The span of the mobile scaffold mast shall comply with the relevant regulations and cooperate with the cross-support specifications. The net distance between the pole of the portal frame and the wall shall not be greater than 150mm. When the distance is greater than 150mm, the safety measures for the inner rack panel or other exit protection shall be taken. Both the inner and outer sides of the gantry should be provided with cross supports and should be locked firmly with the locking pins on the gantry poles. The upper and lower gantry must be assembled with connecting rods and locking arms. The connecting rod diameter should be smaller than the inner diameter of the vertical rod. ～2mm, on the operation layer of the scaffold shall be continuously covered with the hanging buckle type scaffolding plate matched with the gantry, and the baffle plate is fastened to prevent the scaffold plate from falling off and loosening.

Construction elevators are often referred to as construction elevators, but construction elevators include a broader definition and construction platforms also belong to the construction elevator series. The simple construction elevator is composed of the car, the drive mechanism, the standard section, the attached wall, the chassis, the fence, and the electrical system. It is a manned cargo construction machine that is often used in the construction. Because of its unique cabinet structure, It is comfortable and safe to ride. Construction elevators are usually used with cranes on the construction site. Generally, the load is 1-5 tons and the operating speed is 1-60 M/min.

When the height of the scaffolding is H≤45m, along the height of the scaffolding, the horizontal rack shall be set at least two steps. When the scaffolding height is set H>45m. The horizontal shelf shall be set at each step. Regardless of how tall the scaffolding is, it shall be set at every corner of the scaffold at the corners and at one end of the span and at the break. The horizontal shelf shall be continuously set within its setting level. When the scaffolding height exceeds 20m, a horizontal reinforcing bar should be set at every step outside the scaffold and should be set in a horizontal layer with a wall member. The horizontal horizontal reinforcement bar should be set to be continuous and form a horizontal closed loop in the scaffold. The lower end of the bottom gantry should be sealed. The inner and outer sides of the gantry should be equipped with long sweeping poles. The horizontal reinforcing rods should be fastened with fasteners and truss poles.

During construction, attention should be paid to the fact that unmatched masts and fittings must not be mixed and used in the same scaffolding. When the masts are installed, they should extend from one end to the other, and the erection direction should be changed layer by layer. The horizontal and vertical adjustments shall be made so that the scaffolding shall be continuous along the perimeter of the building and be erected in a synchronized manner to form a closed structure around the building. If it cannot be closed, additional wall elements shall be provided at both ends of the scaffold.
