Product feature: New Dyna couplers

Robur Attachments have given their coupler range a makeover and, in the process rebranded to a name that, they say, better reflects the hardworking, reliable, and powerful attachments

DynaMax coupler offers maximum tilt

Tilt buckets used to be the go-to solution, but now it’s said around 70% of new excavators being sold in New Zealand are fitted with a tilting coupler. Robur Attachments say their Dyna range has something for everyone, available in sizes to fit excavators from one to 50 tonnes or more and at a price range to fit most budgets.

"Dyna means ‘power’, and as in the case of ‘dynamic’, it’s full of energy, power, and motion. This describes our couplers perfectly," says Robur director Clem Simpkin.

"They are built tough, from high-quality steel and components, and have reliable power to attach any attachment securely, and the tilting couplers will hold their tilt angle even in the toughest of digging conditions."

DynaTough tilt coupler

The DynaTough Tilt coupler features two powerful hydraulic rams

The DynaTough is a twin-ram tilting coupler. The two rams allow tilt action up to 45 degrees in either direction. The squat design maximises the breakout force, and hydraulic hoses are well protected within the coupler, so there’s minimal risk of damage even when tackling the rough stuff.

Robur says it’s the only tilt coupler on the market that can safely be used with a rock breaker with no risk of premature wear or damage to the internal components.

DynaMax tilt coupler

The DynaMax provides a maximum tilt (thanks to the helical tilt actuator) of up to 90 degrees in either direction. The narrow design makes the coupler an ideal choice for trenching or working in confined spaces, and all hoses and fittings are well protected within the coupler. The high torque actuator offers maximum power and holding force and a smooth precise tilt.

DynaGrip coupler

Robur’s DynaGrip coupler is a double-locking, non-tilting quick coupler. It’s the same premium quick-hitch base as their other couplers with multi-fit and is designed to grip tight to any attachment, holding it safe and secure. The DynaGrip Coupler is available to suit excavators from two to 50 tonnes.

Robur says all their hydraulic couplers are compliant with current and proposed New Zealand and Australian safety standards. The couplers are designed with an option to operate at pilot pressure. This means on excavators fitted with a low-pressure hitch pilot circuit, operators can operate the coupler without compromising safety or functionality.

This feature saves time and money by not needing to adapt the existing hydraulics. "While the Dyna-coupler name might be new, the actual attachments have been around for many years, proven as the toughest in the field, time after time," says Clem.

"We know they get the job done and having sold thousands of couplers over the years, we know our customers also agree. Stay tuned for more Dyna couplers to join the family soon."
