Abstract

Tipping mechanism controls vertical positioned flooring panels into a horizontal position. Portal frame with a central lifting eye is suspended from e.g., a crane. Hydraulic pressure cylinder ram centrally mounted on portal frame actuates via an eccentric and lifting arm, a horizontal shaft which at either end has eccentric discs, grooved to accommodate cables or chains and is connected to eye screwed in end of panel. During tipping operation a sinus form speed curve is obtained, and part of the pressurised fluid above piston in cylinder ram flows to a pressure accumulator, and part to below bottom of piston.
