Inner mast channel Component – Machinery and Equipment Manufacturing

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.

Technical Parameters

Depth 40-100 mm
Width 80-200 mm
Length Customized to mast height (typically 2-12 meters)
Load Capacity 500-5000 kg per channel
Surface Finish Ra 1.6-3.2 μm
Wall Thickness 4-10 mm
Straightness Tolerance ≤1 mm per meter

Standards

ISO 6055, DIN 15185
