Large steel structure sliding installation technology

Computer-controlled lifting and hoisting technology is an advanced method used for installing steel structures and large equipment. This technique integrates mechanical systems, hydraulics, computer control, and sensor monitoring to overcome challenges that traditional lifting methods struggle with—such as height limitations, weight capacity, structural alignment, and site constraints. The process is safe, reliable, and technologically mature, offering significant economic benefits. It operates on the principle of "flexible steel cable load-bearing" combined with hydraulic cylinder clusters and computer-controlled synchronized lifting, ensuring precise coordination across all lifting points. Key technical specifications require careful consideration of both permanent and temporary load-bearing structures, as well as the strength, stiffness, and stability of the structure or equipment being lifted. Mechanical performance under construction conditions must be analyzed, and forces at each lifting point should be calculated. The support system and foundation must also be checked for sufficient bearing capacity and overall stability, especially under unfavorable conditions. Synchronization between lifting points must be carefully calculated to ensure smooth operations. The selection of the lifting method aims to minimize the height of the load-bearing structure while maintaining its stability. Safety and stability during the lifting process are prioritized. Lifting points are determined based on the need to ensure structural stability, reduce their number where possible, and enhance the equipment’s carrying capacity to meet design standards. Lifting equipment should be efficient, durable, easy to maintain, and capable of meeting specific project requirements like mobility, speed, and safety features. The slip method is highly adaptable. It can be applied not only to one-way trusses but also to two-way trusses or grids with limited rigidity by adjusting support points, increasing the platform width, or assembling multiple trusses simultaneously. The propulsion system used in this method can be a computer-controlled hydraulic crawler, offering high automation, ease of use, strong safety, and versatility. Main technical measures include preparing a detailed construction plan, erecting high-altitude assembly platforms, setting up slide tracks, installing synchronous sliding systems, and implementing stress and strain monitoring to ensure controlled construction. This technology is widely applicable in projects such as large-span roofs, stadiums, theaters, hangars, and steel flyovers, provided there are suitable ground assembly conditions and stable surrounding support. It is also used for lifting ultra-high components like TV tower antennas and power station boilers, as well as large equipment such as main girders and boilers of heavy cranes. Notable applications include the National Library's main library steel structure (10,800 tons), the A380 aircraft maintenance warehouse roof at Capital International Airport (10,500 tons), Shenzhen Civic Center's large roof, Guangzhou New TV Tower, the installation of a 130mm × 4200mm CNC hydraulic coil machine at Dongfang Boiler Factory, and the overall upgrade of an 800t × 185m gantry crane (4,750 tons) at Offshore Oil Engineering (Qingdao).

Solenoid Armature Tube OD 13mm

BRANDO is a Solenoid Valve Armature Plunger manufacturer and exporter in Ningbo, China, which has more than 10 years experience.

The armature assembly or anchor system is the very important component of Solenoid Valve. An internal stainless steel plunger moves up and down to seal on the top and bottom valve seats. Brando provides armatures in multiple sizes depending on the application's flow requirement. Four common pneumatic functions are available which include:

1. 2/2 normally closed(NC),
2. 3/2 normally closed(NC),
3. 2/2 normally open(NO),
4. 3/2 normally open(NO).

The seals in the plunger are NBR (standard), but FKM, HNBR, PTFE, EPDM are available for different media and temperatures. Most of our armatures are designed to accept AC and DC voltages. Some armatures are DC only for low watt applications.

Brando offers flexibility as the connection to the seat cavity can be with a thread/o-ring seal style or o-ring flange style that requires a mounting plate.
