1.0 LYNX HOIST DESCRIPTION
The Rose Lynx Hoist is suitable for lifting, lowering and positioning either personnel or materials. It is
designed for use in conjunction with Rose anchorage connectors, fall arresters and other components to
make up complete systems for manriding, work positioning, materials handling, emergency rescue and
evacuation. Rose components are available to provide backup fall arrest for all such systems.
There are three standard Lynx Hoist types. They differ only in the configuration of their integral mounting
brackets. Two standard line lengths are available in either galvanized or stainless steel wire rope. Other line
lengths can be special ordered. All hoist models are equipped with an emergency drive and air drive
adapter. All standard Lynx Hoists can be retrofitted with these upgrades. The principle Hoist specifications
are present in Appendix A. A list of Lynx Hoist types and models is provided in Appendix B. Accessories
and companion products, including the Hoist air drive, are listed in Appendix C. All models meet current
regulations for personnel related mechanical devices.
The three standard Lynx Hoist types are:
• Figure 4: Side-mount hoist for installation on the Lynx Tripod.
• Figure 5: Boom-mount hoist with an extension frame and anchorage hook for installation on the Lynx
Tripod and a variety of other suitable anchorage connectors
• Figure 6: Socket-mount hoist for use with the Rose vehicle mounted davit
These three mounting arrangements may be interfaced with other anchorage connectors approved by
Rose. Additionally, custom anchorage connectors and mounting brackets may be obtained from Rose as
part of engineered systems for specific applications.
All Lynx Hoists embody several standard features:

! CAUTION
The user should prevent the buildup of slack line that would allow free fall.
Internal mechanisms of the hoist are protected by a formed steel housing. All parts are zinc chromate plated
to resist corrosion. The load end of the line is terminated with a self-locking swivel snaphook which requires
two separate and distinct manipulations to unlock and open the snap gate. When released, the snap gate will
automatically close and lock. See Figure 3.
The hoist has a level wind mechanism which help the guide line to lay and wrap tightly around the drum.
! CAUTION
To prevent loose coils of line on the drum, always maintain at least 15 lbs
(6.75 kg) of tension on the line when paying it out.
The hoist is normally operated with the standard manual crank handle shown in Figure 1. To extract line or
lower a load, rotate the handle in a counterclockwise direction. To retract line or raise a load, rotate the handle
in a clockwise direction. To suspend a load, release the handle. A brake in the drive mechanism inhibits the
drum from free wheeling. The brake operates even when the crank handle is removed for attachment of the
optional air drive.
Air Drive Option
An optional air drive system – P/N 506420 – is available for use in applications requiring long line runs or
rapid retrieval of a load. The air drive system consists of an air-driven motor with a filter-lubricator that
cleans, lubricates and regulates the pressure of plant air or compressed air supplied to the motor.

Caution!
Gate should not open under pressure from any direction unless
unlocked. If this condition is not met, or if any steps A, B or C cannot
be performed properly, remove
the snaphook from service.
EMERGENCY DRIVE
All hoists are equipped with an optional emergency drive. See Figure 2. Activation of the emergency drive
bypasses the load-limiting clutch and permits emergency lifting in excess of the maximum rated working
load.
! CAUTION
The emergency drive must be used only in case of an emergency where loads
in excess of the rated working load must be raised or lowered. Immediately
after emergency drive use, the hoist must be removed from service and
returned to the manufacturer for inspection and service. Before use, the hoist
must be inspected for presence of the emergency drive activation pin.
Remove the hoist from use if this pin is missing.

1.1 DESCRIPTION OF SIDE-MOUNT HOIST
The Side-Mount hoist is designed for use with the Lynx Tripod – P/N 10022050, P/N 10022051. See Figure
4. It may also be used with other anchorage connectors approved by Rose. The Side-Mount hoist serves
as the primary lifting-lowering device for systems which use the tripod to position equipment for confined
space entry above the area to be accessed. The hoist mounts to the side of the tripod leg. This position
permits operation of the hoist by a surface attendant positioned away from the confined space access point,
maximizes the usable space to the interior of the tripod and increases stability by lowering the tripod’s center
of gravity.
When installed on the Lynx Tripod, a pulley mounting bracket and Side-Mount pulley – P/N 506473 – are
required for rigging the Side-Mount hoist line at the tripod head. This permits full use of the interior headroom
of the tripod.
Note: When using the hoist for lifting-lowering of personnel, an independent fall arrest system is required. The
Rose Lynx Rescuer retractable lifeline or Rose Dyna-Lock™ is recommended. See section 1.4.2. Other fall
arrest systems are also available from Rose.

