Overview

EN 16228-2:2014+A1:2021 is the CEN European safety standard for mobile drill rigs used in civil and geotechnical engineering, quarrying and mining. Published with Amendment 1 (2021), it is a Type C standard (per EN ISO 12100) that supplements the common requirements in EN 16228‑1. The standard addresses significant hazards associated with mobile drill rigs that operate in soil or soil-and-rock mixtures throughout the machine’s life when used as intended or under reasonably foreseeable misuse.

Key topics and requirements

This part adds or replaces requirements from Part 1 and focuses on hazards and protective measures specific to mobile drill rigs. Major technical topics include:

• Hazard identification for mobile drill rigs used above ground and underground (ground investigation, anchoring, mini‑piling, geothermal, water wells, landfill drilling, underpinning and tunnelling).
• Stability and strength requirements, including tipping angle and operational stability checks.
• Braking systems: service, secondary and parking brake provisions and verification procedures (wheel‑mounted and skid‑steer rigs).
• Guards and sensitive protective devices to prevent access to moving parts; requirements for rod/auger guides and protection against rotating and percussive elements.
• Winches, ropes and draw-works safety for movement on slopes.
• Operating positions and controls ergonomics for safe operation.
• Fire protection, noise (noise test code in Annex A) and special protective modes.
• Functional verification and testing requirements, including brake test procedures (Annex B) and information for use (operator documentation, special conditions for underground or suspended rigs).
• Scope exclusions: oil & gas rigs, tunnelling TBMs and certain mining and handheld machines (e.g., EN 12348 core drills, ISO 11148‑5 hand-held devices).

Applications and who should use it

This standard is intended for manufacturers, safety engineers, machine designers, testing and conformity bodies, procurement teams, site managers and maintenance personnel involved with:

• Mobile drill rig design, manufacture and modification
• Safety compliance and CE marking where applicable (supports essential health & safety requirements of EU machinery directives)
• Risk assessments, commissioning and periodic testing on construction, geotechnical, geothermal and water‑well projects
• Contractors and owners specifying safe equipment for civil engineering, geotechnical investigations, quarrying and mining site operations will rely on this standard to ensure consistent safety practices.

1 Scope
This European Standard, together with part 1, deals with all significant hazards for mobile drill rigs for
!in soil or soil and rock mixture in" civil and geotechnical engineering, !deleted text" 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 (see Clause 4).
The requirements of this part are complementary to the common requirements formulated in
!EN 16228-1:2014+A1:2021".
This document does not repeat the requirements from !EN 16228-1:2014+A1:2021", but adds or
replaces the requirements for application for mobile drill rigs.
In this document the general term “mobile drill rig” covers several different types of machines for use
in:
— civil engineering;
— geotechnical engineering (including ground investigation, anchoring, soil nailing, mini-piling,
ground stabilization, grouting);
— water well drilling;
— geothermal installations;
— landfill drilling;
— !underpinning and tunnelling";
— for use above ground as well as underground.
Typically, the process of drilling involves the addition of drill rods, tubes, casings or augers etc.,
normally threaded, as the borehole extends to depth.
NOTE 1 !EN 16228–4:2014+A1:2021 covers machines with a rotary torque greater than 35 kNm."
NOTE 2 The term “drill rigs” includes rigs with a separate power pack supplied by the rig manufacturer.

rock according to prEN 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 CEN/TC 196);
— 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 CEN/TC 196);
— core drilling machines on stand covered by EN 12348;

