Dongling is one of the largest and most innovative manufacturers of air cooled vibration testing systems, with random, sine force ratings from 1kN to 70kN and maximum payloads from 70 kg to as much as 1000 kg. Typical applications of Donglings air cooled electro-dynamic shakers include automotive component testing, electronics product testing, avionics testing and medical research etc

All air-cooled electro-dynamic shakers can be mounted on a single integrated base with a slip table to meet your testing requirements. Dongling also provides turn-key solutions including combined environmental chambers, head expanders and fixtures should you require them.
