The world-leading Wedgelock Quick Coupler is the flagship product of the Wedgelock range of attachments. It can be operated either hydraulically or manually.

Wedgelock Quick Couplers have a unique and constant locking principle. High strength construction increases wearability and reduces weight maximizing product performance and reliability. The Wedgelock low profile design ensures optimum breakout force and power at the bucket tip. Pin centre variations are accommodated automatically on both mechanical and hydraulic versions. Additionally, lifting eyes are fitted as standard ensuring safe lifting capability.
