Mobile stand

摘要

The stand has a foot (8) fixedly arranged at a mast. A lifting device (12) is pivotably hinged to a pivotal point (10) fixed on the foot such that pivot movement of the lifting device around the pivotal point lowers and/or lifts the foot relative to a roller carrier (4) in a vertical movement. A force assistance device i.e. spring (16), is arranged between the lifting device and the roller carrier for partially compensating torque exerted on the lifting device over the pivotal point from the foot during the pivot movement for lowering the foot. The spring is selected from a group consisting of a coil spring, a bending spring, a torsion spring, a pneumatic spring, a gas pressure spring or an elastomer spring. The foot includes guide pins or thorns directed in a direction of the roller carrier.
