Häst Rescue Frame - Bipod
The Häst A-frame, or bipod, shown to the left, is the culmination of many months of imagination, design, tool making, and just plain hard work.  The result is a frame that is simple and very strong that can be utilized in those evolutions where a rescue is required but one either does not have access to a crane or the area is inaccessible to heavy equipment.  Constructed entirely of aluminum alloy, this frame is no weakling when it comes to loads.  It supported this 2700 pound car and did not break a sweat!  Later in this year, this frame will be tested using loads that far exceed any other frame on the market.  The usable height of this frame, from the ground up to the ring, is 18 feet 6 inches, giving plenty of room for almost any type of rescue that may be encountered.

One of the key features of our bipod frame head is the use of a "floating attachment" point rather than a fixed plate.  The large red ring in the center, suspended under the cross member by high strength rescue rope, serves as the single attachment point for both the rigging lines as well as the load.  This configuration is auto adjusting, keeping the downward forces in the frame columns in the absolute center, and thus eliminating all bending forces.
  On the bottom of the column is the foot assembly.  Made of 1/2 inch plate, the foot is basically a massive hinge with bracing placed in those directions to resist the downward forces from the column.  Along the outside edges of the foot are over a dozen holes that can be used either for the 1 inch thick stakes as shown in the picture, or for attaching rigging lines in the event that the foot is placed on concrete and remote anchor points are required.  In this photograph, the rubber pad is not being used, allowing the cleats to sink into the soft groung.  Also, one can see the four grease fittings to keep the hinge lubricated.

The Components

Bipod Head

The bipod head is constructed entirely of aluminum tube.  This gives it strength.  In addition, the tubes are machined to exactly fit to one another prior to welding.  This also gives this strength.  The support sling is made of low stretch 10,000 pound rescue rope supporting a 1 inch steel ring that gives plenty of room for all the rigging lines as well as the lines for the load.  The two top pieces are there to keep the rope aligned correctly.  However, they likewise add to the overall strength of the top.

The weight of the head, as shown, is 24 pounds (11 kg)
Support Columns  

These two support columns make up each leg.  The upper one to the left nests inside the lower one to the right.  Like our spread bar, the hole through the upper column has a sleeve that helps guide the pin when inserted.  The lower column has holes drilled every 12 inches for adjustments in height, especially if on uneven ground.  The holes are precision drilled and are only 1/32" larger than the pin.

For a monopod, only one set of support columns is needed.  Likewise, for the tripod head, one would need three sets.

The upper column, 12 feet long, weighs 41 pounds (18.6 kg)
The lower column, 10 feet long, weighs 35 pounds (16 kg)

 
Hinged Foot

The hinged foot fits inside the lower support column, as it is made of the same tubing as the upper column.  The rest of the foot is 1/2 plate.  As one can see, there are many holes around the perimeter for use with 1 inch stakes or to attach carabiners for stabilizing the legs with a remote anchor or for use in the haul system for raising the rescued animal.

The foot, as shown, weighs 24 pounds (11 kg)

For all the parts shown above, the edges
 as well as the holes have been rounded for smooth handling.
 

The price for the Häst Rescue Frame Bipod is $4260, which includes the components shown above, but does not include crating and freight.  For now, expect a lead time of a couple of months.   Our goal, however, to be able to reduce this time considerably.

There are five different "stances" available, from the narrow Model 16 to the wide stance Model 24 which is shown above.  The number indicates the degrees from vertical that the columns are set.   The wider stance models allow for more working room between the columns as well as a much more stable environment.  We recommend the Model 24.  However, circumstances or space restrictions may necessitate that a more narrow model be selected.  Download the PDF Bipod Selection Chart to see the space requirements for each stance.  Remember that the dimensions are approximate and should only be used as a guide for selection, and that the interior working space is less than the outside overall dimension.

Initially, only the frame as shown will be available.  However, we are working to compile a complete package that will include the anchor stakes seen in the foot assembly picture along with foot pads, a handy gear bag for the whole frame as well as other accessories.
In the design and use of any type of structure, it is important to understand the loads that may be encountered in lifting either an object or animal.  Safe use of these frames is paramount!  For a discussion on loads, take a moment and refer to Frame Loading.
