SP14 Contracted Crane Activities

Purpose/Scope:

The planning of crane operations is vital in order to maintain safe operation of all equipment. A number of control methods are required by various parties to successfully manage the hazards associated with mobile cranes.

The numerous accidents that occur with crane activities throughout the construction industry highlights the need for Silverback to implement strict controls such as the requirement for thorough documentation submission, inspection routines, and the operation of mobile cranes by suitably trained and qualified persons.

Procedure:

Silverback and subcontracted personnel are to comply with the relevant provisions of the following procedural requirements and references. The typical hazards addressed by this procedure include:

Hazards Risk (Potential)
  • Crane collapse
  • Falling objects
  • Falls from heights
High

Crane Preparation and Planning

  1. The requirements and planning for location of a crane on site is to be considered as early as possible in the development of each project, particularly in determining operating and working load limits.
  2. Following this initial planning, the following information where known, should be provided to the crane operating subcontractor prior to commencement of work on site.
    1. location and details of underground cavities,
    2. location and details of underground services – electrical, water, gas etc
    3. location and details of excavations – disturbed and uncompacted ground,
    4. locations of embankments and soft surfaces,
    5. potential overhead structures (electrical lines, bridges, etc),
    6. necessary load/working requirements (mass/nature of loads, frequency, positioning),
    7. foreseeable operating limitations.

This may be part of pre-work consultation or a defined scope/tender given by Silverback

Crane Operator OH&S Documentation

  1. The documentation that a subcontractor/crane operator is to maintain, and make readily available for review by a Silverback supervisor, is to include the following items.
General
Mobile Crane Plant Registration
List of workers undertaking prescribed work involving the mobile crane (Rigger, Dogger, Crane Operator)
Pre-Operational and Erection Safe Work Methods/Procedures/Checks
Full details of the erection procedure (if applicable)
All components of the crane are to be inspected by a competent person on the ground prior to erection
All crane attachments/lifting gear is to be tested and tagged and in a serviceable condition for use on site
Operational Safe Work Methods/Procedures/Checks
Full details of the procedures for operation of the mobile crane are to be maintained. This is to include:

  • Isolation and demarcation of site areas where required,
  • Load Rating Charts and calculations – identifying the various crane configurations/operating radii and the designated safe working limits for each configuration (these are to be displayed permanently in the crane cabin or operating position,
  • Wind considerations,
  • Travelling with loads considerations,
  • Operation in the vicinity of overhead hazards and powerlines.
Full details of all inspections, repairs and maintenance are to be maintained in a logbook.
Regular inspections are to be undertaken to ensure safe work practices are being correctly undertaken. These include:

  • Pre-operational daily inspections
Dismantling Safe Work Methods/Procedures/Checks
Full details of the procedure for dismantling of the mobile crane (if applicable) is to be supplied with subcontractor/crane operator documentation, separate to those provided for erection of the crane.
Maintenance Safe Work Methods/Procedures/Checks
Competent and authorised personnel only, shall carry out all repairs and maintenance activities.
Where any part of a crane or ancillary equipment becomes worn or unserviceable or may constitute a hazard before the next inspection then this item shall be replaced/repaired in accordance with the manufacturer’s recommendations.
  1. In the event that information maintained by subcontractors/crane operators does not contain adequate information then Silverback must not allow the mobile crane activities to commence and/or continue until all required documentation is available.
  2. The mobile crane is to be operated in accordance with the manufacturer’s recommendations and requirements.
  3. Any Silverback personnel on site or subcontractor who identifies a hazard related to crane operation on site must immediately report the hazard to the Construction Supervisor and the crane subcontractor/operator.
