Welded structure made of stainless steel tubes Ø 21/33,7 mm, glass bead blasted, screw-fitted flange fixing to posts

Tower hood
High pressure laminate 15 mm

Top element
Three-piece wind rotor

Access to platform at 1,00 m
climbing net access from Hercules ropes, Ø 16 mm, mesh size 300 m x 300 mm (axial dimension)

Combined roller/tunnel slide
Installation height: 6,00 m

Roller slide diameter: 0,96 m
Tunnel slide inclination: 30°/38°
Tunnel slide diameter: 0,80 m
Sliding sheet metal thickness: 2,5 mm
Stainless steel roller slide sections
Grip openings on both sides of the entrance section, roller slide sections with interior handrail guideway made from stainless steel, one-piece welded assembly.
Stainless steel rollers mounted to anti-friction bearings.
roller diameter: 50 mm
Centre pylon: hot-dip galvanised tubular steel Ø 298,5 x 7,1 mm/stainless steel metal sheet covering Ø 313 x 2,5 mm
Sliding sections from stainless steel, of low noise level thanks to trough shape, slide in five parts, including appropriate connecting flanges to facilitate installation on site.

For your planning, due to a possible sliding surface heating, please see to a north-east orientation of the slides or provide half-shade of trees.

Plank bridges, length 6,83 m / 7,35 m
V-shaped climbing net construction from Hercules ropes, Robinia footbridge with approx. 40 mm clear distance between the planks. Attachment to a steel frame construction, barrier height approx. 0,75 m, with Robinia support posts Ø 120 mm

Playing structure
– posts made from stainless steel tubes Ø 120 mm covered by non-detachable protective stainless steel caps.
– platforms from boards of 30 mm thickness and all-round square-shaped joists 45 x 100 mm. Dried timber from Robinia, planed, milled and free from decay. Force-fitting fastening through specific stainless steel brackets with end-to-end bolt assembly.
– bowed guardrails with roll-off prevention, from stainless steel tubes, Ø 33,7 x 2 mm
– timber infill barriers from Robinia, 125 x 30 mm, fastening between stainless steel tubes Ø 33,7 x 2 mm
– tower roof, inclination 72°, made from highly weather-resistant HPL, 13 mm thickness with revolving tower flag

Anchorage
Dowelling of each base plate by means of 2 stainless steel injection anchors, material specification A4.
As damage protection, the tower is equipped with a lightning conductor.

The foundation sizes indicated in this quotation correspond to static requirements for soils with moderate solubility with an admissible footing pressure of at least ?R,d = 150 kN/m².
With a deviating soil characteristic or with installation in areas with a high wind load (differing from wind zone 2 in Germany, equates to vref = 25,0 m/s) or with a high snow load (differing from snow load zone 2 in Germany, equates to sk ?0,85 kN/m²), technical modifications of the product construction might become necessary (for instance the addition of cross bracings). Thereby, additional costs and the extension of the delivery time will arise.
Upon request of the customer, Kaiser & Kühne can engage a recognised engineering office to establish the necessary static calculation. The customer must bear the costs arising hereby. Any necessary evidence of the local conditions must be provided by the customer.
