How to choose the right width of a well ladder?
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 manhole. Investors with non-standard requirements can choose custom-made ladders. Our assortment includes well ladders with a universal width of 0.34 m.
What material should a well ladder be made of?
Manholes require 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.
You can also find cheaper products made of ordinary steel on the market. The material of the ladder must be adapted to the conditions prevailing at the installation site. Thanks to this, the equipment will remain in good technical condition for many years. For example, shaft ladders made of stainless steel are resistant to sewage disinfected with chlorine - unlike structures made of ordinary steel. In turn, plastic models are intended for wells with electrical installations, which prevent dangerous sparking. However, 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 fixings to the ground.
