Note:1. This classification refers to MOM’s classification
codes for lifting machines
2. Lifting machines under the above classification codes that does not require the installation of a load radius indicator (LRI) will be exempted from the data logger requirements

1. The data logger must be able to perform functions and record operational
parameters specified in the following paragraphs.
2. Requirement on Data Logger Functions
The table below summarises the functions that have to be performed by the data
logger.
S/N Specific Features of Data Loggers
Data LoggersData LoggersData LoggersData LoggersRequirementsRequirementsRequirementsRequirements
1 Detect and record any override key activation for the cranes safety devices
(i.e. over-derricking limiter, over-hoisting limiter and rated capacity limiter)
2 Detect and record overloading occurrences (i.e. when load reaches and
exceeds 100% of the cranes rated capacity)
3 Equip with data security and anti-tampering feature
4 Download recorded data
5 Generates reports
3. Requirement on Operational Parameters to be Recorded
The table below summarises the operational parameters that must be recorded by the
data logger.

4. Other requirements
i. The data logger must be automatically switched on and operational whenever the
mobile crane is in operation.
ii. The data logger must be synchronised with the mobile crane as an integrated
system without safety implications, undue limitations and or restrictions to the
crane operation.

iii. Data from the data logger shall be downloadable by interested parties, such as
crane owners or occupiers, on a regular basis. The report generated shall be in a
readable format that is easily comprehensible.
WSH Council will launch a co-funding scheme which will cover 50%
of the cost of installation up to $5,000 for each registered crane.
The funding will be available from 3 August 2015 on a first-come-first
