4 Many years experience earned in quarry & screening industry combined with pipeline contractor requirements

5 Xrok Granite 400 Double Deck Padding Machine

6 Materials encountered when excavating a trench Large Boulders Wet Sticky Material Large Clumps of Clay

7 Screening Problems BLINDING: Sticky cohesive material blocks material from screening through Inefficient Premature Wear Unscheduled Downtime

8 Innovative Padding Solution Rugged, Robust, Two Deck Padding Machine

9 Innovative Padding Solution Rugged, Robust, Two Deck Padding Machine Different deck options Safety Features Patent Pending

10 Single deck screen media susceptible to breaking, with continuous high impact from large stones and rugged material

11 Top deck takes the abuse Reduces the possibility of oversize material penetrating the screen cloth and contaminating the padding material. Bottom deck protected More efficient screening

12 Finger tines on top deck

13 Finger tines on bottom deck

14 Facilitates inter changeability between various screen media configurations.

15 Facilitates inter changeability between various screen media configurations.

16 Total screen area of 11,52 m² Each deck is 320 x 180 cm

17 Summary Track mounted self-propelled padding machine. Two deck screen in a hydraulically variable angle adjustable sub frame. Trench Integrated chute. Lowered pipe Covered pipe Variable speed conveyor operating to either side.

18 XROK Safety Conforms: ISO Safety of Machinery Directives and regulations Functional

19 Safety Features Hydraulically operated hopper sides locked in position Shaped Remote control Emergency stops Warning audible alarm and safety beacons Night lights Battery isolator Umbilical Control System Easily accessibility grease points

20 Maximum Stability 20 º 20º Incline Tilt Forward and Reverse 10 º 10º LHS and RHS Lateral Tilt

21 Standard BS EN ISO 14120: 2015 / V EN new common global standard for fixed and movable guards. Both standards: Probability and consequences; Intended use Hazards present at the machine; Nature and frequency of access

22 Legislates for Foreseeable Misuse Standard EN ISO statistical probability of an unwanted occurrence or failure. BS EN ISO 14120:2015 introduces the concept of the foreseeable misuse and defeat of the guards.

23 Potential Nip Point

24 Potential Nip Point

25 Potential Nip Point In Britain in a recent five year period, 20 miners died in conveyor-belt accidents. Among Mineral Products Association (MPA) members 3 died in the last 4 years. Accessibility to danger zones.

26 Risk matrix Potential Consequences L6 L5 L4 L3 L2 Minor injuries or discomfort. No medical treatment or measureable physical effects. Injuries or illness requiring medical treatment. Temporary impairment. Injuries or illness requiring hospital admission. Injury or illness resulting in permanent impairment. Fatality. Not Significant Minor Moderate Major Severe Expected to occur regularly under normal circumstances Almost Certain Medium High Very High Very High Very High Expected to occur at some time Likely Medium High High Very High Very High Likelihood May occur at some time Possible Low Medium High High Very High Not likely to occur in normal circumstances Unlikely Low Low Medium Medium High Could happen, but probably never will Rare Low Low Low Low Medium

27 Hierarchy of Controls Most effective Elimination Physically remove the hazard Substitution Replace the hazard Engineering Controls Isolate people from the hazard Administrative Controls PPE Change the way people work Protect the worker with Personal Protective Equipment Least effective

28 Assessing the Risk

29 Consider the following XROK conveyor belt travels in the range of 180 meters per minute and can travel in either direction. This means the belt is moving at 3,000mm per second. That is two revolutions of a 450mm pulley. For the average person, the reaction time to an unexpected sensation is about one second. 180 m per min.

30 Draw a tool, loose clothing, gloved or bare hand and arm, into a pinch point before you can react.

31 Potential Nip Point Potential nip point on a padding machine

32 Guard: A guard is a machine element that makes the danger zone inaccessible, by isolating it (Regulation Respecting Occupational Health and Safety) designed with operating conditions in mind.

35 Access to the moving part which is the nip point is now physically impossible. The guard does not impede the operation of the plant.

36 Risk matrix Effectively deals with the foreseeable misuse and defeat of the guards Minor injuries or discomfort. No medical treatment or measureable physical effects. Injuries or illness requiring medical treatment. Temporary impairment. Potential Consequences L6 L5 L4 Injuries or illness requiring hospital admission. L3 Injury or illness resulting in permanent impairment. Fatality.
