Abstract
A pile driving device for driving a pile into the ground comprises a ram, an anvil and a sleeve. The anvil is accommodated in the sleeve and movable with respect to the sleeve in a driving direction. The ram is reciprocatingly movable with respect to the anvil in the driving direction so as to provide impact energy to the anvil under operating conditions. The anvil and the sleeve contact each other in transverse direction of the driving direction through an anvil guide surface of an anvil guide. The anvil guide is a separate anvil guide that is mounted to one of the anvil and the sleeve such that the anvil guide surface is movable with respect to said one of the anvil and the sleeve in the transverse direction.

A pile driving device for driving a pile into the ground, comprising a ram, an anvil and a sleeve, wherein the anvil is accommodated in the sleeve and movable with respect to the sleeve in a driving direction, wherein the ram is reciprocatingly movable with respect to the anvil in the driving direction so as to provide impact energy to the anvil under operating conditions, wherein the anvil and the sleeve contact each other in a transverse direction of the driving direction through an anvil guide surface of an anvil guide, being a separate anvil guide that is mounted to one of the anvil and the sleeve such that the anvil guide surface is movable with respect to said one of the anvil and the sleeve in the transverse direction.
A follower for use in combination with a pile driving device comprising a ram, an anvil and a sleeve, wherein the anvil is accommodated in the sleeve and movable with respect to the sleeve in a driving direction, wherein the follower is suitable to be placed onto a pile such that the anvil is placed indirectly onto the pile through the follower under operating conditions, wherein the follower is a tubular follower including a centerline which is directed in the same direction as the driving direction, wherein the follower is provided with stress relieve slots which are located at a circumference of the follower, wherein the longitudinal directions of the stress relieve slots are parallel to the centerline of the follower.
