Bottom: Thickness 12-20 mm, Hardness 350-500 HB

Component Specifications

Definition

The bottom of a bucket is a critical structural component in earthmoving and material handling equipment, designed to withstand abrasive forces, impact loads, and continuous wear during digging, loading, and dumping cycles. It typically features reinforced construction, wear-resistant materials, and may include replaceable wear plates or liners to extend service life and maintain operational efficiency.

Working Principle

The bottom component functions as the primary contact surface with materials, distributing loads across the bucket structure while resisting abrasion and deformation. It works in conjunction with the cutting edge and sidewalls to form a cohesive unit that optimizes material retention, penetration, and discharge during excavation or loading tasks.

Materials

High-strength steel (e.g., Hardox 400, AR400, or equivalent abrasion-resistant steel), thickness typically 10-25mm depending on bucket size and application. May include welded-on wear plates or hardfacing overlays for enhanced durability.

Technical Parameters

Parameter	Typical range	Notes & selection driver
Hardness	350-500 HB
Thickness	12-20 mm
Wear Life	2000-5000 operating hours under normal conditions
Weight Capacity	Varies by bucket size (e.g., 0.5-5 tons)

Frequently Asked Questions

What are the signs of bucket bottom wear that require attention?

Visible thinning, cracks, holes, or significant material loss exceeding 30% of original thickness indicate the need for repair or replacement to prevent structural failure.

How often should bucket bottom wear plates be replaced?

Replacement intervals depend on material abrasiveness and operating hours; typically every 1500-3000 hours in abrasive conditions, with regular inspections recommended every 250 hours.
