Abstract

A line striper is attached to a vehicle with a two point hitch and has a swivelable rotatable wheel mounted thereunder to support the striper on the ground. A main beam is releasably clamped and may be slid from side to side depending on operator preference. The gun boom may then be located on the desired side. A delay feature on the control allows the operator to look ahead on a sighting camera and pick the point at which he or she desires striping to start (or stop or any other operation). The controller then compensates for the calibrated distance between the sight point and the spray gun and then starts and stops the gun at the appropriate time given road speed.

Description

[0001] This application is a divisional application of Chinese application number 97111289.4. technical field [0002] The invention relates to a road marking device. Background technique [0003] A road marking device that does not require a dedicated vehicle is described in US Patent No. 5,368,232, the contents of which are incorporated herein by reference. While this device is very effective, one disadvantage is that it only allows a limited amount of weight to be cantilevered from the rear end of the vehicle, especially when the vehicle is small and / or has a relatively low load capacity. Contents of the invention [0004] It is therefore an object of the present invention to provide a device which can be towed on most any vehicle and on which the actual weight of the entire machine is carried. [0005] It is another object of the present invention to provide a road marking device that is easier to set up and operate by one person than many existing devices that requir...
