The invention relates to mechanical equipment for hoisting a steel structure member. The mechanical equipment comprises a tower body, a tower top, a suspension arm, a weighing arm, a counterweight, a rotary control mechanism, a mobile control mechanism, a balloon container, a hydrogen tank and a main controller. In steel structure ship hoisting, the main controller starts a gas controller, the gas controller provides hydrogen for the balloon container, and the balloon container drives the suspension arm to rise so that load on the suspension arm and the weighing arm is reduced and safety hidden troubles caused by aging of the weighing arm and the suspension arm are avoided.
