Tower Crane Double Top & Lower Limit Switch Safety Spare Parts
These double top and lower limit switches are critical safety components for tower cranes. Made with high-quality materials, they feature sensitive response, stable performance and strong resistance to vibration, dust and corrosion. They effectively restrict the operating range of the hoisting mechanism, preventing over-travel accidents during lifting operations. Compact and durable, they are easy to mount and ideal for replacement and regular maintenance on construction sites.
