Yale YEL series electric chain hoists are rugged, portable
hoists that provide quick, precise lifting. The hoists are
constructed of tough, but lightweight, die cast aluminum alloy
housings. An oil bath transmission, equipped with heat-treated,
alloy steel gears and an overload limiting clutch, provides
smooth and reliable operation. The electrical controls use an
ergonomically designed pushbutton station and a low voltage
circuit (24V standard, 115V optional). Terminal blocks allow for
easy voltage conversions on dual-voltage models.
Other features that ensure the safe operation of Yale electric
chain hoists include a magnetic disc brake that delivers sure
stopping and secure holding of the load. Adjustable upper and
lower limit switches regulate the load travel. As a standard,
hooks are supplied with safety latches. For additional safety,
a chain stop is attached to the slack end of the load chain.
Hoists are designed and tested in accordance with the
American Society of Mechanical Engineers Code B30.16,
“Safety Standard for Overhead Hoists.” Hoists are built in
compliance with CSA, file number LR 44484. Made in U.S.A.
* The 1HP, 115/230V models must have a dedicated power
circuit rated for at least 20A, 125V when they are wired for
115V. It is not unusual for these models to draw up to 20
amps at 115V when lifting at rated capacity depending on
the quality of the voltage source.
NOTE: The above data is the nominal motor current at full
load. At full load, it is not unusual for the hoist to draw
in excess of the values listed when lifting. It is critical to ensure
that the voltage at the reversing contactor does not drop below
10% of the nominal voltage while lifting a load. Low voltage will
result in higher amp draw, damage to the hoist, and potential
fire hazards. Yale Hoists is not responsible for any damages
caused by an inadequate power source.

*Note: YEL*PT models are equivalent to the corresponding YEL*TH,
but are supplied with a plain trolley and lug suspension. Model
numbers for these units are the same as above except “TH” is
replaced by “PT”.
