PRODUCT DESCRIPTION
Infinity series winches are air powered, planetary geared units designed for and
intended for use as utility winches, with a Mechanism Classification of M5. They shall
not be used for lifting or moving personnel. They may be used to pull or lift loads at
various wire rope take-off angles. Winches can be equipped, with either an internal
automatic disc brake, a manual or automatic band brake, or a combination of both
disc and band brake.
The output from an externally mounted piston air motor is transmitted through a
coupling and shaft to the planetary reduction gear assembly. Output from the
planetary reduction gear assembly is connected to the wire rope drum through the
output shaft.
The disc brake assembly consisting of friction plates splined to a hub which in turn
is connected to the drive shaft from the air motor. Brake friction plates are clamped
to the drum shaft through a spring applied piston. The brake remains applied until
the winch control valve is operated and winch pay out or haul-in occurs. Air is
introduced into a chamber, which is formed between brake piston and brake
housing, causing the brake piston to react, compressing brake springs and releasing
friction plates allowing motor shaft to rotate. A power failure or sudden loss of air
will immediately cause the spring applied brake to engage. The band brake operates
by applying a friction force between brake band and winch drum. The manual brake
requires an operator to engage and disengage brake using a handle located on top
of brake band. The automatic band brake operation is similar to disc brake operation;
they are both fully disengaged in the haul-in and payout direction.
The design life of the winch is based on the application. Refer to ‘Maintenance
Intervals’ chart in Product Maintenance Information Manual. At the completion of
the specified maintenance intervals, the winch should be subjected to a complete
inspection by an Ingersoll Rand trained technician for determination of remaining
service life.
CE winches in addition to the above have drum guard, upper and lower limit
switches, overload protection and emergency stop as standard features, and are
compliant with CE directives.
