We had a successful crane cooperation with Indian quarry. Overhead cranes were used in quarries for a variety of lifting and moving tasks, such as lifting and transporting heavy blocks of stone, equipment, and materials. With their ability to handle large and heavy loads, overhead cranes can increase the efficiency and safety of quarry operations. Overhead cranes can also be customized to meet the specific needs of a quarry, such as the size and weight of the materials being lifted, the layout of the quarry, and other factors.
After communication, we learned that the quarry mainly mines granite and marble wasteland, the site environment is extremely harsh: the air is filled with a high concentration of stone powder dust, humidity varies greatly with the seasons, and high temperatures in the summer can reach more than 45 degrees Celsius. The customer wanted to add a new overhead crane for lifting rough slabs, barren materials and semi-finished products between the stone cutting shop and the finished goods yard.


We customized a 20-ton overhead crane solution for our client's quarry to meet its special operating environment and material handling needs. Adopting LD type double girder overhead crane, the whole machine consists of four parts: box-shaped bridge, crane operating mechanism, trolley and electrical equipment. In terms of operation mode, we provide wireless remote control and cab dual mode options, which are convenient for operators to move flexibly, but also can guarantee the safety of operation in complex environments.
We recommended this double girder overhead crane based on the customer's workplace and practical constraints.
The operating environment of the customer's quarry is usually complex, with a large amount of dust, noise, and vibration. At the same time, the materials in the quarry are mostly irregular large stones with large weight and irregular shape, which place higher demands on the lifting capacity and stability of the lifting equipment. Our LD-type overhead cranes have a wide range of applications and can cover the mechanical and equipment needs of industrial and mining enterprises, mining and metallurgy, and other infrastructure projects. Their rugged box-shaped bridge structure guarantees long-term stable operation in harsh environments.
LD type double girder overhead crane has reasonable structure, light deadweight, low wheel pressure and small limit size, which can effectively increase the operating area of the crane. Quarries tend to have less robust plant and infrastructure than industrial plants, so it is vital to reduce the equipment's demands on the structure of the plant. The lightweight design of LD cranes makes the requirements for building structures relatively low, saving customers the cost of plant renovation.
Quarry materials are usually heavy and irregularly shaped, requiring high lifting capacity for cranes. Double girder overhead cranes have two parallel main girders, which significantly increase load carrying capacity and stability, enable better load distribution and reduce stresses on structural components. With large lifting capacity, even load and smooth operation, LD type overhead travelling crane is very suitable for the handling and lifting operation of heavy stones in quarries.
LD type overhead travelling crane has strong adaptability to the working environment temperature and can operate normally within the range of -20℃ to +60℃. The high summer temperatures in Indian quarries, and the fact that the equipment often works in an open or semi-open environment, ensures that the equipment operates without interruption throughout the year. Crane steel has good corrosion resistance and anti-aging properties, adapting to the harsh environment of dusty and high humidity in the quarry.


A 20 ton double girder overhead crane provides even greater lifting capacity and stability compared to a single girder crane. It can lift and move heavy objects up to 20 tons in weight, making it useful in industries such as steel production, shipbuilding, and aerospace. The double girder design also allows for greater hook height and more precise movement, making it ideal for tasks that require precision and accuracy. Overall, it can improve efficiency, safety, and productivity in various industries.
