What is a “Twin Locking” Coupler?

Miller coined the phrase “Twin Lock” coupler, but what does it actually mean?

A Twin Locking coupler simply means that it has mechanical locks on both the front and rear attachments pins to ensure that they remain securely attached in the event of loss of hydraulic pressure or the operator accidently knocking the switch inside the cab.

This means that a secondary mechanical backup system is in place that is completely independent of the hydraulic circuit.

Our couplers also have hydraulic check valves in the solenoid and cylinder as standard.

A More Effective Coupler Design

During our extensive development, testing and field evaluation, we carried out detailed market research and asked you, our customers, how could we make the current quick coupler designs available more effective?

You asked us to…

MAKE COUPLERS EVEN SAFER

  • It’s a genuine ‘twin locking’ coupler.
  • The patented ABS (Automatic Blocking System) ensures that in the event of hydraulic failure, the PowerLatch, will automatically lock on both front and back pins, mechanically and independently of the hydraulic circuit.
  • Attachments can only be removed in a safe, curled position.

MAKE COUPLERS LIGHTER

The cast PowerLatch is considerably lighter, as is demonstrated in the factual weights (shown opposite), when compared against other brands listed within 20T category.

MAKE COUPLERS EVEN STRONGER

The PowerLatch is now approximately 20% stronger than comparative models (depending on machine tonnage category)

MAKE COUPLERS MORE COMPACT

The re-engineered PowerLatch design is more compact than previous Miller couplers.

PUT THE LIFTING EYE IN THE CENTER

The PowerLatch has a lifting eye in the center of the back plate whilst still being incorporated as part of the coupler casting for retained strength.

MAKE COUPLERS EASIER TO INSTALL

The ports that connect the hydraulic hoses to the coupler in the PowerLatch design have been moved to the top of the cylinder, making installation even easier.

MAKE COUPLERS EASIER TO SERVICE

The PowerLatch design incorporates wear indicators which provide all users with a guide for service and repair, in addition to the information set out in the manufacturers operating instructions and/or installation procedures.

MAKE COUPLERS VISUAL

The PowerLatch can be supplied with Miller Mate (Coupler Alert Safety System) which provides the operator with an illustrated step by step operational guide, as well as a visual warning light and an audible alert message signalling to operator and all site workers, the coupler is detached.

In Summary, the PowerLatch coupler is;

  • LIGHTER
  • STRONGER
  • SAFER
  • TWIN LOCKING
  • EASIER
