Technical details and manufacturing context for Carriage Beam

Definition
The carriage beam is the primary horizontal structural component of a fork positioner's carriage assembly. It provides the rigid mounting platform and linear guidance for the forks, ensuring stable and precise movement during load positioning operations. As part of the fork positioner, it directly interfaces with the mast or vertical lift mechanism and supports the entire load-bearing structure of the moving forks.
Working Principle
The carriage beam is fixed to the carriage assembly of the fork positioner. It translates vertically along the mast rails via chains or hydraulic cylinders. Its rigid construction prevents deflection under load, maintaining fork alignment. Linear bearings or rollers attached to the beam interface with mast channels to provide smooth, guided vertical travel for precise fork positioning.
Common Materials
High-strength steel, Alloy steel
Technical Parameters
  • Overall length of the beam, determining the maximum fork spread and load center capacity. (mm) Standard Spec
Components / BOM
  • Mounting Plates Part
    Provide reinforced attachment points for connecting the beam to the carriage frame and fork mechanisms.
    Material: Steel
  • Bearing Rails
    Precision-machined surfaces or attached rails that interface with mast rollers or bearings for smooth vertical travel.
    Material: Hardened steel
  • Reinforcement Ribs Part
