We investigate spt-crank-type functions arising from Bailey pairs. We recall four spt-type functions corresponding to the Bailey pairs $A1$, $A3$, $A5$, and $A7$ of Slater and given four new spt-type functions corresponding to Bailey pairs $C1$, $C5$, $E2$, and $E4$. Each of these functions can be thought of as a count on the number of appearances of the smallest part in certain integer partitions. We prove simple Ramanujan type congruences for these functions that are explained by a spt-crank-type function. The spt-crank-type functions are two variable $q$-series determined by a Bailey pair, that when $z=1$ reduce to the spt-type functions. We find the spt-crank-type functions to have interesting representations as either infinite products or as Hecke-Rogers-type double series. These series reduce nicely when $z$ is a certain root of unity and allow us to deduce the congruences. Additionally we find dissections when $z$ is a certain root of unity to give another proof of the congruences. Our double sum and product formulas require Bailey's Lemma and conjugate Bailey pairs. Our dissection formulas follow from Bailey's Lemma and dissections of known ranks and cranks.
