PROPER LIFTING OF AGGREGATE BAGS


  • Aggregate bags are used for soil, sand, gravel etc.
  • The bags are made of nylon material which can be torn and split quite easily if mishandled during transportation or storage.
  • During lifting operation, the loops should be straight and not an angle and the hooks should be of sufficient size not to crush the loops.
  • Majority of bags delivered to site are certificate to lift 1 Tonne of aggregate by a Fork Lift. The term 1 or single is used to described their certification, meaning once delivered and emptied they are scrapped and not used again.
  • Other multi use bags are available with certification however they require the use of a lifting frame or spreader bars and inspection of the bag and loops prior lifting.
Sample photo below shows proper way of lifting aggregate bags.


Operators on some sites had problems regarding lifting of aggregate bags.

What to do when you are involved in lifting aggregate bags?
Common Sense Approach:
Apparently it is relatively low risk to lift aggregate bags if they are kept below head level or height and moved a short distance across the site. If aggregate bags are being lifted higher than the head level then the operation will be at high risk as the bag could split or a loop fail and the contents could be scattered all over the site onto the workers below with the possibility of injury or damage.



Safe practice for lifting bags above head level or height:

Lift the bag off the trailer, keeping it lower than the head level and land it either onto a pallet, stillage or a certified lifting skip. Then use pallet forks and a net, the stillage or skip to lift the material above head level to where it is required. The same full bags which require lifting down should also be transported in this manner.



IMPORTANT REMINDER:

  • Aggregate bags should not be used as the sole means of lifting materials to upper areas.
  • Lifting operations are the responsibility of the crane user or operator and their Appointed Person at site.
