Hi all. 

I have a query about radio controlled cranes in a workplace. I once trained on them many years ago and seemed to remember that the control unit must be kept safe when not in use. This is to prevent unauthorised use. We actually used a castel key system and a boxed up arrangement for the contoller. I would like to know if there is anything in legislation (PUWER or otherwise) to confirm either way that these control units must be kept so. I know that there are radio controlled locomotives and various items of mining equipment that can be radio controlled, so there must be something somewhere.

Cheers

You can’t lock a wired pendant up, so why lock a remote pendant, apart from the potential lack of line of sight of the load?

Why would you want to do this anyway? Is your workforce so untrustworthy? I think you are seeing a risk where there isn't one. In nearly 40yrs of being of being in the engineering sector I can't readily think of any incidents relating to unauthourised use of cranes.

Must admit that one caused quite a few engineering headaches over the years at various sites and various powered hoists.

We had people selling clips that held the E-Stop buttons pushed home, we had split plastic boxes offered that shrouded the controller, we had metal lock boxes that fastened to the wall.

Then one bright "spark" pointed out that if you isolated the power supply as part of a lock out tag out system it didn't matter who had the controller nor what they were doing with it as there was no power to move the crane.

A gantry crane in a factory is not self-propelled work equipment though,

Self-propelled needs a means of power independent to the electrical supply of the building.

Taken from the ACOP

Self-propelled mobile work equipment

237 Self-propelled mobile work equipment is work equipment which is propelled by its own motor or mechanism. The motor or mechanism may be powered by energy generated on the mobile work equipment itself, for example by an internal combustion engine, or through connection to a remote power source, such as an electric cable, electric induction or hydraulic line.

You beat me to it Paul. How you can decide a wired in crane to a factory is 'self propelled'....

Self propelled means something like a forklift truck, mechanical handler etc

We have used radio control tyre gantry cranes similar to the ones seen here (just smaller to fit the facfory)

https://www.mph-cranes.com/our-product/rubber-tyred-gantry-crane/

and being used in and out of the factory gas powered like an FLT.

I think that the next step in this discussion is to identify the type of crane being discussed.

Is it constrained to rails fixed in the building, or free moving, engine driven on wheels, is it fed by bus bars, does it have a trailing supply cable etc.

I have seen those cranes and worked with them Roundtuit, so in fairness you have a point.

As far as I can tell, not much point in commenting until I know what type of factory crane the OP is asking about.

For the purposes of PUWER regulations 25–30, mobile work equipment is any work equipment which carries out work while it is travelling or which travels between different locations where it is used to carry out work. Such equipment would normally be moved on, for example wheels, tracks, rollers, skids etc. Mobile work equipment may be self-propelled, towed or remote controlled and may incorporate attachments.

I see nothing about it it being exempt "if confined to rails" still "Traveling" - but then it does not define location. For me that could be part of a large wharehouse not just between geographical locations. Reguradless of this if someone is injured when such equipment is being used by an unortharised person, the enforcer will just hit you with general duties.

None of the legislation really matters until there is an incident and it goes to court. Then the specifics of the law come into play. What we as H&S professionals need to look at ( and this related to any every piece of work equipment) is what would happen if some unauthorised pillock, got their hands on this piece of kit and assuming mayhem might occur what is the easiest, most effective way of preventing this.  The legal stuff is for the lawyers ;we should be dealing with practicalities.

We find these easy to manage.

Ours are mains powered with an isolator switch on the wall. The design of the switch allows a padlock to be fitted.

Therefore when not in use, these are isolated with a padlock to prevent unauthorised use, with the padlock keys managed by the team leader. No need to lock away controllers.

Monitoring and behavioural audits check that this is being correctly managed.

I did encounter an issue once where there were two of these cranes, not in sight of each other, and an operator picked up the remote control for one of them believing it to operate the other one.  Some extra locking up happened after that.

You stick with the definitions you want, and I'll stick to what the product legislation and product standards define these machines as.

It's up to you.

I know which product standards and legislation these different kinds of machines would be assessed to and what I have assessed them to, and these assessments have been put in front of HSE for various different reasons, with no come back on us whatsoever.

So we will have to agree to disagree.

However, I know which camp I am going to stay in, and that is not the one that you are in, for vary valid legal and engineering reasons, based on sound engineering judgement and my experience of these machines.
