Technical Field
The invention relates to a passenger elevator, in particular to an elevator for sightseeing.
Background
An elevator is a vertical elevator powered by an electric motor and used for carrying people or goods in a multi-story building. Elevators have become important building facilities and are indispensable in high-rise buildings and public places as transportation vehicles in the vertical direction. With the improvement of the whole national economic strength, the living consumption level of people is obviously increased, and the demand for elevator individuation is increased. Some large-scale high-end hotels require that the left and right sides of the elevator are sightseeing glass and any elevator component or derrick cannot be seen due to design requirements, and the arrangement of the elevator with a common structure cannot be met, but only a knapsack type arrangement can be adopted. However, the conventional knapsack elevator can only be used for a household elevator with a small number of passengers and a low floor due to the limitation of the structure and the installation position, the rated load of the conventional knapsack elevator basically does not exceed 400kg, and the speed of the conventional knapsack elevator is 0.4 m/s; if the load and the speed are increased, the unbalance loading of the elevator is more serious, even an empty car can incline, and the unsafe conditions of inclination and unstable operation are easy to occur under the condition of full load.
