A crane limit switch is a safety device used in cranes and hoisting equipment to control the movement range of the crane’s lifting or travel mechanisms. Its main function is to prevent the crane from moving beyond its safe operating limits, such as over-lifting, over-lowering, or over-traveling in any direction.

Photoelectric Limit Switch: Offers non-contact detection using infrared or laser sensors. Ideal for applications requiring high-speed response, precision, and long service life in dusty or corrosive environments.
Height Limiter: Automatically detects and controls the maximum lifting height, preventing over-hoisting and ensuring safe operation. Features adjustable setpoints, durable construction, and compatibility with various crane types.
Cross Limiter: Designed to control lateral trolley movement, the cross limiter ensures smooth horizontal travel and prevents collisions or end-travel impacts. Built for high reliability in overhead and gantry cranes.
Travel Limiter: Regulates the longitudinal movement of cranes along tracks. Ensures precise stopping at end zones or critical points, reducing wear and increasing safety in industrial and warehouse settings.

Stops or slows down the crane when it reaches a preset limit.
Prevents damage to the crane structure or hoist.
Protects operators and materials from unsafe movements.
Ensures accurate positioning during lifting or traveling.

Widely used in overhead cranes, gantry cranes, electric hoists, and automated lifting systems in sectors like manufacturing, logistics, construction, and material handling.
