Overview

prEN ISO 20770-1 (ISO/DIS 20770-1:2025) is a draft CEN/ISO safety standard establishing common safety requirements for drilling and foundation equipment. It covers machines used in earthworks, foundation construction and underground works (ICS 53.100; 93.020). The document sets out general safety principles and risk-reduction measures that apply across a broad range of drilling rigs, piling machines, leaders/derricks, winches and related carrier systems. Note: this is a draft circulated for comment and subject to change.

Key topics and technical requirements

The standard’s table of contents shows the scope of technical coverage. Major topics include:

• General safety requirements and risk reduction measures - overarching obligations for design and guarding.
• Strength and stability - loads, structural calculations, rigid-body stability and special provisions for floating platforms (ship, barge, pontoon).
• Electrotechnical systems - battery installations, electromagnetic compatibility (EMC) and general electrical safety.
• Hydraulic and pneumatic systems - safe design of pressurized systems, hoses, pipes and fittings.
• Power-supply failure and uncontrolled motion - requirements to limit hazards from loss of power.
• Braking and winch systems - travelling and slewing brakes, winches, ropes, drums and chain requirements.
• Leaders, derricks and feed systems - structural and stroke-limiting provisions.
• Inclination indicators and limiting devices - for leader/boom and carrier stability monitoring.
• Ergonomics and operating positions - control-station layout, visibility and service access.
• Control systems and safety performance - performance levels for safety-related control functions, emergency stop, start/stop behaviour, remote/automated operation.
• Handling, lifting, towing and transport - retrieval, tie-down, lifting points and locking of articulations.
• Protection against moving parts, hot/cold surfaces, sharp edges - guards and protective measures for drilling tools, transmission components and rod connections.
• Personnel platforms and fall/ejection protection - requirements for platforms used for lifting personnel and protection from falling objects.

Applications and practical value

This standard is intended to be used for:

• Designing and manufacturing safer drilling rigs and foundation machines.
• Developing procurement specifications and acceptance criteria for equipment used in foundation construction, piling and underground works.
• Performing machine risk assessments and preparing operating/maintenance instructions.
• Guiding site safety managers, OEMs, certification bodies and conformity assessment procedures.
• Informing training programs for operators, service technicians and safety officers.

Who should use this standard

• Machine manufacturers and OEM design teams
• Safety and compliance engineers

Drilling and foundation equipment — Safety —
Part 1:
Common requirements
1 Scope
This document specifies the common safety requirements for drilling and foundation equipment.
This document deals with the significant hazards (see Annex F) common to drilling and foundation
1)
equipment (see ISO 11886:____) , , when they are used as intended and under the conditions of misuse
which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine
(transport, assembly, dismantling, equipment in service and out of service, maintenance, moving on site,
storage, disabling and scrapping).
NOTE 1 The requirements specified in this part of the standard are common to two or more families of drilling and
foundation equipment.
This document gives common safety requirements for drilling and foundation equipment and is intended
to be used in conjunction with relevant parts of this series (Part 2 thru Part 6). These machine specific
parts do not repeat the requirements from part 1 but supplement or modify the requirements for the type of
drilling and foundation equipment in question.
For multipurpose machinery, the parts of the standard that cover the specific functions and applications are
used, e.g. a drilling machine also used as a piling machine will use the relevant requirements of ISO 20770-1 to -6.
The following machines are excluded from the scope of this standard:
— autonomous or semi-autonomous (as defined in ISO 17757:2019) drilling and foundation equipment;
— tunnelling machines, unshielded tunnel boring machines and rodless shaft boring machines for rock
according to EN 16191;
— raise boring machines;
— drill rigs used in oil and gas industry ;
— specialized mining machinery and equipment for opencast mining (e.g. rock drill rigs, blast hole drills)
(under the scope of ISO/TC 82);
— all underground mining machinery and equipment for the extraction of solid mineral substances (e.g.
rock drill rigs, raise boring machines, shaft boring machines, mining auger boring machines, jumbos) as
well as machinery and equipment for underground mine development (under the scope of ISO/TC 82);
— core drilling machines on stand (covered by EN 12348);
— hand-held machines (in particular machines covered by ISO 11148-5);
— horizontal directional drilling machines (HDD) as defined in ISO 21467).
NOTE 2 ISO 23224 (in preparation) deals with the significant hazards for horizontal directional drilling (HDD)
machines.
NOTE 3 Specific requirements for offshore applications are not covered by this document.
