Description

The invention relates to scaffolding and can be used both in construction and in other areas requiring the maintenance of objects at height.

The purpose of the invention is to provide work in hard-to-reach places.

FIG. 1 shows the layout, the position of FIG. 2, the same transport position; in fig. 3 - unit for fastening the upper platform to the rotary section; in fig. 4 - section A-A in FIG. 3j in FIG. 5 — knot; 5 outrigger fasteners; in fig. 6-10 - stages of unfolding the plug in the working position.

The collapsible tower includes a base 1, on which are fixed 20-cal 2 ca 2 into outriggers 3. The base is equipped with chains of extensions 4, on which there are lanyards 5. To base 1 of the ball-- the rotary section 6 is fastened securely on pins 7 in bearings 8. In the lower 25 part of the section in the hinges 9 a platform 10 is attached. In the upper part of the rotary section there are articulated rotary plates 11, on which rollers 13 are attached to the axle 12 13. The rollers 13 enter into the lateral slots of the platform 14 having a strut 15, a railing 16, 17 And a jumper 18. For installing the rotary section 6 in the tikalnoe position of the base is pivotally affixed if rod 19 "

The device works as follows.

Having installed it in the right place, the outriggers 3 from the transport position are installed in the working position with the help of their flywheels.

a gap is created between the surface of the floor and the wheel of the tower. The ends of the extension chains 4 are fastened to the floor surface. By rotating the turnbuckles 5 of the stretch chain 4, the tension is tightened to r to ensure tight fixation of the floor of the floor. After releasing the pulls 19, turn the rotary section 6 to a vertical position and fix the pups 19 on it. Lower the pad 10 into a horizontal position. By turning the plates 11, the output t of the platform 14 to a horizontal position. Push the platform 14 up to the stop and secure the strut 15 to the rotary section 6. The rail 16, 17 and the lintel 18 are installed.

The tower is brought to the transport position in reverse order.
