HELI-Custom Forklift Spare Parts Assembly 2ton 3ton 5ton Double Thriplex Manufacture Forklift Mast

Forklift Mast Assembly — Duplex/Triplex, 2T to 5T

The forklift mast assembly is the complete vertical lifting structure — the welded steel channel frame that houses the lift cylinders, mast chains, roller bearings, carriage, and fork mounting — available in duplex (two-stage) and triplex (three-stage) configurations for 2-ton, 3-ton, and 5-ton forklift capacity classes. A duplex mast assembly provides two stages of lift (outer channel + inner channel with free-lift cylinder), while a triplex mast assembly adds a third intermediate channel for greater maximum lift height without increasing the collapsed mast height — essential for forklifts operating in low-doorway warehouses or shipping containers where the lowered mast must clear the door header. A cracked channel weld, worn roller bearing tracks, or bent channel on a forklift mast assembly affects lifting smoothness, load stability at height, and in severe cases, the structural integrity of the entire lifting system.

Fabricated from heavy-gauge formed steel channels with precision-welded cross-members, integrated cylinder mounts, chain anchor points, and roller bearing tracks, this forklift mast assembly is built to HELI OEM mast specifications for 2T, 3T, and 5T capacity classes.
