Discussion > Talk with your colleagues about it!
  • I once saw a load fall down.
  • If I am doubting whether I have rigged a load properly or not, I will check it with the operator
Introduction

It is every operator’s nightmare: a poorly secured load that is lifted above the construction site and is about to fall out of the crane. You can imagine that if this happens, the hair on the operator’s neck will stand right up. The manner in which large and heavy loads are rigged is carefully chosen. As a result, not many accidents occur with such loads. However, less attention is paid to the manner in which small loads are rigged. In special cases a lifting plan is drawn up, which everyone will pay attention to.

More attention should be paid to loads consisting of, for instance:

  • scaffolding material;
  • boards;
  • beams;
  • wheelbarrows;
  • and pallets etc.

Sometimes when a load is very light, it is difficult for the operator to keep it under control as the lifting block is heavier than the load. Such a load will also be more easily affected by the wind, making it prone to swerve.

It is especially these kinds of loads that are rigged by inexperienced people. It seems like simple lifting work, but it is not! Inexperienced and often uniformed people should therefore not be allowed to carry out such work. A permanent rigger at the construction site, so an employee who has received the proper training and is certified, may rig loads.

It is important that a load that has been rigged cannot simply fall from the crane.  

Risks > What can happen?

Loads that have not been rigged properly:

  • The load can fall from the crane because the lifting straps have only been secured to the frame (Fig. 1);
  • Do not only connect the chain to the yoke, otherwise the contents will be lying loose (Fig. 2);
  • Lifting straps have not been pulled through the loop, as a result the scaffolding planks can slide (Fig. 3);
  • The load can slide, as the lifting straps have only been attached to the yoke (Fig. 4);
  • Employees who have not been properly trained / are not certified are rigging/securing loads;
  • The weight of the load does not match the chains or lifting straps that are being used;
  • The hooks do not properly fit in the eyes.

Measures > What must you do?
  • A permanent rigger on site who has been trained to rig/secure loads;
  • Provide the operator with the proper instructions https://www.geenongevallen.nl/toolbox/hijsen-communicatie-met-de-kraanmachinist.html;
  • Minimaal de opleiding aanslaan van lasten bijvoorbeeld door SOMA Bedrijfsopleidingen, eendaagse opleiding. De opleidingen BLVA (bouwlasten veilig aanslaan) en opleiding hijsbegeleider TCVT W4-08 voldoen ook.
  • klik hier voor de opleiding in de Heijmans Academy;
  • Vanaf 1 januari 2020 zal hier op gehandhaaft gaan worden.
  • uitzondering zijn lasten die worden aangeslagen bij een kraan die een capaciteit heeft onder de 10 Ton meter.
  • geef de juiste aanwijzingen aan de machinist https://www.geenongevallen.nl/toolbox/hijsen-communicatie-met-de-kraanmachinist.html;
  • Use chains that match the weight of the load;
  • Ensure that the lifting hooks fit in the eyes.

The safest way to rig using chains:

  • Connect the chains around the load and to the yoke (Fig. 5);
  • This way the chains will keep the materials in position.

The safest way to rig using lifting straps:

  • The lifting straps have been pulled through the loops on the left and right side, to ensure the load will hang straight. This will prevent the frame from tilting. (Fig.6);
  • If you are using lifting straps, make sure they are pulled through the loops. This way the material is least likely to move around. (Fig. 7);
  • Here the lifting straps have been secured by pulling them through the loop, diagonally under the frames. The frames cannot fall and the lifting straps pull the tubes together. (Fig. 8)

The best method with lifting straps: securing them through the loops
7: Planks kept in place by pulling lifting straps through the loops.
8: Lifting straps fasten the scaffolding tubes to the frame.
