The Harrington LX lever hoist with hook is a compact,
manually operated hoist featuring a die-cast aluminum body and
steel frame for mobility, tight workspaces, and durability. Low
headroom allows the hoist to fit in tight workspaces, a
free-chain adjusting mechanism facilitates rapid adjustments, and
a low pulling force requirement enables ease of use. The hook
and load hook have notched tips to hold latches more firmly
in place. In addition, a single-step reduction gear helps secure
the load for added safety. The Weston-style brake is completely
covered for protection from dirt, dust, and rain, and the grade
100 nickel-plated load chain is wear and corrosion resistant. The
handle grip is made of rubber for comfort, while the load chain
guide mechanism allows for smooth, quiet operation. The
Harrington LX lever hoist is used primarily in transportation,
construction, and plumbing applications to lift and move heavy
loads in small spaces, and can be employed for similar purposes
in other industries. This hoist is factory load tested to 125% of
rated capacity in accordance with American National Standards
Institute/American Society for Mechanical Engineers (ANSI/ASME)
requirements. It also complies with ANSI/ASME B30.21 and
ANSI/ASME HST-3M standards. When used according to manufacturer’s
recommendations, this product is covered by a two-year warranty
from date of shipment against defects in workmanship or
materials.
Hoists are mechanical devices that use relatively small as
of force to lift, lower, and move heavy loads. Manual hoists work
by transferring a force exerted by hand across a series of gears
that concentrate it into a force great enough to lift the
designated load. The lifting mechanism consists of a pulley with
a chain or cord and large wheel, or a ratchet lever attached to a
large wheel; a drive shaft; gear set; sprocket wheel threaded
with a load chain; and a lifting hook. The pulley or ratchet
turns the drive shaft, which engages the gears; the gears
interact to rotate the sprocket wheel and load chain, which pulls
the hook up to lift the load. When the force used to turn the
large wheel reaches the smaller sprocket wheel, it has become
concentrated enough to lift the load. Friction disk brakes called
Weston-style brakes are attached to the large wheel. These brakes
hold the load in place while the operator’s hands are released to
make the next pull, secure the load once it has been lifted, and
control the descent of load as it is lowered. Hoists can be
attached to structures such as cranes, ceilings, or walls by a
variety of methods including hook, trolley, deck, base, wall, and
ceiling s. They are used in a variety of industries
including transportation, construction, manufacturing, mining,
plumbing, foundry, and materials handling.
Capacity is the maximum rated load a hoist can handle. While
manufacturers may indicate they have tested a hoist beyond its
limits, operators should never attempt to lift a load heavier
than the maximum rated load. Pull force describes the a of
force that needs to be applied to lift a load. If a 1/2 ton
manual hoist specifies a pull force of 40 lbs., for example, the
operator needs to be able to pull a 40 lb. weight in order to
lift the maximum 1/2 ton (500 lb.) load. Headroom is the distance
from the bottom of the load hook to the top of the hoist. This is
the minimum a of vertical space needed for the hoist to hang
freely and operate correctly. Lift is the maximum vertical
distance the load hook can move a load.
Harrington Hoists manufactures hoists and cranes. The company,
founded in 1854 and headquartered in Manheim, PA, meets
International Organization for Standardization (ISO) standard
9001.
