With the rapid development of urbanization, the disposal of urban waste has become increasingly a problem. As an emerging waste treatment technology, waste incineration power generation has received widespread attention and application. Waste incineration power generation converts waste into electricity through high-temperature combustion, which not only solves the problem of waste disposal, but also provides renewable green energy to society.

When you choose Dongqi Crane to equip and service your waste-to-energy-and-biomass facilities, you acquire a trusted source of global experience and knowledge, combined with local know-how to empower your lifting operations and increase your safety and productivity. We offer cranes, features and services designed to serve renewable energy production needs.

Turning waste or biofuel into energy is a complex process. Many of our engineers have extensive experience in waste and biomass handling so they understand the demands of reliable lifting technology.

Crane Equipment for Waste to Energy and Biomass industry

Overhead crane with grab: A grab crane plays a crucial role in modern incineration plants, where tight environmental guidelines apply and material handling must perform at maximum efficiency from the moment waste arrives, as the crane stacks, sorts, mixes and delivers it to the incinerator. Typically, there are two grab cranes above the waste pit, one of which is a backup, to ensure minimal downtime.

Straw bale handling cranes: A straw bale handling crane is designed to handle bales of hay at a power plant that uses straw as a fuel source. These cranes unload the bales from delivery trucks, move them into storage, and feed them into processing. Bales are usually rectangular and relatively dry, which makes them easier to handle. You should choose a straw bale crane based on the annual volume of straw pellets you intend to produce, the layout of the plant, your bale storage capacity and frequency of bale delivery.

Dongqi crane waste-to-energy equipment uses the latest in lifting technology to help you move your loads safely and efficiently in any working environment. Our long history has given us the experience and know-how to provide the right crane for your facility, backed up with local branches of a global service network to give you the confidence that spare parts and technical assistance are always close.

Current situation of Pakistan’s waste to energy market

Pakistan is the sixth most populous country in the world, with a population of over 230 million. In recent years, with the continuous development of the domestic economy, the acceleration of urbanization process, and the gradual increase in population, the amount of household waste in Pakistan has surged. The annual waste production has basically maintained between 20-30 million tons, and it continues to increase at a rate of over 2% every year, which has seriously affected the living environment and quality of local residents, How to deal with household waste has gradually become a headache for the Pakistani government. In addition, Pakistan is currently facing a serious power shortage problem, which seriously affects the coverage and sustainability of electricity consumption by Pakistani citizens and businesses. The application of garbage power generation technology not only effectively alleviates Pakistan’s garbage disposal problem, but also enhances the country’s power supply capacity to a certain extent, with huge market development potential.

However, Pakistan’s domestic waste to energy technology is relatively backward, and domestic waste to energy projects mainly rely on overseas enterprises for promotion. As a country along China’s “the Belt and Road” policy, the Pakistani market has also received high attention from Chinese enterprises. For example, in April 2022, the Energy Department of Sindh Province in Pakistan signed a letter of intent with five companies, including Khan Renewable Limited, Babcock Wilcox Limited, and China National Machinery Engineering Corporation, planning to establish a separate “waste to energy project” in Jamchakro, Karachi by the end of 2023, which is expected to supply 175-200 megawatts of electricity to the region.

Customer Stories

German wood-fired CHP station uses double-girder bridge crane to handle wood

A wood-fired combined heat and power station in Hamburg-Lohbrügge uses natural wood chips from forestry and landscaping work to generate around 13 million kilowatt-hours of electricity annually from renewable resources. The 60,000 megawatts of heat generated simultaneously are channeled to neighboring district heating plants, supplying more than 8,000 homes. The €13 million investment in the plant will reduce CO2 emissions by 23,000 tonnes per year.

The fuel is moved from the transfer point to the furnace via a crane. The double-girder bridge crane on site has a span of 16.4m, a hoist of 11t, and a lifting height of 24.5m. An 8 cubic meter multi-claw grab was installed. It is fully automated and the technology plays a key role in the energy production process.

One of the crane’s tasks is to control the motor-driven multi-claw grab. This grapple is designed for handling lumber as the material arrives at the mill in its natural and varied state. The unit reliably picks up loads ranging from fine shredded wood to small branches and compacted materials. About 32,000 tons of wood chips are supplied by truck each year. A minimum of 140 cubic meters of material must be processed per hour.

Application of 3-ton mobile gantry crane in Pakistan’s waste degradation equipment production workshop

Mobile gantry crane is a kind of light trackless gantry crane. Since it can move away from the limitation of the track, it is more convenient to use in many workshops. The case we want to share today is a case of a mobile gantry crane from Karachi, Pakistan. The customer customized a 3 ton mobile gantry crane for the production workshop of waste treatment equipment. The lifting equipment will provide customers with a stable and reliable lifting experience for effectively lifting equipment motors, external casings, etc.

Main parameters of Pakistan mobile gantry crane

• Lifting weight: 3 tons
• Lifting height: 2.8 meters
• Span: 4.4 meters
• Voltage: 380/50/3

The customer added a gantry crane due to the production needs of the new workshop. Considering the weight of 3t, our technical engineer suggested that the customer use an electric trackless walking gantry crane, which does not require the installation of fixed guide rails on the ground, and can also reduce the hidden dangers caused by manual implementation. . Equipped with a wireless remote control device, it can lift heavy objects in the area, and when the mobile gantry walks to the designated location, it can be smoothly loaded and unloaded.