5 Safety requirements and/or protective measures
5.1 General
Drill rigs shall comply with the requirements of !EN 16228-1:2014+A1:2021", as far as not
modified or replaced by the requirements of this part.
5.2 Boom mounted working platforms for underground use
!EN 16228-1:2014+A1:2021, 5.13.2" does not apply.
When a drill rig for underground use is equipped with a boom mounted working platform intended for
use in an area where there is risk of object fall, the person(s) on the platform shall have adequate
protection. A suitably designed protective structure, FOPS shall be provided over the platform.
Level I of EN ISO 3449:2008 shall be the minimum requirement (e.g. underground pre-armouring
machines). Level II shall be chosen where there is the risk of rock fall.
NOTE The FOPS !can" be adjustable taking into account the various functions to be performed from the
platform.
Drill rigs equipped with one or more boom mounted platforms shall comply with
!EN 280:2013+A1:2021".
!Pre-armouring machines" are exempted from the following requirements of
!EN 280:2013+A1:2021":
— a device that prevents driving of the vehicle when the boom mounted platform is not in its
transport position;
— a device that prevents movement of the platform while the stabilizers are not set;
— a device that prevents adjustment of the stabilizers while the boom mounted platform is not in its
transport position;
— a device, located in the operators compartment, that indicates that the boom mounted platform is
not in its transport position;
— a load sensing system;
— an adjustment for uneven ground for base plates on stabilizing jacks.
NOTE The exceptions are justified for the following reasons:
— the primary function of the stabilizers is for use during drilling;
— the need to maneuver in narrow tunnels;
— risk of rock fall;
— size and weight of machine.
!Pre-armouring machines" are exempted from the requirements of !EN 280:2013+A1:2021",
5.7.4. The boom mounted working platform shall be operated from both the platform and the operator's
station. Only one control position shall be active at a time except for stop controls and emergency stop.
In case of emergency, e.g. rock fall, it shall be possible to override the controls of the platform by the
control at the operator’s station.
Overturning of !pre-armouring machines", due to overload of the platform, of a drill rig for
underground use and equipped with a boom mounted working platform is not considered a significant
hazard due to the size and weight of the rig. However overload of the boom and platform shall be
prevented by restricting the platform size according to !EN 280:2013+A1:2021", 5.4.1.6, or by
mechanical, hydraulic or electronic protection systems. The platform shall be subject to a static load test
according to !EN 280:2013+A1:2021", 6.1.4.3.
Any overload prevention system fitted shall not prevent the platform being lowered.
5.3 Requirements for strength and stability
5.3.1 Stability calculation - Tipping angle
!EN 16228-1:2014+A1:2021, 5.2.3.5" applies with the following modification(s).
The stability angles α shall not be less than 10° in any directions when tramming and be not less than 5°
under any other conditions.
For rubber-tyred drill rigs for underground use, the stability angle of 10° includes also a margin for the
effects of the dynamic forces from acceleration and braking of the total drill rig.
5.3.2 Operating conditions
5.3.2.1 General
!EN 16228-1:2014+A1:2021, 5.2.3.6" applies with the following additions.
The stability of the drill rig shall be calculated for the operating conditions as described in
subclauses 5.3.2.2, 5.3.2.3 and 5.3.2.4, which shall be stated in the operator's manual.
5.3.2.2 In service – during operation
The calculation shall be carried out for the most unfavourable combination of conditions that may occur
with the following additional examples:
— booms, service platforms and feed extension in advanced positions and turned to the limit of the
working area. The rated load shall be applied to the service platform;
— steering turned in the extreme and most unfavourable position (articulated carrier);
— mast at the utmost front upward position and maximum forward mast inclination;
— attachments at their highest position;
— maximum pulling force on the rope suspended tool in the bore hole.
5.3.2.3 Tramming
Stability in tramming shall be calculated for the conditions specified in the operator's manual, taking
into account the most unfavourable case.
5.3.2.4 Travelling and operating on slopes
The stability calculations shall be done for the most unfavourable combinations of gradient and load
condition as specified in the operator's manual.
5.4 Fire protection
!EN 16228-1:2014+A1:2021, 5.26" applies with the following additions.
For the fire protection of mobile drill rigs intended for use underground, there shall be a fixed on-board,
fire extinguishing system covering the diesel engine compartment and battery installation, e.g. unfused
cables. For remotely controlled, unmanned or partly manned mobile drill rigs, the triggering system
shall be automatic.
On remotely controlled mobile drill rigs it shall be possible to trigger the fire extinguishing system from
the control panel and/or (if applicable) from the monitoring position.
