1.5. Technical status

1.5.1. Periodic checks

Each device/ unit operator should adequately note all checks,
maintenance and inspections performed in the log book, and have these
confirmed by the competent person in charge.
Incorrect or missing entries will lead to forfeiture of the manufacturer's

warranty.

CAUTION!
Equipment and cranes should be periodically tested by an expert.
Basically, visual and functional checks should be performed to
determine the condition of components as regards damage, wear,
corrosion or other modifications. In addition, safety equipment is
assessed for completeness and efficiency. It may be necessary
to dismantle the equipment under inspection to correctly assess
expendable parts.
CAUTION!
Suspension apparatus must be inspected over its entire length,
including covered or hidden parts.
CAUTION!
All periodical inspections should be arranged by the operator.
1.5.2. Warranty
– The warranty is void if the installation, operation, testing or maintenance
is not carried out according to these instructions.
– Troubleshooting and repair under warranty may only be carried out by
qualified persons and only after consultation and agreement with the
manufacturer / supplier. Any modifications to the product or the use of
non-original replacement parts will void the warranty.

1.6. Operational parameters

Electric chain hoists of the series TT are hoists of differing load capacities.
They can be installed as stationary or mobile units. Electric chain hoists
are manufactured in accordance with the latest technical developments
and recognised safety standards, and are tested for safe operation by
the manufacturer.
Electric chain hoists are approved by various international institutes such
as BG and others.
Electric chain hoists of the above series may only be used when in
an acceptable technical condition, in accordance with their operating
parameters, by trained personnel in a safe and responsible manner.
We recommend to equip tralift™ TT chain hoists working outdoors
with a protective cover against the effects of the weather or to keep
the chain, trolley and drive under a protection cover when not in use.
Special operating conditions can be agreed in individual cases with the
manufacturer. After consultation, appropriate, optimized equipment,
and important information for safe, low-wear use can be supplied.
The intended use of the electric chain hoist likewise assumes the
adherence to the operating, maintenance and servicing prescribed by
the manufacturer.
Improper use comprises:
– exceeding the defined maximum permissible load capacity;
– pulling the load diagonally (maximum angle 4°, see Figure 1-6);
– heaving, pulling or dragging the load;
– transporting persons;
– transporting loads when personnel are underneath;
– standing under suspended loads (see Figure 1-7);
– puling on the control cable;
– failing to observe the load hook constantly;
– running the chain over edges;
– allowing the load to fall due to a slack chain;
– use in an explosive environment.

Inching operations, 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.
