4.2.2. Minimum load
When the load is only little, the motion of the stages of the booms may not be smooth, due to
x
friction in the hydraulic cylinders
x
friction in the booms
To ensure smooth motion, the units have to be loaded with at least 50 kN. In most cases the
mass of the header beams is sufficient.
Enter the minimum load in the checklist given in Appendix A
“ Checklist for planning a lifting
operation ”. Do such for the unit which is bearing the lightest load only.
4.3. Side shift units and lifting lugs
4.3.1. Side shift units
When you want to move the load in transverse direction then you have to apply side shift units.
x
Check the capacity of the side shift units, using the information in section 3.2.2
“ Operational specifications ”.
x
Enter the load in the checklist given in Appendix A “ Checklist for planning a lifting
operation ”.
4.3.2. Lifting lugs
If there is no need to move the load in transverse direction then simple lifting lugs can be
applied, rather than the more complicated side shift units.
x
Choose single- or double plated lifting lugs, depending on the mass of the load
x
Check the capacity of the lifting lugs, using the information in section 3.2.2 “ Operational
specifications ”.
x
Populate the checklist given in Appendix A “ Checklist for planning a lifting operation ”
with the mass of the load to be lifted.

Always determine the force on the side shift units, even for relatively light
loads. In case of any doubt, consult Enerpac.
Attention:
The force on the side shift units shall never exceed their bearing capacity.
