Technical Field

[0001] The utility model belongs to the technical field of elevator components, and in particular relates to a lower through-beam structure of a heavy-load freight elevator, which is installed below a car frame. Background Art

[0002] The elevator car frame is a structure used to support the car and the people and cargo inside it, and to move the car up and down. It is composed of components such as vertical beams, upper beams, lower beams, and bracing. Existing elevator frames generally lack a lower through beam or have only a single lower through beam. For heavy freight elevators, the frame is easily compressed and deformed. Alternatively, when the safety clamp activates or the elevator bottoms out and hits the buffer, uneven force is applied, which can also easily cause deformation. When heavy cargo is first entering or exiting the car, the existing elevator frame cannot provide sufficient support at the front and rear entrances and is prone to deformation, so the elevator frame needs to be sufficiently strong.

[0003] In view of the above-mentioned prior art, it is necessary to improve the car frame structure of existing large-load freight elevator.
