The Rock Bucket for the 6040 Hydraulic Mining Shovel is specifically designed to maximize productivity in the harshest mining environments. Built for durability, efficiency, and precise material handling, this high-performance bucket ensures minimal downtime and optimal load management when working with tough, abrasive materials such as granite, quartzite, and iron ore.
一.Rock Bucket Features
Heavy-Duty Construction
Reinforced with high-strength alloy steel and extra wear-resistant components to withstand extreme impact and abrasion.
Optimized Bucket Geometry
Designed for fast fill and easy material release to enhance cycle times and reduce fuel consumption.
Replaceable Wear Parts
Equipped with easily replaceable GET (Ground Engaging Tools) such as adapters, teeth, and wear plates to extend bucket life and minimize maintenance downtime.
High Capacity
Standard capacity ranges from 14.0 to 16.5 cubic meters (18.3 to 21.6 cubic yards), with custom sizes available upon request.
Welded and Cast Components
Combines cast steel components in high-stress areas with robotically welded seams to ensure structural integrity.
二.Parts for Rock Bucket
1. Bucket Front (or Bucket Face)
🔹 Function:
The bucket front is the leading surface that first engages with the ground or material. It is responsible for initiating cutting, breaking, or scooping action and is subjected to high impact and abrasion.
🔹 Structural Features:
Usually curved or sloped to optimize material flow.
Reinforced with wear plates or liners.
Integrates closely with the cutting edge and teeth system.
🔹 Common Materials:
High-strength wear-resistant steels (e.g., Hardox 450/500).
Surface hardening and wear protection may be applied.
🔹 Terminology:
Bucket Front – general term.
Bucket Face – often used when emphasizing the working surface.
In detailed design, this may include the tooth mounting area.
2. Bucket Bottom (or Bucket Floor)
🔹 Function:
The bucket bottom carries the bulk of the material during operation and withstands static and dynamic loads. It is one of the most heavily worn surfaces due to constant material flow and impact.
🔹 Structural Features:
Flat or slightly curved inner surface.
Often includes reinforcing ribs and wear strips.
Welded to the side plates and cutting edge.
🔹 Common Materials:
High-wear-resistant steel plates (e.g., NM500, Hardox).
May include bolt-on or welded wear plates.
🔹 Terminology:
Bucket Floor – more technical term for drawings.
Bucket Bottom – common in field use.
Related components: wear plates, wear bars, liner plates.
3. Integral Cast Lip
🔹 Function:
The Integral Cast Lip is the primary cutting component of the bucket. It breaks into hard soil, rock, or ore and supports the attachment of bucket teeth.
🔹 Structural Features:
Straight or V-shaped edge fitted with tooth adapters.
Can be a weld-on or bolt-on replaceable component.
Often designed with segments and lip shrouds for modular maintenance.
🔹 Common Materials:
High manganese or alloy steel castings.
Designed for toughness and resistance to fracture.
🔹 Terminology:
Cutting Edge – refers to the actual cutting blade.
Lip – broader term that includes the whole front lower structure holding the teeth.
Related parts: tooth adapters, teeth, lip shrouds, segments.
4. Hinge Neck
🔹 Function:
The hinge connects the bucket to the excavator or loader arm. It allows rotational movement for digging, tilting, and dumping actions.
🔹 Structural Features:
Includes ear plates with precision-aligned holes.
Centralized around the hinge pin (or pivot pin).
High-load bearing area that must maintain tight clearances.
🔹 Common Materials:
Alloy steels for hinge pins and bushings.
Hardened surfaces and lubricated joints to reduce wear.
🔹 Terminology:
Hinge – refers to the complete joint system.
Hinge Pin – the pivot shaft enabling movement.
Pivot Point – the axis of rotation.
Additional terms: ear plates, bushings, pin bosses.
三.Key Inspection Points for Electric Shovel Bucket
1.Check for any interference between the hinges and the bore surfaces.
2.Verify the fit between the heel plate and the base plate.
3.Inspect for potential interference between the wear packages on the front and rear plates.
4.Slowly cycle the bucket open and closed through its full range of motion multiple times to check for any abnormal noises or interference.
5.Slowly move the entire bucket while mounted on the machine stick to ensure that the bottom plate of the bucket properly contacts the designated stop position on the stick.
6.If the mechanical stops do not make simultaneous contact on both sides of the bucket and stick, the stops on either the bucket or the stick must be modified to achieve dual-side contact.
7.After the bucket front is installed onto the base plate:
8.Loosen and remove the transport brackets.
9.Remove the lifting lugs from the front of the bucket.
10.Follow the appropriate preheating procedure, and once welding is completed, grind the weld seams to a smooth finish.
