The Likufix line of quick coupling systems is now sold under the brand name Solidlink.

Liebherr will now market its Likufix line of quick coupling systems under the brand name Solidlink.

The new branding for the system was introduced at ConExpo in Las Vegas in mid-March. The time-tested quick coupling system delivers maximum efficiency and safety for customers for changing attachments. Solidlink is suitable for use with Liebherr excavators or with machines from other manufacturers.

An advantage of Liebherr‘s quick coupling systems is its versatile, manufacturer-independent application and combination options with a wide range of different earthmoving machines and attachments. 

“Solidlink is a brand name that will be readily understood globally. We would like to use this to continue to establish our fully automatic quick coupling system in the future,” explained Rudolf Arnold, sales director at Liebherr-Hydraulikbagger GmbH.

The fully automatic Solidlink quick coupling system allows attachments to be changed easily and conveniently from the driver’s cab at the touch of a button. It quickly and safely connects the machine to the attachment to form a powerful unit. 

“Solidlink increases the machines’ possible applications increasing its capacity by up to 90 per cent,” Arnold said. “The fully automatic quick coupling system therefore makes a significant contribution to both efficiency and safety on site.”

Liebherr’s former Likufix quick coupling system also guarantees safety, thanks to a whole host of features. Solidlink is hydromechanically mounted to deliver an ideal balance in all axes and degrees of freedom. As the attachment can be changed from the driver’s cab, the possibility of personnel being in the danger zone during the attachment change process can be ruled out. 

The quick coupling system’s proximity sensor also monitors the correct position of the attachment in the locking position. If the pins are extended during coupling without the attachment tool being connected to the quick coupler, the machine operator is alerted by a warning sound in the cab and a warning signal on the display. 

Furthermore, the two-hand control process means the machine cannot operate out of control during the coupling process and the safety risks this may create can be eliminated. 

The high strength of the system is due to a solid metal plate and recessed hydraulic couplings that prevent damage during the coupling process. An optional bracket on the coupling block also protects the hydraulic lines.

The quick coupling system will retain its Likufix brand name in German and French-speaking countries.
