Coffing JLC 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. With a pushbutton station that
fits comfortably in one hand, the operator can safely control the
hoist while the other hand is free to guide the load. The
electrical controls use 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 Coffing 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.
Coffing electric 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 (JLC1032-1, JLC2016-1,
JLC4008-1) 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. Coffing Hoists is not responsible for any damages
caused by an inadequate power source.
