In the Steam Hall, there are four large rotative engines, all of which have a history of pumping water, plus a number of smaller ancillary engines. All these engines have been lovingly restored and re-erected at the Museum by permanent staff and volunteers.
In the rotative engine, the linear motion of the piston is converted into rotary motion by the crank. The use of both cranks and large flywheels balance out the varying thrusts and loads, thus allowing the engines to operate steadily and smoothly.
