As the global demand for stable, clean, and sustainable energy continues to surge, hydropower has once again solidified its role as a cornerstone in the world’s energy landscape. Beyond its contribution to renewable electricity generation, hydropower stands as a symbol of large-scale engineering, integrating innovation, safety, and long-term reliability.
However, hidden beneath the imposing concrete walls of dams and the immense turbines that drive electricity generation are some of the most formidable engineering challenges in existence—particularly in the precise lifting, installation, and maintenance of super-heavy components such as stators, rotors, and gate structures. These operations demand not only raw lifting power but also absolute precision, operational safety, and uninterrupted reliability, as any delay or error can jeopardize the entire plant’s performance.
In this demanding environment, TXLET has established itself as a global leader and trusted partner in hydropower lifting technology. By delivering advanced Overhead Cranes, Gantry Cranes, and Specialized Hoist Systems specifically engineered for the harshest hydropower conditions, TXLET ensures seamless project execution, exceptional durability, and 100% operational reliability. From Asia to Europe, TXLET crane solutions have played a decisive role in powering sustainable growth and securing the future of global energy infrastructure.
Hydropower is not only a clean source of electricity but also a dispatchable and highly reliable power supply, playing a crucial role in balancing energy grids. Unlike solar and wind, which depend heavily on weather conditions, hydropower plants can generate electricity on demand, making them a stabilizing backbone for national energy security. For countries aiming to expand renewable energy while ensuring grid stability, hydropower remains a strategic pillar that guarantees both sustainability and reliability.
The scale of hydropower projects is truly monumental. A single dam integrates thousands of critical components, from massive turbines to gate valves and auxiliary systems, all of which must work flawlessly together. At the heart of the powerhouse, core structures such as Rotors, Stators, turbine runners, and dam gates often weigh anywhere from 50 tons to more than 500 tons each. Their installation, alignment, and maintenance are not only engineering feats but also constant battles against gravity, where any margin of error can lead to operational inefficiency or costly downtime. This is where TXLET’s specialized crane and hoist solutions act as the golden key—delivering not just brute lifting force but also the micrometer-level precision, reliability, and safety required for hydropower success.
Among the toughest challenges inside a hydropower station lies the restricted working environment of the turbine hall. Enclosed within reinforced concrete structures, engineers must install and service gigantic machinery within a space that often allows very little tolerance. This makes maximum hook coverage (minimum hook approach) and effective lifting height (maximum lift height) essential design requirements for cranes operating in these environments.
In addition, setting a Rotor—the centerpiece of the generator—demands conditions that go far beyond conventional lifting. The process requires perfect balance, ultra-slow movement, and absolute stability, since even the smallest vibration or deviation could cause long-term misalignment and reduce turbine efficiency. For this reason, traditional industrial cranes simply cannot meet the stringent technical demands of hydropower projects. Instead, purpose-built systems—like those engineered by TXLET—are required to combine heavy-lift capability with high precision control technologies such as inverter-driven variable speeds and advanced load monitoring systems.
By conquering these dual challenges—immense weight and confined space—TXLET ensures that every lift is executed with the reliability and safety standards that hydropower plants cannot operate without.
Inside the powerhouse, the Overhead Crane supplied by TXLET is regarded as the most vital equipment, accompanying the generating unit throughout its entire lifecycle—from the very first installation to decades of operation and periodic maintenance. It is no exaggeration to say that the success or failure of a hydropower project depends heavily on the reliability of this crane system.
Turbine Unit Installation: The installation of the Stator and Rotor is considered the most critical and challenging stage. TXLET applies a Dual Synchronized Hoist System, in which two independent trolleys operate in perfect harmony. Controlled by advanced PLC logic and high-resolution Encoders, the system ensures the load remains balanced with a positional error margin of only 1–2 mm, even across lifting paths stretching tens of meters. This degree of accuracy is necessary to guard against misalignment, minimize installation mistakes, and ensure the turbine's long-term functioning.
Disassembly and Maintenance: Beyond installation, the Overhead Crane also plays a decisive role in disassembly. Components such as turbine shafts, guide vanes, or bearings must be removed for inspection against erosion and cavitation. These operations require both speed and accuracy, particularly during scheduled shutdowns where time pressure is critical. Designed for heavy-duty cycles (FEM 2M/3M), TXLET cranes are built to handle these demanding tasks with efficiency and reliability, even under continuous operation.
