OPTIONS
COUNTERCLOCKWISE ROTATION:
The drum rotation of the standard PULLMASTER Model H25 planetary winch is clockwise for hoisting when
looking at the hydraulic motor of the winch. Drum rotation for counterclockwise hoisting direction is available as
an option.
INTERNAL CIRCULATION:
The PULLMASTER Model H25-7-86-X has an external circulation flow supply line to cool the brake. Internal
circulation is available as an option.
EXTERNAL BRAKE RELEASE:
PULLMASTER planetary winches can be supplied with an external brake release which permits release of the
automatic disc brake from an external pressure source.
CABLE DRUM SIZES:
Aside from the standard drum sizes listed in APPENDIX A, the PULLMASTER Model H25 planetary winch can
be supplied with optional drums to accommodate large wire rope storage capacity.
DRUM GROOVING:
Cable drums for the PULLMASTER Model H25 planetary winch can be grooved. Where this option is a
requirement, it is necessary to state the size of wire rope which is to be used with the winch.
OPTIONAL GEAR SECTION FOR THE HYDRAULIC MOTOR:
The performance of the standard PULLMASTER Model H25 planetary winch may be changed by using a different
displacement motor. (Contact the factory for performance information.)
HYDRAULIC MOTORS FOR HIGH PRESSURE HYDRAULIC SYSTEMS:
The operating pressure of the PULLMASTER Model H25 planetary winch is limited to 2500 psi (172 bar). For
hydraulic systems operating with a higher range of hydraulic pressure, the winch can be supplied with a hydraulic
piston motor, which will provide for the same basic performance in terms of line pull and line speed capacity.
(Contact the factory for this requirement.)
FREESPOOLING:
This option permits wire rope being pulled off the cable drum by an operator. Freespooling should not be
confused with free fall. The freespool clutch cannot be disengaged or re-engaged with a load on the wire rope
or while the cable drum is turning.
The PULLMASTER WINCH CORPORATION will consider other options for quantity requirements.
FAILURE TO PROPERLY VENT EXTERNAL BRAKE RELEASE
PORT WILL TRAP BRAKE PRESSURE AND ALLOW THE
LOAD TO DROP, CAUSING PROPERTY DAMAGE, SEVERE
INJURY OR DEATH. WINCHES SUPPLIED WITH EXTERNAL
RELEASE OPTION MUST BE CONNECTED ACCORDING
TO “TYPICAL HYDRAULIC CIRCUIT”.
