The development trend of climbing frame electric hoist is more and more fierce. There is a tendency to surpass the sales volume of electric chain hoist. Why is climbing frame electric hoist so hot? Why is it loved by market customers? Let's analyze it for you from the structural aspect: (1) At present, the lifting equipment of the overall climbing external scaffolding is basically an electric hoist, and the entire external scaffolding climbs up along the building outer wall or column as a whole. The height is set according to the height of the standard floor of the building, and most of them are taken from the height of the four floors of the standard floor of the building plus the height of the one-step guardrail as the total height of the frame. (2) If you want to use conventional steel tube fastener scaffolding, you can use double-row scaffolding or bowl-type socket-type scaffolding. The installation requirements are the same as those of conventional scaffolding, and the requirements are also the same. (3) The next step of the frame body is the bearing frame of the whole frame body, because the bearing frame is often still a part of the whole frame body, so there are inclined web rods in each internode, and the upper chord, diagonal Both ends of the abdominal rods adopt double-tube load-bearing analysis frame and are located on the load-bearing support made of section steel, and the Φ25 flower bar screw is used to transmit the force of the load-bearing support to the main structure. (4) Hydraulic climbing mold Composition: The outer formwork system is composed of a steel analysis frame, a three-layer working platform, an outer formwork, supporting corbels and jacks, etc. The inner formwork system. The inner formwork system consists of a bin rack, an inner formwork, a two-layer workbench, jacks, corbels, etc. Composition. Hydraulic lifting system. The hydraulic lifting system consists of a lifting console, oil lines, jacks, etc. Jacks for the outer mold lifting are arranged on the outer wall, and jacks for the inner mold lifting are arranged on the inner grid steel beam. Oil system. Outer mold Self-contained system with the inner mold, each lifting "there are high-pressure oil pumps, switches, leveling cups and other devices in the operation platform" (5) When the outer mold climbs, it is lifted up by the jack supported on the concrete wall. The template is left when climbing Concrete wall 200-300mm, no friction resistance" After climbing to the elevation, the corbel on the outer formwork extends into the reserved hole in the concrete wall to bear the full weight of the outer form, and the jack returns oil away from the concrete surface, the outer form pushes To the wall surface, correct the verticality and start to tie the steel bars, and support the opening mold.
