Terminology and classification of electrical control systems for industrial vehicles

1 Scope

China's national terminology and classification for the electrical control systems of industrial trucks. A forklift's control system has changed completely in two decades: the contactor-and-resistor arrangement that switched a series motor between fixed speeds has been replaced by an electronic controller driving an AC induction or permanent magnet motor, with regenerative braking, programmable performance curves, and integration with the truck's stability and telemetry functions. That change brought a vocabulary that was not settled, and it brought a classification problem that matters practically: control systems now differ in ways that determine what a truck can do and what it costs to maintain, and a buyer comparing two machines needs the categories to mean the same thing. Fixing the terms is also a safety precondition, since the control system now performs functions - speed limiting, load-dependent behaviour - on which the truck's stability depends.

This document defines the terminology and classification of electrical control systems for industrial vehicles. This document applies to the electrical control systems of various types of industrial vehicles defined in GB/T 6104.1.
