ESCO Hydraulic Coupler

Staff | September 28, 2010

ESCO Corporation's new TwinLock™ Hydraulic Coupler can pick up a full range of OEM buckets within a machine's weight class.

The new coupler is designed for improved performance and safety. It has a cast body for performance and increased life over fabricated couplers. The design includes two key locking features that increase safety. The front latch acts as the first locking mechanism and is visible to the machine operator. The second locking mechanism is two gravity-operated mechanical locks that secure the attachment in the event that hydraulic pressure is lost.

Other benefits: The Coupler can be operated directly from the machine's cab without need for the operator to manually insert a pin; front latch serves as a backup locking mechanism and a visual indicator when the hydraulic cylinder has retracted; front retaining jaw catches the front pin in the event the hook is not fully engaged on the attachment pin, ensuring attachment retention; cast couplers are available for 7- to 40-ton excavators, with increased strength and less weight at the end of the stick than with fabricated couplers.
