Don't understand what you mean?

The pier fence and the hanging basket are the bridge hanging baskets. And the technical requirements of the bridge gondola.

1. The connection between the steel components is welded, and the weld height is 6mm.

2. Q235 steel for steel; The steel bar is HPB type, and the hooks are all standard hooks, which need to meet the design requirements. 3. The anti-corrosion of all exposed steel structures is carried out by the first coating system in the "Railway Steel Bridge Protection Coating", that is, 2 coats of special red danphenolic anti-rust primer, 2 coats of gray aluminum powder graphite or gray cloud ferryl alkyd topcoat; The components must be derusted before the primer is applied, and at the same time, the painting should be carried out in sunny weather, and no work should be carried out in the morning and night.

4. Before the anti-corrosion treatment, the welding ballast must be removed to a clean surface, and then applied in accordance with the anti-corrosion coating procedure. 5. The gap between the step plates is filled with dry hard cement mortar.

6. The connection of the bracket and the handrail is firmly connected by double nut and single nut respectively; The hollow pier is blocked with dry hard cement mortar in the exposed part of the embedded channel.

7. Each side of the pier top fence is provided with a chain that can be opened, and it is fastened when there is no personnel entering and exiting.

8. Reinforced concrete step plate centralized prefabricated vibration molding, loading and unloading, transportation and installation process, should be handled gently, stacking height shall not exceed 3 layers, shall not collide to cause damage to edges and corners. "Jinlida" professional custom bridge hanging basket.

Summary. Hello dear! There is no fixed limit to the lifting height of the bridge support hanger, but it can usually reach a maximum of about 50 meters, and there is a risk if it exceeds this range.

Hello dear! There is no fixed limit on the hoisting height of the bridge support crane, but it can usually reach a maximum of about 50 meters of closed fire, and there will be risks if it exceeds this range.

Precautions should be taken when installing the bridge 1. When the appearance inspection is transported to the construction site of the bridge, it is necessary to submit the factory certificate of the product, the provincial and municipal quality supervision report, as well as some relevant information such as technical appraisal documents. 2. When the installation position of the bridge is laid horizontally, the height can not be lower than that, in order to dissipate heat and maintain some needs, remember to leave reserved space before the key is accepted when laying in multiple layers, and the net distance should be in line with the relevant regulations. 3. The quality of the support and hanger installed in the bridge should be laid horizontally in accordance with the relevant technical standards, the support of the span is the vertical laying, the fixed spacing can not be more than 2m, the horizontal height difference between the two adjacent bridge supports can not be 10mm, and the vertical centerline deviation cannot be greater than 20mm.

Kiss! Hello, happy to answer your <>

When the pro-bridge support hanger exceeds how many meters can not be hoisted into the house from the outside, the slope of the bridge to the outside can not be less than one percent. When it intersects with electrical equipment, the net distance in the middle cannot be lower than which meter of the wheel. Then when the two groups of bridges are installed in parallel at a uniform height, the net distance in the middle is not less than 0.6 meters.

The bridge is more than two meters above the ground, and the top surface cannot be less than one meter from the roof or other obstacles. Extended Information:1.

The cable tray bracket should be made according to the requirements of the drawings and the site conditions; When installing, the pull-through line should be pulled to control the horizontal and verticality; 2。The bracket spacing of the horizontal installation of the cable tray is, 2m; It is known that the spacing of the bracket installed vertically is not more than 2m; Fixed brackets should be set at horizontal lengths of more than 20 meters or at turns and corners; 3。When the top burst screw process is used, the drill bit selection should be matched with the top burst screw, and then the double nut lock is on the wire screw, and the wrench is firmly connected with the top burst screw.
