Size a weld-on edge for a telehandler by matching three dimensions to the carrier: the cutting edge width to the bucket or blade width, the edge thickness and section to the machine’s operating weight and breakout force, and the weld prep to the parent plate thickness. Undersizing wears through in weeks; oversizing adds weight where the boom and tilt circuit do not want it.
Start from the carrier, not the edge
A telehandler is a load-handling machine first and a snow tool second. Its boom, tilt geometry and hydraulic capacity set hard limits on what a weld-on edge can weigh and how aggressively it can be shaped. Before opening any catalogue, collect the carrier data below and treat it as the design envelope rather than a wish list.
- Rated capacity at the relevant reach and the machine’s own operating weight.
- Bucket or blade width at the weld line, measured — not taken from a spec sheet.
- Parent plate thickness at the weld location, and its material grade if known.
- Hydraulic tilt and auxiliary circuit pressure and flow.
- Tyre type and machine class, since these set traction and therefore the load the edge can see.
Two machines of similar weight can have very different bucket geometry, so the weld line measurement is the one that decides the order. A distributor who quotes from the machine model alone will eventually ship an edge that fits nothing.
Width, thickness and section
Width is the straightforward dimension: the edge should cover the full weld line, or stop a defined distance short of each side where the bucket has corner gussets. Thickness and section are where sizing actually happens, because they control stiffness, wear allowance and weight.
| Parameter | What it depends on | Practical range |
|---|---|---|
| Edge width | Measured weld line, corner geometry | Matches bucket width; shortfall depends on gusset design |
| Plate thickness | Machine class, breakout force, expected duty | Thin for light utility work to heavy section for high-duty fleets |
| Section profile | Penetration vs. stiffness trade-off | Flat, bevel or stepped, depending on surface and load |
| Wear allowance | Hours per season, abrasive content of surface | Consumable allowance varies widely; depends on site |
| Weight per edge | Thickness × width × section | Must stay inside boom capacity margin |
Weight is the constraint buyers underestimate. A heavier section improves wear life but consumes rated capacity and adds tilt load, so the correct choice is usually the lightest section that meets the expected duty cycle.
Weld prep and fit-up
A weld-on edge is a structural joint, not a bolt-on accessory. The bevel, root gap and parent plate condition determine whether the edge survives the first season or cracks at the toe. Specify the prep explicitly on the drawing and confirm it at goods-in.
- Confirm parent plate thickness and grade at the weld line; thin plate needs a smaller leg and possibly a backing detail.
- Specify bevel angle and root face on the purchase drawing, not verbally.
- Check that the edge sits flat along the weld line with no forced gap.
- Clean the parent plate to bare metal before fit-up; paint and scale drive porosity.
- Sequence welds to balance heat and limit distortion across the width.
- Inspect the toe after cooling; that is where fatigue starts.
Dimensions and hole spacing follow the product page specification. Where a drawing and a catalogue disagree, the drawing governs and the discrepancy should be raised before the batch is cut.
Wear life and replacement planning
Wear life is a range, not a number. It depends on hours, surface abrasiveness, down-pressure and how much material the operator is willing to lose before changing the edge. Fleet buyers should plan replacement on a measured wear allowance rather than a calendar, and keep the measurement simple enough that operators actually do it.
For context on how weld-on edges are specified and supplied, see the weld-on cutting edges range and the telehandler cutting edge product page. Both are starting points for dimensioning, not substitutes for the carrier measurements above.
The commercial side: specification risk
For a distributor or fleet buyer, the expensive failure is rarely the edge itself — it is the batch that arrives with the wrong bevel, the wrong weld-line width, or a section that pushes the machine outside its capacity margin. That risk is priced in rework, downtime and return freight, and it scales with order size.
MOQ and lead time depend on section, thickness and whether the profile is standard or cut to drawing; custom sections typically carry a higher minimum and a longer schedule than stock profiles. Total cost should be assessed per operating hour, not per piece: a slightly more expensive heavier-duty edge that lasts longer can be cheaper than two light replacements, but only if the weight stays inside the boom limit. Where public procurement is involved, the specification wording itself becomes a commercial risk — see this note on reading public bid tabulations for cutting edges for how line items are typically compared.
Quick summary
Size a weld-on telehandler edge from the carrier’s measured weld line, parent plate thickness and capacity margin, then choose the lightest section that meets the expected duty. Width, thickness, profile and weld prep should all be fixed on a drawing before the batch is cut. Wear life and cost are ranges that depend on site conditions and duty cycle.

This page is a sizing guide, not an engineering approval. It does not cover weld procedure qualification, structural certification, or machine-specific load charts, and it does not replace the carrier manufacturer’s attachment guidance. Dimensions and hole spacing follow the product page specification; confirm all figures against the drawing before ordering.
