General information Cellular buffers have a strong absorption capacity with long compression length. As a result they produce low limit forces and favorable deceleration values. Cellular buffers are made up of a spring body made of cellular Polyurethane-Elastomere with high structural stability. Their outstanding characteristic is their volume compressibility, which produces a low transverse elongation under pressure. Cellular buffers are resistant against aliphatic hydrocarbons, such as oils and greases as well as ozone, UV-radiation and aging. You can expect a general resistance in technical application. The cellular body is only limited resistant against hydraulic oil and degenerates when exposed to hot water and water vapor over a longer period. Cellular buffers are not resistant to strong acids and leaches. The operating temperature is between -20ºC and +80ºC. Temporary temperature peaks of +00 C are practicable and do not harm the buffer. When exposed to -20 C the material becomes harder, which does however not affect the consistency of the material. The mounting structure must be flat and rigidly. In order the buffer is an area of,5 x diameters for the diameter increase with compression to be considered. 2 Examples of application Crane systems, storage and retrieval machines, smelter and rolling mill machines, handling technique, plant construction and engineering, hoist systems. Conveyor, transport and gate systems that are equipped with form-locking drives (e.g. chain or toothed rack). Lift buffers for vertically moved loads such as hoists and counter weights. 3 Conductix-Wampfler standard cellular buffer quality Cellular Polyurethane-Elastomere with a volumetric weight of 0.53 g/cm 3 Resilient and tear resistant Age resistant Material is volume compressible Operating temperature: -20 C to +80 C Special qualities and special constructions on inquiry. www.conductix.com Page 2 of 6
Cellular buffers product group 08 and 082 (see item 5.). The compatible type without safety device (08) was stopped for the avoidance of the confounding danger. The series 082 with integrated safety device against can be used over 3 m height. The sizes up to 200 mm of buffer diameters are the base plates from glass fiber reinforced plastic and integrated safety against falling equipped. Starting from size 250 (optionally with size 200) the base plates from steel are two-way primed and. Buffer plate and body stucked together. These buffers have a cable safety device against crash of the buffer body within the range of the center line with failure of the sticking seam by environmental condition. For use as safety element please consider the valid regulation for the final product and the result of the risk analyse for this task. Recommended exchange interval: 5 years for safety-relevant applications. 4 Quality degrees Abrasion resistance 2 Breaking elongation 2 Tear resistance 2 Rebound resistance 2 Tensile strength 2 Temp. resistance hot air +80 C Temp. resistance coldness -20 C Alkali resistance 4 Age resistance 2 Gasoline resistance 4 Electrical insulation resistance 3 Oil and grease resistance 2 Ozone resistance Acid resistance 6 Hot water 3 Quality degrees: = very good; 2 = good; 3 = satisfying; 4 = sufficient; 5 = deficient; 6 = insufficient International abbreviation: PUR (cellular Polyurethane-Elastomere) www.conductix.com Page 3 of 6

5.3 Lift buffer with steel plate The design check for the lift buffers listed in the table has been made according to the hoisting directives 95/6/EG. The permissible load zones are documented for each lift buffer type by the certificate No. An EC design check certificate can be provided for each lift buffer type. Lifts with lower speed than the maximum nominal speed taken as a basis for the design check, are for the same load zone, when the loads from cabin / working load or counter load are within the values m max and m min.
