CHAIN BLOCK
SAFETY OPERATIONS & PARTS MANUAL
CH A IN BL O CK
This manual contains important information to help you properly install,
operate and maintain your 3S chain block for maximum performance,
economy and safety. Please study its contents thoroughly before putting
your chain block into operation. By practicing correct operating procedures
and by carrying out the recommended preventative maintenance
suggestions, you will be assured of long, dependable and safe service.
After you have completely familiarised yourself with the contents of this
manual, we recommend that you carefully file it for future reference.
The information herein is directed to the proper use, care and maintenance
of the 3S chain block and does not comprise a handbook on the broad
subject of rigging. Rigging can be defined as the process of lifting and
moving heavy loads using hoists and other mechanical equipment. Skill
acquired through specialised experience and study is essential to safe
rigging operations. For rigging information, we recommend consulting a
standard textbook on the subject.
UNPACKING
After opening the carton, the chain block should be carefully inspected
for damage which may have occurred during shipment or handling. Check
the chain block frame for dents or cracks and inspect the load chain for
nicks and gouges. If shipping damage has occurred, contact your local
supplier or Beaver Brands Sales Office.
WARNING
Operating a unit with obvious external damage may
cause load to drop and that may result in personal
injury and/or property damage.
TO AVOID INJURY
Carefully check unit for external damage prior to installation.
OPERATING INSTRUCTIONS
After mounting and before
placing in service, check the
chain block for proper operation.
To operate the chain block, pull
on the hand chain as indicated.
Operate the chain block with
no load and then a light load of
approximately 20kg. To make
sure it operates properly and
the brake holds the load when
the hand chain is released, then
operate with a rated load as
shown on the capacity plate.
WARNING
TO AVOID INJURY
Stop operating in the lifting
direction when the hook block
contacts the hoist frame and /
or hanger, as noted by sudden
increase in hand chain pull or
tipping of the hook block.
