An ideal confined space support structure for one or more mechanical devices and your choice of Advanced™ portable or permanent bases. Integrated 5,000 lb. (22 kN) mast anchorage point provides user with a secondary ANSI rated fall arrest anchorage point for maximum worker safety. Engineered system incorporates a fall arrest rated anchorage point with a minimum strength rating of 1,800 lb. The extension provides the flexibility to change the overall mast height of your system in larger increments. Adjustable length of davit ensures mechanical device lifeline(s) are always centered over the confined space. Adjustable vertical height of 36.5 in. to 54.5 in. eliminates the need for custom length masts and extensions allowing one system to cover a range of different confined space scenarios. Built-in primary and secondary pulleys route lifelines of two mechanical devices for smooth, efficient rescue and work support operations. Provides user with up to a 5,000 lb. rated anchor point for a self retracting lifeline or similar fall arrest device for added safety. Simple detent style bracket offers extremely fast and safe mechanical device installation. Both primary and secondary mechanical devices can be attached to the mast for added flexibility.
