Emergency Stop Configuration for Hydraulic Ironworker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic ironworkers pose significant safety hazards due to the enormous power and force they generate, necessitating an effective emergency stop mechanism to quickly and completely shut down the machine in case of dangerous situations.
Innovation Solution
The integration of an emergency stop button on the control panel and a remote emergency stop button unit, which, when activated, cuts off all power to the hydraulic ironworker and any attached accessory tools, ensuring immediate shutdown and redundant safety measures through a safety plug assembly and remote push button unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single emergency stop button is provided on the control panel, then the machine can be stopped in emergency situations, but the operator may not be able to access the stop button quickly enough if the control panel is not within reach
Solution Approach 1:
The emergency stop function is segmented into multiple independent locations: a button on the control panel and a separate remote emergency stop button mounted on the machine frame. This segmentation allows operators to access the emergency stop function from different positions, ensuring that at least one button is always within reach regardless of the operator's location or the machine's configuration.
2Reliability
If the remote emergency stop button is always connected to provide redundant safety, then emergency stop accessibility is improved, but the risk of accidental activation or misuse increases
Solution Approach 1:
The system dynamically adjusts the connection state of the remote emergency stop button based on operational context. The button is electrically disconnected when the machine is in certain states (such as during specific operational modes or when safety conditions are not met), preventing accidental activation. When properly connected and safe to use, the button provides redundant emergency stop capability. This dynamic connection management balances accessibility with protection against misuse.

AI summary
One aspect is a hydraulic ironworker system having a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces. An accessory tool is coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker. A remote pushbutton assembly is selectively coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system. A safety plug assembly is configured to alternately couple to the harness assembly in place of the remote pushbutton assembly. Power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies are attached on the harness assembly.
