Other innovations such as the front and rear adjuster, clamping flanges and the fully threaded outer body provide many new options in installation and mounting. Exploit the advantages of this series in your applications with its 505 increased energy capacity and a much wider effective weight range. The effective weight range extends from 9 kg up to 80 000 kg. The MA range models cover the majority of standard applications, whilst the ML range is specially designed for low velocity/high effective weight applications from 300 kg up to 500 000 kg effective weight.
