The hoist must be used with a control system that meets local electrical safety regulations.
The operational parameters do not allow, but are not limited to:
-
exceeding the defined load capacity
-
any lateral load to be applied the hoist body
-
any side pull to be applied the lift chain
-
heaving, pulling or dragging the load
-
standing beneath suspended and/or lifted loads
-
transporting excessive loads
-
pulling on the control cable
-
failing to observe the load hook constantly
-
failing to observe the load constantly
-
running the chain over edges
-
slack chain to occur which may cause the load to fall
-
use at temperatures below -10° C or above +40° C
-
use in an explosive environment.
Bumping operations shall be limited; ground mooring and driving against the limit switches should be
avoided. The manufacturer accepts no responsibility for damage to equipment and third parties ensuing from
such action.
Special attention shall be taken when hoists are used in or near aggressive environments (e.g. Salt water or
chloroform ). The aluminum and steel alloys used might not be particularly suitable for such environments.
Special attention to protect the chain shall be taken. A high level of lubricant as well as a proper condition of
the zinc layer helps to prevent the chain from becoming corroded. Do not allow anyone under 18 years of
age to operate the chain hoist.In addition to the instructions mentioned in this manual, the user must follow
the rules on accident prevention and safety that are in force in the country where the hoist is being used.
Follow these operating instructions:
Only competent persons are permitted to use the equipment. Make sure you are adequately trained.
Know your load before lifting! Make sure all loads exposed are considered. For example but not limited
to; Self-weight of the load to be lifted, Self-weight of the lifting equipment, the dynamic factor caused
by start and stopping of the hoist, point of gravity of the load and environmental influences such as
wind.
When preparing to lift a load, be sure that the attachments to the hook are firmly seated in hook
saddle. Avoid off centre loading of any kind, especially loading on the point of the hook.
Before lifting, check for twists in the load chain. On single reeved chain hoist used in conjunction with
head blocks and ground support systems, check for twists between the hoist and head block. Twisted
load can result in a jammed chain and damage to the hoist.
On double reeved units a twist can occur if the lower hook block has been upturned between the
strands of chain. The hook should be reversed to remove the twist from the chain before operation.
A safe way of storage in order to avoid turns in the chain is to run the lift hook back to the hoist body,
or secure the hook to a fixing point within its transportation case.
Warn personnel of your intention to lift a load. Make sure the only noise in the area is that of running
hoist. This way abnormalities can be detected easier. Use spotters at required position in order to
observe the lift.
In the event of any abnormal sound coming from the hoist, lifting should be ceased immediately and
the noise investigated by a competent person.
