The tiller is an arm-shaped member mounted on the top of the rudder to turn the rudder. The tiller is a straight handle that fits on the head of the rudder stock. Ancient sailing ships turned the rudder by turning the tiller by hand, while modern ships use the steering gear to turn the tiller.
The steel tiller is fixed to the head of the upper rudder with a key, and the tiller and rudder are turned by manual, mechanical, hydraulic, and other transmission methods. Steel tiller is divided into two types according to their shape, straight tiller, and quadrant tiller. The straight tiller is a straight piece of steel, one end is fixed to the rudder stock, the other end is connected to the chain cable, and the chain cable is pulled to turn the rudder. The straight tiller is divided into longitudinal tiller and transverse tiller according to the installation method.
