2.5.2 Hoisting machinery designed working period (DWP)
Based on how the hoisting machinery will be used and on the actual hoisting machinery hardware supplied, the
manufacturer will agree the anticipated hoisting machinery lifetime or designed working period (DWP) with the
customer at the time of purchase.
The total lifetime of hoisting machinery consists of one or more Designed Working Period (DWP) where each DWP
typically lasts for around ten years when the equipment is used in accordance with the designed usage. It is
possible for different hoisting machineries on the same crane, for example main and auxiliary, to have a different
DWP. The DWP is the period in which, provided the equipment has been used and maintained in line with the
original expectations, the equipment can be safely operated.
DWP = Designed Working Period
PGO = Predicted General Overhaul
AGO = Actual General Overhaul
T = Time
In practice the lifetime of the equipment can vary due to changes in the environment and usage of the equipment.
For safety, in accordance with the ISO 12482-1 standard, it is important for authorized service personnel to
periodically check the equipment duty group and operating conditions regularly for any changes, then to revise the
remaining DWP% upwards or downwards accordingly. This action ensures that the equipment is kept operating for
as long as it is safely possible before a General Overhaul must be conducted.
2.5.3 How to assess hoisting machinery designed working period
The hoist service organization assesses the hoisting machinery Designed Working Period, but this table briefly
describes how it is done.
Product
Method
Product equipped with hour counter and log book
The remaining DWP% must be calculated in accordance with the ISO 12482-1 standard,
using the formula presented in the Appendix Designed working period (DWP)
Calculation.

2.6.1 Duty group
When the product is designed and purchased, the predicted lifetime of the product is agreed, based on the
expected use of the product. This expected use is known as the duty group. Hoisting machinery which is used
continuously to lift heavy loads is clearly in a very different duty group to a product of the same size which is used
occasionally just to lift light loads. While the product is used in accordance with the designed duty group, the
expected lifetime should be reached.
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.
WARNING
Do 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.
DANGER
EXCEEDING THE PRODUCT’S SPECIFIED DUTY GROUP COMBINED WITH THE
LACK OF MAINTENANCE CAN LEAD TO A RISK OF A CATASTROPHIC
FAILURE.
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 DWP as necessary. Changes to hardware or servicing frequency may be required.
