Construction Hoist Overspeed Safety Device

Description

Construction Hoist Overspeed Safety Device

he Construction Hoist Overspeed Safety Device is a mechanical safety component used on compatible rack-and-pinion construction hoists. It is designed to activate the braking mechanism when the hoist cage reaches an overspeed condition during descent.

The safety device works independently of the normal drive system and provides an additional mechanical safeguard for passenger and material construction hoists.

SAJ series safety devices are commonly used on rack-and-pinion construction hoists and are available in different models and rated parameters. The correct model, rated speed, tripping speed and mounting configuration must be confirmed before replacement.
