Quality and performance
Ingersoll Rand hoists can be equipped with
a variety of optional features that can be matched
to the specifications of almost any job. Their long
operating life, cost-eective service and
maintenance, and dependable performance are
supported by a host of standard features.
Rotary-vane air motors
These powerful, self-cooling rotary motors keep
Ingersoll Rand hoists at peak performance in
high-temperature situations. And, because they
are air-powered, they further reduce the chance
of causing sparks in a volatile environment.
Complete operator control
A pressure pendent or pull chain puts complete
control of the hoist in the operator’s hand. These
hoists respond immediately to an operator’s
“inching” commands.
External brake adjustment
Easily customizes the sensitivity of the hoist to
the load range for any application. This results in
ease of operation with better spotting, feathering,
and overall control.
Fast, ecient load handling
Rotary-vane air motors and ecient gearing
combine to deliver one of the fastest li speeds
available. Gear ratios have been calculated to
yield the lowest possible air consumption.
Job-matched performance
Numerous options allow Ingersoll Rand hoists to be
matched to specific application requirements,
including link or roller load chains, hook types,
manual and power trolleys, pull chain or pendent
control, standard and spark-resistant, and 300-lb to
2-ton capacities.
Clean and quiet
For applications and environments that require
clean air, exhaust can be piped away. A two-stage
filtration system removes foreign matter from air
supplies so motors can operate at peak performance
with longer operating lives.
Easy installation
Lightweight and convenient, Ingersoll Rand hoists
are easier to install than any other model. Even in
small, confined areas, they can be installed and
removed with minimal eort.
