Are there safety requirements for outdoor hydraulic lifts

[jerk]

I have an idea to build a height-adjustable surface in the deck that will be controlled by a hydraulic lift table. On it, there will be a pool cover. When you want to swim, you push the pool cover into a booth that then lowers under the deck, leaving only the deck floor. The question is whether any safety devices are required to build this besides what's included in the hydraulic lift table. I certainly don't want 1000 kg of deck/pool cover to risk pinching the children's fingers.

If you turn off a hydraulic lift table, does it stay in that position or sink down to the bottom?

My lift table sinks very slowly, maybe 5 cm per month.
Lift tables likely have a hose rupture valve so they shouldn't be able to sink abruptly.

That sounds good. Are there any inspection requirements regarding hydraulics in the same way as with the chimney sweep and stoves, or is it free for a DIY construction?

I believe truck beds and tractor buckets must be fully lowered before they are allowed to leave. If the hydraulics fail, serious injury can occur.

Hello!

Under lift tables, there should be a pinch protection that stops the table if something gets pinched when lowering. Then you can have a similar system in the booth as well.

We want to see pictures of this build!!

Yes, there is a crush guard on the lift table, but I will mount the lift table 80 cm below the wooden deck, which will have two levels, so I need to come up with a solution that moves the safety device to the edge of the wooden deck. Maybe fix some type of rubber strip with an integrated switch like on garage doors.
