Custom Excavator Bucket Combines Design and Performance

Liebherr Indonesia has supplied a custom 20 m³ excavator bucket to Darma Henwa for use at the Bengalon mine in East Kalimantan. The attachment, installed on an R 9350 mining excavator, combines site-specific performance requirements with a customized design reflecting the customer’s corporate identity.

Engineering for Heavy-Duty Mining Applications
The bucket is designed for large-scale excavation tasks typical of open-pit mining operations. With dimensions of approximately 3.4 meters in height and 3.6 meters in width, the attachment supports high-volume material handling while maintaining structural integrity under continuous loading conditions.

Such buckets must withstand abrasive materials, high impact forces, and repetitive loading cycles. Design considerations include wear resistance, load distribution, and compatibility with the excavator’s hydraulic system to ensure efficient digging and material transfer.

Customization Without Compromising Performance
The project originated from Darma Henwa’s requirement to incorporate its updated corporate identity into operational equipment. Liebherr Indonesia’s fabrication team developed a customized solution that integrates visual design elements without affecting the bucket’s functional performance.

Close coordination between engineering and customer teams ensured that the final product met both aesthetic and technical specifications. Despite the customization, the bucket maintains the durability and reliability required for mining environments.

Fabrication and Delivery Timeline
The bucket was designed, manufactured, and delivered within a 12-week timeframe. This required synchronized planning across design, fabrication, and installation stages to ensure alignment with operational schedules at the Bengalon site.

Rapid turnaround is particularly important in mining operations, where equipment availability directly impacts productivity and output.

Integration into Mining Operations
Following installation on the R 9350 excavator, the bucket is used in routine excavation activities. Its capacity supports efficient material movement, contributing to overall site productivity.

The integration of customized equipment into daily operations demonstrates the ability to adapt standard mining components to specific customer requirements while maintaining operational efficiency.

Relevance for Mining Equipment Development
The project reflects broader trends in mining equipment design, where functionality remains the primary requirement, but customization is increasingly used to align with corporate branding and operator preferences.

At the same time, maintaining performance standards is critical, particularly in high-demand environments where equipment reliability directly affects operational continuity. Combining engineering precision with adaptable design enables manufacturers to meet both operational and customer-specific requirements within modern mining workflows.
