No it was a Roman custom that the person who was going to be crucified should carry his own cross.--Some scripture, and most tradition, tells us that the Romans laid Jesus' cross on a Cyrenian named Simon.
As Jesus fell several times on the way to Calvary as he was exhausted , it was then that the roman soldier told Simon to carry it.
The Roman authorities were responsible for hanging Jesus on the cross.
Jesus was put on the cross by the Roman authorities, specifically by the order of Pontius Pilate, the Roman governor of Judea at the time.
Roman soldiers
When Jesus was on the cross no knife was used by the roman soldier , he used his spear.
Jesus Christ died on a Roman Cross, by crucifixion.

Carrying the cross (possibly just the crossbar) was standard practice in Roman crucificxions, to further humiliate the victim, so that he could be seen by the public as a criminal on his way to the place of execution. The Romans wanted to frighten the population, since there were many 'freedom' movements in Palestine at the time (sounds familiar!).
Jesus was crucified on a Roman cross, not a tree, but undoubtedly made of wood. The reference to being hung on a tree relates to the fact that the cross was made of wood.
I'm assuming you're meaning Simon the Cyrenean. I believe he was a Jew who happened to be in Jerusalem for the Passover and was chosen by a Roman soldier to carry Jesus' cross.
It was the Roman's style worst way of execution. When Pontius Pilate said he saw nothing wrong with Jesus, he just wanted to keep his seat, so he threw them over to the Romans. Jesus tells us to Carry Our Cross Daily. That is our burdens, but the cross is actually evened out exactly. Even when Christ was carrying His cross, they called on a Samaritan to help Him. Jesus still helps us carry our cross today.
