4 Plan an operation
In this chapter, all planning activities for a lifting operation are described.
NB: It is of the utmost importance to read this whole chapter carefully before
start the lifting operation.
4.1 Properties of the operation
1. Populate the checklist given in Appendix A “Checklist for planning” while you’re planning
2. Make sure the following information is available:
• Mass of the load.
• Centre of gravity of the load.
• Dimensions of the load.
3. Determine the position of the load’s centre of gravity within the units
4. Determine the maximum lifting height
5. Consider the following subjects:
• Bearing capacity of the subsoil.
• The wind load
NB
• It is of the utmost importance to read this whole chapter carefully before
start the lifting operation.
• It is the responsibility of the customer that the foundation of the system
is according the specifications.
Hazard
failure to prepare correctly for a lifting operation may result in loss of system
stability during use.
4.2 Ground bearing pressure and foundation
This chapter describes
• how to calculate the ground bearing pressure
The ground bearing pressure is calculated in relation to
• the mass of the load
• the maximum swivel height
• the side load
