 The piling and drilling rigs are exposed

to significant hazards when they are used as intended, and they are associated with the following:

 TRANSPORT  EQUIPMENT IN SERVICE  MAINTENANCE  MOVING ON SITE  STORAGE  DISABLING AND SCRAPPING

STABILITY OF THE RIG Example/comments:

Firstly, as you saw ,whenever we have motion of the parts or components on the machines the COG does not remain in the same position.

The State of the Stability of the machine is not permanent and is changing all the time during the operation.

All calculations done by designer are related to the temporary and particular state and position of the machine as a whole assembly and motions of its components.

Position of COG of the DFE can be used for considering the STABILITY of the DFE

  • nly as temporary and it is changing position all the time.

Because the COG does not remain in the same position, the STABILITY ANGLE is not STATIC and will change its value at all times during the DFE operation.

Consequently, the ground pressure imposed on the ground by DFE is not constant and is changing its magnitude all times during the process of drilling or piling.

 (c) Track type crane, on crawlers

The tipping condition of a track-type crane supporting a load on crawlers is deemed to have been reached when two-thirds of the track that is normally in contact with the supporting surface remains in contact with the supporting surface and the application of an additional load moment causes more than one-third of the track to lose contact with the supporting surface

DRILLING & FOUNDATION EQUIPMENT SAFETY –as prEN16228-1/……./7 On 19 September 2008 a serious incident occurred near Tully in North Queensland when a 30 metre tower of a pile driving rig became detached from a lattice boom crawler crane and fell with a 12 metre long concrete pile. One worker, located

  • n the ground in front of the crane, was fatally injured. The

crane operator was critically injured when one end of the pile became embedded in the crane cabin as a result of the fall.
