The ESCO TwinLock™ hydraulic coupler is the latest design for improved performance and safety. The cast body ensures performance, with a significantly increased lifespan compared to fabricated couplers. The TwinLock design includes two key locking features that provides among the greatest safety in the industry. The front latch acts as the first locking mechanism and is visible to the machine operator. The second locking mechanism is comprised of two gravity-operated mechanisms that secure the attachment in case hydraulic pressure is lost.

• Can be operated directly from the machine’s cab without requiring the operator to manually insert a pin.
• Two gravity-operated mechanical locks secure the coupler hook in position in case of hydraulic pressure loss.
• The front latch acts as a backup locking mechanism and provides a visual indicator when the hydraulic cylinder has retracted.
• The front retaining jaw catches the front pin in case the hook is not fully engaged on the attachment pin, ensuring attachment retention.
• The universal design allows for a full range of OEM buckets within a machine’s weight class.
• Cast couplers are available for 7- to 40-ton excavators, with greater strength and reduced weight, compared with a fabricated couplers, at the end of the stick.

Use of hydraulic couplers has increased dramatically in the last 20 years. The ESCO Multi-Pin Grabber™ coupler offers all the advantages of a standard coupler with added versatility – allowing operators to pick up a variety of attachments lugged for other excavator brands within the same weight class. The Multi-Pin Grabber coupler offers operators broader use of attachments inventory than ever before.

ESCO offers the Scoop bucket system in conjunction with the Multi-Pin Grabber Coupler. The unique design incorporates the attachment pins into the bucket beam, which maintains maximum break out force and provides all the advantages of a hydraulic coupler.

• Buckets can be picked up in either the backhoe or face shovel mode for increased machine versatility – and added profits.
• Hydraulic Check valve in the cylinder retains hydraulic fluid in cylinder for added attachment security and safety.
• The mechanical safety lock provides added security.
• Retains the same bucket open and close geometry for maximum break out force, which means machine efficiency.
• Hydraulic kit utilizes full system pressure to prevent any movement and associated wear, which means longer duty cycles.
• Closed lifting eye means added safety for your crew.
• Fully FEA tested and manufactured to ISO 9001 standards
