The invention discloses a bulk container loader for a container. The bulk container loader mainly comprises a base, a tripod, a container support frame, a lifting cylinder, a box body bracket, a box closing mechanical arm, a weighing sensor, a triaxial gravity inductive sensor and a miniature display screen. The bulk container loader for the container is high in bulk loading speed and capable of increasing the transporting efficiency of the container; and the weights of goods in the container can be known in real time, so that the overloading risk of a transporting vehicle is avoided, and the transportation safety of logistics is ensured. The bulk container loader for the container is simple in structure, reduces the complex workload during container operation and has a wide application prospect in the logistic field.
