The utility model aims at providing a proof warp rises, the structure balance of anti -canting. For realizing the proof warp of purpose rises, the structure balance of anti -canting, and its characteristics are that the structure balance includes weighing platform and at least three sensor, the weighing platform has at least one limit of rolling that is used for on the wheel balance and balance down, on the orthographic projection face of vertical direction, projection that the straight line at arbitrary one projection place of rolling the limit passed two at least sensors, the projection that perhaps has two sensors at least lie in the wheel rolled the straight line at the projection place on limit for arbitrary one same of directive of projection that rolls the direction of motion of balance under the limit one side totally. The utility model discloses the moment that makes weighing platform perk, upset when the weighing platform edge receives great pressure has been reduced to prevent the perk and the upset of weighing platform, reduced the loss of sensor, improved the reliability, guaranteed the service precision of balance, prolonged the life of balance.
