Sturdy construction arm. We have a wood stove where we rent and we lift wood, of course you will also need to get the electric motor that will be mounted on the arm. You will also need to get a wall mount or a scaffold-type base to securely support the arm along with the motor.
The only mistake we made was that we didn't pay much attention to the length of the arm in our order, and when we lift the wood up, they are not far from the balcony and with the slightest breeze, they slightly hit the railings of the floor below. You should get a slightly longer arm.
The other guy tells me: I bought on the 6th floor without an elevator a month ago, can I set up such a motor for groceries? And I tell him: buddy, you don't live in an apartment, you live in the Meteora and you'll need a motor with a net to lower the kids for school too. And I continued: all the good old football players came from apartment buildings, 6th and 7th floor without an elevator. Ok, he says, I'm hanging up.
