type E1

This 3-piece folding ladder is especially suitable for shaft pits which do not allow the fixing of a pitladder to the shaft wall or if floor fxing is required due to design reasons (e.g. panoramic lifts).

Thanks to its two pairs of hinges, type E1 is the ideal access ladder in shafts with low shaft depths and high pit depths.

The pit ladder is equipped with an adjustable hook profile which has to be placed in the sill groove to avoid tilt back during use. If the ladder can be installed only parallel to the shaft door opening, an optional electrical switch should be used. The switch can be installed on the floor or at the shaft wall alternatively.

The ladder is pulled up from the pit with a chain and locks in automatically. After use, the type E1 is unlocked with a separate release rope before it can be folded back into the pit.

The floor-mounted jack ensures a safe ladder position at any time. It also functions as a guiding system when the ladder is brought from a folded position into an unfolded position. For hydraulic lifts the jack can be fixed to the shaft wall with an additional holder in order to avoid drill holes on the shaft floor which are generally not allowed.

The ladder comes with fixing material. Besides the electrical switch and the jack holder for hydraulic lifts it can also be equipped optionally with a handrail extension.

The pit ladder type E1 complies to DIN EN 131 + DIN EN 81-20/50.
