00 The invention relates to devices intended for clamping and pressing-in, preferably, mainly furniture parts, as well as for lifting loads that are on tape or role: portsorterachl. St. No. 1022944 a pneumatic elevator is known, including an elastic air-tight non-permeable arm Air-suction air inlet, a support J / insert placed in the sleeve, its length equal to the length of its horizontal section in its working position, and the insert is made through the hole in which the air inlet Tl is installed. A disadvantage of the known pneumatic lift is the presence of cavities between the side surfaces of the insert and the inner side surfaces of the sleeve in its initial position, for filling which require additional szhats / th air, i.e. the presence of lateral cavities increases the flow of exhausted air and, accordingly, a snf-ss hoist speed. The aim of the invention is to reduce the consumption of compressed air and increase the speed of operation of the lift. This goal is achieved by the fact that the insert is made of an elastic material, with its dimensions and shape corresponding to the contour B of the 1-sided side surface of the sleeve in its initial position. FIG. 1 depicts a pneumatic elevator in its original position, a cross section in FIG. 2; a section A-A in FIG. I; Fig, 3 - air lift in the working position, the cross-section. A pneumatic elevator consists of an elastic airtight sleeve 1 lying on support 2, in which there is an elastic insert 3 with a longitudinal groove 4 and a through hole S. Opera 2 has an air inlet fitting 6 that enters hole 5, Sleeve 1 interacts with the movable frame 7 (carrying the necessary equipment, such as rollers. The ends of the sleeve are sealed with a seal 8. The pneumatic lift operates in the following manner. Compressed air through the air inlet pipe 6 and the hole 5 enters the longitudinal groove 4 3. Sleeve 1, filled with compressed air, increases in height by moving the frame 7, and at the same time shortens in width, bending upwards the edge of the elastic insert 1–3 of the insert 3, due to the fact that in the initial position of sleeve 1 there are no lateral cavities. the sleeve, as is the case in the well-known pneumatic lift, the required amount of compressed air required to fill the inner cavity of the sleeve 1 is reduced by an amount equal to the volume of these cavities and, accordingly, the speed of the pneumatic lift increases. Increasing the total volume by increasing its width, and, accordingly, reducing the compressed air supplied to the hose for lifts with a hose stroke that is 2.6 to 3 times its original Height, is 37-42% of the corresponding parameters of the known pneumatic lift. , and 15–20% for lifts with a sleeve stroke, 1.7–2 times the height of the initial height, i.e., the greater the difference between the longest stroke and the initial position of the sleeve, the more effective the efficiency and pnevodomodnika performance increase in the volume of el cal aa insertion score (icheni its width
