DOOSAN Infracore Construction Equipment has extended its range of attachments for excavators with a new line of heavy-duty buckets and quick couplers manufactured in Europe.

The new attachments, which are intended for all markets in Europe, Middle East and Africa (EMEA), can be mounted quickly and easily, providing cost-effective and productive solutions for a number of applications, including digging, trenching, loading, mining and quarrying, says the manufacturer.

Available in a variety of sizes, the new attachments are approved for use on Doosan excavators from 14 to 70 tonnes. Each size of attachment is said to be engineered in accordance with the specifications of the matching Doosan excavator to ensure the highest performance, efficiency and stability.

“With the introduction of the new bucket and quick coupler range, customers benefit from an extended one-stop-shop approach for carriers, attachments and parts from Doosan, available via its comprehensive Doosan dealer and service network in EMEA,” says a Doosan official.

Engineering approval of every attachment product ensures optimised performance of any combination of excavator and attachment. “The compatibility of the new Doosan attachments with Doosan excavators avoids operational issues that may arise from using non-approved attachments,” says the official.

Furthermore, with the quick couplers, operators can change attachments comfortably from within the cab, saving up to 25 per cent of total machine operating time compared to a direct mount system. The coupler design matches the excavator to the bucket to ensure optimum rotation and digging performance. “Its unique design offers productivity, versatility and, most importantly, safety during operation and attachment changing,” he says.

Also, heavy-duty grading buckets are available for excavators ranging from 14 to 30 tonnes. “The grading buckets have formed diamond folded top sections for additional strength with wear straps, weld-in cast side cutters and two web plates for extra rigidity. The slim design of the bucket web plates provides more space for easier transport, while their deep profile makes them ideal for levelling and loading applications,” the official adds.

The new attachment range includes a series of heavy-duty construction buckets covering all Doosan excavator models from 14 to 70 tonnes. The buckets are designed for general construction site work as well as for use in more demanding excavating conditions. They have a cast corner section and side cutters for increased protection against wear and tear, and are suitable for digging soil, dirt and light gravel.

Meanwhile, the range of rock digging buckets designed for Doosan excavators from 14 to 52 tonnes is intended for tough overburden digging applications in compacted surfaces and for abrasive material such as earth/rock, sand/clay and sand/gravel mixtures. The rock buckets have a heavier cutting edge and teeth for increased strength. Highly abrasion-resistant materials and added reinforcements in critical areas provide maximum reliability and long life.

Additional bottom straps increase resistance to wear. Other features include highly abrasion-resistant materials and reinforcements in critical areas for maximum durability. Extra high side plates provide greater strength and wear resistance in demanding applications.
