  Transverse momentum spectra, $d^2\sigma/(d\eta dp_T^2)$, of charged hadron
production in $pp$-collisions are considered in terms of a recently introduced
two component model. The shapes of the particle distributions vary as a
function of c.m.s. energy in the collision and the measured pseudorapidity
interval. In order to extract predictions on the double-differential
cross-sections $d^2\sigma/(d\eta dp_T^2)$ of hadron production for future
LHC-measurements the different sets of available experimental data have been
used in this study.
