3.7 Anchors
It is good practice to anchor the RPH to the
ground. Some insurance companies require
they are anchored and specify minimum
requirements.
The anchor points on the chassis are rated at
10kN in tension therefore the ground anchors
should also be capable of withstanding the
same.
The chassis’ used for Swift RPHs have specific
holding down points located approximately
1000mm (+/-200mm) from the ends of the main
longitudinal chassis member at each corner
(see Fig. 2).
CAUTION: These anchors should not be
over-tightened as they can stress the chassis.
i
Note: It is important to note that both the
chain and turnbuckles should be suitably
rated.
Swift recommends that the person responsible
for the ground installation provides anchorage
points to prevent the RPH from overturning
if local climatic conditions result in wind
velocities in excess of 48m/s (173km/h) being
experienced.
i Note: Each ground anchor should be
capable of resisting 10kN in tension.
The preferred turnbuckle is the type which has
an ‘eyelet’ at both ends (as opposed to hooks)
and should be used with suitable ‘D’ shackles.

3.8 Snow loading
All Swift RPHs are designed to withstand a snow
loading of 1500pa (pascals) which equates to
Grade B (see below).
To withstand this snow loading the following
method of supporting the RPH when sited must
be carried out.
The main longitudinal chassis beams should
be supported by concrete blocks where cross
braced on either side of the axle. An axle stand
should be placed underneath the cross bracing
between the concrete blocks and the corner
steadies in four positions as shown in Figure 3
(page 18).
Great caution should be used when cleaning
snow from the roof of the RPH.
