ELECTRONIC PARALLEL LIFT AND ANTI-SPILL ON A BACKHOE LOADER

摘要

A backhoe loader (10) with a controller (100) that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame (12) or with respect to the earth and to maintain the loader bucket angle via controller generated commands to a bucket actuator (60) as a function of the angular signals and commands to a boom actuator (60). The controller (100) enables proportional control of the tool angle via a command input device such as an electronic joystick (21). The controller (100) is capable of maintaining an inclination of the tool (36) with respect to the frame (12). If the boom (31) rises to an angle that is equal to or above a predetermined anti-spill boom angle the controller (100) drives the tool via commands to the tool actuator (60) to a tool angle that is equal to or less than a predetermined anti-spill bucket angle.
