Component Specifications

Definition
The Back/Canopy is a critical structural component of a mining bucket that forms the rear wall and top enclosure. It serves as a protective shield for internal mechanisms and reinforcement against material impact during loading operations. This component typically integrates with side plates and cutting edges to create a complete bucket enclosure, designed to withstand extreme abrasion, impact forces, and material buildup in mining applications.
Working Principle
Provides structural support and containment by forming the rear and upper boundaries of the bucket cavity. Distributes operational stresses throughout the bucket frame, prevents material spillage during transport, and protects internal components from external damage. The canopy section specifically deflects falling debris during loading operations.
Materials
High-strength abrasion-resistant steel (AR400-AR500 grade), often with Hardox 400-500 series or equivalent. May include reinforced sections with wear plates or liners. Typical thickness: 25-50mm depending on bucket size and application.
Technical Parameters
  • Weight 500-3000 kg depending on bucket capacity
  • Hardness 400-500 HBW
  • Wear Life 3000-8000 operating hours
  • Dimensions Customized to bucket size (typically 2-6m width)
  • Mounting Type Welded or bolted assembly
Standards
ISO 21873, DIN 22261

Frequently Asked Questions

What is the primary function of the back/canopy in a mining bucket?

It provides structural integrity to the bucket's rear section, contains material during loading, and protects against impact from falling rocks during excavation operations.

How often should mining bucket back/canopy components be inspected?

Visual inspections should occur daily, with detailed thickness measurements every 250-500 operating hours depending on material abrasiveness.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
