♦ Using a large steel locking carabiner attach the top end of the Micro Hauler system to a
substantial anchor (tripod, beam etc). Lock the carabiner.
♦ Pull on the cord that is attached to the cam to release the cam from holding the rope. Do not
remove the safety pin because that will completely open the cam and allow the rope to come
out of the guide channel. Pull the cord around the frame and secure it into the dimpled
"retainer catch" on the back of the frame. This allows the rope to move freely through the
system in both directions.
♦ Pull down on the steel carabiner that is attached to the lower pulley until it is low enough to
clip into the load (stretcher, equipment or rescuer). Holding the tail end of the rope lower the
load to the bottom of the space in which you will be working.
♦ Re-engage the cam to the rope by pulling down firmly on the attached cord and releasing.
♦ After the patient or litter is attached to the lower pulley with the carabiner the load can be
raised by pulling on the tail end of the rope.
♦ To make it easier to grip the rope, a handled ascender can be used. Open the cam on the
ascender and insert the tail end of the rope into the rope channel and re-engage the cam.
♦ To make raising the load even easier, attach a Skedco Rescue Stirrup to the handled rope
grab using a screw link or small carabiner. For your safety, attach the short end of the stirrup
(safety strap) to the front D ring on you harness. Insert your foot into one of the foot stirrups
(steps) at the bottom. Push down with the your foot. This will raise the load. Release the
pressure on your foot and slide the handled rope grab upward on the rope while raising your
foot. Press down with your foot again. Repeat this action until the load has been raised to a
point that you can remove it from the system.
Note: When hauling a rescue load long distances it will be necessary to change feet to prevent
over tiring of the leg muscles. This technique makes it much easier to raise the load and prevents
fatiguing your arm muscles which you will need to remove the load from the system. It is much
safer for you and the victim if your arms are not tired.
♦ The Micro Hauler can be used on a "piggyback" haul system rather than taking time to do a
complicated Z rig. To do this, select a very strong anchor. Attach the upper end of the Micro
Hauler to the anchor using a large steel locking carabiner. Attach a Rescuescender or other
suitable rope grab to the lower pulley.
♦ Attach the rope grab to the haul line. The haul line should be over an edge roller or suitable
rope protective device at the edge of the hole / roof / cliff to prevent abrasion. The haul
system will be horizontal. It is necessary to use prusiks or proper rope grabs on the haul line
to allow resetting and safe rope management.
♦ It is always necessary to have a proper belay line (safety line) attached to a separate strong
anchor in case the main anchor or other part of the system fails. (You must have redundant
"back up" on any rope rescue system.)
