I used a playmobil actuation set ( 15 euros) part number 5556 apparently still on the market.
The hoist consists of a totally home made winch and a Playmobil electrical actuation set selected for several reasons:
- actuator delivered with its control box avoiding to design one control circuit and integration into a box
- actuator fitted with an end stroke torque limiter avoiding breakage risk
- quite acceptable torque. This hoist lifts 200 grams at hook level
The winch is made of wood.
The 2 side uprights are bored together at a wood rod diameter dimension creating the winch drum.
The shaft axis is thus properly done.
The liaison with the actuator is made with a small plastic tube providing an additional torque limitation

My first design was to create the big hole in the hoist plate as I believed the rope should be able to move freely. It is wrong , it is better to have a small hole to guide the rope in the right place in the midle to move the bucket.
