Lehnhoff SQ Quick Coupler

FEATURES

• Quick coupler valve block and corresponding adaptors can be configured to accommodate any hydraulic attachment.  The symmetrically arranged short-stroke valves provide maximum flow and include a hydraulic tensioning device to ensure firm connections, an integrated case drain line, and an optional electrical feed through (EF). The symmetrical design of the valve block also allows for mounting of buckets in standard or shovel mode.
  
• Designed as fully automatic systems (the quick coupler is also available without valve technology)
• Complements the symmetric concept of the S-standard (the open industry standard for the interface between excavator and attachment) with an ingenious feature: a symmetric valve block that allows attachments such as a tilting bucket or a crusher bucket to be operated hydraulically in shovel mode
• Built-in protection function prevents misdirected engagement with attachments not intended for reverse mode
• Engineered internal block depressurization unit increases the service life of the SQ valves and reduces the installation efforts and costs significantly.
• Lenhnhoff-Safety-Control (LSC) offers control of all operating states of the quick coupler from the driver’s cab. If LSC detects a faulty connection, it will display a warning so the operator can take action.
