Product Description

Werk-Brau Coral Rock Bucket | Width 8"–36" | 1.0–11.3 Tons | For Mini Excavators & Backhoes

DESCRIPTION

The Werk-Brau Coral Rock Bucket is a heavy-duty excavator bucket engineered for the demanding “peeling” action required to dig coral rock. Built for mini excavators and backhoes, it also performs effectively in demolition, abrasive materials, shot rock, and moderate prying applications. High-strength, wear-resistant steel reinforces critical and high-wear areas, while the fully protected bucket bottom and reinforced wear plates help withstand severe digging conditions. The reinforced torque tube design helps prevent shell cracking during extreme digging and prying. Tapered side plates reduce side wear and improve material release for easier dumping. An extra-thick cutting edge and increased number of smaller teeth provide enhanced protection and extended service life. Available in multiple widths and capacities, this coral rock excavation bucket offers a durable solution for demanding earthmoving and construction applications.

Key Features

• Coral Rock Excavation Design Engineered specifically for the demanding “peeling” action required to dig coral rock and hard, irregular material.
• Heavy Duty Construction Built with high-strength, wear-resistant steel in critical and high-wear components for demanding excavation environments.
• Reinforced Torque Tube The reinforced torque tube design helps prevent shell cracking when the bucket is subjected to extreme digging and moderate prying forces.
• Extra-Thick Side Plates Heavy-duty side wear plates help resist abrasive lateral cutting and wear commonly associated with coral rock excavation.
• Protected Bucket Bottom Features an external double bottom and full-bottom wear plate to protect the bucket structure in high-wear applications.
• Tapered Side Plate Design Tapered side plates reduce side wear while helping excavated material release more easily during dumping.
• Reinforced Cutting Edge An extra-thick cutting edge is engineered for demanding digging conditions and increased resistance to wear.
• Increased Tooth Protection Additional smaller teeth protect the cutting edge while improving penetration through difficult coral rock and abrasive material.
• Heavy Duty Tooth System A heavy-duty tooth and adapter system is selected to accommodate coral rock’s irregular penetration characteristics.
• Multiple Tooth Options High-quality tooth options are available to suit different excavation requirements and operating conditions.
• Wide Size Selection Available in 8" to 36" widths across multiple mini excavator classes for flexible equipment matching.
• Multiple Bucket Capacities Rated capacities range from 0.78 cu. ft. to 17.1 cu. ft., supporting different material-handling requirements.
• Mini Excavator Compatibility Designed for Mini 05, Mini 76, Mini 1, Mini 15, Mini 2, Mini 3, Mini 4, and Mini 5 classes.
• Backhoe Compatibility Compatible with applicable standard backhoes, including the listed Mini 2 & U2 BH class configurations.
