About this model

A reference-informed reconstruction of a 40 t heavy-duty (container-handler class) forklift, built procedurally in Three.js r186. It is a representative model, not an OEM digital twin.

What is documented

• Class dimensions and layout follow published 40 t data sheets: 40 000 kg at 1 200 mm load centre, about 5.0 m wheelbase, about 4.16 m width over dual front tyres, 18.00-25 tyres, 2 400 × 300 × 135 mm forks, mast lowered about 4.6 m, lift about 6.5 m.
• Reference pages: Hyster H40XM listing, 40 t FD400 data sheet, Kalmar heavy forklift range.

What is inferred

• Body, cab, engine bay, counterweight and hydraulic layout are plausible reconstructions. Service mass (58 t), engine (250 kW), cylinder bore and pump flow are assumptions.
• Telemetry is computed from the model: chain reeving 2:1, lift pressure from rod force and bore, static tip-over margin from moments about the front axle. Not a certified control or stability calculation.
