Seven steps to safety

Step 1- Setting Out

The Engineer instructs the operative of the coordinated positions for setting out the kerb line. These positions would then be marked on the ground. The coordinated positions would usually be located at 10 metre chainages.  

 Step 2 – Setting up ‘Pinsafe’ 

• Position the base of ‘Pinsafe’ adjacent to the Engineers mark.  
• Loosen the ratchet lever. • Raise the cross arm to a 45◦ degree angle. 
• Tighten the ratchet lever to support the cross arm. 
• Loosen the pivot knuckle to ensure positioning of the pin onto the Engineer’s mark. 
• Check ‘bulls-eye’ level.
• Tighten all levers, ensuring they are all turned down in a ‘6 0’Clock’ position, which ensures a safe working location.     

Step 3 – Stabilising ‘Pinsafe’  

In order to ensure stability, ‘Pinsafe’ requires a counter balance weight. A kerb is recommended to provide this counter balance; although any item of a similar weight will suffice.   

Step 4- Setting Levels  

When the Engineer has set a level on the ‘Pin’, this will be indicated by the application of tape, to the ‘Pin’ at the desired level.  

Step 5 – Stringing Line  

The kerbing operatives will apply a string–line from ‘Pinsafe’ to ‘Pinsafe’, following the Engineer’s tape-line, in order to achieve the correct level.  

Step 6 – Kerb Laying 

At this point kerbs can be laid using normal working methods.  

Step 7 – Removal of ‘Pinsafe’ from working area and safe storage.  

On completion of kerb laying;  

• Ensure tape-line is removed from ‘Pin’. 
• Undo the ratchet lever and remove setting-out ‘Pin’. 
• Place setting-out ‘Pin’ into its storage area. 
• Remove ‘Pinsafe’ from working area.
