First of all, if the space lends itself to a vertically mounted block and tackle, the problem is greatly reduced. However, if there is no overhead anchor available and the use of a portable overhead anchor such as a tripod is not feasible then a “lane” for the haul team may be necessary. At times, even the use of a vertically mounted block and tackle may require a solution to a congested working area.
Sometimes we are confronted with a very short throw between the mechanical advantage anchor point and the edge of the portal. This may cause multiple resets of the haul system, be it a piggyback system or a Z-Rig. These short throws with multiple resets will really slow down the progress of hauling the rescue package and can become a significant hazard when the need for rapid retrieval is needed.
If a single change of direction doesn’t quite solve the short throw problem, consider two, or even more changes of direction in order to position the haul team in an area thatthey can “walk the haul” using their leg strength instead of being bunched up and using their arm strength only. Of course, it gets to a point where too many changes of direction exhausts the equipment cache or creates so much friction that any advantage is lost.
As in any rescue situation, a good cohesive team is a great benefit. If the situation causes the team to be bunched up on top of each other, remember to scan the area for an opportunity to open things up a bit. Sometimes that change of direction does wonders for the ability of the team to take full advantage of their strength in numbers, and creates a situation where if needed, speed can be a lifesaver.
