EN 14238

The European standard for manually controlled load manipulating devices. It sets the safety requirements for equipment where the operator guides the load while the device carries it – covering actuating forces, load-holding devices, behaviour on loss of power and marking. It is the reference against which the design of a manipulator has to be measured.

01

What the standard applies to

EN 14238 is titled “Cranes – Manually controlled load manipulating devices”. It is the European product standard for devices where a person guides the load directly by hand while the device carries or balances the weight. The operator stands within the range of movement of the load – that distinguishes the manipulator from a crane with a pendant and from a robot behind a guard fence, and it shapes the safety requirements.

02

Its place among the standards

Machinery safety standards are organised on three levels. Type A standards such as EN ISO 12100 define basic concepts and the method of risk assessment. Type B standards deal with individual safety aspects or safeguards, for example EN ISO 13849-1 on safety-related control systems. Type C standards cover a particular kind of machine – EN 14238 is one of them.

Where a type C standard regulates a requirement specifically, it takes precedence over the more general standards. Harmonised standards give a presumption that the requirements of EU machinery law they cover are met; the edition listed in the Official Journal of the EU is the one that counts.

03

The topics it deals with

Like every product standard it follows a fixed structure: list of significant hazards, safety requirements and protective measures, verification, information for use. In substance it addresses what characterises a manually guided manipulator.

  • Actuating and guiding forces the operator has to apply.
  • Holding the load and behaviour on failure of the energy supply.
  • Protection against unintended release of the load.
  • Movements of the device when the load is picked up or released.
  • Marking, operating instructions and tests.
04

Neighbouring standards

The standard does not cover everything hanging at a workstation. Non-fixed load lifting attachments come under EN 13155, power-driven hoists under EN 14492-2, industrial robots under EN ISO 10218. A permanently fitted gripper, by contrast, is part of the machine and is assessed with it.

05

What the standard does not replace

A product standard describes the typical manipulator. The risk assessment for the actual device remains the manufacturer’s task – above all for everything the standard cannot know: the gripper, the part, the sequence, the environment. And it addresses the manufacturer. The operator’s duties – risk assessment, instruction, periodic inspection – follow from national law; in Germany from the Industrial Safety Ordinance, in the United Kingdom from PUWER and LOLER.

Frequently asked questions

Frequently asked questions about EN 14238

Is applying EN 14238 mandatory?

No. Standards are voluntary; the requirements of EU machinery law are binding. Applying a harmonised standard, however, gives the presumption of conformity. Anyone who deviates has to demonstrate that their solution achieves the same level of safety.

Does the standard also apply to the gripper?

A permanently fitted gripper is part of the manipulator and is covered by its risk assessment. A lifting attachment placed on the market separately and hung on the device comes under EN 13155.

How does a manipulator differ from a robot in terms of standards?

A manually controlled manipulator follows the operator’s hand at every moment and executes no programmed sequence. An industrial robot moves under program control and comes under EN ISO 10218, with entirely different protective concepts.
