Gantry cranes are widely used in water conservancy projects. First of all, gantry cranes are often used in steel structure construction in water conservancy project construction, such as the hoisting of large sluices, water gates, bridges and other steel structures. It can easily hoist heavy steel plates, steel beams, etc. to designated locations, greatly improving construction efficiency. Secondly, gantry cranes also play an important role in the transportation of water conservancy projects. They can transport sand, gravel, cement, steel bars, concrete and other materials, and can also quickly move large equipment such as excavators and loaders to the construction site, thereby improving transportation efficiency and Construction Schedule. In addition, gantry cranes are also used in special environments of water conservancy projects, such as for strengthening river dams.
The case shared by Dongqi Crane today is that a water conservancy engineering company in Algeria purchased a gantry crane for a reinforced concrete pipe production plant. The water engineering company specializes in dam construction and the construction of water conveyance and wastewater purification systems. The old gantry crane had been used in an open-air environment for over 30 years and needed to be replaced to help reduce downtime caused by the older equipment.
Gantry cranes that move over long distances and operate on rails are responsible for handling the concrete tube forming frames and loading the dried and dismantled formwork. A 32 tonne capacity system capable of operating at a height of 17m was required to handle the heavy but fragile handling loads.
Five gantry cranes were refurbished with new electric hoists as well as power supply cables, radio control systems, switchgear and cable drums.
The electric hoist has a hook with safety latch and can travel safely vertically or horizontally with loads up to 80 tonnes and lifting heights of 6m-98m.
To fit within the narrow 155mm wide runway of the existing gantry crane, the crane company proposed a custom-made trolley with 16 rollers to evenly distribute load stresses.
The production lines within the factory were also refurbished and two bridge cranes were replaced. Like the external crane, the end beam and girder are retained, while an M6 electric hoist is installed, providing a lifting capacity of 7.5t at a height of 10m and a span of 20m.
In the vast field of water conservancy engineering, crane companies play a crucial role. They not only provide advanced lifting equipment, but also ensure the smooth and efficient completion of water conservancy projects through technological innovation and high-quality services. This article will take Dongqi Crane as an example to explore the role that crane companies should play in water conservancy engineering and how to do better.
Firstly, crane companies are an important support for water conservancy engineering construction. Water conservancy engineering involves a large number of tasks such as heavy object handling, equipment installation and dismantling, and these tasks cannot be separated from the help of cranes. Crane companies need to provide lifting equipment that can meet different engineering needs, including various models such as gantry cranes and bridge cranes. These devices need to have characteristics such as high precision, high efficiency, and high safety to meet the complex requirements of hydraulic engineering.
Secondly, crane companies should focus on technological innovation and research and development. With the continuous expansion of water conservancy engineering scale and the increase in complexity, the requirements for lifting equipment are also increasing. Crane companies need to continuously introduce new equipment to improve lifting capacity, stability, and intelligence level. At the same time, the company should also strengthen cooperation with research institutions, universities, and other organizations to jointly promote the innovative development of crane technology.
In addition, crane companies should also provide comprehensive service support. Hydraulic engineering often requires a long construction period, and crane companies need to provide timely equipment maintenance, upkeep, and repair services to ensure the stable operation of the equipment. At the same time, the company should also provide professional technical guidance and training to help construction personnel better operate and use lifting equipment.
