Manual Overhead Cranes Application
Turbine Installation in Small Hydropower Station Construction
When constructing small hydropower stations in remote mountainous areas, limited power supply at the construction site often makes it difficult to use conventional electric lifting equipment. Manual bridge cranes, which do not rely on an external power source, become the ideal choice for turbine unit installation. They enable precise positioning and installation of key components such as the main shaft and runner within the limited space of the powerhouse, ensuring the quality of equipment installation while effectively reducing construction costs.
Transfer of Liquid Chemical Storage Tanks in Chemical Plants
Manual bridge cranes are well-suited for chemical plant environments where flammable, explosive, or corrosive gases may be present. With manual operation and slow hand-pulled movement, they eliminate the risk of electrical sparks and help ensure safe working conditions. During the transfer of liquid chemical storage tanks, the crane’s smooth operation and slow movement help prevent liquid sloshing or leakage, ensuring precise alignment between the tank and pipeline connections. This makes manual overhead cranes particularly ideal for the handling and relocation of small to medium-sized tanks.
Installation and Maintenance of Circulating Water Pumps in Power Plants
The manual overhead crane operates manually, with slow speed and smooth motion, allowing for excellent control over the lifting process. This makes it ideal for the installation and maintenance of equipment such as water pumps. The manual operation also provides high positioning accuracy, ensuring that equipment is aligned more precisely during installation. This minimizes displacement and reduces the need for adjustments, ultimately improving the efficiency and quality of both installation and maintenance work.
