Lehnhoff at Komatsu Demo Days

Published: 28/12, 2023

For decades, Lehnhoff’s quick couplers and attachments for the construction and building machinery industry have been an integral part on German and European construction sites. Now, the German pioneer with more than 200,000 quickcoupler systems sold is crossing the Atlantic to establish itself in the US market as well. 

Lehnhoff showed off its capabilities at Komatsu’s Demo Days in Cartersville, Ga. The company’s SQ series of fully hydraulic quickcouplers impressed visitors with their performance, flexibility, and user-friendliness. 

Mounted on the 355 Komatsu PC360 hydraulic excavator, the SQ80V effortlessly changed between hydraulic attachments, such as hammer, grab and pulveriser, as well as the different buckets, such as the Lehnhoff HTL35 or the Lehnhoff HG35 SH, which were also presented. 

With a maximum oil flow of 145 gpm (550 lpm) per valve, the full power of the hydraulic attachments can be utilised. Thanks to the symmetrically arranged valve block, even hydraulic attachments can be picked up by 180 degrees, giving users completely new application versatility. And the particularly low-maintenance short-stroke valves make on-site maintenance much easier.

The SQ series’ compact, vertical valve system can be used safely and for a long time, especially in tough applications or at narrow angles. The particularly easy maintenance was also impressive during the demonstration. The valves can be replaced in less than two minutes in the case of service.
