1 80 Automation ontrol Heavy Industrial Shock Absorbers ffective shock absorption for heavy loads The heavy industrial shock absorbers from A round off the top of the company s offers in damping technology. Designers also have the choice between self-compensating and adjustable machine elements in this category from A. Whichever design is chosen, this type of shock absorber impresses with its robustness and operational readiness wherever heavy loads need reliably stopped on-the-spot at a precise point. The A4 models can absorb up to 6,500 m of energy. The series of heavy duty, self-compensating A types are equally suitable for use as an emergency stop as the adjustable types with the designations A to A. The range of effective loads covered is increased considerably for this purpose. A Stoßdämpfer GmbH. PO Box 50. D Langenfeld. T +49 (0) info@ace-int.eu.

3 8 Heavy Industrial Shock Absorbers Self-ompensating A to A4 Heavy Industrial Shock Absorbers Deceleration of heavy loads Rod Button Powerful: The mass of these high volume absorbers are between.8 and 46 in weight. They complement A s product range of self-compensating shock absorbers. All models from this series are designed for applications where robustness and a large energy absorption are important. The absorbers are designed specifi cally for each customer application with the aid of the A calculation program. The risk of crashes and incorrect settings are therefore prevented The A models can absorb up to 6,500 m of energy and can be used in the area of effective loads between 700 and 6,000. The combination of being extremely solid, absorbing high levels of energy and having a large damping range makes them invaluable. These heavy duty self-compensating industrial shock absorbers are primarily used in heavy mechanical engineering e.g. on lift bridges and steel structures or for damping sluice systems.

7 86 Heavy Industrial Shock Absorbers A½ to A Heavy Industrial Shock Absorbers Deceleration of heavy loads and progressive adjustment Rod Button Strong and adjustable: Also in A s range of units ares heavy duty industrial shock absorbers, which can be adjusted. The models from the A½ to range, which weigh between 7.55 and 5.5, are extremely robust, readyto-install hydraulic machine elements with impressively high energy absorption levels and a wide range of damping rates. Their special aspect is the fl exibility,as all the absorbers can be adjusted using a socket on the absorber base and be perfectly adapted to the required data. The A models cover a range of effective loads from 95 to 04,000 and can absorb up to 44,000 m energy. These heavy duty, adjustable A industrial shock absorbers are the fi rst choice in heavy duty applications and generally in heavy mechanical engineering when the usage data has not been exactly determined.

11 90 Industrial Shock Absorbers / Heavy Industrial Shock Absorbers s for industrial shock absorbers For high cycle rates and extreme temperatures with limited mounting space Shock absorbers convert the introduced energy into heat. The more frequently a shock absorber is stressed per hour, the hotter the oil volume becomes over time. If the requirements placed on the impact frequency of a shock absorber are especially high the use of an air-oil tank is just the right thing. Thanks to the increased oil volume and the resulting heat dissipation, the upper limit of the possible hourly energy capacity of the shock absorber increases significantly. Another characteristic of the air-oil tank is the opportunity for controlled piston return if no permanent return force through an integrated spring in the shock absorber is desired. s AO AO Oil capacity 0 cm Material: Aluminium caps AO Oil capacity 70 cm Material: Steel AO6 Oil capacity,600 cm Material: Steel PT /8" Ø 4 Ø 89 PT /4-4" Ø PT /4-4" Ø 8.5 Detail drawings on request PT /8" PT /4-4" Technical Data Operating pressure: Max. 8 bar Operating temperature range: 80 Damping medium: ATF-Oil 4 cst at 40 Mount air/oil tank higher than shock absorber.
