Harrington LB Lever Hoist, Hook Mount, 2-3/4 Ton Capacity, 10' Lift

Description

Harrington LB Lever Hoist, Hook Mount, 2-3/4 Ton Capacity, 10' Lift
Load Capacity:5500 pounds | Pull Force:81 Pounds | Headroom String:14.8 Inches
| Lever length:10.4 inches | Hook Opening String:1.4 Inches | Maximum lifting
height:10 Feet The Harrington LB lever hoist with hook mount 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 mount 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 mount hook and load
hook resist fracture under stress. The mount 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 amounts 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 mounts, 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 amount 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 amount 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.
