The invention relates to a home lift and a mechanical stopping device thereof. The mechanical stopping device of the home lift comprises a blocking assembly installed on a car frame and a collision plate fixed to a car guide rail. A blocking rod forms a bolt structure on a fixed frame. A first micro switch and a second micro switch are fixed to the fixed frame. When the blocking rod moves to a retracting state, a first switch baffle on the blocking rod triggers the first micro switch, and the lift normally operates; and when the blocking rod moves to a stretching state, a second switch baffleon the blocking rod triggers the second micro switch, the lift is switched to an overhaul operation state, and the stretching end of the blocking rod and the collision plate on the guide rail can be matched for blocking. When the blocking rod moves leftwards and rightwards, the lift cannot normally operate, and overhaul operation cannot be conducted neither. By triggering the different micro switches in the retracting and stretching process of the blocking rod, the position of the blocking rod can be verified, the normal operation and overhaul operation of the lift are ensured, and protectionis reliable; and a mechanical blocking device is arranged between the car guide rail and the car frame, so space is saved.
