Alternate option: The R550 Rescue & Escape Device
is also configured to allow a Power Drill (minimum 1/2"
chuck and 400 lbf-in torque) to be attached to the
center of the Rescue Hub which can be used in remote
assisted rescues to raise the fall victim. (See Table 1
on this page for an example of lifting distances.) Attach
the Power Drill directly to the shaft at the center of the
Rescue Hub (see Figure 8). Use the attached Power
Drill to rotate the Rescue Hub to raise the victim's
weight from the fall arrest subsystem and onto the
R550 Rescue & Escape Device. Secure the Free End of
the lifeline with the R550 Rescue and Escape Device's
Pigtail and Cam Cleats to prevent unintentional descent
(see Figure 6). Detach the Power Drill by lowering the
victim's weight onto the unit's Pigtail and Cam Cleats
and then releasing the Power Drill from the center of
the Rescue Hub. Once the Powered Drill is removed,
disconnect the Victim's fall arrest subsystem (Lanyard,
etc.)

* Lifting distance based on full battery charge, ambient temperature of 72° F (22° C).
** High speeds with high loads not recommended.
NOTe: Power Drill lifting capabilities will vary with victim load, battery charge, drill model, and
environmental conditions. The lowest drill speed setting is recommended to maximize battery life and to
reduce the risk of damaging the drill or the R550 Descender. Loads greater than 310 lbs (141 kg) should
not be lifted with the Power Drill option. Lifting in reverse direction will typically decrease the lifting distance
capacity of a single battery charge.
step 4.
Prepare the Lifeline for Descent: Prior to descent, the section of lifeline between the user and
the R550 Descender must be tightened to remove any slack. Tighten the lifeline by pulling on the
free end of the lifeline until slack between the user and R550 Descender is removed. Once the
lifeline is taut, hold the free end of the lifeline tightly until descent is initiated.
step 5.
Descend to safety: Release the free end of the lifeline to initiate descent. Descent speed will be
automatically controlled to a rate described in Section 1.2 C by the R550 Descender's centrifugal
brake. Descent may be interrupted by firmly grasping the free end of the lifeline (see Figure 6).
Bend your knees to prepare for landing. After landing, disconnect the lifeline from the body
support. Record all descents in the Descent Log (Section 10).
cAUTION:
The R550 Rescue & Escape Device may become hot during use which could injure the user if parts other
than those used to control the descent are touched. Use beyond the specified load and descent length limits may
generate excessive heat which could damage the descent line.

usE - sIMuLTANEous REsCuE/EsCAPE: In situations where the fall victim requires assistance,
simultaneous rescue/escape allows a rescuer
WARNING:
Two person descents with the R550 Rescue & Escape Device should not exceed a total combined weight
(including tools, clothing, body support, etc.) of 620 lbs (282 kg) and a descent distance of 574 ft. (175 m).
step 1.
Descend to the victim: In situations where the fall victim is suspended by their existing Fall
Arrest subsystem, it will be necessary for the rescuer to descend to the victim's location to
provide assistance. Descend to the victim per the steps in Section 3.4.
IMPORTANT:
holding the free end of the rope (See Figure 6). If a secondary rescuer is available at the R550 Descender,
the free end of the rope can be passed through the Pigtail and then secured in the Cam Cleats to prevent
unintentional descent while the primary rescuer is securing the victim.
step 2.
Connect the victim to the R550 Rescue & Escape Device: Connect a Rescue Lanyard (or
similar equipment) between the Lifeline Snap Hook connected to the Rescuer's Full Body Harness
Front D-Ring or the Back D-Ring on the Victim's Full Body Harness (Figure 7).
WARNING:
