Dongqi Crane serves the power industry with material handling equipment for every type of power plant. From a traditional coal power plant to a massive hydro power plant or a remote wind farm, we have the cranes and service to suit your needs.

Equipment for Power Industry

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.

Customer Reference Stories

Hydroelectric power station in Thailand

The Naresuan Dam was built between 1976 and 1985 to control the flow of the Nan River north of the city of Phitsaulok in Thailand. As part of its strategy to increase clean power generation, the Thai government is building a new 8.4MW hydropower plant at the site.

Dongqi crane was contracted to supply and install the powerhouse crane for the plant. We has installed similar lifting equipment for several power plants, both for government infrastructure and private sector industrial units.

The main duty of the crane is to service the turbine. Safety, reliability and high accuracy movement are primary requirements. The electric wire rope hoist installed at the site has a lifting capacity of 60/12.5t and an 11m span. A very high lifting height of 33m was needed, since the turbine rotor is positioned that far below the level of the crane, and a customised drum length was fitted to reach that demanding height. Removing and re-installing the rotor for maintenance necessitates that it be lifted smoothly to ground level in a single operation. A true vertical lift design was also necessary to keep the hook positioned centrally to ensure accuracy of lift.

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.
