Torrifaro a piattaforma fissa con piastra di base

Fixed Platform High Mast with Base Plate

Ideal for sports facilities of any size and large areas, these structures offer a versatile and cost-effective solution.

They have a truncated conical shape with a polygonal section and are made of S355JR steel sheet (UNI EN 10025 standard) through press-bending and subsequent longitudinal welding. They consist of multiple sections, joined using the slip-on-joint method.

The fixed platform high masts with base plates are anchored to the foundation block using anchor bolts embedded in the concrete, provided they are equipped with a base plate welded to the lower section of the mast. The welds are carried out using procedures approved by the Italian Welding Institute, performed by qualified personnel, and tested in accordance with UNI EN 3834-2 standard.

Each high mast is equipped with an access ladder, which can be of three types:

  • Modular curved ladder with full-length guardrail
  • Modular curved ladder with full-length guardrail equipped with a central “T” guide, to be used with a CE-marked fall protection safety device
  • Modular rung-type ladder, Safety type, equipped with a central “T” guide, to be used with a CE-marked fall protection safety device

The modular ladder is positioned behind the lighting face and attached to the mast using welded supports. At the top of the mast, there is a platform whose dimensions vary depending on the number of installed floodlights. The platform, accessible through a hatch in the walking surface, allows maintenance of the floodlights in safe conditions.

The mast is also equipped with a number of resting platforms that vary according to the height of the pole, fixed to the mast using welded supports. In towers using Safety ladders, resting platforms are provided.

The structures are CE-marked and manufactured in compliance with UNI EN 1090 standard with an execution class of EXC 2. The high masts are hot-dip galvanized by immersion in a zinc bath in compliance with UNI EN ISO 1461 standard. Upon customer request, powder coating is available, performed according to the UNI EN ISO 12944 standard.

  • Procurement of materials (profiles, sheets…)
  • Prefabrication in the workshop
  • Storage in the workshop
  • Surface protection treatments (hot-dip galvanization)
  • Material inspection documents
  • CE marking of structural components

  • Mechanical installation of floodlights and accessories as specified in the final design
  • Issuance of completion certificate

1.3 Description of the supply

The supply includes the following works:

Fixed high mast with a top platform, designed for the installation of n° __ floodlights, model ________, on a single face, composed of the following elements.

MAST

Of truncated conical shape with a polygonal section, it is made of press-bent and longitudinally welded S355 JR steel sheet. The welding is carried out in accordance with UNI EN ISO 3834 standard using a process approved by the Italian Welding Institute.

It consists of three sections to be joined on-site by overlapping them using the slip-on-joint method.

The base section is prepared for anchoring with a base plate on foundation bolts pre-cast into the foundation block and is equipped with a grounding plate.

LADDER WITH GUARDRAIL

The rung ladder, made of modular steel elements and equipped with a protective cage, is positioned on the axis of the mast behind the lighting face and is attached to it using bolted elements.

REST PLATFORM (n. 1)

Measuring 1000 x 620 mm, it is positioned along the same axis as the access ladder, equipped with an anti-slip grating floor, complete with a toe board and a closable access hatch, and a protective railing 1200 mm in height with an intermediate bracing.

FINISH

The entire structure, including all steel components, is hot-dip galvanized by immersion in a molten zinc bath, in accordance with UNI EN ISO 1461 standards.
