Product Overview

The JRB DuraLatchTM multi-fit, twin locking hydraulic pin-grabber coupler is designed for a wide range of OEM attachment pickups on excavators from 8mT to 50mT. The coupler delivers exceptionally strong performance in easy to operate, lightweight, compact design. ISO 13031 compliant, DuraLatch features a twin locking system that keeps attachments securely engaged in the event of lost hydraulic pressure. 

 

Featured & Benefits

Fully cast body from high tensile steel, delivering exceptionally strong performance.

Fewer moving parts than typical couplers, with only 4 replaceable parts for easy maintenance: front latch, rear hook, latch actuator, cylinder.

ISO 13031 compliant twin locking back up system, including an internal gas spring cylinder which ensures the attachment remains securely engaged in a working position in the event of hydraulic loss.

Lightweight cast frame designed to reduce engine load delivering fuel economy without compromising on machine breakout force.

The low profile design delivers a shorter pin to tip measurement which delivers maximum breakout force for greater productivity and efficiency.

Optimized coupler arm design to mirror excavator geometry.

Significantly lighter than typical excavator couplers, in some cases up to 42% lighter* (NOTE: Weight savings based on comparable products. Relative weight dependent on range.).
