The D-Lock Tilt Coupler allows operators to simply tilt all attachments rather than having to move the entire machine, improving productivity and versatility.

The D-Lock Tilt Coupler from Werk-Brau allows an operator to tilt the attachment instead of repositioning the excavator for enhanced productivity and versatility on each jobsite. 

The coupler’s compact narrow body allows better visibility and performance, while the triple-sealed power actuator allows trouble-free operation which is virtually maintenance-free. With up to 180-degrees of tilt, the D-Lock Tilt Coupler increases profitability by accomplishing tasks quicker with fewer excavator moves. A multi pin center picks up all attachments in the same weight class with the same pin diameter. Four hydraulic lines are required for installation, with no greasing or lubrication needed. These performance-boosting couplers are ideal for mini/compact excavators to 5-ton, and for full-size excavators to 35 MT. 

The unique design of the D-Lock Tilt Coupler includes safety features such as automatic front lock, dual pin locking, and a patented slide-lock design. The Automatic Front Lock feature locks the front pin in the event the rear pin is not secured. Each unit includes a highly visible front lock indicator. 

The Dual Pin Locking (DPL) safety system of every D-Lock Coupler locks both the front and rear pins in case of loss of engagement force, ensuring that attachments cannot swing on the front pin. 

The simple yet safe unlock procedure ensures that the unit releases only when intended, in a safe and controlled manner which prevents accidental release. The sliding jaw primary lock allows for multi pin centers to be accepted and is operated by a unique double-skinned, double-acting hydraulic cylinder utilizing full system pressure. No head feed tube or pressure reducer is required. The D-Lock Coupler fully complies to AS4772-2008 and EN474 Standard and the expected forthcoming ISO international standards.  

A new three-button coupler switch simplifies coupler safety and operation. The logic and sequence built into the switch ensures there will be no inadvertent activation. A two-tone alarm (intermittent buzzer for activation and solid buzzer for disengagement) and a light system alert the operator that he has sent a signal to the coupler cylinder to disengage. This allows simple, safe activation. A 5-second window allows the operator to complete the sequence or switch resets.  

The compact D-Lock Coupler complements Werk-Brau buckets and thumbs of all sizes and types. The company also manufactures tilt couplers in other styles including Manual Pin Grab, Pull-Pin/Half Hitch, Kubota Bantam, and the John Deere Wedge Tilt Couplers to suit a wide range of machinery and preferences.
