Merlo CDC - Dynamic Load Control system; a new "State of the Art"

Merlo's revolutionary CDC - Dynamic Load Control system automatically combines attachment and telehandler to ensure best performance and safety - a new "State of the Art" for the industry!

European Technical Standard EN15000 was introduced in late 2010, with the aim of decreasing the possibility of forward overturns. Unfortunately, the solutions implemented by most of the manufacturers impacted in the way the units could be operated, limiting some of the typical operations carried out on farms.

Now, Merlo designers have used their ability for in-house design of electronics and matched Merlo attachments to Merlo machines in a unique way that gets the very best out of both - automatically!

Launched at Agritechnica 2011 will be the new Merlo CDC- Dynamic Load Control system - which for the very first time provides Automatic Implement Recognition when Merlo attachments are used with a Merlo telehandler.

All future attachments produced at the Cuneo factory will incorporate a recognition sensor. When the attachment is connected to the hydraulically-powered fork carriage, the patented CDCsystem automatically recognises the attachment type, displays a little icon on the cab display, and sets an internal 'load chart' specifically matching that attachment to that telehandler.

The system measures boom angle, boom extension and loading, and works out the position of the load in space. It compares the position and load with the virtual 'load chart' and calculates the 'stability index' - simply, how much of the available stability is being used.

The display shows the geometrical position of the load, digital readout of load, extension, actual load, the maximum permitted load and stability index. It doubles up the stability information with a vertical row of ascending LED's.

So, there can be no complaint about a lack of information! As the stability index approaches a pre-set figure, an alarm sounds and, finally, further aggravating motion is halted before the 100% index is reached, preventing a frontal overturn.

The CDCsystem also measures and controls boom descent speed, to prevent a frontal overturn being triggered by the boom motion being suddenly locked.

 

Attachments without recognition sensor 

Older Merlo attachments, and those from third-party suppliers, will not have a recognition sensor. In this case, the operator can select one of three settings, based upon the length of the attachment load centre from the carriage. Simple attachments, such as grabs, would be relatively short (say 500mm load centre), whilst specialised ones like bale shakers would be longer.

Whichever is chosen, the CDCsystem works in just the same way, but is an approximation of the best load chart, rather than one exactly tailored to the attachment. The driver is protected from making an incorrect choice by hub monitors that prevent frontal tip-over. Clearly, the system is designed to make the most out of the combination of Merlo machine and Merlo attachment.

Digging mode 

The biggest limitation for farmers following the introduction of EN15000 was reduced digging ability, as the telehandler is prevented from lifting the rear wheels (usually unless the boom is fully retracted).

The Merlo CDCsystem incorporates a 'Free Working Zone' which permits full power digging inside a specific zone, close to the ground where there is no risk associated with a forward tip, allowing the use of the machine's full potential!

When is the CDCsystem available? 

The two top Turbofarmer models - P40.7 CS and P37.10 CS - which also incorporate suspended cabs, are fitted with the CDCsystem already, with the other Turbofarmer models expected to be included by Q2 2012.
