Personally, on windy days working outside, I use 2 methods, depending on space. The outside extremities of the chicane and restrictions for stacking/de-stacking: if using standard pallets 1200 mm x 1000 mm, standing on the 1200 mm side, I insert another standard pallet 1000 mm face into the rear of the 1200 mm upright on the middle plank of the base of the cruciform pallet. For the inside of the chicane or in places where there are restrictions, I use a strap of webbing with a spring loaded steel clamp clip on one end to hold the corners upright. These always work well 99.7% of the time!

I've read that pallets upright is a safety concern, although this is right, it is also the instructors role to ensure trainees observing training (Not testing) are in a safe place, but can still see and hear. I attended a site and was told I could not do this, and I had to lie the pallets down, so, I agreed, providing the company issued me with enough pallets to make the restriction of the chicane to a sufficient height. They allowed me to use my straps when I asked for 70 pallets just for the chicane.

The pylons don't last all that long when the rookies drive over the cones, twist back and forth, back up, get the cones caught underneath the forklift, and we have to pull and tug to get them out while a more competent person is at the wheel twisting and turning the forklift.

I have always felt that the purpose of a trainer at the end of the day was to help ensure that your trainees come home safely at the end of the day. It seemed to me that these forums were a safe place for the friendly exchange of ideas and experience. I offered my thoughts in answer to an openly posted question.
To answer PMac13 I have multiple accreditations valid in Alberta, Canada and the US as well as 42 years of experience in this industry. (I retired last year)
I appreciate learning that cones would not work in the UK as you have specific requirements about them. It may interest some of you to know that a pallet standing on edge is a safety violation here. Open discussion, exchange of thoughts and ideas are always welcome. Cheers all.

Incredible.
You probably did mine!
I'm aiming to get my CAT 4 at some point. Wish me luck!

Don't even go there started at 19 so its actually 33 years as an instructor and 30 years as a tutor! I've lost count of how many instructors I've trained although a guy recently recognised my name and told me i'd done his original 10 day instructor course in 1997!

Liftdog, cones would work but here in the UK, the requirement is to not leave any gaps in between.

I think all of the accredited bodies don't allow any gaps in between.
It truly is a nightmare but as you said, needs to be done.
Works sometimes but not always, especially when the site has crap pallets.
30 years eh? Makes me feel young being training for just over 4 years lol

A common problem in the UK! Not sure who (or if) you are accredited with but certainly the ITSSAR syllabus says that c ones aren't suitable because of the gaps between etc...

Having faced this problem for over 30 years now (god that makes me feel old) I've done various things, mainly laying concrete blocks across the base of the pallet or wedging another pallet against it to hold it up. Not ideal but needs must sometimes!

Hi Sufikh, I use tall traffic cones. They work in multiple environments and are easy to transport to job sites. Good quality cones will recover from the occasional mistakes your rookies have. Hope this helps, cheers.
