Quick cheat sheet
- Prefix shows the product family (SY = excavator, STH = telehandler, ST = skid steer).
- Numbers approximate the size or class (16 ≈ 1.6 metric ton, 35 ≈ 3.5 metric ton, 335 ≈ 33-35 metric ton, 750 ≈ 75 metric ton).
- Suffix letters indicate configuration or trim (LC = long carriage, U/C/H = series variants, PRO = pro or new-gen).
What the prefixes usually mean
- SY typically means excavator. If you’re looking at digging, trenching, grading, or anything with a stick and boom, you’re probably looking at SY.
- STH usually means telehandler. Think reach, placing pallets or material at height, and rough-terrain lifting.
- ST and similar codes often mark compact loaders or skid steers.
- SL, SSR, SW, SMG, or other letter codes appear on backhoes, wheel loaders, compactors, motor graders, or specialty lines.
What the numbers tell you
- Two-digit numbers on small machines generally reflect approximate metric tonnage. For instance, 16 points to roughly 1.6 ton class, 35 to about 3.5 ton.
- Three-digit numbers indicate larger classes and higher operating weights. Models like 215, 335, or 385 are medium-to-large machines.
- Very large numbers, such as 500 or 750, are heavy machines for large earthmoving tasks.
Suffixes and what they mean
| Suffix | Usual meaning |
|---|---|
| LC | Long carriage or long undercarriage for more stability and better load distribution |
| U | Series/configuration identifier commonly used on U.S. market minis |
| C | Conventional series or standard configuration for certain markets |
| H | Heavy or high-power configuration |
| PRO or new-gen | Newer generation or pro trim with updated features |

Common mistakes and what to double-check
- Don’t assume the number equals the exact weight. It’s a guide to size, not a replacement for the spec sheet.
- Suffixes change hydraulic flow, undercarriage length, and cab options; confirm what a suffix actually does for that model.
- OEM naming evolves. A letter that meant one thing three years ago could be repurposed on a new generation. When a spec matters, verify with your dealer and the latest PDF.
