Hoist Snag Detection using Crane Sentry® Side Pull

hoist sway controlSnagging can occur when a wire hoist accidentally gets caught on a piece of equipment. This can happen quickly and it may be difficult for a crane operator to react in time. Hoist snag detection systems can help to detect and prevent crane movement if a load gets caught.

When wire rope hoists are lowered they present a chance of becoming snagged on equipment or obstacles within a facility. This even more prevalent in facilities with dual elevation crane runways, where the wire rope of the upper crane can snag the lower crane’s bridge.

Either condition presents an extreme safety risk because of what can happen to a load in motion. These incidents can result in injured personnel and damaged product or equipment.

Laser-View Technologies’ Crane Sentry® Hoist Side Pull can be used to detect a snag condition (also referred to as anti-snag) and when properly installed, can be used to disable bridge movement through the built in relay contacts.

The side pull detection system includes a controller with real-time angle readings and permits the setting of threshold limits. Versions are available as omnidirectional detection sensors to detect a snag pulling the wire rope either with the hoist drum or against the drum.
