Designed specifically for hoisting equipment, Yueqing Huilong’s limit switch hoist prevents over - lifting and over - lowering accidents in cranes, winches, and elevators. The switch features a heavy - duty cast iron housing (weighing 1.2kg) that resists impact and corrosion, ideal for outdoor construction sites. Its lever arm, constructed from hardened steel, can withstand 200kg of force, while the internal reed switch offers non - contact operation, extending service life to 5 million cycles. The switch supports multi - stage limit settings, allowing precise control of hoist travel limits (up to 30m adjustment range). Equipped with an IP65 protection rating, it performs reliably in dusty and rainy conditions. A unique self - lubricating bearing reduces friction, minimizing maintenance needs, making it a preferred choice for port logistics and manufacturing plants.
