The invention relates to the field of spanning frames for electric power and communication engineering, and particularly discloses a portable spanning frame which comprises a column body, a first ascending rod, a second ascending rod, a third ascending rod and a fourth ascending rod are arranged in the column body, the portable spanning frame further comprises an inhaul cable mechanism, and the inhaul cable mechanism comprises a hand-operated winch, an external pulley and a built-in pulley block. The built-in pulley block comprises a first built-in pulley, a second built-in pulley, a third built-in pulley, a fourth built-in pulley, a fifth built-in pulley and a sixth built-in pulley, the inhaul cable mechanism further comprises a steel cable, and elastic locking mechanisms are arranged outside the second ascending rod, the third ascending rod, the fourth ascending rod and the column body. The elastic locking mechanism comprises an upper locking hole, a lower locking hole and a lock pin; according to the invention, the four ascending rods are controlled by the hand-operated winch and the steel cables to carry out segmented lifting and telescoping, so that the crossing frame can be lifted to a proper height in a mountain and other areas which are inconvenient to be connected with a power supply, and the crossing frame can be quickly built.
