The machinery concerned and the extent to which hazards, hazardous situation and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those, which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. SIST EN 16228-2:2014



EN 16228-2:2014 (E) 6 1 Scope This European Standard, together with part 1, deals with all significant hazards for mobile drill rigs for civil and geotechnical engineering, quarrying and mining 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. This document does not repeat the requirements from EN 16228-1, 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, tunnelling, mining and quarrying; — 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 For machines with torque greater than 35 kNm see EN 16228–4 initially. NOTE 2 The term “drill rigs” includes rigs with a separate power pack supplied by the rig manufacturer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

2.1 Fire 5.4 4 Hazards generated by noise, resulting in:
4.1 Hearing losses and physiological disorders Annex A 4.2 Accidents due to interference with speech communication and warning signals Annex A 5 Safety requirements and/or protective measures 5.1 General Drill rigs shall comply with the requirements of EN 16228-1:2014, as far as not modified or replaced by the requirements of this part. 5.2 Boom mounted working platforms for underground use Subclause 5.13.2 of EN 16228-1:2014 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 may 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. SIST EN 16228-2:2014



EN 16228-2:2014 (E) 10 Drill jumbos and pre-armouring machines are exempted from the following requirements of EN 280:2013: — 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. Drill jumbos and pre-armouring machines are exempted from the requirements of EN 280:2013, 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 drill jumbos and 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, 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, 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 Subclause 5.2.3.5 of EN 16228-1:2014 applies with the following modification(s). The stability angles . 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 Subclause 5.2.3.6 of EN 16228-1:2014 applies with the following additions. SIST EN 16228-2:2014



EN 16228-2:2014 (E) 11 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 Subclause 5.26 of EN 16228-1:2014 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. 5.5 Guards Subclause 5.23.2.2.2 of EN 16228-1:2014 applies with the following additions. For drilling machines that do not have significant hazards caused by feed movement of the rotary head, (e.g. rotary head is higher than 1 600 mm from ground level), the guarding of the moving parts involved in the working process may be restricted to the guarding of the rotating parts, to prevent the operator inadvertently coming in contact with moving parts when working in close proximity to the drill string. When drill rigs are equipped with guards, these guards shall comply with the following: — maximum height of the bottom edge of the guard shall be up to 500 mm from ground level or not more than 200 mm above the upper clamps/jaws; — the upper level of the guard shall prevent unintentional access to the moving parts up to 1 600 mm from ground level and/or such height above ground level where persons have operational access. SIST EN 16228-2:2014



EN 16228-2:2014 (E) 12 The design of the guard shall ensure a sufficient visibility of the working area. 5.6 Protection against moving parts on specific machine types 5.6.1 General All drill rigs shall comply with subclause 5.23 of EN 16228-1:2014 with the following exceptions only: — underground pre-armouring machine (see 5.6.2); — drill jumbo (see 5.6.3). 5.6.2 Underground pre-armouring machine Subclause 5.23.2 of EN 16228-1:2014 does not apply, except 5.23.2.2.4. The installation of the drill string prior to operation is regarded as a rigging operation to be done with the use of external means such as cranes. For the rigging operation the restricted operating mode is used as in subclause 5.23.2.2.4 of EN 16228-1:2014. If there is a need of addition and removal of rod during the drilling process it shall be done by a mechanized rod handling device fitted on the machine. Machines with a boom mounted platform shall be fitted with a mode selector or an interlocking function to allow platform operations only when movements of rotation and feed and motions for positioning the drill string are prevented. The machine shall be fitted with a remote control system with all controls of hold to run type except feed and rotation. NOTE The use of the remote control removes the operator from the danger zone and gives sufficient visibility of the working process. The sensitive protective devices as in 5.23.2.2.3 of EN 16228-1:2014 should be fitted if the work environment allows it to be done without creating additional hazards due to their malfunction. 5.6.3 Drill jumbo 5.6.3.1 General Subclause 5.23.2 of EN 16228-1:2014 does not apply, except 5.23.2.2.4. The drill jumbo shall be so designed, constructed and equipped that manual operation in the danger zone is minimized. 5.6.3.2 Restricted access to the rotating parts danger zone Drill jumbos shall have motion detectors to detect access of persons to the danger zone formed by rotating parts. According to operational mode, choice and application of these detectors are defined in 5.6.3.3, 5.6.3.4 and 5.6.3.5. NOTE There might be other technical solutions than motion detectors that can achieve the same or higher level of protection. This in combination with the rock walls does limit access to the danger zone. The area beyond the technical limits of the motion detector should be job site controlled. SIST
