Modern step-ladders
Ladder and step-ladder are two greater differences. Ladders may be of various kinds and they differ from step-ladders by the fact that they refer to “added”. Ladders are being put to wall - otherwise it will be impossible to get on it. Step-ladders stand independently. And, as experts say that, step-ladders may with bilateral and unilateral climbing.
Bilateral climbing occurs when steps are located from both parties of the step-ladder.
Except for steps, the step-ladder is still equipped with racks. The step-ladder has also legs (on which the step-ladder stands) and hand-rail (it is not obligatory).
The height of a step-ladder is defined by last step or platform. The distance between steps is, as a rule, about 22-25 centimeters. Usually step-ladders have five or six steps - having raised on its top platform it is possible not only to hang up curtains, but also to touch ceiling. Of course, some step-ladders are quite higher - sometimes they have even seven or even eight steps.
The universal step-ladder can be both a step-ladder, and a ladder, depending on owner????????s desire. It consists of two-three sections and each section consists of 6-8 steps. Putting forward section one after another -as a telescope (not without reason such step-ladders name still telescopic)- it is possible to construct quite high ladder. Junctions of sections are fixed by special hooks or automatic clamps. However, universal step-ladders may be not only telescopic, but also simply folding: when sections are not put forward one after another.
