Hello All, I am in the process of building a layout whose platform can be winched up to the ceiling. What I am looking for is a safety feature where the platform can be physically locked in place with maybe 4 latches.
The winch mechanism will have a ratcheting feature which will be the primary locking mechanism that will hold it in place. But once it is winched up into it's recessed space, I want to lock it in place (maybe manually or some kind of solenoid locks) so that for whatever reason if the ratcheting mechanism slips or fails, the whole thing shouldn't come crashing down.
Any ideas you may have are welcome.
Thanks |

Hi Gautham, is the winch manually wound by handle or is it elecctric?

How far below the ceiling will it end up? Close enough for a simple hook and eye to reach it? You could even put blocks in the ceiling to reduce the distance.

Try a big box hardware shop &look in the plumbers /pipework area for circular rubber seals used in vitreous pipework, used by plumbers as a seal at joins . Also check out in the storage area for locking devices with a flip over piece usually used on gates where a padlock can be inserted on one side . A RV shop also would have good range of device for the boxes tradies use on the back of their trucks.

Take care I like Marklin and will defend the worlds greatest model rail manufacturer. |

The platform will be around 350mm. There will be a false ceiling made of plywood surrounding it. The platform will sit flush with the false ceiling when it is fully up. The height of false ceiling is 350mm. |

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
So many trains and so little time. |

What is the bottom of the layout made of? If it is wood of some and the ceiling is the same you could use simple slide bolts or if they are not solid enough for that you could frame both with wood to use the slide bolts. If the problem is the height of the ceiling, not sure what the 350mm is a dimension of, you could use hopper window hardware with a window pole to operate it: http://www.parrettwindows.com/hopper-multipoint-3/

Hi Gautham, Because the underside of the lifted layout is flush with the ceiling, yes a joiner can figure out a simple strong-enough swivel bracket to keep the layout in place. That may not look very aesthetic. But I really believe that the electric winch will not allow the layout to fall, because in most cases they are a geared mechanism with enough resistance to achieve that. Kimball |

I am having another company which manufactures motorized rolling shutters provide me with the lifting mechanism. |

Well you might be able to use the solenoid driven door latches used on front doors that can be release by an electrical signal (buzzed in) and place several of those around and recessed inside the perimeter. Then when you need to lower you first press the release button, and while its buzzing (pulled in the release pins) you activate the electric lowering mechanism until the latches are cleared. Better still, design the system to have the lowering mechanism auto-engage the buzzer latch release, and once the lowering mechanism clears them a switch shuts down the power to the buzzer latches. |
