Electric hoists are a mechanical unit that is designed
to lift, lower or pull loads. Whether a manually-powered product for
small loads or a heavy duty electrical motor driven version, an electric
hoist can offer a load carrying capacity for companies and individuals,
which no human alone could match. Electric hoists can be operated by
electrical, manual, hydraulic or pneumatic power, but the most commonly
used are electric hoists. Electric hoists are powered by an electrical
motor that helps them lift or lower a load to a designated location.
These types of electric hoists are typically mounted in one of three
arrangements: lug, trolley or suspension mountings. For consumers who
desire something besides off-the-shelf mounts, many companies additionally
offer custom mounting configurations.
A common type of electric hoist is a chain electric hoist, which uses
a linked or roller chain to lift and lower loads. Chain electric hoists
are sturdy and can be advantageous because they are fairly inexpensive,
simple to operate, generally rust-resistant and low maintenance. Additionally,
these electric hoists are flexible and have the ability to withstand
high temperatures and other less desirable environments. An alternative
to a chain hoist is a wire rope hoist, which uses wire
rope instead of chains to transport materials. These types of electric
hoists can be used in various positions, either stationary or as a mobile
unit attached to a trolley system. Other types of electric hoists are
available for very specific applications, such as those used to remove
engines from airplanes and automobiles, and those that help operate
the gates of dams.
Because of the wide variety of materials and products that can be transported
using electric hoists, winches and cranes, many different industries
are able to benefit from these machines. An electric hoist can be used
to move and handle large rolls of paper to install in printing presses,
so that newspapers can be printed daily. In the food industry, electric
hoists are capable of moving large equipment that is used for the mixing
of ingredients and containers for storage. Electric hoists of this type
are generally made for the particular environment and can be very gentle,
depending on need. In mining applications, electric hoists are especially
useful for withdrawing shield support and mounting platforms from mines.
These electric hoists tend to be highly durable hoists that are able
to withstand the rough environment, plus they tend to be explosion proof.
When considering electric hoists, it is important to consider the application
for which it will be used. Maximum weight capacity, maximum lift speed,
line type and mounting type of the electric hoists need to be taken
into account as well. These are important considerations because, for
instance, buying a casual load lifting hoist to transport a boat would
be disastrous. Using a lighter load hoist would result in damage to
the hoist and/or boat, not to mention the safety issues it would raise
for the employees. Safety must be taken into account when using electric
hoists to ensure that the weight of the objects being raised or lowered
does not surpass the maximum load carrying capability. Injuries can
happen when dealing with this kind of equipment, so one must understand
how to safely operate these electric hoists machines before use in order
to avoid harm.
Types of Electric Hoists
Auxiliary hoists
are supplemental hoists that are used to handle light loads at a higher
speed than the main hoist.
Boat hoists
are lifting units specially designed to raise and lower boats. Boat
hoists are typically hydraulically or electrically powered and can lift
up to 20,000 pounds.
Chain hoists
use roller or link chains as a lifting medium. Chain hoists are typically
electrically powered, but can be manually and pneumatically operated
as well.
Engine hoists
are lifting units designed to allow engine removal from automobiles,
airplanes or boats. Engine hoists are typically hydraulically powered,
but sometimes use an electrical motor.
Gate hoists
are exclusively used to lift the water controlling gates at dams.
Wire rope hoists
use wire rope as a raising/lowering medium. A complete wire rope hoist
consists of a rope storage drum, one or more motors, a gear box
and
a braking system; they can be mounted in a stationary position or along
a monorail attached to a trolley that allows them to slide to different
locations.
Electric Hoists Terms
Attachments –
Components that are used along with lifting devices, forged, stamped or
cast.
Boom (Crane) – The projecting
part of a hoist, sometimes connected to a rotating structure. This is
responsible for supporting the hoisting tackle and load.
Breaking Strength – The measured
load that is required to break a chain or wire rope.
Carbon Chain – A type of chain
commonly used for various pulling and towing purposes.
Clevis – A U-shaped fitting
that has a pin or a number of pins. A shackle clevis is a device used
to safely lift a load.
Controller – A device used by
the hoist operator to adjust the amount of power delivered to the unit’s
electrical motor.
Critical Load – The load point
at which any uncontrolled movement will result in hazardous safety conditions.
Critical Service – Using hoisting
equipment for the handling of critical items.
Cushioned Start – A way of reducing
the rate of acceleration when moving loads.
Drum – A cylindrically-shaped
barrel with a uniform diameter that can be found in grooved or smooth
configurations. Wire
rope or chain is wound around the drum for operation and storage.
Festooning – A way of supplying
power to a hoist that is moving along a beam.
Hook – A lifting attachment
that is connected to a hoist.
Hook Load – The total weight
that is supported by the hook of a hoist. This includes the load, wire
or rope tackle and any other masses suspended from the hook.
Idler – A roller that is used
to support and guide a rope or chain.
Lifters – Grabs that are designed
to attach, hold, control and direct a load, commonly used with hoists.
Line Speed – A measure of the
quickness of a hoist to wind up or let out its lifting/lowering medium.
Line speed is typically measured by the manufacturer without a load attached
to the hoist.
Load Capacity – The maximum
weight that a hoist is designed to safely carry. Under full loads a hoist’s
maximum line speed is typically reduced.
Pawl – The device that acts
directly upon the ratchet. The pawl ensures the one way travel of the
ratchet, which adds safety in case the raising/lowering force is suddenly
withdrawn.
Plate Clamps – Devices that
are used with hoists to lift large, heavy steel plates.
Qualified Inspector – A professional
or manufacturing representative who is certified to inspect a hoist or
other type of rigging system.
Ratchet – A circular-shaped
mechanism with uniform ridges. The ratchet allows for line retrieval of
intake.
Reeving – The path of the wire
rope on a hoist when it pays off the hoist drum and wraps around the upper
and lower sheaves.
Rigging – Any necessary equipment
or hardware used to attach a load to a hoist.
Running Sheave – A sheave that
will rotate when the hook is raised and lowered.
Side Pull – The portion of the
hoist’s pull that is acting horizontally when hoist lines are not
acting vertically.
Sheave – The grooved wheel/pulley
that uses a chain or a rope to change the direction and point of application
of the pulling force.
Tag Line – A type of rope used
to avoid load rotation.
Trolley – A wheeled mechanism
supported by a frame from which the hoist is suspended. The trolley allows
for movement of the hoist for transporting supported loads.
Winch – A lifting device, which
consists of a horizontal cylinder on a wire rope or chain, wound by a
crank.
