The Harrington LB lever hoist with hook is a compact,
manually operated hoist with all steel construction for strength;
and low headroom, a handle with 360-degree rotation and 15-degree
recovery strokes, and and load hooks with 360 degree
rotations for work in small spaces and at any angle. This hoist
has a spring-loaded freewheel to facilitate rapid adjustment of
the load chain with one hand, and helps prevent accidental
freewheeling when a load is on the chain. The Weston-style brake
has two moisture-resistant brake pads, four braking surfaces, and
two brake pawls to help ensure reliability. The brake is
completely covered for protection from dirt and moisture. The
forged, heat-treated alloy steel hook and load hook resist
fracture under stress. The hook is a pivot and swivel hook
for use with rigging applications. The grade 100 heat-treated
load chain is nickel-plated and corrosion resistant. This hoist
also has a rubber handle grip for non-slip operation, and
machined, heat-treated, split load double reduction gears for
durability. The Harrington LB lever hoist is typically used in
construction, mining, manufacturing, and shipbuilding
applications, but can be employed for similar purposes in other
industries. This hoist is factory load tested to 125% of rated
load 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 devices that use relatively small as of force to
lift, lower, and move heavy loads. Manual hoists transfer a
small, hand-exerted force across a series of gears or pulleys
that multiply the force into one large enough to lift the
designated load. This makes it possible for an operator to manage
heavy loads. The manual force is usually applied using a hand
chain, lever, or ratchet pulley, lifting the load by a hook
attached to a chain, rope, or wire. Many manual hoists use disk
brakes called Weston-style brakes that 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 the load as it is lowered. Manual hoists also may use ratchets
instead of brakes to secure and control the load. Hoists are
commonly suspended from structures by hook or trolley s, and
used in a variety of industries including transportation,
construction, manufacturing, mining, plumbing, foundry, and
material handling.
Load 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 capacity. 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.
