Staircase floor lifting device.
In the homes where elderly people are accustomed to living, the knee joints are subjected to a lot of stress when going up and down stairs, especially when going down them, which causes frequent falls and can lead to serious health problems such as fractures, hospitalization, and even becoming bedridden or experiencing the progression of dementia. [Solution] Hydraulic bags containing hydraulic oil are placed under the treads of each staircase, and the hydraulic bags are connected to each other by hoses with control valves. When the operating lever inside the handrail is gripped, the wire opens the control valve, and the hydraulic oil is pushed out by the user's weight, causing the treads to descend. The pushed-out hydraulic oil is injected into an empty hydraulic bag container on the floor below, causing the treads on the lower floor to rise and be at the same floor height. This provides an inexpensive, non-powered elevator "specialized for descending," allowing users to easily descend to the floor below without bending their knees.

An installation device for precast concrete stair components
This invention belongs to the field of prefabricated building technology and discloses an installation device for precast concrete stair components, including a base. Through the cooperation of a positioning component and a hydraulic mechanism, a rubber plate presses against two support plates, causing the lower end of the rubber plate to squeeze the hydraulic oil inside the hydraulic cylinder into the telescopic rod, forcing it to extend the guide rod. The guide rod then moves the hydraulic oil between itself and the sealing plate, causing the oil pressure to pass through a metal rod and compress the air between the sealing plate and the sealing plate. The telescopic end of the hydraulic cylinder moves slowly, preventing damage to the precast concrete stair components and the device during movement. The hydraulic mechanism drives the support component to lower the positioning component and the precast concrete stair components to a suitable installation position, reducing the time spent installing the stair with a crane and minimizing the labor required to manually move the precast concrete stair components and align them in their installation positions.
