I have a cabinet with a door that opens down about 90 degrees.
The door weighs about 12 kg and right now you need to be cautious when opening it. You also have to hold it with your knee when it's fully open, otherwise it falls to the floor.
Gas springs are good for holding up and pushing up, but for damping the descent? You might as well have mounted lines or nylon straps there.
You should be able to use these: 373.66.611-HE from the same company. This way you get a clear stop and braking function.
Just wondering why your gas springs don't stop the flap in the lowered position.
Assuming you chose the type of pull, to get the function you want to achieve, you might need ones that can handle heavier doors, otherwise no solution as far as I know, it's pretty good pull there,
depends a lot on the angle they have in relation to the mounting, I think that with mounting on halfway up the door makes it weigh double in the operation for the springs,
Maybe with a bike tube as a spring, just a little problem attaching it
Yes, they are probably suitable for 12kg, but there is a lever in the door that makes it physically heavier. Think about how it is with a pry bar; you can lift a large stone of 200 kg by using a short piece closest to the stone and a long piece above, the lever is powerful. That's probably what's causing the issue for you. If the cylinder is attached at the top of the cabinet and at the outer edge of the door, the door weighs 12kg, in the middle perhaps 20 kg in pulling force.
In other words, do I need gas springs that can handle more than 12kg each?
I found this page but unfortunately, it does not show a configuration for a folded-down hatch where the gas springs are on the inside of the hatch https://www.gasfjadershop.se/gasfjaderberakning/
Probably that's what you need, a tip to avoid buying the wrong thing again, call them and ask so you get the right stuff, that's the best, they know everything, measure the door in all dimensions first before you call, they'll probably ask about that.
Yes, they are probably correct for 12kg but there is a lever in the hatch that makes it physically heavier, think about how it is with a crowbar, you can lift a large stone 200 kg by using a short piece closest to the stone, and a long piece above, a lever is powerful, That's probably what's causing the problem for you. If the cylinder is attached at the top of the cabinet and on the outer edge of the hatch, then the hatch weighs 12kg, in the middle, maybe 20 kg in tensile force
Without answering the actual gas spring question, I must nonetheless point out that this is wrong. The hatch in this case weighs 12 kg and cannot weigh more. There is no lever effect that can influence here.
A counterweight in a line that runs over a wheel? Have that solution on a skylight at work. It might be tricky with the space, the line needs to be longer than the cabinet is tall, I realize.
Without answering the actual gas spring question, I must still point out that this is incorrect. The hatch in this case weighs 12 kg and cannot weigh more. There is no lever effect that can influence here.
Put your fingers at the very top and press with 1 kg, you say OUCH OUCH, then move your fingers to the middle and press with 1 kg, you probably won't say OUCH OUCH but rather lose your fingers because of the lever effect.
