Telehandler Chassis Tilt Control for Automatic Load Levelling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual chassis levelling in telehandlers is slow and unreliable for maintaining load stability when transporting loads over uneven terrain, as it cannot consistently keep the load level during movement.
Innovation Solution
A chassis positioning system with a pivotal connection between the chassis and axle, an actuator, and sensors to automatically adjust the chassis-axle tilt angle based on measured angular positions relative to gravity, allowing for dynamic levelling and anti-roll stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual chassis levelling is used, then the operator can adjust the chassis position, but the levelling process becomes slow and cannot reliably maintain load stability during transport over uneven terrain
Solution Approach 1:
The patent replaces manual mechanical chassis adjustment with an automated electronic control system. Sensors detect the angular position of the chassis and load, and a control unit automatically calculates and adjusts the chassis-axle tilt angle to maintain load stability, eliminating the need for slow manual levelling operations while transporting loads over uneven terrain.
Solution Approach 2:
The system enables the telehandler to automatically self-adjust its chassis position. The control system continuously monitors terrain conditions and load position, then autonomously modifies the chassis-axle tilt angle without operator intervention, allowing the machine to maintain optimal load stability independently during transport.

AI summary
A telehandler (1) comprising: a chassis(10); an axle (20) supporting the chassis(10); a pivotal connection (30) between the axle (20) and the chassis (30); and a chassis positioning system. The pivotal connection (30) is configured to enable rotation of the chassis relative to the axle for varying a chassis-axle tilt angle defined between a longitudinal axis of the axle (20) and the chassis (10). The chassis positioning system comprises: a chassis angle sensor (12) configured to measure an angular position of the chassis relative to gravity; an actuator (13) configured to rotate the chassis (10) relative to the axle (20) at the pivotal connection (30); and a control system configured, in a first mode, to control the actuator (13) to thereby control the chassis-axle tilt angle based on the measured angular position (θ) of the chassis.
