The Low Clearance Overhead Crane for Power Station is specially designed for power plants, turbine halls, boiler rooms, and equipment maintenance areas. Its low-headroom structure maximizes effective lifting height in workshops with limited building height. Equipped with a main hook and an auxiliary hook, the crane is suitable for installation, maintenance, and repair of generators, turbines, boiler auxiliary equipment, pumps, valves, and other large components. It features stable operation, compact structure, and high space utilization, with span, lifting height, speed, and control system customizable according to power plant requirements.
Product Features：
1. Low Clearance Design for Higher Effective Lifting Height
The crane adopts a low-headroom structure to reduce the space occupied by the bridge and hoisting mechanism, maximizing effective lifting height in power plant workshops with limited headroom.
2. Designed for Power Plant Maintenance
It is suitable for turbine halls, boiler rooms, main equipment maintenance areas, and power plant service zones. It can be used for lifting and maintaining generators, turbines, pumps, valves, boiler auxiliary equipment, and other large components.
3. Main Hook and Auxiliary Hook Configuration
According to the drawing, the crane is equipped with both a main hook and an auxiliary hook. The main hook is used for heavy equipment lifting, while the auxiliary hook supports positioning, adjustment, and maintenance operations.
4. Smooth Operation for Precision Handling
The low-speed main hoisting system is suitable for power plant maintenance tasks that require stable lifting and accurate positioning.
5. Cabin Control with Better Visibility
The operator cabin is installed under the bridge structure, allowing operators to observe the working area more directly and improve lifting safety.
6. Multiple Span Options
The drawing shows span options from 10.5m to 31.5m, allowing the crane to adapt to different power plant layouts and workshop widths.
7. Customizable for Power Plant Conditions
Lifting capacity, span, lifting height, travelling speed, electrical control system, cabin position, and safety protection devices can be customized according to actual power plant requirements.

The Low Clearance Overhead Crane for Power Station is a bridge crane specially designed for power plants, power stations, turbine halls, boiler rooms, and equipment maintenance areas. With a low-headroom structure, this crane maximizes effective lifting height in workshops with limited building height and reduces overhead space occupation.
The crane generally consists of bridge girders, crane travelling mechanism, trolley travelling mechanism, hoisting mechanism, operator cabin, electrical control system, and safety protection devices. According to the technical drawing, the crane is equipped with a main hook and an auxiliary hook, making it suitable for both heavy equipment lifting and auxiliary handling operations. The operator cabin is arranged under the bridge structure, providing a better view of the lifting area for maintenance and precision handling.
Compared with ordinary overhead cranes, the low clearance overhead crane features a more compact structure, smaller hook upper limit, and better space utilization. It is suitable for power plant equipment maintenance, generator unit servicing, turbine component handling, boiler auxiliary equipment maintenance, pump and valve replacement, and large mechanical component lifting.
