Werk-Brau has introduced the D-Lock tilt coupler. The tilt couple enables operators to tilt the attachment directly instead of repositioning the excavator. This leads to increased productivity and versatility on each job site. A compact and narrow body allows better visibility and performance. Werk-Brau says that a triple-sealed power actuator allows for trouble-free operation. With up to 120 degrees of tilt, the D-Lock tilt coupler quicker tasks with fewer excavator moves. The coupler is ideal for excavators starting from 5 to 35 tonnes.
Werk-Brau's new tilt coupler utilizes an automatic front lock, dual pin locking, and a slide lock design. A dual-locking design helps ensure that attachments remain securely engaged on both pins in the event of loss of engagement force. The unlock procedure ensures that the unit releases only when intended to, in a controlled and safe manner that prevents accidental releases. A multi-pin centre picks up all attachments in the same weight class with the same pin diameter. Just four hydraulic lines are required for installation, with no greasing or lubrication needed.
Each unit includes a visible front lock indicator. An automatic front lock feature locks the front pin in the event the rear pin is not secured. The sliding jaw primary lock allows for multi-pin centres to be accepted and is operated by a double-skinned, double-acting hydraulic cylinder utilizing full system pressure. No head feed tube or pressure reducer is required. The D-Lock coupler complies with AS4772-2008 and EN474 Standard and expected forthcoming ISO international standards.
Every D-Lock coupler includes a dual-pin locking (DPL) system. The front lock automatically engages the moment the rear jaw is activated, negating any chance of the bucket falling off if the operator misses the rear pin. DPL safety system locks both front and rear pins in the event of loss of engagement forces and helps ensure that attachments cannot swing on the front pint in the event of loss of engagement forces.
A new three-button coupler switch simplifies coupler safety and operation. The logic and sequence built into the switch ensure 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 safe activation. A five-second window allows the operator to complete a sequence or switch resets.
