excavator manual quick coupler
Doosan has released the wedge lock coupler for use with the company’s 6- to 53-metric-ton crawler excavators. This new attachment expands the Doosan coupler line, which currently includes the hydraulic quick coupler.
The new wedge lock coupler manual mounting system is approved for use with 13 crawler-excavator models including the DX63-3, DX85R-3, DX140LC-3, DX140LCR-3, DX180LC-3, DX225LC-3, DX235LCR, DX255LC-3, DX300LC-3, DX350LC-3, DX420LC-3, DX490LC-3 and DX530LC-3.
The wedge lock coupler allows operators to change their excavator attachments without the need for additional hydraulics, but does not decrease a machine’s breakout force. The new coupler has a limited increase in tip radius over pin-on mounting.
Hydraulic Quick Coupler Excavator
The versatile wedge lock coupler is designed to allow for the use of multiple attachments, such as Doosan’s line of heavy-duty digging buckets. It also mounts the company’s current offering of trenching buckets and is capable of efficiently releasing high-capacity bucket models. The new coupler will also pair with Doosan’s excavator clamp attachments.
In an effort to increase jobsite safety, the wedge lock coupler’s swing ear design and the use of a bolt retainer safety plate helps prevent attachments from falling.
What is a hydraulic coupler on an excavator?
A hydraulic quick coupler, also called the hydraulic quick connect or quick change, is a device that enables the operator to switch back and forth between buckets and attachments from the comfort of the cab.
How Do I Identify A Hydraulic Coupler?
Factors to Consider When Identifying Hydraulic Quick Couplers. The main elements that can help to identify a quick-release coupling are the stampings that may be present on the surface of the coupling (name or logo of the manufacturer and part number) as well as its profile and dimensions.
