The invention discloses a large-tonnage freight elevator without counterweight. The large-tonnage freight elevator comprises two lift cars (1) arranged oppositely. The top of each lift car (1) is provided with two diversion sheaves (2) symmetrically. The upper portions of the diversion sheaves (2) are connected with a traction sheave (4) through a traction cable (3). A plurality of guide rails (5) distributed evenly are arranged on the two sides of the lift cars (1). The guide rail (5) located between the two lift cars (1) is connected with the two lift cars (1) simultaneously. A plurality of straight girders (6) are arranged on the outer side of the lift cars (1). Underbeams (7) are connected with the bottoms of the straight girders (6). Cross-shaped diagonal jackstays (8) are arranged between every two adjacent underbeams (7). Diagonal drawing bars (9) are connected between the diagonal jackstays (8) and the straight girders (6). According to the large-tonnage freight elevator, the two lift cars are arranged side by side, so that the large-tonnage freight elevator can carry cargos alternatively, and the weight can be balanced mutually as well. The large-tonnage freight elevator not only is capable of improving the carrying capacity and the cargo carrying efficiency, but also has the advantage of being good in operation stability.
