How
to find the best hoist for you
This
independent guide was created to help you understand
the basics of hoists and to help you choose the right
hoist for you. We do not sell any hoist products or
services ourselves, so you can be confident that all
of the information in this guide is independent and
unbiased.
Background
on hoists
Hoists are created and built to efficiently and ergonomically
move, lift, position or secure material, and the right
hoist for the right job will improve the efficiency
and safety of any operation. Hoists can be an integral
part of a good material handling system, and it's important
to select the hoist that works best in a given environment.
Doing research online is a great way to compare multiple
types, brands and models of hoists to make sure you
find what that will work for your environment based
on your desired price range, capacity and other features.
Features
and functions of hoists
Lifting Capacity- To a large degree, your choice of
which hoist to purchase will depend on the lifting capacity
that you want or need. Small, portable hoists generally
start at ¼ ton capacity, while larger, industrial
plant-type hoists can lift 100 tons or more.
Power
Type- One of the most important aspects of a hoist is
the power source that provides the lifting. The most
basic type of hoist is a manual hoist, in which the
lifting is done by a hand chain or lever in conjunction
with a gearing system. There are also hoists that are
powered by electricity and can use either a wire or
chain to lift the material. Finally, there are air or
pneumatic hoists that use compressed air to provide
the lifting force.
Movement/Portability-
Most hoists are designed primarily to lift material
vertically, but many hoists also provide for horizontal
movement as well. Many hoists are portable or can be
attached with hooks, and other hoists attach to trolleys,
which travel horizontally along a bridge girder.
Clearance
and Lift Length- The vertical distance of the lifting
that you want or need in your environment will determine
the length of the hoist chain or wire that is needed
as well as the headroom that is required. Headroom is
defined as the distance between the top and bottom hooks
of the hoist.
Lift
Speed- Measured in feet per minute, lift speed is a
very important component of the efficiency of a material
handling system or process. The greater the speed that
can be handled by the hoist safely, the greater the
time savings will be in the overall lifting process.
