Dear Shareholder:

The Board of  Directors  of Columbus  McKinnon  Corporation  has  announced  the
adoption of a  Shareholders  Rights  Plan.  The Plan  provides for a dividend of
Rights to  purchase  shares of a new series of  Preferred  Stock (or, in certain
circumstances,  Common  Stock  or  other  consideration),  exercisable  upon the
occurrence of certain events.

We believe that the Plan protects  your  interests in the event that the Company
is  confronted  with  coercive or unfair  takeover  tactics.  The Plan  contains
provisions  to protect you in the event of an  unsolicited  offer to acquire the
Company. Although we are not aware of any such potential offers, the Plan offers
protection from offers that do not treat all shareholders equally,  acquisitions
in the open market of shares constituting control without offering fair value to
all shareholders and other coercive or unfair takeover tactics that could impair
the Board's ability to represent your interests fully.

The Plan will not  affect an offer at a fair  price  and  otherwise  in the best
interests  of the Company and its  shareholders  as  determined  by its Board of
Directors.  The Rights Plan will not interfere  with a merger or other  business
combination  transaction  that the Board of  Directors  approves  as fair and as
constituting a recognition of full value to the shareholders.

The Rights would become  exercisable to purchase  shares of Preferred Stock (or,
in certain  circumstances,  Common  Stock) only if (i) a person  acquired 15% or
more of the Company's Common Stock, (ii) a person commenced a tender or exchange
offer  for 15% or more of the  Company's  Common  Stock,  or (iii)  the Board of
Directors  determined that the beneficial owner of at least 15% of the Company's
Common Stock intended to cause the Company to take certain actions adverse to it
and its shareholders or that such ownership would have a material adverse effect
on the  Company.  In  circumstances  described  in clauses (i) and (iii)  above,
holders of Rights  would be entitled to purchase,  in lieu of  Preferred  Stock,
Common Stock of the Company at a 50% discount  from market value.  Moreover,  in
the event  that the  Company  were to enter  into  certain  merger or asset sale
transactions,  after the occurrence of circumstances described in clauses (i) or
(iii),  holders would be entitled to exercise the Rights for common stock of the
acquiring entity.













The acquiring or adverse persons described in clauses (i) and (iii) would not be
entitled to exercise Rights.

The issuance of Rights does not in any way weaken the financial  strength of the
Company or interfere with its business plans.  The issuance of the Rights has no
dilutive effect, will not affect reported earnings per share and will not change
the way in which you can currently trade shares of the Company's Common Stock.

A summary of the Plan is enclosed.  The Plan is complex, and we
urge you to read this summary carefully.  Its premise, however, is
straightforward: to serve and protect the interests of the
Company's shareholders.


                                           Sincerely,




                                           
                                           Herbert P. Ladds, Jr.,
                                           President and Chief Executive Officer





November 10, 1997.

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK


         On October  25,  1997,  the Board of  Directors  of  Columbus  McKinnon
Corporation  (the  "Company")   declared  a  dividend  of  one  Right  for  each
outstanding  share of the Company's  Common Stock, par value $.01 per share (the
"Common Stock"),  to shareholders of record at the close of business on November
10, 1997. Each Right entitles the registered holder to purchase from the Company
a  unit  consisting  of  one  one-hundredth  of  a  share  of  Series  A  Junior
Participating  Preferred  Stock,  par  value  $1.00 per  share  (the  "Preferred
Stock"), at a Purchase Price of $80.00 per unit of one one-hundredth of a share,
subject to adjustment.  The description and terms of the Rights are set forth in
a Rights  Agreement  (the "Rights  Agreement")  between the Company and American
Stock Transfer & Trust Company, as Rights Agent.

         Initially, the Rights will be attached to all Common Stock certificates
representing  shares then outstanding,  and no separate Rights Certificates will
be distributed. A Distribution Date will occur and the Rights will separate from
the  Common  Stock  upon  the  earliest  of (i)  ten  days  following  a  public
announcement  that a Person or group of  affiliated  or  associated  Persons (an
"Acquiring Person") has acquired,  or obtained the right to acquire,  beneficial
ownership  of 15% or more of the shares of Common Stock then  outstanding1  (the
"Stock Acquisition  Date"), (ii) ten business days following the commencement of
a tender  offer  or  exchange  offer  that  would  result  in a Person  or group
beneficially  owning  15% or more of such  outstanding  shares of  Common  Stock
(unless  such  tender  offer or exchange  offer is an offer for all  outstanding
shares of Common Stock which a majority of the  unaffiliated  Directors  who are
not officers of the Company  determine  to be fair to and  otherwise in the best
interests  of the Company and its  shareholders)  or (iii) the date the Board of
Directors  declares a person to be an "Adverse Person",  upon a determination by
the Board that such Person,  together with his affiliates or  associates,  is or
has become  the  beneficial  owner of 15% or more of the shares of Common  Stock
outstanding,  and upon a determination  by at least a majority of the Continuing
Directors  (as  defined  below)  who  are not  officers  of the  Company,  after
reasonable inquiry and investigation,  including  consultation with such persons
as such Directors shall deem
- - --------
1 Under the Rights Agreement,  for purposes of calculating percentages of Common
Stock  outstanding,  shares of Common Stock outstanding shall include all shares
of Common Stock deemed to be  beneficially  owned by a person and its affiliates
and associates, even if not actually then outstanding.






