Buyer question

We replace whole cutting edges even when only one end is worn. Would segmented edges lower our replacement cost, or do the joints and extra bolts cause new problems?

Short answer
Segmented edges help when wear is uneven or damage is local, and when handling a long edge is difficult. Full-length edges can be simpler to fit and align. The comparison below is a general framework, with no wear or price data.

Comparison

Factor Segmented Full-length
Handling Pieces are lighter and easier to lift for one person Heavy and awkward; may need two people or a lifting aid
Replacement Replace only the worn or damaged piece Replace the whole edge
Spare stock Spare segments can be held for several trucks Spare full lengths take more space
Alignment Joints between pieces must line up One continuous surface, fewer joints
Hardware More bolts and parts to keep tight Fewer fasteners
Wear at joints Joints can catch or wear if misaligned No joints to wear
Cost Depends on how often only part of the edge is worn Depends on whole-edge life

When segmented tends to help

Segments help when the wear is local, because you replace only what wore.

  • Wear is concentrated at one end or the middle, for example on a one-sided route.
  • The plow is large and a full edge is hard to handle.
  • You want a smaller spare stock covering several truck sizes.

When full-length tends to help

A full-length edge helps when the wear is even, because there is nothing to save.

  • Wear is even across the length.
  • Fitters prefer fewer parts and less alignment work.
  • Joint damage has been a problem on your surfaces.

How to decide

Segments trade purchase price for handling time. The comparison only works if you cost both.

  1. Look at your worn edges: is the wear even or localised? Localised wear favours segments; even wear favours full length.
  2. Count how long a change takes with each type, and how many people it needs. Labour is the hidden half of the comparison.
  3. Ask the supplier for the price of one segment and one full length. Compare cost per metre of usable edge, not per piece.
  4. Trial segmented on one truck and compare cost and downtime over a season. A season is the shortest period that shows the difference.

A simple trial design

Fit segmented edges on one truck and full-length on a similar truck on a similar route. Record fit time, hours of use, replacements and cost. After one season, compare the totals. Keep the trial small and the notes simple, so it actually gets done.

Boundary: No prices, wear figures or product claims are made; use your own wear records and supplier quotes.

↳ Replying to SENTHAI Editorial Team

Start by looking at your worn edges to see where they wear. If wear is local, segments may save cost. If it is even, full length may be simpler. Ask suppliers for the segment price, joint design and bolt pattern, and compare the two options on cost per season, including time and spares, not only unit price.

↳ Replying to Selection perspective

Segmented edges mean more fasteners and more joints to check. Add them to the walk-around, and look for steps between pieces. Keep a record of which segment was replaced, when and why. A tidy log shows whether the saving is real, and where a joint is causing wear or damage.

↳ Replying to Maintenance perspective

Compare the total spare stock cost for each option. A few segments may cover more trucks than several full lengths, but only if the sizes match. Ask for lead times on both and check minimum order quantities. Include handling time and downtime in the comparison, as a cheaper part is not always cheaper to use.
