PURPOSE:
Replacement of elevator installations with steel ropes of the previous generation, especially those that have worked out the standard service life.
DESCRIPTION:
Development of a new design of lifting elevator installations based on an improved drive system and the use of a traction member made of steel cables, wrapped in a rubber sheath. New flat rubber-cord ropes, reinforced with small-diameter cables, having small bending radii and protected from corrosion are proposed. A compact gearless winch for rubber cord ropes with a small bending radius and a traction sheave d = 125-150 mm has been developed.
ADVANTAGES:
4-5 times increased durability of the traction element and its reliability – reduced energy consumption of the elevator installation:
-
- reduction of the installation dimensions (do not require a machine floor);
- use of a gearless winch;
- a significant reduction in noise levels and an increase in the smoothness of the lift;
- traction cables are fully protected by a rubber sheath and do not corrode;
- monitoring the integrity of the ropes (24 hours a day).
TECHNICAL AND ECONOMIC EFFECT:
The expected economic effect from the renovation of the elevator facilities and the replacement of ropes on the used elevator installations will give an annual savings of more than UAH 35-40 million. With the further replacement of the rubber cord rope of the entire fleet of elevator installations in Ukraine, the annual savings will amount to more than UAH 165-200 million. The volume of necessary capital investments for the re-equipment of one elevator installation is UAH 180-190 thousand. The term for the design work is 6 months. The payback period is 5-7 years. The volume of necessary investments for the organization of production – UAH 250 thousand.
RECOMMENDED FIELD OF APPLICATION:
Housing and communal services, institutions where elevator installations are used.
RESULTS OF THE RESEARCH:
Provides consistent results.
STAGE OF THE DEVELOPMENT READINESS:
Introduced into production.
TRANSFER OPPORTUNITY:
-
- Realization of finished products.
- Joint production, sale, operation.
- Sale of patents.
NOVELTY:
7 patents of Ukraine.
