Shutdown and maintenance of gas turbine power plants is a crucial step in ensuring the long-term stable operation of equipment. During this period, heavy components such as valves and heat exchanger modules need to be disassembled, inspected, and reset, making the operation difficult and requiring extremely high safety standards. Guanhang screw jack, with its unique structural advantages and safety performance, has become an indispensable auxiliary equipment for maintenance sites, providing efficient support for maintenance work.

There may be residual flammable and explosive gases in some maintenance areas of the gas turbine power plant, and traditional electric lifting equipment has potential electric spark hazards, which can easily cause safety accidents. The screw jack adopts manual driving mode, without relying on external power sources such as electricity and hydraulic oil, fundamentally eliminating the possibility of electric sparks and perfectly adapting to the special safety environment of the factory area. Its safety far exceeds that of electric and hydraulic lifting equipment.

In actual maintenance operations, components such as valves and heat exchanger modules are heavy and densely installed, making it difficult for conventional lifting tools to operate accurately and prone to equipment damage. The Guanhang spiral jack relies on a precise spiral transmission structure, with smooth lifting and precise positioning. It can not only lift heavy components smoothly, but also free up sufficient operating space for maintenance personnel by adjusting the height, making it easy to carry out operations such as component disassembly, cleaning, and maintenance. Its compact structure and small size can flexibly adapt to narrow spaces on maintenance sites, greatly improving operational convenience. In addition, the screw jack has reliable mechanical self-locking performance, which can stably maintain the load position after lifting, effectively preventing components from accidentally slipping and further ensuring the safety of maintenance personnel and equipment.
