Lehnhoff Fully Automatic Symmetric Quick Couplers

The Lehnhoff® SQ-V Fully Automatic Symmetric Quick Couplers, distributed in North America exclusively by Montabert®, provide improved efficiency, productivity and versatility for demolition contractors—especially when combined with Montabert Silent Demolition Tools.

Lehnhoff offers quick coupler models for 8- to 70-ton excavators, allowing operators to change all hydraulic attachments quickly and automatically without leaving the cab, which increases their efficiency and safety. Advantages include potential savings in additional excavator and operator costs, increased productivity with less time spent on manual attachment changes and reduced safety risks for the operator by not unhooking hydraulic hoses with each attachment change.

These innovative quick couplers are compact, versatile and robust. A standardized interface with two coupling shafts enables rigid attachments to be rotated by 180 degrees, meaning a bucket can be used as a backhoe or as a shovel bucket. It is also well-suited for tiltrotator applications. Lehnhoff’s LSC safety assistance system provides full control over all quick coupler operating conditions, immediately detecting any locking issues so the driver can react. With patented valve technology, the SQ-V line comprises a fully hydraulic system that protects machines, attachments and hoses.

The Lehnhoff Hartstahl GmbH has developed into a market leader in the design and manufacturing of attachments for excavators. With a large range of tools for every type of excavator, Lehnhoff offers innovative products for construction, road building, demolition and recycling, gardening and landscaping, as well as aggregate operations. The company’s full range of quick couplers is designed for backhoe and tilting buckets, demolition and special equipment in every category. For more information about Lehnhoff, visit lehnhoff.com.
