Planning the Use

3.1.1 Set up
• Erect the tripod according to the tripod instructions. Erect only to height where the tripod head is reachable by the
installer.
• Place the winch to the side of the tripod leg.
• See Fig. 3 and follow the installation label in section 8.
• Extract 9" of winch cable and reeve over the pulley.
• Hang carabiner and pulley to tripod head anchors on the side. See Fig. 4. The winch snaphook must be hung
towards the inside of the tripod.

3.1.2 Rescue Plan

Always have a rescue plan when using the winch for lifting or lowering personnel. A fall arrest system should always be
used when lifting or lowering personnel, in case disconnection of the winch line is necessary or in case failure of the
winch or winch anchorage means occurs. A backup lifeline such as a SRL with retrieval function, that raises and lowers,
is recommended to provide immediate rescue capability
3.2

Lowering a Load

When using the winch for lifting / lowering of personnel, an independent fall arrest system is required. The MSA SRL
with retrieval function or other MSA SRL is recommended.
Other fall arrest systems are also available from MSA.
To lower a load with personnel suspended, rotate the crank handle counterclockwise. To extract line from the winch
when there is no suspended load, rotate the handle counterclockwise while pulling on the line with at least 15 pounds
of force. To resume lifting, make clockwise revolutions of the crank handle.
3.3

Suspending a Load

To suspend a load, slowly release the crank handle.
3.4

Lifting a Load

WARNING!
In the event of a fall, lift before lowering to disengage the secondary brake pawls. Lift first at least one half turn of the
drum before attempting to lower. Unless the secondary brake pawls are disengaged after a fall, the winch will not pay
out line.
To lift a load, rotate the crank handle clockwise. A clicking sound will be heard as line is reeled in. When reeling in line,
check to be sure the line wraps evenly and tightly around the drum.