appropriate,  that (a) such  beneficial  ownership by such person is intended to
cause the Company to  repurchase  the Common  Stock  beneficially  owned by such
person or to cause  pressure  on the  Company  to take  action  or enter  into a
transaction  or series of  transactions  intended  to provide  such  person with
short-term  financial gain under circumstances  where such Continuing  Directors
determine that the best long-term  interests of the Company and its shareholders
would not be served by taking such action or entering into such  transactions or
series of transactions at that time, or (b) such beneficial ownership is causing
or reasonably  likely to cause a material  adverse  impact  (including,  but not
limited to,  impairment  of  relationships  with  customers,  impairment  of the
Company's  ability to maintain its  competitive  position or  impairment  of the
Company's business reputation or ability to deal with governmental  agencies) on
the business or prospects of the Company.

         Until the  Distribution  Date,  (i) the Rights will be evidenced by the
Common Stock certificates and will be transferred with and only with such Common
Stock certificates, (ii) new Common Stock certificates issued after November 10,
1997 will contain a notation  incorporating  the Rights  Agreement by reference,
and (iii) the  surrender  for  transfer  of any  certificates  for Common  Stock
outstanding will also constitute the transfer of the Rights  associated with the
Common Stock represented by such certificate.

         The Rights are not  exercisable  until the  Distribution  Date and will
expire at the close of business on November 10, 2007, unless earlier redeemed by
the Company as described below.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to  holders  of  record  of the  Common  Stock as of the close of
business  on  the  Distribution  Date  and,  thereafter,   the  separate  Rights
Certificates alone will represent the Rights. Except (i) with respect to certain
shares of Common Stock issued or sold  pursuant to the exercise of stock options
or under any employee plan or arrangement,  or upon the exercise,  conversion or
exchange of certain securities of the Company,  or (ii) as otherwise  determined
by the Board of  Directors,  only  shares of Common  Stock  issued  prior to the
Distribution Date will be issued with Rights.

         In the event that (i) a Person becomes the  beneficial  owner of 15% or
more of the then outstanding shares of Common Stock (except pursuant to an offer
for all outstanding shares of Common Stock which a majority of the Directors who
are not officers of the Company and who are not affiliates or associates of such
Person  determine  to be fair to and  otherwise  in the  best  interests  of the
Company and its shareholders), or (ii) the Board of Directors declares, upon the
determination  by at least a majority of the  Continuing  Directors  who are not
officers of the

                                        2





Company,  that a person is an  Adverse  Person  (each  such  event,  a  "Flip-in
Event"),  each holder of a Right will thereafter have the right to receive, upon
payment of the Purchase Price, Common Stock (or, in certain circumstances, cash,
property or other  securities of the Company) having a value (based on a formula
set forth in the Rights  Agreement) equal to two times the Purchase Price of the
Right.  Notwithstanding  any of the  foregoing,  following the occurrence of the
Flip-in Event, all Rights that are, or (under certain circumstances specified in
the Rights  Agreement)  were,  beneficially  owned by an Acquiring  Person or an
Adverse Person (or by certain related  parties) will be null and void.  However,
Rights are not  exercisable  following the occurrence of the Flip-in Event until
such time as the Rights  are no longer  redeemable  by the  Company as set forth
below.

         For example,  at a Purchase  Price of $80.00 per Right,  each Right not
owned by an Acquiring Person (or by certain related parties) following a Flip-in
Event would  entitle its holder to purchase  $160.00  worth of Common  Stock (or
other consideration,  as noted above) determined pursuant to a formula set forth
in the Rights  Agreement,  for $80.00.  Assuming that the Common Stock had a per
share value of $20.00 at such time (as determined pursuant to such formula), the
holder of each valid Right  would be  entitled  to purchase  eight (8) shares of
Common Stock for $80.00.

         In the event that, at any time following the Stock  Acquisition Date or
the  date on which a Person  is  determined  to be an  Adverse  Person,  (i) the
Company is acquired in a merger or other  business  combination  transaction  in
which  the  Company  is not the  surviving  corporation  or in  which  it is the
surviving corporation but its Common Stock is changed or exchanged (other than a
merger meeting  certain  conditions  which follows an offer for all  outstanding
shares of Common Stock which a majority of the  unaffiliated  Directors  who are
not officers of the Company  determine  to be fair to and  otherwise in the best
interests  of the  Company  and its  shareholders),  or (ii)  50% or more of the
Company's assets, earning power or cash flow is sold or transferred, each holder
of a Right (except Rights which  previously have been voided as set forth above)
shall thereafter have the right to receive,  upon payment of the Purchase Price,
common  stock of the  acquiring  company  having a value  equal to two times the
exercise  price of the Right.  The events  set forth in this  paragraph  and the
Flip-in Events  described in the second  preceding  paragraph are referred to as
the "Triggering Events."

