Case studies on enhancing safety through improved slewing drive technology


Slewing drives are crucial components used in heavy-duty machinery for the rotation of the machine’s boom or arm. The technology behind slewing drives has significantly evolved over the years, resulting in improved safety and higher efficiency. In this article, we will explore some case studies that highlight the significance of improved slewing drive technology in enhancing safety.

Case Study 1: Wind Energy

Wind energy is a rapidly growing industry, and it heavily relies on the use of large cranes for the installation of wind turbines. The use of high-quality slewing drives in these cranes plays a vital role in enhancing safety and efficiency. In one case, a wind farm installation company replaced traditional slew bearings with a slewing drive, resulting in a 50% reduction in crane downtime and a 35% increase in efficiency.

Case Study 2: Mining

Mining operations use heavy-duty equipment such as excavators and loaders, which require regular maintenance and replacement of parts. Slewing drives used in these machines are crucial in ensuring the safety of the workers and the efficient operation of the equipment. In one case, a mining company replaced their traditional slew bearings with a slewing drive, resulting in a 30% reduction in maintenance time and a 40% increase in output.

Case Study 3: Solar Energy

Solar energy is becoming an increasingly popular source of renewable energy, and the installation of solar panels requires the use of heavy-duty machinery such as solar trackers. Slewing drives in these machines play a fundamental role in ensuring accurate tracking of the sun’s movement and the safe operation of the trackers. In one case, a solar installation company replaced their traditional slew bearing with a slewing drive, resulting in a 25% increase in energy output and a 50% reduction in maintenance costs.


Improved slewing drive technology has played a significant role in enhancing safety and efficiency in various industries. The case studies discussed highlight the importance of using high-quality slewing drives in heavy-duty machinery. As technology continues to evolve, we can expect further improvements in the design and functionality of slewing drives, leading to safer and more efficient operations.
