LANYARDS






       How does the

       ENERGY ABSORBER WORK ?

       In the event of a fall the special webbing inside the Energy Absorber
       opens up. This opening of the webbing takes up most of the jerk which
       is felt as an impact when a fall occurs. Hence finally very little jerk is felt
       on the body of the worker.                                    Smooth free fall
                                                                     with Energy
       We can therefore imagine that if this Energy Absorber is absent   Absorber
       from a fall protection system, the forces which are felt on the body
       of the worker can be very high and can result in injury.

                                                                                                  A jerky fall

        What Should be the Length

        of a KARAM FALL ARREST LANYARD

         The  standard  maximum  length  of  the  Fall  Arrest
         Lanyard is 2 meters. Important thing to note is to have
         a lanyard long enough to be user friendly, however,
         kept  as  short  as  possible,  to  minimize  the  free  fall   Total length of KARAM Fall Arrest
         distance.  All KARAM  fall arrest lanyards are tested       Lanyards should not exceed 2m.
         and certified as per EN 355:2002 for their maximum
         length of  2m.

          It is extremely important to know the fall

          Always check for the minimum Fall-

          hitting an obstacle below is not there.
          In  the  worst  case  where  the  user  has               1.0m                            1.0m
