Abstract

A trolley, esp. for locating a blast nozzle on a blast furnace tuyere, and also for removing the nozzle is fitted with a hoist which raises or lowers a cradle on which the nozzle rests. The hoist consists of two pairs of levers mounted on pivots to lower or raise the cradle. The hoist is also fitted with horizontal pivots so the cradle can be tilted to swing the nozzle into the desired position using a hand lever. The trolley has guides controlling the movement of the scissor levers.