TXLET does not merely provide lifting equipment—it delivers measurable value to project owners.

While the Overhead Crane works within the powerhouse, the Gantry Crane guards the dam crest like a steel fortress, operating under extreme environmental stress. Constant exposure to high humidity, acid rain, saltwater mist, and intense UV radiation requires equipment that combines heavy lifting strength with extraordinary resistance to corrosion and weathering.
Hydraulic Gate Lifting: TXLET Gantry Cranes are engineered to safely lift and lower massive spillway or intake gates, with typical lifting capacities ranging from 100 tons to 300 tons. Their robust design allows them to withstand strong winds and fluctuating water pressure during critical operations.
Optimized Ultra-Slow Lifting Velocity: Unlike industrial cranes that prioritize speed, hydropower gantry cranes must move at ultra-slow velocities (typically 0.3–0.6 m/min). This ensures smooth and controlled gate movements, minimizing the risk of water hammer effects that could otherwise damage pipelines, valves, or dam structures.
Specialized Debris Removal: In addition to gate lifting, gantry cranes can connect to auxiliary equipment such as large Grabbing Buckets. This capability is essential for clearing debris and maintaining uninterrupted water intake—an often-overlooked yet critical aspect of dam operation.
TXLET incorporates military-grade protection systems to guarantee long-term durability.
Zinc/Epoxy Coating: The steel structure—typically high-strength alloy steel—undergoes Hot-Dip Galvanizing (HDG) to ISO 1461 standards, followed by a three-layer Epoxy/Polyurethane coating. With a total Dry Film Thickness exceeding 400 microns, this ensures robust resistance to C5-M environmental conditions characterized by high humidity and constant water exposure.
Electrical & Cable Protection: Electrical cabinets and motors are designed to IP65 standards, providing total protection against dust and high-pressure water jets. Cables are UV-resistant, high-flex types that can endure continuous bending and harsh sunlight without degradation.
Where large cranes may be excessive, Hoist Systems offers compact, cost-effective, and automated solutions for operating smaller gate valves and auxiliary discharge gates. Despite their smaller size, these hoists are engineered for durability, safety, and seamless integration into modern plant automation systems.
Fixed Winch Hoist: Designed for simplicity yet built for endurance, these hoists feature heavy-duty gearboxes, anti-twist steel ropes, and rugged construction, enabling decades of reliable operation even under harsh, wet environments.
SCADA/PLC Integration: TXLET’s hoists can be fully integrated into SCADA or PLC systems, allowing operators to automate gate movements according to predefined scenarios. For instance, gates can automatically open when water reaches a critical threshold, greatly enhancing flood control capabilities and plant safety.
By combining Overhead Cranes, Gantry Cranes, and Hoist Systems into one comprehensive package, TXLET delivers a full spectrum of hydropower lifting solutions—each tailored to its specific environment and role, yet all built upon the same foundation of precision, reliability, and long-term performance.

Maximized Availability: With the EHM system, crane availability is maintained above 98%. Every hour of downtime for a major hydropower unit can result in tens of thousands of dollars in lost revenue. Ensuring the crane is quickly operational during maintenance directly maximizes plant profitability.
Longevity: Strict adherence to FEM/ISO duty cycles and anti-corrosion solutions allows equipment lifespans to exceed 40 years, reducing long-term capital expenditure (CAPEX).
To guarantee that equipment can handle super-heavy loads and operate safely, TXLET implements a multi-level QA/QC process:
Material Inspection: All structural steel (typically high-strength alloy steel) is checked using Spectrometry analysis and Ultrasonic Testing (UT) to ensure zero internal defects.
Welding Inspection: Critical load-bearing welds are inspected using Magnetic Particle Testing (MT) and Penetrant Testing (PT), particularly at the intersection points of the main girder and crane legs.
Load Testing: Every crane must undergo static load testing (typically 125% SWL) and dynamic load testing (typically 110% SWL) before leaving the factory, witnessed and certified by independent inspection bodies (e.g., SGS, Bureau Veritas).
Final Certification: Complete technical documentation, including drawings, material certificates, inspection reports, and load test certificates, is provided as a detailed "Equipment Passport," ensuring compliance with all international and local regulations.
