Hardwood packing should be used between
the load bearing blocks and the chassis to to
cushion the weight and reduce the
transmission of vibration.
Concrete blocks should not be in direct
contact with the steel chassis.
JACKING
Selection of Jack
It is essential to ensure an appropriate jack is
selected for any lifting operation. All jacks
must have their maximum lifting capacity
(safe working load) clearly and legibly marked
with a permanent label or painted sign. Care
must be taken to ensure the marked lifting
capacity of the jack(s) is not exceeded. The
jack(s) selected should be capable of lifting
more than half the weight of the caravan; the
distribution of the load and the nature of the
terrain should be taken into account.
Jacking Procedure
• Most jacking accidents occur when lifting
on an uneven surface when the jack slips
out from under the caravan holiday home.
Therefore care is necessary to ensure the
jack is sitting on an even surface that is
capable of taking the full-imposed weight
at that jacking point, as indicated by the
caravan manufacturer. Spreader plates
should be used on uneven and/or soft
surfaces;
• Before raising the caravan holiday
home, the wheel(s) remaining on the
ground should be chocked;
• Wherever possible, consideration should
be given to lifting the caravan holiday
home whilst still hitched to the towing
vehicle to take advantage of the
additional stability this can provide;
• The jack(s) should be placed under the
defined jacking point(s)
• Jacking should be undertaken, one side
at a time, using an appropriately rated
jack(s);
• The caravan holiday home should not be
jacked up to its final height and then
supported. Rather, the caravan holiday
home should be lifted up to a height
whereby the support stand is barely
extended to allow the earliest possible
supporting of the caravan holiday home.
The jacking should be slow and gradual
and the caravan holiday home should be
continually supported throughout the
jacking operation;
• It may be necessary to lower the caravan
holiday home onto the support stands
and to reposition the jack at another
designated jacking point to gain more
height;
• While jacking at other points, it is
important to check and recheck all
support stands to make sure they remain
in the correct position.
