The introduction of the new quick coupler wheel loader attachments is the latest expansion of the new Doosan Heavy Attachment range for the Europe, Middle East and Africa (EMEA) region.

“Offering a one-stop-shop approach for attachments and increased versatility for Doosan wheel loaders and excavators, the Doosan Heavy Attachment range has been designed to match key machine parameters and kinematics to ensure optimum performance, visibility, stability and safe operation at all times.  All of the attachments are designed, manufactured, tested and approved in accordance with current international standards,” says the company.

The new Doosan wheel loader quick couplers increase safety by enabling the operator to easily and quickly change attachments without leaving their cab.  Visual locking indicators, protected cylinders and ISO/DIS 13031.2 compliance provide a further guarantee of safety.  The independent auxiliary circuit on the quick couplers also allows full use of third or fourth functions for hydraulic attachments.

The new Doosan wheel loader quick couplers offer a robust construction with high-strength steel for extended lifetime in the toughest conditions.  The open frame design lowers the weight of the couplers and ensures maximum visibility for the operator, with compact dimensions that minimise machine capacity and breakout force losses.

Buckets are matched to the tipping loads of the wheel loaders for maximum stability and safe operation of the machines.  The design of the attachments is based on kinematics simulations which prevent collisions or kinematic lock-out and ensure the movement of the attachments is what is expected and is always completely under the control of the operator. The simulations also ensure forces are transferred correctly from bucket to the carrier to facilitate optimum loading, digging, crowding and dumping.  Critical bucket positions have been optimised to enhance digging and dumping performance.  In addition, the pallet fork attachments have been designed to ensure that the operator has excellent visibility of the tines in every area of operation.

The new quick coupler range complements the family of high quality pin-on bucket attachments for the Doosan wheel loader range.  The quick-coupler and pin-on buckets offer a combination of robust construction and excellent penetration capabilities, covering the full range of applications from light duty jobs to the most severe and arduous tasks.  The large number of sizes and bucket types – encompassing General Purpose, Heavy-Duty, Rock and Light Material buckets – ensures maximum versatility and efficiency.
