Engineered to withstand extreme overturning moments and wind load variables in CSP Salt Tower installations.
The global transition to dispatchable renewable energy has propelled Concentrated Solar Power (CSP), particularly Molten Salt Tower Solar Power, to the forefront of clean energy solutions. Unlike traditional photovoltaic (PV) systems, which are subject to diurnal fluctuations and grid instability, Salt Tower CSP stores thermal energy in molten salt, enabling seamless 24/7 power generation. This thermal storage capabilities allows solar energy to match peak load demands, making it a critical asset for national grids worldwide.
At the center of any Salt Tower CSP system is the heliostat field, containing thousands of dual-axis tracking mirrors. These heliostats must continuously reflect sunlight toward the receiver at the top of the tower with milliradian-level precision. Even minor deviations in alignment, caused by structural deflection or wind force, can lead to severe energy losses or receiver damage. Consequently, the selection of the underlying slewing bearing and drive systems represents one of the most critical structural decisions for solar field developers and EPC contractors globally.
Heliostat fields are typically situated in arid, flat, high-insolation desert areas—environments that are inherently prone to sudden wind gusts and sustained dust storms. To maintain target focus, the slewing bearing must support the dead load of the mirrors while absorbing extreme overturning moments (also known as tilting moments) and radial forces. This is where Jiangsu Manchen Transmission Technology Co., Ltd. excels, engineering solutions that offer high structural integrity and durability.
Our gearless and internal/external geared slewing bearings are designed to address these complex load distributions:
