• Electric or hydraulic drive system: The heart of a slew device is its drive system. It can use electric motors, hydraulic motors or other types of drive mechanisms, with different energy types chosen depending on the requirements of the application. This system is responsible for providing the power for rotation.
• Axis of rotation: The unit is equipped with one or more axes of rotation, which are arranged in a horizontal or vertical direction, depending on the design of the device. The material and structural design of the shaft must be strong enough to withstand the forces and pressures of rotational motion.