         The  Purchase   Price   payable,   and  the  number  of  units  of  one
one-hundredths  of a share of Preferred  Stock or other  securities  or property
issuable,  upon  exercise of the Rights are subject to  adjustment  from time to
time  to  prevent  dilution  (i) in the  event  of a  stock  dividend  on,  or a
subdivision,  combination or  reclassification  of, the Preferred Stock, (ii) if
holders of the Preferred Stock are granted certain rights or warrants to

                                        3





subscribe for Preferred Stock or convertible securities at less than the current
market price of the Preferred  Stock, or (iii) upon the  distribution to holders
of the Preferred Stock of evidences of  indebtedness  or assets  (excluding cash
dividends  not in excess of 200% of  regular  quarterly  cash  dividends)  or of
subscription rights or warrants (other than those referred to above).

         With certain  exceptions,  no adjustment in the Purchase  Price will be
required  until  cumulative  adjustments  amount to at least 1% of the  Purchase
Price.  No  fractional  shares of Preferred  Stock (other than  fractions of one
one-hundredth of a share, or integral  multiples thereof) will be issued and, in
lieu  thereof,  an  adjustment in cash will be made based on the market price of
the Preferred Stock on the last trading date prior to the date of exercise.

         At any time until ten days  following the Stock  Acquisition  Date, the
Company may redeem the Rights in whole,  but not in part, at a price of $.01 per
Right (payable in cash, Common Stock or other  consideration  deemed appropriate
by the Board of Directors).  Under certain circumstances set forth in the Rights
Agreement, the decision to redeem shall require the concurrence of a majority of
the  Continuing  Directors who are not officers of the Company.  The Company may
not redeem the Rights if the Board of Directors has previously declared a Person
to be an Adverse Person.  Immediately  upon the action of the Board of Directors
ordering redemption of the Rights, with, where required, the concurrence of such
Continuing  Directors,  the  Rights  will  terminate  and the only  right of the
holders of Rights will be to receive the $.01 redemption price.

         The  term  "Continuing  Director"  means  any  member  of the  Board of
Directors  of the Company who was a member of the Board prior to the date of the
Rights  Agreement,  and any Person who is  subsequently  elected to the Board if
such  Person  is  recommended  or  approved  by a  majority  of  the  Continuing
Directors,  but shall not include an Acquiring  Person,  an Adverse Person or an
affiliate or associate of any such Person,  or any  representative of any of the
foregoing.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive  dividends.  While the distribution of the Rights will not
be taxable to shareholders or to the Company,  shareholders may,  depending upon
the circumstances,  recognize taxable income in the event that the Rights become
exercisable  for Common  Stock (or other  consideration)  of the  Company or for
common stock of the  acquiring  company as set forth  above,  or are redeemed as
provided in the second preceding paragraph.


                                        4




         Other than certain provisions  relating to the principal economic terms
of the Rights,  any of the provisions of the Rights  Agreement may be amended by
the Board of Directors of the Company prior to the Distribution  Date. After the
Distribution  Date, the provisions of the Rights Agreement may be amended by the
Board  (in  certain  circumstances,  with  the  concurrence  of  the  Continuing
Directors)  in  order  to cure  any  ambiguity,  to make  changes  which  do not
adversely  affect the  interests  of holders of Rights  (other than an Acquiring
Person, an Adverse Person or an affiliate or associate  thereof),  or to shorten
or lengthen any time period under the Rights Agreement;  provided, however, that
no amendment  to adjust the time period  governing  redemption  shall be made at
such time as the Rights are not redeemable.

         The Rights have certain anti-takeover  effects.  Exercise of the Rights
will cause  substantial  dilution to a Person or group that  attempts to acquire
the  Company on terms not  approved by the  Company's  Board of  Directors.  The
existence  of  Rights,  however,  should not affect an offer at a fair price and
otherwise  in the  best  interests  of  the  Company  and  its  shareholders  as
determined by the Board of Directors.  The Rights should not interfere  with any
merger or other business  combination  approved by the Board of Directors  since
the Board of Directors may, at its option,  at any time until ten days following
the  Stock  Acquisition  Date or until a Person  has  been  determined  to be an
Adverse Person redeem all but not less than all of the then  outstanding  Rights
at the $.01 redemption price.

         A copy of the Rights  Agreement has been filed with the  Securities and
Exchange  Commission  as an Exhibit to a  Registration  Statement on Form 8-A. A
copy of the Rights Agreement is available free of charge from the Company.  This
summary  description  of the  Rights  does not  purport  to be  complete  and is
qualified  in its  entirety  by  reference  to the  Rights  Agreement,  which is
incorporated herein by reference.
