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

Singapore Standards eShop

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

1. Crane Manufacturers/ DL vendors can make an application for

the approval by submitting the below listed documents in a CD

format to OSHD

a A completed application form

b Operational manual for the data logger

c Sample report generated from the data logger

2. Upon receipt of the completed application, an inspector from

OSHD may request for a demonstration of the functionality of

the data logger to be carried out.

3. Once the Ministry is satisfied with the assessment, a letter of

successful application will be issued by the Department. The

list of approved data loggers will be published on the WSH

Councils website.