1.2 DESCRIPTION OF BOOM-MOUNT HOIST
The Boom-Mount hoist consists of the basic hoist with an integral 42 in (107 cm) extension frame. See
Figure 5. The Boom-Mount hoist is compatible with the Lynx Tripod, and can also be used in numerous
applications with a variety of anchorage connectors.
The extension frame enable operation of the hoist by a user positioned away from the area to be accessed.
Connection of the hoist to a suitable anchorage connector over the work area is enabled by a connector
yoke/anchorage hook assembly integrally mounted at the end of the extension frame. Both the connector
yoke and anchorage hook will swivel, permitting the user to position the anchorage hook for speedy
connection to the previously installed anchorage connector.

1.3 DESCRIPTION OF SOCKET-MOUNT HOIST
The Socket-Mount hoist is manufactured for use with the Rose Davitruck System (P/N 506356) which is a
vehicle-mounted system. The vehicle-mounted davit provides an anchorage connection means in a variety
of situations where anchorage connectors cannot be mounted directly above the work area. The davit may
be rotated through 360 degrees, permitting attachment of equipment for fall protection and materials handling
at a stable work surface, and subsequent positioning of personnel and/or materials over the work area. See
Figure 6.

1.4 ACCESSORIES AND COMP ANION PRODUCTS
A list of Lynx Hoist accessories and companion products is provided in Appendix C.
! CAUTION
Under no circumstances should products of other manufacturers be used in
conjuction with Rose products or systems without the prior written consent of
Rose Manufacturing Company. Use of incompatible products by other manufacturers may result in serious personal injury or death, and damage to
equipment.
2.0 INSTALLATION
2.1 INSTALLING THE BOOM-MOUNT HOIST TO OTHER
ANCHORAGES
The anchorage used to suspend the hoist for personnel or materials hoisting must be strong enough to
support the load with an adequate safety factor. The required safety factors are 10:1 for personnel, 5:1 for
materials. For personnel hoisting, the anchorage must have a strength of at least 5,000 lbs (22 kN). A backup
fall arrest system must be utilized.
! CAUTION
Select the anchorage and anchorage connector with which the hoist will be
used under the guidance of a qualified person. If any question arises as the
suitability of the anchorage connector for the intended application,
discontinue installation of the hoist and contact the manufacturer.
! CAUTION
Install the installation snaphook so that unwanted movement of the snap
and attached hoist is prevented. Otherwise, movement of a load may cause
sudden movement of the snaphook and result in loss of balance by the
operator.
2.2 INSTALLING THE SOCKET-MOUNT HOIST
The socket-mount hoist is designed for installation of Rose vehicle-mounted davits. Socket-mount hoists are
supplied with a mounting tube which interfaces with the boom arm of the davit. To install the hoist, follow the
steps below in sequence and refer to Figure 16.

INSTALLATION OF SOCKET-MOUNT HOIST2.5.1
Step 1: Slide the hoist-mounting tube (A) into end of davit arm (B). If installing the hoist on a DaviTruck
vehicle-mounted davit, first erect the DaviTruck in accordance with the instructions and labels
accompanying that product.
Step 2: Align the holes in the davit arm with the holes in the hoist-mounting tube.
Step 3: Insert the davit boom arm clevis pin (C) through the holes in the davit arm and mounting tube.
Step 4: Secure the clevis pin with the hairpin cotter (D).
3.0 OPERATING INSTRUCTIONS
! CAUTION
Inspect the hoist according to the instructions in Section 4.0 of this manual
before and after each use. Also inspect each component with which the hoist
will be used according to the instructions accompanying that product. If any
component is found to be damaged, altered or defective, immediately
remove the system from use. Do not attempt field repair of equipment, and do
not attempt use of the system without first replacing any damaged, altered or
defective component.
3.1 RESCUE PLAN
Always have a rescue plan when using the hoist for lifting or lowering personnel. A fall arrest system should
always be used when lifting or lowering personnel, in case disconnection of the hoist line is necessary or
in case failure of the hoist or hoist anchorage means occurs. A backup lifeline such as the Lynx Rescuer,
which has an integral rescue winch that raises and lowers, is recommended to provide immediate rescue
capability.
