They extend the life of the bell and improve the sound. With every touch of the wall of the bell, the heart brings out its sound. The harmonic sound is soft, as Rduch Bells & Clocks has developed a new form of the heart. Due to the optimum mass and dimensions, four essential parts of the heart are perfectly coordinated. The bell sounds beautiful and resonates. In addition to the blade, stem, sphere, tail of the heart, and the bell itself, the suspension and the entire fixing of the heart must cooperate properly.
The drive that should guarantee gentle rattling, optimum power, proper tilting angles and soft braking - these are the factors that are stressed by us the most. The lower the tilting angle of the bell is, the lower the dynamic loading of materials and structure is. By using the Rduch Clapper heart by as, the tilting angle was reduced as much as 10° with respect to traditional hearts, but with proper dynamics. By using the heart forging technology in our company, we achieve the best possible properties.
The heart is ideal, light and soft enough to protect the bell from deformation and cracking. Even after decades, with the increase in hardness, the bell still sounds beautiful like singing. Hard, heavy heart causes the bell to sound heavy and metallic. Our forged heart is a genuine Polish export product. due to the innovative solutions supported by knowledge and traditional technology, we give the work of folk art the impetus for a new life.

The suspension of the bell is a part of its additional equipment and is sometimes referred to as a “yoke” or “bell axis”. For centuries, it was made of wood (e.g. Zygmunt's bell), only the brackets and pins were steel. In the first half of the 20th century, mainly with the development of electrification, a mass installation of steel or cast iron suspensions began. The reason was the desire to modernize and improve and facilitate the operation of electric engines. This is evidenced by the absence of these mounting brackets on the rope for manual operation. Unfortunately, a number of companies still believes this is the only and best possible solution.
However, each solution has positive and negative implications, and only knowledge and experience allow to select the right one.
This is a standard type of the suspension used in Western European countries, compliant with DIN 4178. Due to this method, we achieve the best ringing dynamics, hearing range and maximum possible life of the bells. Tower forces are, however, the largest of all suspension methods. Forces can be greatly reduced using the innovative CLAPPER-RDUCH® heart.
A common solution e.g. in Italy to reduce the forces acting on the tower to achieve a similar ringing dynamics as in a straight suspension.

Proper bracing of the bell has greatly influences on the smoothness of the bell movement, and should, by its fluctuations, eliminate minor bumps in the foundation. Loose and resistance in the bearings can adversely influence on the bell construction and, consequently, the entire bell tower.
The RDUCH-BELLS & CLOCKS designs are perfect for a tower of a church, as well as for the suspension of the bells. The main focus is on the cushioning of the structure to eliminate the destructive influence on vibration caused by ringing. The special innovative system, i.e. WIBRO RDUCH, prevents from it.
In classic buildings, we offer classical oak structures in accordance with DIN 4178. It is a centuries-old and classic method to found the bells.
In modern temples or for other justified reasons, we design and produce steel structures, each with the new system, i.e. WIBRO RDUCH.
Due to many years of experience and cooperation with a number of design offices, a bell-shaped model was founded directly on a reinforced floor plate on which the stand-alone WIBRO RDUCH system is located. This is a very comfortable solution, technically optimal, and most importantly, it does not shake a church.
An interesting solution for RDUCH BELLS & CLOCKS is the combination of a classic, straight, oak-type steel structure.
RDUCH BELLS & CLOCKS author's solution is the best method to install the bells on open church towers in terms of aesthetics. The suspended WIBRO RDUCH system eliminates vibration transmission to a church tower
