The equipment has been successfully installed, commissioned and officially put into operation in the Egyptian thermal power plant. It fully meets the plant’s high-standard safety, high-frequency operation and long-term stable working demands, effectively solving the pain points of inefficient hoisting, low safety coefficient and insufficient load capacity of the original old equipment, and providing solid equipment support for the stable operation and capacity expansion of the power plant.

65 Tons Overhead Crane Technical Parameters

The 65-ton double-girder overhead crane is professionally configured to adapt to thermal power plant working conditions. The core technical parameters are standardized and customized to meet international power industry operation standards, with detailed specifications as follows:

Project Challenges

The operating environment and functional requirements of thermal power plants put forward strict and professional challenges for the customized design and operation of overhead cranes, which are mainly reflected in the following aspects:

• ◆ Harsh On-site Operating Conditions: The interior of the thermal power plant is characterized by high temperature, high dust, and occasional corrosive gas erosion. Conventional cranes are prone to aging parts, reduced operating accuracy and frequent failures in such environments, which cannot adapt to long-term continuous operation.
• ◆ High Precision Hoisting Requirements: The core power equipment such as turbine rotors and generators are large in weight, high in precision and fragile in structure. The hoisting process requires extremely high positioning accuracy, and slight deviation may cause equipment damage and huge economic losses.
• ◆ Strict Safety and Stability Standards: Power plant equipment maintenance and installation operations are high-risk links. The crane must have ultra-high structural stability, reliable braking performance and perfect safety protection devices to avoid safety accidents such as load slipping and structural shaking.
• ◆ Adaptation to Local Specifications: The equipment needs to comply with Egyptian industrial safety standards and international power plant equipment operation specifications, and adapt to the on-site plant span, lifting height and electrical supporting conditions of the project.

Customized Crane Design & Technical Advantages

Combined with the actual working conditions of the Egyptian thermal power plant and the above challenges, our R&D and engineering team carried out targeted customized optimization for the 65-ton overhead crane, focusing on improving environmental adaptability, operation precision, safety performance and service life. The core design and technical advantages are as follows:

1. Heavy-Duty Double-Girder Structural Design

The crane adopts an integral double-girder box-type structure, which is optimized through finite element stress analysis. The main girder is made of high-strength low-alloy steel, with strong bearing capacity, good rigidity and small deformation. It stably supports the 65-ton rated load and meets the heavy-duty working cycle requirements of power plants. The overall structure is sturdy and durable, effectively resisting structural fatigue caused by long-term high-frequency hoisting, and adapting to the long-duration operation mode of thermal power plants.

2. High Temperature and Dust Resistant Configuration

Aiming at the high-temperature and dusty environment of the power plant, the crane is equipped with dust-proof, heat-insulating and anti-corrosion configurations in an all-round way. The electrical control cabinet, hoist and operating mechanism adopt fully sealed protective structures to prevent dust and hot gas from invading internal parts. The surface of the equipment is sprayed with high-temperature resistant and anti-corrosion paint, which effectively delays equipment aging and ensures stable operation in harsh plant environments for a long time.

3. High-Precision Intelligent Control System

The crane is equipped with a dual control mode of cab operation and wireless remote control, with flexible and convenient operation. It adopts frequency conversion speed regulation technology, which realizes smooth start, stepless speed regulation and stable stop, effectively avoiding equipment swing and position deviation during hoisting. The precise positioning error is controlled within ±5mm, which fully meets the high-precision hoisting and alignment requirements of power generation core equipment such as turbines and generators.

4. Complete Safety Protection Mechanism

In line with the high safety standards of power plant operations, the crane is equipped with a full set of safety protection devices, including overload limit protection, height limit protection, travel limit protection, emergency stop device, brake failure protection and anti-collision system. Once abnormal load, over-travel or equipment failure occurs, the system will automatically cut off the power and lock the operation to ensure the absolute safety of hoisting operations, equipment and on-site personnel.

5. Energy-Saving and Efficient Operation Performance

The optimized transmission mechanism and high-efficiency motor reduce operation energy consumption and mechanical wear. The equipment has low failure rate and convenient daily maintenance, which greatly reduces the later operation and maintenance cost of the power plant, and meets the local energy-saving and environmental protection requirements in Egypt.

Project Implementation Process

The project adhered to standardized and refined whole-process management, from scheme design, factory production, quality inspection to on-site installation, commissioning and training, ensuring the smooth delivery and stable operation of the equipment.

In the early stage of the project, the engineering team conducted on-site investigation on the Egyptian power plant, accurately measured the plant span, lifting height, track foundation and electrical parameters, and combined with the customer’s actual operation scenarios to finalize the customized design scheme, ensuring that the equipment is fully adapted to the on-site working conditions. During the production stage, all core components are processed and manufactured in strict accordance with international industrial standards, and multiple strict quality tests such as load test, no-load operation test and safety performance test are completed before leaving the factory.

After the equipment was delivered to the project site, our professional installation and commissioning team overcame the difficulties of cross-border construction and on-site environment, completed track laying, equipment assembly, electrical wiring and system debugging efficiently and safely. At the same time, we provided professional operation and maintenance training for the power plant’s on-site operators and maintenance personnel, covering equipment operation specifications, daily maintenance points, fault judgment and emergency disposal methods, to ensure that the staff can proficiently use and maintain the equipment.

Finally, the equipment passed the acceptance of the power plant and the local industrial supervision department with excellent performance, and was officially put into formal operation.
