【発明の名称】油圧駆動道路ローラの運転方法
Document Type and Number:
Japanese Patent JP2989756
Kind Code:
B2
Abstract:
The invention relates to a method for operating a hydraulically driven road roller, primarily for compacting bitumen, with which repeated passes are made over a bitumen coating and in which the roller's speed, acceleration, retardation and direction of travel, forward or in reverse, are selected with an operating lever (1) which, via a control panel (8), electrically acts on hydraulic valves (10, 11, 13) controlling a servo (14) which acts on a hydraulic pump (15) driving the roller's propulsion motors, the operating lever being moveable from a neutral position to full lever deflection and equipped with a forward/reverse switch (2) for selecting the roller's driving direction, and the roller's speed decreases at a programmed retardation rate, when this switch is actuated, until the roller stops, followed by acceleration at a programmed rate to a programmed driving speed in the opposite direction, the roller being brought to a standstill at the maximum permissible retardation rate when the lever is pulled back.
