Abstract
This invention relates to a goods-handling cart having chassis provided with a drive and steer wheel together with two swivelling stabilizing wheels, and at least one spring-effect element which acts on both of the stabilizing wheels via a mechanism that transmits a downwardly-directed vertical force to the stabilizing wheels, the mechanism is not attached to the wheels but merely bears thereagainst via simple contact surfaces engaging respective mounting elements for mounting the wheels in such a manner that the mechanism is free to move away from one or other of the mounting elements in a direction opposite to the direction in which the spring-effect element acts; retaining mechanism being associated with each wheel to limit displacement thereof in a downwards direction relative to the chassis.
Claims7
A goods-handling cart comprising;
- a chassis having a longitudinal midplane and provided with a plurality of wheels enabling it to run on the ground, one of the wheels being a drive and steer wheel and being situated in the longitudinal midplane, two other wheels being swivelling stabilizing wheels situated on respective opposite sides of the drive and steer wheel, stabilizing wheel mounting elements for mounting each stabilizing wheel to pivot about a vertical axis and to move vertically relative to the chassis, a mechanism including two levers and an anti-roll bar interconnecting said levers and at least one spring-effect element acting on both stabilizing wheels via said mechanism for transmitting a downwardly-directed vertical force to said stabilizing wheels,
- wherein said stabilizing wheels are free from said mechanism and said mechanism bears via contact surfaces against said stabilizing wheel mounting elements such that said mechanism is free to move away from said corresponding stabilizing wheel mounting elements in a direction opposite to the thrust direction of said spring-effect element, and wherein retaining means are associated with each stabilizing wheel to restrict downwards displacement thereof relative to the chassis.
