Loading System MkII Technical Data

Ballast
The Loading System MkII Base needs to be loaded with a minimum 1500 kg
of suitable ballast to keep it stable and meet the requirements in the standard.
The ballast can be applied in three different ways, which are presented below.
Further details on how to perform the ballast loading procedures are
described in the Assembly chapter.
• Precast Kentledge
The Precast Kentledge is a 800 kg concrete block designed to fit into
the Loading System MkII Base. Using two units of the Precast
Kentledge is enough to achieve the weight requirement and provide
margin in case of wear of the blocks. These should be ordered as an
option as they are not included as a standard. It is recommended to
use these blocks due to i ts precise weight and safe positioning.
• Concrete box cast on site or gravel box
For this option, the Formwork Supports should be ordered, as they
are not included in Loading System MkII as standard. With the
Formwork Supports mounted, a plywood box inside the Loading
System MkII Base will make it possible to cast concrete into the box
directly on site. It is also possible to fill the plywood box with gravel.
• Other ballast option
In case none of the standard solutions noted above is used, it is
possible to use other ballast types. In this case it is the customer’s
responsibility to ensure that ballast:
• Has a weight no less than 1500kg
• Is distributed centrally on the Bottom Frame of Loading
System MkII
• Has no possibility of movement.
