We propose some channels for the possible observation of anomalousinteractions of the fourth standard model generation quarks at the Large HadronCollider based ep and gamma-p colliders. Namely, u_4 (d_4) -> q gamma and u_4(d_4) -> q Z -> q l^+ l^- decay processes are considered. Signatures forsignals and corresponding standard model backgrounds are investigated at bothcolliders comperatively. The lowest necessary luminosities to observe theseprocesses and the achievable values of the anomalous coupling strengths aredetermined. It is shown that the gamma-p collider is advantageous compare tothe ep collider.
