ASSEMBLY AND ANCHORING
6-3 MSHF • 7295-026A
6.2 Ground support
Before the position for the mast
climbing work platform is prepared a
check must be made to ensure that
the distance between the mast and
the working surface can be spanned
by the standard anchoring material.
1. Ensure that the forces are spread
over as large an area as possible.
2. The soil must be able to withstand a
ground pressure of at least
2 kg/cm² / 30 lb/in². If this requirement
is not met, soil improvement must be
carried out such that the ground
satisfies this minimum requirement.
3. The ground support must be flat and
centrally loaded with a minimum
ground support of 400x400 mm /
15.7 x 15.7 in.
When a chassis is used, a ground support
must be placed under the jack close to the
mast and under the jack of the 4 extending
legs. The frame must have a support
placed under the mast and under the 4
corners (not under the jacks).
4. The ground support must be durable
and of such a quality that the load can
be transferred without plastic
deformation.
5. If the machine is installed on a
concrete foundation or on a hard
road surface, the installation must be
provided with wooden packing to
prevent slipping.
