Helicoidal stairs for tanks

TLC tank staircases are specially designed to provide safe and reliable access to industrial tanks of various sizes. They are essential in facilitating maintenance, inspection, and service work for tanks used in different industries such as petrochemicals, food processing, water treatment, and energy. Built with durability and safety in mind, these stairs meet the highest industrial standards and can be customized to the specific requirements of each installation.

Usage

 TLC’s helicoidal staircases are suitable for various types of tanks, including:

  • Bioenergy tanks: Providing safe and efficient access to bioenergy storage and processing tanks for routine inspections and maintenance of equipment.
  • Storage tanks: For large storage tanks, the spiral design allows operators to easily access different levels of the tank while minimizing the footprint of the staircase.
  • Chemical and petrochemical tanks: Ensuring compliance with strict safety standards, our staircases provide access to tanks storing hazardous chemicals or petrochemicals.

Advantages of helicoidal Stairs

  • Space-efficient design
    One of the most significant advantages of helicoidal staircases is their space-saving design. The spiral configuration allows them to wrap around the exterior of the tank, requiring far less ground space compared to traditional straight staircases. This is particularly beneficial for facilities where every square meter of space counts.
  • Enhanced accessibility
    Helicoidal stairs provide continuous, easy access to various levels of the tank. Whether for routine inspections or emergency access, these stairs allow personnel to reach control and measuring instruments without the need for ladders or scaffolding. This is crucial for tanks where frequent access to upper levels is required.
  • Low maintenance
    Helicoidal staircases from TLC are built to last with minimal maintenance required. The materials used are resistant to corrosion, wear, and environmental stressors, ensuring that the staircases retain their structural integrity and safety features over time. This reduces the need for frequent repairs or replacements, saving both time and operational costs for your facility.

FAQ

Helicoidal stairs for tanks provide safe access to different levels of the tank during inspection, maintenance and servicing work. They also allow convenient access to control and measuring instruments without the need for ladders or scaffolding. Depending on whether the tank is welded or bolted, we design brackets that transfer the weight of the structure together with the required loads.

Their main feature is a space-efficient geometry that allows the staircase flight to run around the external part of the tank. As a result, helicoidal stairs take up less space than traditional staircases.

Yes. Helicoidal stairs can be adapted to the specific requirements of the installation, the type of tank and the technical conditions of the facility. The design takes into account the function of the stairs, the geometry of the structure, live loads, environmental conditions and project requirements.

Yes. The stairs are designed in accordance with international safety standards, including EN ISO 14122. They can be equipped with handrails and anti-slip steps to ensure safe use in industrial conditions.

Helicoidal stairs are made of structural steel protected by hot-dip galvanizing in accordance with EN ISO 1461, which ensures resistance to corrosion, wear and environmental factors. The corrosion protection system can be selected according to the corrosivity class of the environment in accordance with EN ISO 12944, and for demanding conditions additional coating systems can be applied.

When ordering helicoidal stairs, the type and geometry of the tank, the required access range, the operating conditions and the method of supporting the structure should be taken into account. Safety requirements, corrosion protection and installation conditions are also important. If the tank has not been designed to carry the staircase load, the TLC design team prepares a support structure from ground level for the entire system. Such situations occur, for example, during tank refurbishment projects when the client replaces a ladder with stairs in order to increase safety and improve the comfort of service work.

No. Helicoidal stairs can be designed for tanks of various diameters, and the solution is adapted each time to the parameters of the facility and the requirements of the project requirements.
