Applications of overhead cranes and gantry cranes in hydropower and wind power projects

In hydropower and wind power projects, bridge cranes and gantry cranes play important roles. Bridge cranes are the mainstay for indoor precision installation and long-term operation and maintenance, while gantry cranes are experts in the handling and assembly of heavy outdoor components in hydropower and wind power projects.
Weihua Group provides integrated solutions for hydropower and wind power bridge gantry cranes – offering greater stability for larger tonnage, greater precision for larger spans, more accurate intelligent control, and greater durability in extreme environments.

1. overhead cranes and gantry cranes for Hydropower Projects

overhead cranes/Bridge Cranes are primarily used inside hydropower plant buildings, for example:

Powerhouse Bridge Cranes: for unit installation, inspection, and maintenance.
Main Powerhouse Bridge Cranes: for hoisting large equipment such as turbines and generator rotors.
Installation Barrier Bridge Cranes: for equipment assembly and maintenance.

gantry cranes are primarily used outdoors or in dam areas, for example:

Dam Top gantry cranes
Intake gantry cranes
Tailrace gantry cranes
Floodgate Opening and Closing gantry cranes
For hoisting and operating gates, trash racks, and other equipment.

overhead cranes and gantry cranes for Hydropower Projects Features:

High Precision and Reliability: Requires millimeter-level precision hoisting within confined spaces. For example, a 170-ton bridge crane purchased by a Norwegian hydropower station was used for hoisting the heaviest single generator rotor in the underground powerhouse; a 1000-ton bridge crane at another hydropower station achieved "millimeter-level precision control."
Large Tonnage and Small Span: Lifting capacity can reach 80-500 tons, but the span is usually small (8-16 meters) to adapt to the factory structure.

2. overhead cranes and gantry cranes for Wind Power Projects

Bridge cranes are mainly used for wind power equipment manufacturing and maintenance:

Wind turbine nacelle production workshop
Generator and gearbox assembly
Wind turbine component overhaul
Wind turbine assembly plant

gantry cranes are mainly used for:

Wind turbine tower production/storage
Lifting of large components such as wind turbine blades and towers
Wind farm equipment installation
Transfer of large wind power equipment at ports or construction sites

overhead cranes and gantry cranes for Wind Power Projects Features:

Ultra-large Tonnage and Flexibility: To meet the trend of large-capacity offshore wind power, the demand for ultra-large tonnage cranes has increased dramatically. Weihua's gantry cranes with a lifting capacity of up to 3800 tons are used in offshore wind power projects.
Large Span and Complex Working Conditions: Equipment often needs to operate in open-air, windy environments, requiring high span and safety margins for the crane.
