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 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.

The newly developed Smart Chart expands the working area, allowing you to get the best crane performance in any outrigger extension setup.

Tadano's new Smart Chart taps into a crane's full potential by expanding the rear part of the conventional circular work area into a square for increased load radius when the outriggers are extended to improve safety and efficiency.

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.
