  We provide a stacky fan description of the total space of certain split
vector bundles, as well as their projectivization, over toric Deligne-Mumford
stacks. We then specialize to the case of Hirzebruch orbifold
$\mathcal{H}_{r}^{ab}$ obtained by projectivizing $\mathcal{O} \oplus
\mathcal{O}(r)$ over the weighted projective line $\mathbb{P}(a,b)$. Next, we
give a combinatorial description of toric sheaves on $\mathcal{H}_{r}^{ab}$ and
investigate their basic properties. With fixed choice of polarization and a
generating sheaf, we describe the fixed point locus of the moduli scheme of
$\mu$-stable torsion free sheaves of rank $1$ and $2$ on
$\mathcal{H}_{r}^{ab}$. As an example, we obtain explicit formulas for
generating functions of Euler characteristics of locally free sheaves of rank 2
on $\mathbb{P}(1,2) \times \mathbb{P}^1$.
