Carrier-Class Sizing Ladder Calculator

Enter your machine’s operating weight and the material you dig. The tool maps your ton class to a recommended bucket width range, an SAE J296 heaped capacity range, and the effective load you can expect per pass after the material fill factor.

2 · Recommended Bucket

Midi Excavator 8–14 t class
Bucket width range 24–48inches
SAE J296 heaped capacity 0.20–0.50cubic yards (yd³)

effective load per pass = rated capacity × fill factor (100%)

0.20–0.50 yd³ per pass

Fill factor for Moist loam: 100–110%. Loose, free-flowing material heaps above the strike-off plane, so a pass can carry slightly more than rated.

Capacity rated per SAE J296 (1:1 heaped at the material’s angle of repose). Width and capacity ranges are class guidance, not a single fixed size.

Reality Check

Bigger is not always more productive. A wider bucket spreads the same hydraulic force across more teeth, which lowers breakout force per inch of cutting edge. In dense clay, bank material, or rock, an over-sized bucket stalls, fills partially, and slows cycle times — a narrower, properly matched bucket digs full passes faster.

Estimates are class-level guidance. Final fitment and exact bucket spec are confirmed by [COMPANY NAME] before order, against your machine model, pin/linkage geometry, and duty cycle.

Payment protected by staged delivery proof
Pay the balance after machine proof, not on blind trust.

Used excavator buyers need more than a product photo. Liehuang uses a staged payment workflow: deposit to reserve the machine, inspection evidence before balance, and export documents plus shipment tracking before release.
