Problems solved by technology

However, all of these existing solutions respond to the vertical movement of the caster without taking into account whether the forklift is tilted or not.
[0015] At best, previous approaches only improved this trade-off between soft springs and fork wobble versus hard springs and fork damping, which limited the performance of spring-only caster configurations
Another disadvantage of these previously used methods is that the resulting force and movement are fixed

Embodiment Construction

[0030]Various aspects of the invention are described below in connection with improving the stability and vibration control of industrial forklifts. This is because the features and advantages arising from the embodiments of the present invention are well suited for this purpose. Still, it should be appreciated that aspects of the invention may also be used to achieve other objectives.

[0031] Embodiments of the invention described herein, alone or in combination, are suitable for providing dynamically stable forklifts, including, for example, dual-purpose vehicles that can be operated as autonomous robotic vehicles and also as a standard manually-operated forklift forklift. The forklift is stabilized by one or more individual or combined improvements configured to effect motion in any of the three axes and, in some embodiments, coupled with vibration damping. These combined improvements provide protection for sensitive electronic components, increase operator comfort and a...

Abstract

A lift truck includes systems and methods for improved vibration control. Vibration control features reduce or eliminate motion of the truck in one or more of the X-axis, Y-axis, and Z-axis. Some embodiments may include, alone or in combination with the vibration control, stability control to further stabilize the motion of the truck.

Description

[0001] Cross-references to related applications [0002] This application claims to enjoy the right of priority of U.S. provisional patent application NO.61 / 454,188, and its filing date is March 18, 2011, and the title of invention is "Dynamic Stability Control Systems And Methods For Industrial Lift Trucks (for the dynamic stability of industrial forklifts) Control system and method", the content of this patent is incorporated by reference herein. technical field [0003] The present invention relates to the field of industrial forklifts, and more particularly to systems and methods for improving vibration control of forklifts. Background technique [0004] Forklifts are designed in a variety of configurations to perform a variety of tasks. A forklift traveling through a plant may encounter debris and uneven surfaces on the ground. These can take many forms such as expansion joints, cracks in the ground or man-made objects such as ramps between buildings or access to trac...
