Broker (construction)

A leader is the guiding device of a pile driver in civil engineering that brings pipes or sheet piles into the ground. In contrast to installation by means of a free-running pile-driving or vibration device, greater accuracy is achieved, especially with greater lengths of the sheet pile walls to be installed.

There are different types of construction such as the telescopic leader, the fixed leader and the universal leader.
