To prevent significant loss of the luminosity due to this large crossing angle, the design of the collider requires the use of groups of crab cavities to provide local crabbing for both proton/ion and electron beams. We will base our design for eRHIC crab cavities based on our experience in the design of the 400 MHz double quarter wave crab cavity (DQWCC) for the Hi-Lumi upgrade of the Large Hadron Collider at CERN. This DQWCC design is scaled to different frequencies of a main crab cavity and its higher harmonics for eRHIC. In this paper, we discuss the preliminary designs of the eRHIC crab cavities and their major parameters.
