4.2.4 Requirements for foundation material
Permitted filler material for the foundation material is hard wood with a mechanical compressive
strength of at least 25 N/mm² without any occurrence of deflection.
However, Enerpac strongly recommends adhering to 30N/mm²; preferably Azobé.
The minimum hard wood thickness is 50 mm and the maximum thickness is 150 mm.
Wood is a product of nature, which means its quality is not standardly assured. In order to
guarantee quality an appropriate test has to be conducted before use to verify that the material
meets the set requirements.
NB
• Wood is a natural product: its quality is not assured. In order to
guarantee quality, test the timber on 125% of the expected load.
• For your planning keep in mind that suitable wood may not always be
available immediately.
Hazard
Use of other wood types such as plywood, multiply, pine and compressed
wood is explicitly prohibited.
In case of doubt, consult Enerpac.
Hazard
Minor deformations in filler material or subsoil may result in strong internal
transverse forces or diagonal or longitudinal movements of the load or masts.
Use of other wood types such as plywood, multiply, pine and compressed
wood is expressly prohibited will endanger the stability of the system.
Therefore, use of other types is strictly forbidden.
NB
• For your planning, please bear in mind that the ideal wood is not only
hard to the touch; it is also hard to acquire.
• It is the responsibility of the customer that the foundation of the system
is sufficient and according to the specifications.
