FRANKFURT, May 19 U.S. construction machinery maker Terex Corp (TEX.N) launched its hostile $1.31 billion bid for Germany's Demag Cranes D9CGn.DE.
The company said on Thursday Demag Cranes shareholders would have time until June 30 to accept its 41.75 euro-per-share offer for Demag.
Terex this month took its offer directly to shareholders after talks with Demag failed to secure a deal.
The offer represents a 41 percent premium to Demag's closing price on Oct. 6, 2010, before speculation of a possible offer emerged, but was 10 percent below Wednesday's closing price.
Demag cranes traded 0.4 pct higher at 46.81 euros by 0707 GMT on Thursday. (Reporting by Maria Sheahan)
