Top 5 Contraventions Operation Heron Findings and Results 1. Failure to maintain cranes in good working order 2. Failure to establish and implement a proper Lifting Plan 3.

11 Top 5 Contraventions Operation Heron Findings and Results 1. Failure to maintain cranes in good working order 2. Failure to establish and implement a proper Lifting Plan 3. Failure to ensure that adequate safety measures are taken in respect of any Crane used at the workplace 4. Failure to maintain Lifting Gears in good working condition 5. Failure to implement a proper Permit-To-Work System

12 Failure to maintain Cranes in good working order Misalignment of wire rope on crane winch Safety devices not working Safety latch of auxiliary hook of crawler crane is faulty

13 Failure to maintain Cranes in good working order Inadequate greasing and corrosion of wire ropes on crawler crane Kinked wire ropes

the lifting equipment / lifting gear used Means of communications Personnel involved in the lifting operation

14 Failure to establish and implement a proper Lifting Plan Lifting plan inadequate (generic information) Lifting team do not understand lifting plan The key elements of the lifting plan include: Details of the load Details of the lifting equipment / lifting gear used Means of communications Personnel involved in the lifting operation Physical and environmental considerations Sequence of movement / special precautions Sketch of the zone of operation

15 Failure to Maintain Lifting Gears in Good Working Condition Frayed webbing sling Lifting gear in Poor condition

16 What Needs to be Done? Check cranes (safety devices) Maintenance regime Re-familiarisation for operators Supervision Crane Owners Operators Daily checks Report of unsafe equipment / operation Thorough and proper inspection Use of checklist Authorised Examiners Occupiers Competency of lifting team Crane safety mgmt system

17 Safe use of Cranes Sharing of Industry Practices MOM in collaboration with NCSTF (WSH Council) is embarking on a study to learn industry practices in managing the safe use of mobile cranes Main Factors 1. Lifting Equipment 2. Lifting Personnel 3. Lifting Operation

19 Safe use of Cranes Sharing of Industry Practices Compulsory In-house training and test for contractors One lifting supervisor for one crane Appointment of Lifting Engineer to oversee all lifting activities Regular drugs and alcohol tests for safety critical roles Personnel

Safe use of Cranes Sharing of Industry Practices Classification of lifts such that more stringent requirements are applied for critical lifts such as additional load testing of crane Develop

20 Safe use of Cranes Sharing of Industry Practices Classification of lifts such that more stringent requirements are applied for critical lifts such as additional load testing of crane Develop emergency response / contingency plans for critical processes within collapse zone Regular review of lifting data (data logger) for early intervention Lifting Operation Additional safety factor for apparent weight of load Proper planning - Submission of proper documents including lifting plans 24 hrs prior to bringing cranes on site

21 Data Loggers Benefits Records key operational parameters Allow retrieval of data to review and monitor the lifting operations. Take proactive intervention programme to prevent any unsafe operations Aid in the investigations of crane-related incidents

22 Data Loggers Implementation Plan Effective date of implementation: All mobile cranes registered with MOM on or after 1 August 2015 will have to be equipped with data loggers; and All existing mobile cranes registered before 1 August 2015, will be required to be retrofitted with data loggers by 1 August 2018.

23 Data Loggers Requirements Examples of types of mobile cranes required to be installed with DLs 601- Mobile Crane - Truck Mounted Variable Boom Length Type 602- Mobile Crane - Truck Mounted Fixed Boom Length Type 611- Mobile Crane - Crawler Mounted Variable Boom Length Type 612- Mobile Crane - Crawler Mounted Fixed Boom Length Type 621- Mobile Crane - Wheel Mounted (w/o prime mover) Variable Boom Length Type 622- Mobile Crane - Wheel Mounted (w/o prime mover) Fixed Boom Length Type 651- Mobile Tower Crane (Horizontal Boom) 652- Mobile Tower Crane (Luffing Boom) 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 The diagrams/figures are reproduce from Annex A of SS 536 : 2008 with the permission of SPRING Singapore. Singapore Standards are available from the Singapore Standards eshop

24 Co-Funding Scheme for Existing Mobile Cranes Funding Assistance to support existing fleet of MC 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 serve basis and it will cease on the 31 July 2018 or when the funds have been fully disbursed.

25 Co-Funding Scheme for Existing Mobile Cranes Eligibility Criteria Mobile Crane is registered with MOM before 1 Aug 2015; Has more than 3 years of remaining lifespan; Installed with a Data Loggers listed on WSH Council website; Listed as one of the following mobile crane types (601, 602, 611, 612, 621, 622, 651 and 652). Design safe working load (Maximum Capacity) Maximum allowable years of service from the year of manufacturing 50 tons and below 20 Above 50 Tons but not more than 100 Tons Tons and above 30

Co-Funding Manufactures Scheme role for Existing Mobile Cranes Application process for the Data Logger Fund MOM Crane Owners Crane Manufacturer Authorised Examiner WSHC Crane manufacturers / DL

26 Co-Funding Manufactures Scheme role for Existing Mobile Cranes Application process for the Data Logger Fund MOM Crane Owners Crane Manufacturer Authorised Examiner WSHC Crane manufacturers / DL vendors can apply with MOM to conduct an assessment for the data loggers to be eligible for funding Engages crane manufacturer/ DL vendor to install eligible DL on the existing Mobile Cranes Manufacturer/ DL vendor proceeds to install DL on crane AE inspects crane to verify that DL installed is according to MOMs requirements Crane owners can make the fund application on ataloggerfund. If the application is in order, funds will be disbursed up to 50% or $5000 per crane whichever is lesser

27 Co-Funding Scheme for Existing Mobile Cranes Requirement for Approval (For Crane Manufacturers/ DL Vendors) 1. Crane Manufacturers/ DL vendors can make an application for the approval by submitting the below listed documents in a CD format to OSHD Documents to be submitted (in CD format): 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.
