REPAIR/REPLACEMENT POLICY
All Prostar Electric Chain Hoists are inspected and
performance tested prior to shipment. If any properly
maintained hoist develops a performance problem, due to a
material or workmanship defect, as verified by the factory,
repair or replacement of the unit will be made to the original
purchaser without charge. This repair/replacement policy
applies only to Prostar Hoists installed, maintained and
operated as outlined in this manual, and specifically
excludes hoists subject to normal wear, abuse, improper
installation, improper or inadequate maintenance, hostile
environmental effects and unauthorized
repairs/modifications.
We reserve the right to change materials or design if, in our
opinion, such changes will improve our product. Abuse,
repair by an unauthorized person, or use of non-factory
replacement parts voids the guarantee and could lead to
dangerous operation. All Prostar Electric Chain Hoists are
backed with a lifetime warranty. Refer to the back cover for
details and limitations.
ACCESSORIES
Chain Container
This accessory item (Figure 1A) is used to hold the slack
chain and it is supplied with mounting hardware and
instructions. Chain containers are recommended for those
applications where slack chain will interfere with the load or
drag on the floor as may more often be the case with the
Double-reeved units. Chain containers are shipped
separately and can be furnished for units already in service.
Latchlok ® Hooks
Latchlok Hooks (Figure 1B) are available to replace the
standard lower latch type hooks. The unique design of the
Latchlok Hook assures that it will stay locked until the
operator releases it by depressing the release button. It will
not open accidentally–even if the load chain goes slack.
Once opened, it can be shut with one hand or the weight of
the load when it is lifted. Latchlok Hooks can be supplied
with the hoist or they can be provided in kit form for hoists
already in service.
The Prostar Electric Chain Hoist is a highly versatile
materials handling device that can be used to lift loads that
are within its rated load capacity. It is available in six load
ratings.
