How to choose the right width of a ladder for a well?
The well ladder is available in various widths and lengths, with a different number of rungs. The width of the ladder should be adjusted to the free space in the well. Investors with non-standard requirements can decide on ladders made to measure. In our assortment you will find well ladders with a universal width of 0.34 m.
What material should a well ladder be made of?
Manholes require the use of durable and solid solutions, resistant to mechanical damage and weather conditions. High-quality shaft ladders are most often made of:
- aluminum,
- stainless steel,
- hot-dip galvanized steel,
- modern plastics.
Cheaper products made of ordinary steel can also be found on the market. The material used to make the ladder must be adapted to the conditions at the installation site. This will ensure that the equipment remains in good technical condition for many years. For example, stainless steel shaft ladders are resistant to sewage disinfected with chlorine - unlike ordinary steel structures. In turn, plastic models are designed for wells with electrical installations, which prevent dangerous sparking. On the other hand, damp or wet tanks require the installation of a stainless steel ladder.
It is worth knowing that ladders used in manholes and shafts must meet the requirements of a special European standard (DIN EN 14396). The requirements apply to installation using wall brackets and ground fastenings.
