Rubber Buffers / Cellular Buffers Program 0170 / 0180 General Information Stop buffers are essentially damping units that absorb energy, for example at the end of a crane runway, to prevent damage and allow for smaller structural dimensions. In general, “energy before geometry” applies to buffers because load diagrams, precisely defined characteristic curves, physical dimensions, and mathematical formulae are used when dimensioning the buffers. Geometrical dimensions are of secondary importance here. Stop bumpers are not to be used as vibration dampers or supports. Safety, quality, and...

Rubber Buffers / Cellular Buffers Program 0170 / 0180 Fall Protection Accidental falling of the stop bumpers is prevented by safeguard measures – so-called “fall protection” – which provides comprehensive safety for man and machine. Cellular bumpers with integrated safety rope and form-fitting, foam-covered cap are used for installation heights > 3 m. Fall protection is a standard feature for all cellular bumpers. The reliable vulcanization process, permanently joining the fastening element to the rubber bumper body, adds to the overall safety of the bumpers. We take special care when...

• Determine the effective mass and impact velocity • Calculate the basic energy formula: W = m x v2 • Determine the energy distribution for each single buffer • Select the needed buffer (cellular or rubber material), depending on general requirements • Select the buffer geometry according to max. buffer energy Wmax from the tables on pages 11, 26, and 27 depending on the bumper type. • Calculate the expected compression length (from diagram - see catalogs “Load Diagrams - Rubber Bumpers” and “Load Diagrams - Cellular Bumpers” on www.conductix.com) • Calculate the resulting reacting force •...

• Mass against mass • Driven mass against limit stop Buffer force-travel diagram • Free fall (this formula does not apply for elevators) • Calculation of buffers for cranes Oscillating masses not taken into account Centrifugal moment of rotating parts must be taken into account Velocity must be reduced according to DIN 15018: v = 100% rated velocity on trolleys v = 85% rated velocity on cranes v = 70% rated velocity on cranes with brakes • Formulas for calculating the deceleration F: Maximum buffer force (kN) mKr: Mass crane without trolley (kg) m1/m2: Mass body 1 / body...

Rubber Buffers Program 0170 General Information Natural caoutchouc rubbers are characterized by their very high elasticity, notch impact resistance, and good abrasion resistance. Among all elastomers, these have the highest mechanical and dynamic load capacities. Natural caoutchouc is not resistant to electrolytic liquids, aliphatic, aromatic hydrocarbons, or chlorinated hydrocarbons. Oil and natural gas are the basic materials for synthetic caoutchouc. For many years, this has been a substitute material for natural caoutchouc, but today synthetic caoutchouc is increasingly used as first...

General Information Rubber-metal elements are used as flexible mechanical fastenings for vibration-free mounting of light to middle-weight machinery. These elements are usually defined geometrically and by hardness and have no determined energy absorption. Application Examples • Machine frames in material handling • Frames with drive and control units in general engineering • Conveyor systems • Machine tools Example Part Number Selection Chart: Materials Selection Chart: Shore Hardness Buffer type- Reference number:- screw length l / thread depth t [mm] Reference number: material...

General Information Cellular buffers have high absorption capacity with long compression lengths. This results in small end loads and favorable deceleration values. Cellular buffers have a compression body made of cellular polyurethane elastomer with high structural stability. Their outstanding characteristic is their volume compressibility, which produces a short transverse elongation under pressure. Cellular buffers are resistant to aliphatic hydrocarbons, such as oils and greases, as well as ozone, UV-radiation, and aging. Technically, you can expect generally high durability. When...
