Tips to lift hoist sales
by Robert Olson
Hoists play a vital role in the
manufacturing environment, lifting materials and moving finished products from
one location to another. Selecting
the right hoist from among hundreds
of types and options can be an overwhelming decision for the plant manager. Your ability to help the plant manager choose the proper hoist for his or
her
particular application adds value to your role as a
distributor and increases the confidence your customers have in you.
Before you meet with a customer, become comfortable with
the jargon of the industry. A simple glossary of terms includes:
Capacity - The maximum
load a hoist is designed to lift or pull. Capacity is commonly expressed in
Tons.
Chain Fall Lines or Reeves
- The number of lines of chain or wire rope between the hoist body and the
bottom hook.
Crane - A mechanism used
to lift and lower loads
and capable of moving in both horizontal directions.
Headroom - The distance
between the top and
bottom hooks of a hoist.
Hoist - A manually or
electrically operated
mechanism that lifts and lowers a suspended load.
Lift - The maximum
distance the bottom hook
can travel.
Sheave - A pulley or
sprocket used with a chain or wire rope hoist.
Suspender - A
load-bearing component designed to connect a hoist to a trolley.
Trolley - A mechanical
device with wheels that
travels on a beam and carries the hoist.
Hoist basics
Hoists are available in two basic designs, chain or
wire rope. Either design comes in
manual, electric and air-powered models that offer distinct advantages to the
user depending upon the specific application.
Matching the application to the appropriate hoist is the
first step in the selection process. As
you begin
to work with a customer to clearly define the hoist
application, it’s a good idea to include the following questions in your
dialog:
How much will the load
weigh? The largest load the hoist will handle, as well as the weight
of any attachments that facilitate the handling of loads – things like slings,
grabs, spreader beams, vacuum lifts and manipulators – need to be carefully
considered as you define the hoist’s capacity. Carefully match these loads to the tonnage capacities of the hoists you
are considering. A hoist that is
under- or over-rated in terms of capacity required introduces inefficiencies as
well as safety issues into the material handling system.
How frequently will the hoist be
used? If a hoist will lift and move loads frequently, an electric or pneumatic
hoist is probably the best choice. On the other hand, if the hoist will only be
used occasionally, a hand chain hoist should suffice.
Will the hoist be used solely to lift materials and
equipment? If so, a hoist alone
will perform the task at hand. If,
on the other hand, the hoist will be used to lift and move items horizontally,
you need to suggest one of two hoist combinations: a hoist/trolley system that
will lift and move a load in one direction or axis, or a hoist/crane
system that will lift and provide movement in two
horizontal directions. Both of
these systems increase the versatility of the hoist.
When a trolley is required, select one that correlates with
the frequency of use. A plain or
geared trolley requires the operator to start and stop the movement by hand and
is usually satisfactory for occasional lifts and intermediate loads. Motorized trolleys are the
appropriate choice for more frequent, heavy loads.
When a hoist is paired with a bridge crane system,
the user needs to consider runway structure design and installation when
selecting the proper hoist. Crane
clearances, building load capability, anticipated future use of the crane,
additional controls and electrification should also be part of the
deliberations.
What is the required lift
speed? Lift speed and
positioning capabilities also dictate the type of hoist to recommend for an
application. Traditionally, manual
hoists offered more precise positioning load capabilities because they operate
at slower speeds. However,
today’s advanced electronic controls have enhanced precision, enabling faster
electric and air-powered hoists to meet exact positioning requirements.
What are the electrical requirements of the
hoist? Determine available voltage and whether it is single- or
three-phase. Industrial three-phase power is the preferred choice, because it is more
efficient and there is more equipment from which to choose. Only consider
single-phase hoists if three-phase power is not available.
If the application requires a trolley, the user must
consider how to supply power to the hoist. Additionally, every hoist system needs a power disconnect and
overcurrent protection as specified by the National Electrical Code and OSHA. ANSI and OSHA provide standards that dictate the construction,
inspection, testing, maintenance and operation of individual hoists.
What are the headroom
requirements? The minimum headroom measurements are critical to proper hoist
selection. Hoists can be
trolley-mounted or suspended from a fixed overhead lug or hook. Typically, lug-
mounted hoists have less headroom than hook-mounted models. If the required headroom is even less than that offered by standard
lug-mounted hoists, hook points
can be changed or hoists specially designed with lower headroom.
What type of operator interfaces will be
used? Manual hoists typically have simple-to-use hand chains or levers to
control the action of the hoist. With
electric models there are a multitude of ways to control the hoist. Most commonly a push button station is suspended from the
hoist. Safety concerns may require the operator to stand away from larger, bulky
loads. In this case, the customer
may require a remotely controlled hoist.
Describe the environment in which the hoist will be
used. Working environments that expose a hoist to temperature extremes, heavy
moisture, the outdoors or other
hazardous conditions may limit the selection of hoists available to your
customer.
Ergonomics, too, influence hoist
selection. Manufacturers are beginning to offer hoists that are specifically
designed to address the ergonomic issues
associated with repetitive assembly lines, pick-and-place operations, severe
working environments and work
stations or work cells.
Why are you replacing your current
hoist? It’s always good to know the history of the hoist you are
replacing. By discussing a hoist’s performance record, you may uncover information
that will help you more clearly define the hoist application and avoid problems
associated with poor performance and inefficiencies in the past.
Not every sales call you make will generate an
immediate sale. Sometimes your
objective is to gather information about existing hoists. As you meet with users who may not be considering a hoist replacement,
use the questions that follow as the basis of your conversation. The answers may
suggest to you and to
the user that they do, in fact, need to replace hoists that no longer perform as
efficiently as the newer models
you offer.
• Do you currently use a hoist?
• What brand of hoist do you use?
• How do you use the hoist?
• How does your hoist perform? Have you
experienced problems with it?
• How frequently does your hoist require
maintenance?
• What types of maintenance do you perform?
• Are you responsible for the hoists in your facility?
• Do you specify the hoists that your company uses?
• Do you have any influence on those that
do purchase?
• Is there an expansion or new line that will require
additional hoists?
Questions like these enable you to identify customers’
current and projected needs. In the
process of asking these questions, you may have the opportunity to
connect with other individuals in a facility that are involved with your
products – such as safety directors, maintenance personnel or purchasing
contacts –
increasing your sales opportunities.
Finally, employ the hoist manufacturer’s resources and
customer service capabilities in your sales efforts. Detailed drawings and specifications that go beyond the
standard catalog drawings are often available upon request, as are market
information and responses to
common objections to hoist replacement. Plus,
take advantage of your manufacturer’s sales training programs that provide
updated product information. Frequent
updates position you as a hoist expert, enabling you to meet customer
expectations and avoid the dissatisfaction that accompanies product returns and
failures.
