We introduced our 5-piece Retrieval System to the safety industry 25 years ago, and it is still our best seller for confined space retrieval.  To further illustrate its popularity, at least 5 other companies in Canada and the U.S. have reproduced the system, confirming the age-old adage that imitation is the highest form of flattery.  Today we are proud of the fact that hundreds of the UH500 5-piece Retrieval exist throughout North America.  Its high demand can be attributed not only to its functionality but its indestructability; it simply does not wear out.

The 5-piece Retrieval System consists of:

  • UH504-18” Offset Mast
  • UH502-CP 30” Centre Post
  • UH503-X 3-piece Expandable Base

General Information: 

  • Serves vertical, horizontal, and counterweight applications.
  • Mast is capable of mounting more than one winch or a combination of winches and self-retracting lifelines.
  • Mast pivots 90 degrees in 2 directions, allowing the entrant to be moved away from the man-way entrance.
  • Mast is made from an aluminum composite, making it lighter and stronger.
  • Fire department style Uni-Hoist raises the height to 89” (2261 mm.).
  • Depending upon terrain, base may be used with or without leveling legs.
