In the construction and maintenance of hydropower stations, heavy lifting and handling are often involved. At this time, workers use tools such as chain hoists, lifting belts, and shackles for lifting operations.
Hydroelectric power plants are often located in mountainous or remote areas with inconvenient transportation, and the transportation and deployment of large mechanical equipment face many difficulties. Hand pulled haws are compact in size and lightweight, making them easy to carry to every corner of the construction site. For example, in the construction of small hydropower stations located in deep mountain canyons, chain hoists can be manually transported to narrow construction areas, such as underground powerhouses or tunnels. In these areas where large lifting equipment is difficult to access, chain hoists can be quickly put into use, providing convenience for construction.
Hand pulled hoists do not require complex electric or fuel drive systems, and can lift heavy objects by simply pulling the chain manually. This gives it an irreplaceable advantage in some special situations. For example, during the power outage maintenance period of a hydropower station, when other electric lifting equipment cannot operate, the chain hoist can still work normally to ensure that critical maintenance tasks are not affected. Moreover, the chain hoist can adjust the lifting height and position at any time according to actual needs. When lifting equipment with irregular shapes or difficult to determine the center of gravity, operators can accurately control the posture of the equipment through manual adjustment, avoiding damage caused by equipment shaking or deviation.
Compared to large cranes or other electric lifting equipment, the procurement cost of chain hoists is lower and maintenance is relatively simple. It does not have a complex electrical control system or a large mechanical structure, and only requires regular inspection and lubrication of key components such as chains, hooks, and braking devices to maintain good working condition. In the long-term operation of hydropower stations, the low maintenance cost and high reliability of chain hoists can save enterprises a lot of capital and manpower investment, making them a cost-effective lifting tool.
