Fiberglass ladders are distinguished by their modern design, as well as ease of operation. Working with electrical appliances and electricity in general is dangerous to people's lives and their health. To prevent adverse situations, it is necessary to use special means aimed at protecting against the effects of electric current. The dielectric stepladder is considered a modern tool for such work.
Features fiberglass fiberglass stepladder
A ladder-ladder is required for workers who conduct their work on a hill. Aluminum and steel structures are dangerous for electrical work, as well as for repairing electrical wiring and replacing bulbs.
It should be noted that even special tools designed to protect (for example, work clothes and tools with insulated handles) are often not enough. Fiberglass ladders help reduce and eliminate possible electric shock.
Fiberglass or fiberglass is based on a fibrous filler. It consists of threads, flagella, as well as fabric. All thermoplastic polymers bind this. These include various types of resins, such as polyester, vinyl ester and epoxy types. This is an expensive material for production, respectively, prices for fiberglass ladders are higher than for metal structures. Such stairs are in 3 steps, however, models in 5 or 7 steps are popular.
Thermal conductivity of plastic is low, therefore, according to its characteristics, it is closer to wood. Plastic does not allow hands to freeze, does not heat up in the heat. Thermal conductivity may be the same for wood and fiberglass, but according to other criteria, the fiberglass is definitely better. A number of advantages: stronger, mold does not start in the material, insects do not appear. The material does not rot.
Fiberglass is heavier than aluminum structures, but lighter than steel. It is quite easy to transport stairs from fiberglass. Professional stepladders reach a height of 3 meters, their weight is 10 kilograms.
In terms of strength, the fiberglass component is slightly inferior to steel. Of course, the absolute strength of steel exceeds fiberglass. However, fiberglass has a small weight and specific strength. Its characteristics have more advantages than steel.
Another plus of plastic is that it cannot corrode. A fiberglass staircase can last more than 20 years. She calmly withstands rainy weather, heat and severe frosts.
Insulating Dielectric Model
Fiberglass differs from others in its dielectric properties. Stairs made of aluminum and steel cannot guarantee such electrical safety.
Fiberglass designs are tested with a voltage of about ten kilovolts. One of the important qualities of fiberglass is intrinsic safety. The stepladder does not light up from sparks that fly out of the grinder when welding is carried out.
Rubber thrust bearings guarantee safe operation on dielectric ladders. High-quality fasteners also affect the choice of design, they give reliability to similar stairs.
Many of these stairs have latches that prevent involuntary opening.
Such stairs are designed for the following types of work:
- troubleshooting at home;
- connection and maintenance of various electrical appliances;
- carrying out work at height;
- work under power cables;
- for work in rooms with electrical wiring on the floor without voltage.
Step ladder selection
When choosing this design, we first determine the height of the desired product. This is due to what actions will be performed in the future. There is a lineup in which it is not recommended to get up to the upper stage, since you can easily lose balance. Steps of a step-ladder are better for choosing wide, intended for comfortable work on them.
Works associated with a height of more than four meters are used by stepladders with scaffolds. They have wide upper areas and special fences. This makes it possible to safely perform work at heights.
Corrugation on the steps is considered mandatory. Deep corrugation has a sharp edge design, thereby providing the shoe with a comfortable grip. For corrugation, abrasive chips and an aluminum profile are used.
Wheels for transporting the structure make it possible to move the ladder faster and more convenient. Some models even have tips for working on soft ground.
Preference should be given to ladders with a tray designed specifically for storing various kinds of electrician tools.
The main key features of quality step-ladders include:
- structural stability with symmetrical support;
- high-quality and operational assembly;
- convenient operation and safe use and storage;
- mobility in use.
For the manufacture of stairs using the following materials: steel, aluminum, plastic, wood.
Step-ladders can be one-sided, two-sided or even three-sided, however, they are more common in production.
When buying, you must pay attention to the following details.
- The height of the platform is the length between the support and the upper step. Each model has its own distance. It is important to clearly understand for what needs you are using this subject: for home or in industry.
- Steps, their number: the smaller the distance, and also the more steps, the more comfortable the use of a stepladder.
- The workload shows what maximum weight the upper stage can support without the risks of stability of the staircase itself.
- The presence of additional useful tools for comfortable and mobile work, for example, the presence of wheels, a block for various tools, as well as a hook for a bucket.
