1. Key Features & Benefits
-
Fast attachment switching – Change buckets, breakers, grapples and other tools within seconds without leaving the cab, dramatically reducing machine idle time.
-
Wide machine compatibility – Engineered for Hitachi EX200-1, EX200-2, EX200-3, EX200-5, EX300, EX350, EX370 excavators, plus direct fit for Komatsu (PC200/220/300/360), Caterpillar (E320/325/330), Kobelco (SK200/210) and Daewoo (DH220/280) models.
-
Twin safety locking system – Equipped with a wedge-style coupler that delivers a rattle-free, zero-play fit between coupler and attachment, plus secondary retention springs that keep the attachment locked even in the unlikely event of hydraulic pressure loss.
-
Heavy-duty construction – Fabricated from high-strength Q345B alloy steel (also available in cast steel design) for superior impact resistance and long service life under extreme working conditions.
-
Direct fitment – No modification required to your machine’s arm structure. Precision-engineered mounting points match OEM arm pin hole distances and widths exactly.
-
Hydraulic or manual versions – Hydraulic models for fully automatic in-cab operation; mechanical/spindle versions for simpler, cost-effective installation on machines without auxiliary hydraulics.
-
Fast delivery – 6–8 working days lead time from our Guangzhou warehouse.
