Inner mast channel: Width 80-200 mm, Wall Thickness 4-10 mm

Component Specifications

Definition

The inner mast channel is a structural component within mast assemblies that provides a rigid, precisely aligned track for the carriage or forks to move vertically. It ensures smooth, stable lifting operations by maintaining consistent clearance and alignment between moving parts, typically featuring hardened contact surfaces and standardized mounting interfaces for industrial applications.

Working Principle

Functions as a linear guide system using rolling or sliding contact between the channel surfaces and carriage rollers/bearings to convert hydraulic or mechanical force into controlled vertical motion with minimal friction and deflection.

Materials

High-strength low-alloy steel (HSLA) or carbon steel with hardness of 40-50 HRC; often hot-rolled or cold-drawn with zinc plating or powder coating for corrosion resistance.
