The ladders are made entirely from insulating section fiberglass plastic according to non-metallic technology and satisfy all demands of actual normative and technical documentation.
In dependence on designation lower ends of stringers are provided with the rubber thrust bearings or metallic tips. Upper ends of the ladder are provided with the heads.
Special sag protects upper step and stringers from destruction while working on the pillars, corners of buildings, etc.
There are struts on the upper and lower parts of the ladders for increasing rigidity of the construction.
The working surfaces of the steps have the coating averting sliding of the worker’s shoe’s soles.
The ladders can be equipped with special grapples for hinging on the cross-arm or construction.
There are two types of ladders: with parallel and diverging stringers. The ladders with parallel stringers are used in wells and have letter “T” in its marking.
The standard distance between steps is 330 mm, and for ladders with parallel stringers – 250 mm.
