What Does Casing Pusher Mean?

A casing pusher is on the front of a pneumatic or hydraulic hammer and is used to evenly distribute the thrusting force of the jack to the casing. It makes up the outer diameter of the spoil ejection system. The casing pusher is an essential piece of equipment in trenchless construction.

Also referred to as a master casing pusher.


Trenchlesspedia Explains Casing Pusher

A hydraulic or pneumatic jack drives the casing into place through the earth behind the cutting head. The casing pusher receives and transfers the force from the individual jacks onto the circumference of the casing.

The casing pusher is an integral part of a successful pipe jacking operation as improper alignment of the pusher and/or casing adapter can have drastic effects on the direction of the casing, as well as ensuring that the force of the jacking operation is evenly applied to the casing.
