CAPSTAN USE
Presently, Braden uses only one type of capstan – the quick disconnect bayonet type. Other types have been used
previously, including a bolt-on type.
To install the bayonet type capstan, push the capstan onto the extension shaft, against spring tension, then turn the
capstan counter-clockwise (CCW) to the stop. Release the capstan and verify the spring has pushed the capstan
back outward into the “lock” position.
HP35 winches use a load holding brake that must be released when the winch is operated in both directions. This al-
lows the rope to be wound around the capstan in either direction during capstan use.
• BEFORE installing a bayonet type capstan, make certain the spring is properly located in the bore. The spring
holds the capstan in the “lock” position on the extension shaft. If the spring is missing or omitted, the capstan may
come off the shaft and cause a sudden loss of load control which may result in property damage, injury or death.
Also, closely inspect the edges of the of the lock pocket to insure they are still sharp and not rounded from use.
A badly worn lock pocket may prevent the capstan from locking securely to the shaft, which could allow the cap-
stan to come off the shaft and cause a sudden loss of load control which may result in property damage, injury or
death.
• Make certain the vehicle is positioned such that the load line and hand line are perpendicular to the capstan barrel.
DO NOT allow rope to pull against either fl ange of the capstan, as the rope may get damaged or “jump” over the
fl ange and cause a sudden loss of load control which may result in property damage, injury or death.
• If a bolt-on type of capstan is used, make certain that a ¾ in. X 5-¼ in. Grade 8 (M20 X 133 mm, Class 10.9) cap-
screw and self-locking hex nut are used. A soft bolt or pin may shear off and cause a sudden loss of load control
which may result in property damage, injury or death.
Exposed areas of capstans and extension shafts are extremely dangerous. Clothing and other items may become
entangled and wrapped around the rotating shaft. Install appropriate guarding to prevent any part of the body or
clothing from making contact with the shaft when it is rotating. Failure to provide adequate guarding could result in
property damage, injury or death.
