Telehandler Alignment Adjustment via Electronic Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telehandlers often fail to meet regulatory alignment requirements for road travel due to operator unawareness or errors, requiring laborious and time-consuming manual measurements to ensure correct positioning of the operating arm, tower, and stabilizers.
Innovation Solution
A telehandler equipped with an electronic processing unit that includes sensors and a user interface for guided or automatic adjustment of alignment, allowing operators to easily achieve the required alignment for road travel by transmitting control signals to actuators based on detected positions and target conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used to adjust alignment, then measurement precision can be achieved, but time consumption and operational complexity increase significantly
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated electronic system comprising sensors, processing units, and actuators. The system automatically detects the positions of operating apparatuses, processes alignment data, and actuates components to achieve proper alignment, eliminating the need for manual tape measures and trial-and-error positioning.
Solution Approach 2:
The telehandler system performs self-alignment through integrated sensors that continuously monitor component positions, a processing unit that automatically determines alignment status, and actuators that self-correct misalignments without operator intervention, making the system serve itself for alignment maintenance.
2Ease of operation
If manual alignment adjustment is performed, then alignment can be achieved, but operator error and reliability decrease
Solution Approach 1:
The system incorporates sensors that continuously provide feedback on the positions of operating apparatuses to a processing unit, which compares actual positions against target alignment parameters and automatically makes corrections, ensuring reliable compliance with regulations through closed-loop control.
Solution Approach 2:
The patent replaces human operators' manual alignment tasks with an automated electronic control system that eliminates operator unawareness, approximation errors, and distraction errors, thereby significantly improving reliability and regulatory compliance.
3Productivity
If automated alignment systems are implemented, then productivity and speed improve, but device complexity increases
Solution Approach 1:
The processing unit serves multiple functions: it receives data from various sensors, determines alignment status, compares positions against stored target parameters, and controls multiple actuators. This multi-functionality consolidates what could be separate complex systems into a single integrated control unit.
Solution Approach 2:
The system automatically performs all alignment operations without external intervention, with sensors self-monitoring positions, the processing unit self-determining alignment status, and actuators self-correcting deviations, thereby improving productivity while managing complexity through automation.

AI summary
Described is a telehandler (1) comprising a plurality of operating apparatuses (12, 14, 17, 13, 180, 122), such as, for example, a telescopic operating arm, stabilizers or the like, each operated by one or more actuator devices (19) and electronic processing means (2) which include an acquisition module (21) configured to receive one or more alignment parameters which represent, for the operating apparatuses (12, 14, 17, 13, 180, 122), respective target operating conditions. The telehandler (1) includes detection means (4) for detecting current operating conditions of the operating apparatuses (12, 14, 17, 13, 180, 122) and transmitting corresponding detection signals to the processing means (2), the latter also including a verification module (22) configured to determine, as a function of the detection signals, whether the operating apparatuses (12, 14, 17, 13, 180, 122) are in the respective target operating conditions.
