The second aspect of the utility model provides a car, including the carriage body and the elevator load bearing mechanism 200 of any one or more of the above-mentioned embodiments, elevator load bearing mechanism 200 installs in the top of the carriage body.
Because the lift car adopts the lift bearing mechanism 200 of any one of the embodiments, the load bearing strength of the lift bearing mechanism 200 is higher, so that the load of the lift car can be increased, and the large-tonnage design of the lift is realized.
The third aspect of the present invention also provides an elevator, including the car of any one or more of the above-described embodiments.
Because the elevator adopts the lift car of any one of the embodiments, the large-tonnage design of the elevator can be effectively realized.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
