AI Technical Summary

Technical Problem

Existing forklift load handling devices rely solely on manual control of clamp arms, making it difficult for operators to apply the precise amount of force needed to securely grip loads without damaging them, especially during movement.

Method used

A smart clamp load handling device equipped with hydraulic actuators, pressure sensors, and an electrical controller that automatically adjusts the force applied by the clamp arms based on load characteristics, ensuring secure gripping without damage.

Benefits of technology

The system provides precise control over the clamping force, reducing the risk of load damage and ensuring safe transport by automatically determining the optimal clamping conditions.

Abstract

Smart clamp load handling device comprising: a first clamp arm (204) and a second clamp arm (205); a first actuator (152) coupled to the first clamp arm (204) and a second actuator (154) coupled to the second clamp arm (205), each actuator (152, 154) comprising a rod-side chamber configured to close the clamp arms (204, 205) when hydraulic fluid is applied to the rod-side chamber, and each actuator (152, 154) comprising a base-side chamber configured to open the clamp arms (204, 205) when hydraulic fluid is applied to the base-side chamber; a first actuator position sensor (176) configured to provide a series of first actuator position measurements; and a second actuator position sensor. (178), which is configured to provide a series of secondary actuator position measurements;a base-side pressure sensor (134) configured to provide a series of base-side pressure measurements; an actuator control valve (130) configured to control the flow of hydraulic fluid to the actuators (152, 154); and an electrical control (120) configured to determine, based on the series of first and second actuator position measurements and the series of base-side pressure measurements, when to stop closing the clamp arms (204, 205), and then to signal the actuator control valve (130) to stop closing the clamp arms (204, 205).
