Crane Limit Switch for Enhanced Safety in Crane Operations

Designed to prevent over - lifting in overhead cranes, Yueqing Huilong’s upper limit switch is a critical safety component in material handling. This switch features a robust cast steel housing (weight 3.5kg) that withstands heavy impacts, while the adjustable trigger arm (length 300 - 500mm) accommodates different crane configurations. The internal mercury - free tilt switch ensures reliable operation, with a response time of ≤0.2s to stop crane movement. Equipped with a 10A/250V AC contactor, it directly controls the hoist motor, eliminating the need for additional relays. The switch is rated IP54 for dust and water protection, suitable for outdoor crane operations. A unique anti - vibration mount reduces false triggering from mechanical shocks, making it essential in construction, shipyards, and heavy industry.
