The place of power industry in Pakistan

The power industry is a crucial component of Pakistan’s economy, as it provides the necessary energy for the country’s industrial, commercial, and domestic needs. The power industry in Pakistan is made up of both thermal and renewable energy sources, with coal, natural gas, and hydropower being the main sources of electricity generation.

Coal-fired power plants are the most common type of power generation in Pakistan, accounting for about 40% of the country’s total installed capacity. Natural gas-fired power plants also play a significant role in meeting the country’s energy needs. In addition, Pakistan has a large hydropower potential, and hydropower plants account for about 20% of the country’s total installed capacity.

The power industry in Pakistan faces several challenges. One of the main challenges is the lack of a stable and reliable supply of electricity. Frequent power outages are common in many parts of the country, and load shedding (scheduled power cuts) is a regular occurrence. The lack of a reliable power supply has a negative impact on the country’s economic development and affects businesses and households.

Another challenge facing the power industry in Pakistan is the high cost of electricity. The cost of electricity is higher in Pakistan compared to many other countries, and this makes it difficult for businesses and consumers to afford it. In addition, power plants in Pakistan are often outdated and inefficient, leading to higher production costs and increased emissions of greenhouse gases.

In order to address these challenges, the government of Pakistan has been taking measures to improve the power sector. One of the key strategies is to increase the use of renewable energy sources such as solar and wind power. The government has set a target of increasing the share of renewable energy in the country’s energy mix to 60% by 2030. In addition, the government is also working to improve the efficiency and reliability of the power grid, including through the construction of new transmission lines and substations.

Crane Equipment for Power Industry

Crane equipment is an important part of the power industry, used for the transportation and handling of heavy loads. In the power industry, cranes are used for the construction, maintenance, and decommissioning of power plants, as well as for the handling of fuel, water, and other materials required for power generation.

Different types of cranes are used in the power industry depending on the specific needs of the application. Mobile cranes are often used for the transportation and positioning of heavy components such as turbines and generators. Fixed cranes are installed at specific locations to handle regular material handling tasks. In addition, specialized cranes such as overhead cranes and gantry cranes are used for specific applications.

When selecting crane equipment for the power industry, several factors need to be considered. The capacity of the crane, which depends on the weight and size of the loads to be lifted, is a key consideration. The type of crane (mobile, fixed, or specialized) and its features should be chosen based on the specific needs of the application. The location and layout of the power plant also influence the choice of crane equipment.

In addition to the choice of crane equipment, it is also important to consider safety and environmental factors. Safety measures such as fall protection and load stabilization should be implemented to prevent accidents. Environmental factors such as noise and emissions should also be taken into account when selecting crane equipment to ensure it complies with local regulations and has minimal impact on the environment.

• Overhead Crane: Depending on the items being lifted, the power industry needs to choose different bridge cranes. If you don’t know how to choose, you can tell us the working conditions in detail, and our engineers will design the bridge crane that best suits your usage. Bridge cranes can lift and transport heavy objects, such as large boilers, generator sets, pipes, valves, etc., in power plant buildings, warehouses, docks and other places. These devices are often very heavy and require the assistance of a crane to move and install.
• Workstation Crane: The advantages of workstation cranes are mainly reflected in improving work efficiency, enhancing safety, saving human resources, being highly adaptable, improving hoisting accuracy and improving the working environment. These advantages make workstation cranes widely used in industrial fields such as power plants. Workstation cranes also have the characteristics of compact structure, small footprint, and easy operation, making them one of the indispensable equipment in power plants.

Quebec Waste Plant, Canada

Quebec city processes 280,000t of waste each year. The waste is burned and converted to steam for consumption by local clients in a combined heat and power plant. Equipment in the plant was reaching the end of its service life.

Quebec city needed to modernise the system without interrupting its round-theclock operation.

The cranes on the site had been installed in 1974, and were outdated, in particular their energy consumption was by today’s standards excessive— “astronomical” in the words of senior engineer Yves Fréchet. Nor were they reliable: despite weekly maintenance, interventions had to be carried out on them almost daily. During those times the furnaces could not be fed, causing considerable disruption and costs.

They were replaced with higher capacity Dongqi Crane units with new controls and power systems and full automation.

To install the new cranes while the old ones were still operating, a temporary ‘parking area’ for the new cranes was built from which they could be rolled straight into position. There was tight co-ordination so that as soon as the cranes were on the trackway they were already ready to be used. There was no lag time between installing the cranes and operating them, and there were no intrruptions to daily operation.

The installation resulted in a 12% saving in energy. Precision has been increased, down to centimetre accuracy. Inspections are carried out once a week, but that is all that is needed. The old cranes cost up to C$400,000 a year to keep in service; costs are now down to C$100,000.
