It is the owner's responsibility to ensure that the product is used according to the duty group that
it has been designed for. By doing so, the product should reach the original predicted lifetime.
DANGER
D0 NOT ALLOW THE PRODUCT TO BE USED OUTSIDE THE LIMITS OF
THE SPECIFIED DUTY GROUP. DOING SO RAISES THE RISK OF
MECHANICAL
FAILURE AND CAN SHORTEN THE PRODUCT'S LIFETIME
The duty group is based on many factors including the hardware, the predicted lifetime, the
number of shifts and lifts, the distances traveled, the ratio of heavy to light items lifted and the
environmental conditions the product is used in. Notice that, if you moved from single-shift
working to three-shift working, you would need to reduce the loads or distances lifted and/or
traveled in order to remain within the requirements of the duty group.
Parameter
Variables
Light use and heavy use
Lifting height and working
distances
Actual hoisting time and the average
distances being traveled by the trolley
and lifting devices.
Operating environment
The product is designed to work within
specific parameters of temperature,
humidity and cleanliness.
Product process
The number of shifts.
The number of work cycles per hour and
the average lifted loads.
Authorized service personnel must periodically check whether the product is being used
according to the duty group. Owners and operators should recognize that any changes to
product usage could, if left unchecked, raise overall maintenance costs and considerably
reduce the safe operating lifetime of the product. Changes to any of the parameters and
variables can require the duty group to be revised.
If there will be significant permanent changes in the product usage, authorized service
personnel must revise the duty group and SWP as necessary. Changes to hardware or
servicing frequency may be required.
