MTW Launches LA6256LA CHA Cast Cutting Edge: 200 kg Heavy-Duty Wear Part for Earthmoving Equipment
November 2, 2026
Built for the Ground That Eats Steel
Every cutting edge has one job: hold its shape long enough to keep the machine earning. In dozing, loading and material handling, the edge takes the punishment that would otherwise reach the bucket, the moldboard and the structural welds behind them. The LA6256LA cast cutting edge from MTW is a heavy-duty cast wear part engineered for exactly that duty cycle, with a unit weight of 200 kg and a casting pattern code of CHA.
This article covers what the LA6256LA is, where it fits, and how to specify it correctly so the part you receive matches the part your machine expects.
MTW has released the LA6256LA cast cutting edge, a 200 kg heavy-duty cast steel wear part for earthmoving and material handling equipment. The part is identified by OEM part number LA6256LA, casting pattern code CHA and quotation code DTD7, giving buyers, engineers and aftermarket suppliers a single, unambiguous reference for ordering and cross-checking.
Cutting edges sit at the front line of wear. They take the abrasion and impact that would otherwise be transferred to the bucket, the moldboard and the structural welds behind them. With a substantial unit weight and a heavy-duty cast body, the LA6256LA is aimed at operators working hard rock, slag, overburden and recycled material, where a thin rolled edge would be consumed ahead of schedule.
Why Cast, Not Rolled
Cast cutting edges are chosen where abrasion is severe and section thickness matters. Casting allows the manufacturer to place material precisely where wear occurs, and to build a profile that a rolled plate cannot reproduce economically. For fleet operators working hard rock, slag, overburden and recycled material, that translates into longer wear life between change-outs and less unplanned downtime.
The LA6256LA follows this philosophy: a robust cast body, a substantial unit weight, and a clean identification system so replacement sourcing does not turn into guesswork.

Key Features at a Glance
- Heavy-duty cast design — built for abrasive, high-impact wear-part applications.
- 200 kg unit weight — substantial mass and section thickness for demanding duty cycles.
- Triple identification — OEM part number LA6256LA, casting pattern code CHA and quotation code DTD7 all appear on the record, so buyers, engineers and suppliers refer to the same part.
- Replacement-ready — designed as a direct wear-part replacement for compatible equipment.
- Color options — standard red or customer-designed finish for fleet coding and brand consistency.
Where the LA6256LA Fits
The LA6256LA is intended for compatible earthmoving equipment that requires heavy-duty cast wear components. Typical application areas include:
- Earthmoving and bulk dozing operations
- Material handling in quarries, yards and processing plants
- Cutting-edge replacement and scheduled wear-part maintenance
- Heavy-duty wear-part programmes in mining and construction fleets
Because cutting edges are machine-specific, dimensions, hole spacing and mounting geometry must be confirmed against the equipment before ordering. Sending us the machine model and the existing part number is the fastest way to lock this down.
How to Order Without Guesswork
- Send the part reference. Quote LA6256LA, or the casting pattern code CHA, or the quotation code DTD7.
- Confirm the machine. Provide equipment model, bucket or blade type, and any photos of the worn part in place.
- Confirm the quantity. Minimum order quantity is 5,000 kg; mixed orders across cutting edges, end bits and bucket protection can be discussed.
- Plan the lead time. Standard delivery is 6–8 weeks, palletised in plywood for export.
FAQ
What is the LA6256LA?
The LA6256LA is a heavy-duty cast steel cutting edge, a wear part for compatible earthmoving equipment, with a unit weight of 200 kg.
