work History


HELLO-NET Owner’s Site displays the day-to-day operational status, mileage and remaining fuel for each machine equipped with a communication terminal. In addition, you can view a list displaying the number of hours of operation and the mileage of all your machines for any specified month.


2. Machine Position Data


Using HELLO-NET Owner’s Site, you can check a machine's latest position (up until the previous day) on a map. Two types of position data, listed below, are transmitted automatically from your machine once every day. Work Site: The location where the machine’s PTO has been activated (for one hour or more). Position at Day’s End: The final location from which GPS was able to receive data on a given day.


3. Maintenance Information


You can check the maintenance timetable of your machines for periodical replacement parts and inspection schedule. HELLO-NET supports the maintenance of your machine.


Telematics (machine data logging and monitoring system) with HELLO-NET via internet (*availability depends on the situation).


DETAILS: The availability of data communication systems, such as satellite or mobile communications which serve to widen the service area differs according to individual countries. Besides, there are some countries where the system itself is not in use yet. For details, please contact your distributor or our sales staff in charge.
