Stage building process

Everyone's stage steps: first, set the two legs of the stage in the approximate position on the ground; Insert diagonal tie rods on both sides into the pins on the legs set above, and remember not to close the check valve; Then buckle the table frame into the U-shaped groove above the legs, and 1 the stage is assembled. And discharge one leg; Then two groups of diagonal tie rods are selected to connect with the original legs, and the legs are fixed; Then unfold the table frame, with a leg between the two table frames, and both table frames are placed in the U-shaped groove; By analogy, if the next column can be extended indefinitely, it is also assembled in this way. Insert the diagonal tie rods on both sides into the pin on the leg, and do not connect the check valve; The table frame should also be buckled into the U-shaped groove above the legs before assembling the second stage group. And discharge one leg; Then two groups of diagonal tie rods are connected with the original legs to fix the legs; Finally, the table frame should be laid, and one leg between the two table frames should be put into the U-shaped groove.
