4. Structure
4.1 Planning information
•
The type of pit arrangement and the area surrounding the pit depend on the local
conditions.
•
Ask the landscape gardener or responsible building company which digs out the pit
in case of any doubt.
4.2 Assembly instructions
The trampoline is delivered disassembled. Sufficient numbers of helpers are required
to unload the trampoline from the truck and bring it to the place of installation. The
trampoline can be installed ready-for-use on-site by the retailer‘s trained personnel in
individual cases on request.
4.3 Weight
The weight per frame is approx. 150 kg without impact protection.
4.4 Digging the pit
•
Dig out the pit according to the installation draft (see page 5).
•
Pit edge reinforcement should be planned if the ground is not stable (sand).
•
A fully circumferential foundation can be placed in the pit, on which the frame parts
are positioned, or the corresponding pedestals should be at least planned in the
corners.
•
The pit edges in the lower area should be excavated at a slight angle to prevent the
soil from slipping down.
•
The pit base should have a drainage possibility (e.g. layer of pebbles) if the base lay-
er is not permeable to water, so that the water can soak into the ground. There is
otherwise the danger of the pit filling up with water if the ground is not permeable
to water (clay or cement layer).
4.5
Surrounding area design
The design of the area surrounding the ground trampoline depends on the specific
conditions in individual cases. An impact protection with a natural base or another
suitable type of impact protection (designed for a free fall height of 100 cm) should be
foreseen.
