Stepladders with
symmetrical DSS and vertical DSV support (wall-mounted) are
designed for work at power, telecommunications, metro and other
enterprises. Rubber thrust bearings are installed on the lower ends
of the bowstrings. To prevent spontaneous spreading during
operation and keeping in a folded state, the ladders have a
hook-type device. For convenience and safety when performing work,
the working platform of the step ladder is equipped with a handrail
- a support for the hands. The steps are sprayed to prevent
slippage of the worker\'s shoes. Step step *4 cm, height from 1.5
to 3.7 m, height of the working platform from 0.8 to 3m, weight
from 8 to *6 kg.
