An Unexpected Release of Energy!

What happens when an unsafe twitch combines with a non-conforming extension bar in a constricted area?

NOGGIN INC980 27/04/2018 – LTI.

Description – A truck driver was re-tensioning his load before entering onto the public road and pulled down on the belly chain twitch.  As he levered the twitch it came up against the dolly wheel, which prevented the twitch from locking.  When the driver tried to remove the bar, the twitch was still under tension and it flung back and hit him in the forehead above his eye. 

Injuries – Laceration to forehead (5 stitches) – secondary infection, ongoing dizziness.

Benefit from Industry Best Practice…

The Log Transport Safety Council (LTSC), in conjunction with the forest industry, has gone to great lengths over the last 3 to 4 years to improve safety around the task of load tensioning, to the extent it designed and manufactured a safer device which has been in use for several years now.  The resulting recoilless twitches and ratchet type tensioning systems are recognised as safer solutions than the type of device that was in use on the truck in question at the time of the incident.

A recent audit of 286 Central North Island based logging trucks found six (2.1%) without recoilless twitches and two (0.7%) with non-compliant extensions. Of interest was the fact that the non-compliance was mostly found in older vehicles entering the local system from other regions.  The conclusions are as follows:

  •         The use of non-compliant plant and equipment often leads to poor safety outcomes!
  •         There is always a risk around older plant entering our system – check and correct it.
  •         The LTSC is doing a great job – we should be quick to apply its recommendations.
  •         If unsure about the status of plant – undertake an audit of it.
