Foundry machinery sand removal and core removal equipment Safety Technical Specifications

1 Scope

GB/T 47237-2026 is the Chinese national standard covering the shakeout - where hot castings and sand are separated by violent vibration, producing dust, noise and hot metal in one place, and where the guarding has to work with material constantly passing through it. It is one of seven foundry machinery safety standards published together on 27 February 2026, which between them cover a whole foundry: melting, moulding and coremaking, pouring, shakeout, blasting, sand plant and die casting. First edition, in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the safety requirements and/or risk reduction measures for core removal equipment, as well as usage information, and describes the corresponding verification methods. This document outlines the procedures for using the core removal equipment for its intended purpose and for use under conditions of misuse that the manufacturer could reasonably foresee. Examples of major hazards, hazardous conditions, or hazardous events related to this type of equipment (see Appendix A). This document applies to the design, manufacture, and acceptance of core removal equipment.

Note. Sand removal and core removal equipment includes sand removal machines, sand removal drums, related sand removal equipment (vibrating conveyors, flat/scaled conveyors, foundry robots), core removal machines, and core removal... Core-related equipment (loading and unloading robots). This document does not apply to workpiece lifting and transfer equipment, or ventilation and dust removal equipment.
