How do you secure an IBC container to a rack correctly? Securing, locking and a pre-journey checklist (tractor and wheel loader)

Securing an IBC container to a rack is one of those routines that seem minor in everyday life 10

When transporting water, washing water, liquid fertilisers or preservatives using a tractor or wheel loader, the weight of the tank and the movement of the liquid place a strain on the trailer and its fixings with every jolt. The aim of this guide is to make the securing process repeatable: the same steps every time, without the need for specialised tools, and in such a way that a pre-drive check is easy to carry out even when you’re in a hurry.

Lootu Oy (Pekurinpolku 3, 90450 Kempele) manufactures sturdy metal IBC container racks for tractors and wheel loaders. When the rack is the right size and the attachment points are conveniently positioned, securing and locking the container is a smooth, everyday process – and safety becomes second nature.

Securing an IBC container to a rack: basic principles and risks

Proper securing of an IBC container to a rack is based on three factors: (1) the container is always in the same position on the rack, (2) the fastenings prevent both lateral movement and rotation, and (3) the locking mechanisms ensure that nothing can come loose due to vibration. When all these points are met, the outcome is predictable, regardless of whether you are transporting the container within a yard or moving it to a construction site.

Typical problems arise because the plastic body and metal frame of the IBC react differently to the load. If the straps are “merely tight” but not correctly aligned, the container may start to twist on the rack. Furthermore, the “sloshing” of the liquid increases the dynamic load, particularly when the container is half-full and the route is uneven. Therefore, the lashing must support the container both vertically and horizontally; simply tightening the top edge is not sufficient.

Practical securing: prevent movement and twisting without the need for specialised tools

When the aim is repeatability, make the binding a “standard procedure”: the same straps, the same routes and the same method of tightening. In practice, this means choosing two main ties that form an X-shaped support (crosswise) or, at the very least, a diagonal support that creates distinct angles. The angle of the diagonal support is important: the more the binding acts solely in the vertical direction, the less it resists lateral movement.

When using an IBC with a metal frame, it is advisable to make use of the rack’s designated attachment points – not random points, which may scratch the plastic container or the edges of the cloth. If you have different applications (watering, washing, preservative), create a single lashing pattern and only add a third “safety strap” as and when necessary, such as when the route is bumpy or the speed is higher. The most important thing is that the extra cloth doesn’t disrupt the basic logic.

Also bear in mind that the tank’s fill level affects its behaviour: a completely full or almost empty tank is often easier to control than one that is half-full, as this is when the liquid has the most room to move around. If the nature of the work allows, try to avoid long journeys with a “half-full” load, or take extra precautions and reduce your speed.

When tightening, do so “evenly”: first apply pre-tension to both end straps, then tighten them fully in turn. This prevents the container from becoming skewed whilst you are tightening it. Finally, secure the loose end of the ratchet strap neatly (e.g. with a Velcro strip or a knot) so that it does not rub against the frame and loosen the fastening.

When the suspension prevents movement in every direction, driving becomes “normal” – you don’t have to constantly compensate for the load shifting by adjusting the steering.

Locks and fixing points: ensure they are mechanical

Securing the load is only part of the picture: the fastenings and attachment points determine whether the load will stay intact when subjected to vibration. A good rule of thumb is that every critical function should have a clear “locked/unlocked” status that you can see at a glance. This makes pre-ride checks quick and means you’re not left relying on a hunch.

Tractors (with front loaders or rear lifters) and wheel loaders often exhibit different dynamic behaviour: on a wheel loader, the chassis and load may sway in a different way to those on a tractor, and speeds and turning radii may vary depending on the working situation. Therefore, the attachment points must be such that the slings do not “climb” along the edge, and the angle does not cause the sling to tear. If the scaffold has its own sling lugs or attachment points, use them – they are usually positioned so that the forces are transferred to the frame in a controlled manner.

When working with preservatives or other chemicals, also be mindful of corrosion and splashes: metal surfaces, fastenings and the metal parts of cloths may be damaged if washing and maintenance are neglected. You can find background information and practical safety measures, for example, in the Finnish Institute of Occupational Health’s summary on chemical safety: Finnish Institute of Occupational Health: chemical safety.

Pre-drive checklist (tractor and wheel loader)

The pre-departure check is the step that distinguishes a “rushed” solution from professional transport. The idea behind the checklist isn’t to create more work, but to remove uncertainty: when you go through the same list every time, you’ll spot any discrepancies straight away. This works just as well in day-to-day farm operations as it does on contract work in Kempele, Oulu, Liminka or even Kokkola.

Keep the checklist short and straightforward. First, check the items that affect load security (straps, locks, rack attachment to the vehicle), then the items that affect leaks and environmental risk (valves, hoses, caps), and finally visibility and the route. Also get into the habit of stopping briefly after the first 200–500 metres to check the fastenings again – especially if the load is new, the rack has been changed or the route is uneven.

When you combine the list of errors with this checklist template, you’ll quickly have a standard that you can also teach to a cover teacher or a member of staff.

A replicable operating model for various applications (water, washing, preservatives)

Repeatability stems from the fact that the fastening system has a single basic design with only a small number of controlled exceptions. Water and wash water are often more “forgiving” than preservatives, but the safety requirement remains the same: if the tank moves, it will damage the rack, wear out the cloths and increase the risk of accidents. That is why the basic design should be built to withstand the worst-case scenario – in other words, so that it works even when the load is challenging and the working day is long.

In contract work (e.g. in Oulu, Vaasa, Joensuu or Kuopio), transport distances, uneven surfaces and stops become particularly significant. In such situations, even small routines, such as “stop and check after the first manoeuvre”, pay for themselves. On a farm, on the other hand, repeated short movements can tempt drivers to take shortcuts – which is why a visible checklist and a standardised loading route are particularly important.

The most common faults and quick fixes (as well as maintenance to prevent recurring problems)

Many problems appear the same whilst driving (“the tank moves”), but the cause may be completely different. If the straps repeatedly come loose, the fault isn’t always with the strap itself – it may be that the attachment point is in the wrong place, the angle is too small, or that the tank isn’t sitting flat on the rack. That’s why it’s worth practising “troubleshooting”: what the movement tells you and what to change first.

It is good practice to carry out a quick weekly check of the work platform and fastening equipment: inspect the welded joints, check for sharp edges, clean off any spatter and replace worn cloths immediately. Consistency is also achieved by ensuring the equipment is in the same condition every morning. If you need guidance on extending the service life of your equipment, include a rack inspection and maintenance routine in your daily checks (for example, drying after washing and light maintenance of moving parts).

Lootu Oy’s concept is simple: when a rack is designed for practical use and the IBC container is secured to the rack using the same method every time, it makes day-to-day life easier for both farms and property maintenance teams.
