Safety Device for Construction Hoist
Our Safety Devices for Construction Hoists are critical life-saving components engineered to protect personnel and materials in rack and pinion lifts. These systems provide automatic protection against uncontrolled descent or overspeed conditions, instantly engaging to stop the cage safely in the event of drive system failure, rope breakage, or governor malfunction.
Key Features
Dual-Stage Protection: Integrated systems combine overspeed sensing and mechanical braking for comprehensive fail-safe operation.
Centrifugal Overspeed Governor: Precision-balanced governor mechanism triggers at preset overspeed thresholds (typically 40-60% above rated speed), activating the safety gear without electrical power.
Progressive Safety Gear: Wedge-type or roller-type safety gears engage gradually, providing controlled deceleration rather than abrupt stopping, minimizing shock to passengers and structure.
Rope-Operated Auxiliary Safety: Optional rope-operated systems provide manual emergency stopping capability from within the cage.
Applications
Construction Hoists: Safety systems for rack and pinion personnel and material lifts.
Compatible Hoist Types:
Personnel hoists (passenger lifts)
