The present invention relates to a ladder rack (100) for holding a ladder (25), the ladder rack (100) comprising an arm extending longitudinally from a proximal end to a distal end; a slidable member (160) which is slidably mounted on the arm; a first clamp (110) fixed to the arm; a second clamp (120) fixed to the slidable member (160) at a distance from the first clamp (110); a handle (130) pivotally connected to the distal end of the arm; a pivoting member (150) pivotally connected on one end to the handle (130) and on another end to the slidable member (160); whereby upon pivoting the handle (130) upwardly, the pivoting member (150) is forced to pivot at both ends thereof and to push on the slidable member (160), which translates toward the proximal end, reducing the distance between the first clamp (110) and the second clamp (120).
